ToggleButton

Toggle button UI component

Description

A toggle button UI component allows an app user to select one of a group of options from within a button group. Use the ToggleButton object to modify the appearance and behavior of a toggle button after you create it.

Creation

Create a toggle button in an app using the uitogglebutton function.

Button

`Value` — State of toggle button
1 | 0

State of the toggle button specified as 0 (unpressed) or 1 (depressed). Within a given button group, only one toggle button can be selected (depressed) at a time. When the Value property is set to 1, the toggle button appears depressed. The state of the first button added to a button group is 1, by default. Subsequent buttons added to the same button group have a default state of 0.

When the Value property of a ToggleButton changes to 1, the Value property of the previously selected ToggleButton changes to 0. In addition, the SelectedObject property value of the ButtonGroup is updated.

If you programmatically change the Value property of a ToggleButton to 0, MATLAB^® sets the Value property of the first ToggleButton added to the ButtonGroup to 1. If the first ToggleButton added is the one for which you programmatically set the Value property to 0, then MATLAB sets the Value property for the ToggleButton added to the ButtonGroup to 1.

Note

The first ToggleButton added to a ButtonGroup is not necessarily the first ToggleButton listed in the Children property of the ButtonGroup.

`Text` — Button label
`'Toggle Button'` (default) | character vector | cell array of character vectors | string scalar | string array | ...

Button label, specified as a character vector, cell array of character vectors, string scalar, string array, or 1-D categorical array. Specify a character vector or string scalar to label the button with a single line of text. Use a cell array or string array to label the button with multiple lines of text. Each element in the array represents a separate line of text. If you specify this property as a categorical array, MATLAB uses the values in the array, not the full set of categories.

`Interpreter` — Button text interpreter
`'none'` (default) | `'tex'` | `'latex'` | `'html'`

Button text interpreter, specified as:

'none' — Display literal characters.
'tex'— Interpret text using a subset of TeX markup.
'latex'— Interpret text using a subset of LaTeX markup.
'html'— Interpret text using a subset of HTML markup.

TeX Markup

Use TeX markup to add superscripts and subscripts and to include special characters in the text.

Modifiers remain in effect until the end of the text. Superscripts and subscripts are an exception because they modify only the next character or the characters within the curly braces. When you set the interpreter to 'tex', the supported modifiers are as follows.

Modifier	Description	Example
`^{ }`	Superscript	`'text^{superscript}'`
`_{ }`	Subscript	`'text_{subscript}'`
`\bf`	Bold font	`'\bf text'`
`\it`	Italic font	`'\it text'`
`\sl`	Oblique font (usually the same as italic font)	`'\sl text'`
`\rm`	Normal font	`'\rm text'`
`\fontname{specifier}`	Font name — Replace `specifier` with the name of a font family. You can use this in combination with other modifiers.	`'\fontname{Courier} text'`
`\fontsize{specifier}`	Font size —Replace `specifier` with a numeric scalar value in point units.	`'\fontsize{15} text'`
`\color{specifier}`	Font color — Replace `specifier` with one of these colors: `red`, `green`, `yellow`, `magenta`, `blue`, `black`, `white`, `gray`, `darkGreen`, `orange`, or `lightBlue`.	`'\color{magenta} text'`
`\color[rgb]{specifier}`	Custom font color — Replace `specifier` with a three-element RGB triplet.	`'\color[rgb]{0,0.5,0.5} text'`

This table lists the supported special characters for the 'tex' interpreter.

LaTeX Markup

To use LaTeX markup, set the interpreter to 'latex'. Use LaTeX markup to format and display mathematical expressions, equations, and special characters. Use dollar symbols around the marked up text. For example, use '$\int_1^{20} x^2 dx$' for inline mode or '$$\int_1^{20} x^2 dx$$' for display mode.

The displayed text uses the default LaTeX font style. The FontName, FontWeight, and FontAngle properties do not have an effect. To change the font style, use LaTeX markup.

MATLAB supports most standard LaTeX math mode commands. For more information, see Supported LaTeX Commands.

HTML Markup

To use HTML markup, set the interpreter to 'html'. Setting font styles using HTML overrides any equivalent font properties. For example, this code creates a toggle button with red text.

fig = uifigure;
bg = uibuttongroup(fig);
tb = uitogglebutton(bg,"Interpreter","html");
tb.Text = '<p style="color: red;">Text</p>';
tb.FontColor = "blue";

The interpreter supports a subset of HTML markup. As a general guideline, the interpreter supports text-related tags and styles. Unsupported tags and styles are ignored.

`WordWrap` — Word wrapping to fit component width
`'off'` (default) | on/off logical value

Word wrapping to fit component width, specified as 'off' or 'on', or as numeric or logical 0 (false) or 1 (true). A value of 'off' is equivalent to false, and 'on' is equivalent to true. Thus, you can use the value of this property as a logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.

Use this property to prevent text from getting clipped horizontally when the width of the component is smaller than the text you want to display.

'off' — Text does not wrap.
'on' — Breaks text into new lines so that each line fits within the width of the component and avoids breaking words when possible.

Setting the WordWrap property to 'on' does not prevent text from getting clipped vertically when the height of the component is too small to display all the lines of text.

`Icon` — Predefined or custom icon
`''` (default) | character vector | string scalar | `m`-by-`n`-by-3 truecolor image array

Predefined or custom icon, specified as a character vector, string scalar, or m-by-n-by-3 truecolor image array.

Predefined Icon

This table lists the values to specify the predefined icons.

Value	Icon
`''` (default)	No icon displays.
`'question'`
`'info'`
`'success'`
`'warning'`
`'error'`

Custom Icon

Specify a custom icon as one of these values:

A character vector or string scalar that specifies the file name of an SVG, JPEG, GIF, or PNG image that is on the MATLAB path. Alternatively, you can specify a full path to the image file.
An m-by-n-by-3 truecolor image array. See Working with Image Types in MATLAB for more information.

If you plan to share an app with others, put the image file on the MATLAB path to facilitate app packaging.

If the button text takes up all the space specified by the Position property value, then MATLAB does not display the icon. If some room is available for the icon, then MATLAB scales down the image to fit, if necessary.

Font and Color

`FontName` — Font name
system supported font name

Font name, specified as a system supported font name. The default font depends on the specific operating system and locale.

If the specified font is not available, then MATLAB uses the best match among the fonts available on the system where the app is running.

Example: 'Arial'

`FontSize` — Font size
positive number

Font size, specified as a positive number. The units of measurement are pixels. The default font size depends on the specific operating system and locale.

Example: 14

`FontWeight` — Font weight
`'normal'` (default) | `'bold'`

Font weight, specified as one of these values:

'normal' — Default weight as defined by the particular font
'bold' — Thicker character outlines than 'normal'

Not all fonts have a bold font weight. For fonts that do not, specifying 'bold' results in the normal font weight.

`FontAngle` — Font angle
`'normal'` (default) | `'italic'`

Font angle, specified as 'normal' or 'italic'. Not all fonts have an italic font angle. For fonts that do not, specifying 'italic' results in the normal font angle.

`FontColor` — Font color
`[0 0 0]` (default) | RGB triplet | hexadecimal color code | `'r'` | `'g'` | `'b'` | ...

Font color, specified as an RGB triplet, a hexadecimal color code, or one of the options listed in the table.

RGB triplets and hexadecimal color codes are useful for specifying custom colors.

An RGB triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of the color. The intensities must be in the range [0,1]; for example,[0.4 0.6 0.7].
A hexadecimal color code is a character vector or a string scalar that starts with a hash symbol (#) followed by three or six hexadecimal digits, which can range from 0 to F. The values are not case sensitive. Thus, the color codes "#FF8800", "#ff8800", "#F80", and "#f80" are equivalent.

Alternatively, you can specify some common colors by name. This table lists the named color options, the equivalent RGB triplets, and hexadecimal color codes.

Color Name	Short Name	RGB Triplet	Hexadecimal Color Code
`"red"`	`"r"`	`[1 0 0]`	`"#FF0000"`
`"green"`	`"g"`	`[0 1 0]`	`"#00FF00"`
`"blue"`	`"b"`	`[0 0 1]`	`"#0000FF"`
`"cyan"`	`"c"`	`[0 1 1]`	`"#00FFFF"`
`"magenta"`	`"m"`	`[1 0 1]`	`"#FF00FF"`
`"yellow"`	`"y"`	`[1 1 0]`	`"#FFFF00"`
`"black"`	`"k"`	`[0 0 0]`	`"#000000"`
`"white"`	`"w"`	`[1 1 1]`	`"#FFFFFF"`

Here are the RGB triplets and hexadecimal color codes for the default colors MATLAB uses in many types of plots.

RGB Triplet	Hexadecimal Color Code	Appearance
`[0 0.4470 0.7410]`	`"#0072BD"`
`[0.8500 0.3250 0.0980]`	`"#D95319"`

`[0.3010 0.7450 0.9330]`	`"#4DBEEE"`
`[0.6350 0.0780 0.1840]`	`"#A2142F"`

`BackgroundColor` — Background color
`[0.96 0.96 0.96]` (default) | RGB triplet | hexadecimal color code | `'r'` | `'g'` | `'b'` | ...

Background color, specified as an RGB triplet, a hexadecimal color code, or one of the color options listed in the table.

RGB triplets and hexadecimal color codes are useful for specifying custom colors.

An RGB triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of the color. The intensities must be in the range [0,1]; for example,[0.4 0.6 0.7].
A hexadecimal color code is a character vector or a string scalar that starts with a hash symbol (#) followed by three or six hexadecimal digits, which can range from 0 to F. The values are not case sensitive. Thus, the color codes "#FF8800", "#ff8800", "#F80", and "#f80" are equivalent.

Alternatively, you can specify some common colors by name. This table lists the named color options, the equivalent RGB triplets, and hexadecimal color codes.

Color Name	Short Name	RGB Triplet	Hexadecimal Color Code
`"red"`	`"r"`	`[1 0 0]`	`"#FF0000"`
`"green"`	`"g"`	`[0 1 0]`	`"#00FF00"`
`"blue"`	`"b"`	`[0 0 1]`	`"#0000FF"`

`"black"`	`"k"`	`[0 0 0]`	`"#000000"`
`"white"`	`"w"`	`[1 1 1]`	`"#FFFFFF"`

Here are the RGB triplets and hexadecimal color codes for the default colors MATLAB uses in many types of plots.

RGB Triplet	Hexadecimal Color Code	Appearance

`[0.6350 0.0780 0.1840]`	`"#A2142F"`

Interactivity

`Visible` — State of visibility
`'on'` (default) | on/off logical value

State of visibility, specified as 'on' or 'off', or as numeric or logical 1 (true) or 0 (false). A value of 'on' is equivalent to true, and 'off' is equivalent to false. Thus, you can use the value of this property as a logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.

'on' — Display the object.
'off' — Hide the object without deleting it. You still can access the properties of an invisible UI component.

To make your app start faster, set the Visible property to 'off' for all UI components that do not need to appear at startup.

`Enable` — Operational state of button
`'on'` (default) | on/off logical value

Operational state of the button, specified as 'on' or 'off', or as numeric or logical 1 (true) or 0 (false). A value of 'on' is equivalent to true, and 'off' is equivalent to false. Thus, you can use the value of this property as a logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.

If you set this property to 'on', then the appearance of the button indicates that the app user can interact with it.
If you set this property to 'off', then the appearance of the button appears dimmed, indicating that the app user cannot interact with it.

`Tooltip` — Tooltip
`''` (default) | character vector | cell array of character vectors | string array | 1-D categorical array

Tooltip, specified as a character vector, cell array of character vectors, string array, or 1-D categorical array. Use this property to display a message when the user hovers the pointer over the component at run time. The tooltip displays even when the component is disabled. To display multiple lines of text, specify a cell array of character vectors or a string array. Each element in the array becomes a separate line of text. If you specify this property as a categorical array, MATLAB uses the values in the array, not the full set of categories.

`ContextMenu` — Context menu
empty `GraphicsPlaceholder` array (default) | `ContextMenu` object

Context menu, specified as a ContextMenu object created using the uicontextmenu function. Use this property to display a context menu when you right-click on a component.

Position

`Position` — Location and size of button
`[10 40 100 22]` (default) | `[left bottom width height]`

Location and size button, specified as a vector of the form [left bottom width height]. This table describes each element in the vector.

Element	Description
`left`	Distance from the inner left edge of the button group to the outer left edge of the button
`bottom`	Distance from the inner bottom edge of the button group to the outer bottom edge of the button
`width`	Distance between the right and left outer edges of the button
`height`	Distance between the top and bottom outer edges of the button

The Position values are relative to the drawable area of the button group. The drawable area is the area inside the borders of the button group and does not include the area occupied by the title.

All measurements are in pixel units.

`InnerPosition` — Location and size of button
`[10 10 100 22]` (default) | `[left bottom width height]`

Location and size of button, specified as a four element vector of the form [left bottom width height]. All measurements are in pixel units. This property value is identical to the Position property.

`OuterPosition` — Outer location and size of button
`[10 10 100 22]` (default) | `[left bottom width height]`

This property is read-only.

Location and size of button, returned as a four element vector of the form [left bottom width height]. All measurements are in pixel units. This property value is identical to the Position property.

`HorizontalAlignment` — Horizontal alignment of icon and text
`'center'` (default) | `'left'` | `'right'`

Horizontal alignment of the icon and text, specified as 'center', 'left', or 'right'. The horizontal alignment is relative to the area inside the borders of the button. Setting this property when the text spans the full width of the button has no apparent effect in the UI.

`VerticalAlignment` — Vertical alignment of icon and text
`'center'` (default) | `'top'` | `'bottom'`

Vertical alignment of the icon and the text, specified as 'center', 'top', or 'bottom'. The vertical alignment is relative to the area inside the borders of the button. Setting this property when the text height fills the height of the button has no apparent effect in the UI.

`IconAlignment` — Location of button icon
`'left'` (default) | `'right'` | `'center'` | `'leftmargin'` | `'rightmargin'` | `'top'` | `'bottom'`

Location of the button icon, specified as one of the values in the table. The examples in the table show the result of specifying each IconAlignment value for a button with a HorizontalAlignment value of 'center'.

Value	Description	Example
`'left'`	The icon displays directly to the left of the button text.
`'right'`	The icon displays directly to the right of the button text.
`'center'`	The icon displays at the center of the button, behind the text.
`'leftmargin'`	The icon displays on the far left of the button, regardless of the text location. This value is equivalent to `'left'` when the value of `HorizontalAlignment` is `'left'`.
`'rightmargin'`	The icon displays on the far right of the button, regardless of the text location. This value is equivalent to `'right'` when the value of `HorizontalAlignment` is `'right'`.
`'top'`	The icon displays directly above the button text.
`'bottom'`	The icon displays directly below the button text.

If the Text property of the button is empty, then the icon location is determined by the HorizontalAlignment and VerticalAlignment properties instead of the IconAlignment property.

Callbacks

`CreateFcn` — Creation function
`''` (default) | function handle | cell array | character vector

Object creation function, specified as one of these values:

Function handle.
Cell array in which the first element is a function handle. Subsequent elements in the cell array are the arguments to pass to the callback function.
Character vector containing a valid MATLAB expression (not recommended). MATLAB evaluates this expression in the base workspace.

For more information about specifying a callback as a function handle, cell array, or character vector, see Callbacks in App Designer.

This property specifies a callback function to execute when MATLAB creates the object. MATLAB initializes all property values before executing the CreateFcn callback. If you do not specify the CreateFcn property, then MATLAB executes a default creation function.

Setting the CreateFcn property on an existing component has no effect.

If you specify this property as a function handle or cell array, you can access the object that is being created using the first argument of the callback function. Otherwise, use the gcbo function to access the object.

`DeleteFcn` — Deletion function
`''` (default) | function handle | cell array | character vector

Object deletion function, specified as one of these values:

Function handle.
Cell array in which the first element is a function handle. Subsequent elements in the cell array are the arguments to pass to the callback function.
Character vector containing a valid MATLAB expression (not recommended). MATLAB evaluates this expression in the base workspace.

For more information about specifying a callback as a function handle, cell array, or character vector, see Callbacks in App Designer.

This property specifies a callback function to execute when MATLAB deletes the object. MATLAB executes the DeleteFcn callback before destroying the properties of the object. If you do not specify the DeleteFcn property, then MATLAB executes a default deletion function.

If you specify this property as a function handle or cell array, you can access the object that is being deleted using the first argument of the callback function. Otherwise, use the gcbo function to access the object.

Callback Execution Control

`Interruptible` — Callback interruption
`'on'` (default) | on/off logical value

Callback interruption, specified as 'on' or 'off', or as numeric or logical 1 (true) or 0 (false). A value of 'on' is equivalent to true, and 'off' is equivalent to false. Thus, you can use the value of this property as a logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.

This property determines if a running callback can be interrupted. There are two callback states to consider:

The running callback is the currently executing callback.
The interrupting callback is a callback that tries to interrupt the running callback.

MATLAB determines callback interruption behavior whenever it executes a command that processes the callback queue. These commands include drawnow, figure, uifigure, getframe, waitfor, and pause.

If the running callback does not contain one of these commands, then no interruption occurs. MATLAB first finishes executing the running callback, and later executes the interrupting callback.

If the running callback does contain one of these commands, then the Interruptible property of the object that owns the running callback determines if the interruption occurs:

If the value of Interruptible is 'off', then no interruption occurs. Instead, the BusyAction property of the object that owns the interrupting callback determines if the interrupting callback is discarded or added to the callback queue.
If the value of Interruptible is 'on', then the interruption occurs. The next time MATLAB processes the callback queue, it stops the execution of the running callback and executes the interrupting callback. After the interrupting callback completes, MATLAB then resumes executing the running callback.

Note

Callback interruption and execution behave differently in these situations:

If the interrupting callback is a DeleteFcn, CloseRequestFcn, or SizeChangedFcn callback, then the interruption occurs regardless of the Interruptible property value.
If the running callback is currently executing the waitfor function, then the interruption occurs regardless of the Interruptible property value.
If the interrupting callback is owned by a Timer object, then the callback executes according to schedule regardless of the Interruptible property value.

Note

When an interruption occurs, MATLAB does not save the state of properties or the display. For example, the object returned by the gca or gcf command might change when another callback executes.

`BusyAction` — Callback queuing
`'queue'` (default) | `'cancel'`

Callback queuing, specified as 'queue' or 'cancel'. The BusyAction property determines how MATLAB handles the execution of interrupting callbacks. There are two callback states to consider:

The running callback is the currently executing callback.
The interrupting callback is a callback that tries to interrupt the running callback.

The BusyAction property determines callback queuing behavior only when both of these conditions are met:

The running callback contains a command that processes the callback queue, such as drawnow, figure, uifigure, getframe, waitfor, or pause.
The value of the Interruptible property of the object that owns the running callback is 'off'.

Under these conditions, the BusyAction property of the object that owns the interrupting callback determines how MATLAB handles the interrupting callback. These are possible values of the BusyAction property:

'queue' — Puts the interrupting callback in a queue to be processed after the running callback finishes execution.
'cancel' — Does not execute the interrupting callback.

`BeingDeleted` — Deletion status
on/off logical value

This property is read-only.

Deletion status, returned as an on/off logical value of type matlab.lang.OnOffSwitchState.

MATLAB sets the BeingDeleted property to 'on' when the DeleteFcn callback begins execution. The BeingDeleted property remains set to 'on' until the component object no longer exists.

Check the value of the BeingDeleted property to verify that the object is not about to be deleted before querying or modifying it.

Parent/Child

`Parent` — Parent container
`ButtonGroup` object

Parent container, specified as a ButtonGroup object. The ButtonGroup must be in a Figure created using the uifigure function.

`HandleVisibility` — Visibility of object handle
`'on'` (default) | `'callback'` | `'off'`

Visibility of the object handle, specified as 'on', 'callback', or 'off'.

This property controls the visibility of the object in its parent's list of children. When an object is not visible in its parent's list of children, it is not returned by functions that obtain objects by searching the object hierarchy or querying properties. These functions include get, findobj, clf, and close. Objects are valid even if they are not visible. If you can access an object, you can set and get its properties, and pass it to any function that operates on objects.

HandleVisibility Value	Description
`'on'`	The object is always visible.
`'callback'`	The object is visible from within callbacks or functions invoked by callbacks, but not from within functions invoked from the command line. This option blocks access to the object at the command-line, but allows callback functions to access it.
`'off'`	The object is invisible at all times. This option is useful for preventing unintended changes to the UI by another function. Set the `HandleVisibility` to `'off'` to temporarily hide the object during the execution of that function.

Identifiers

`Type` — Type of graphics object
`'uitogglebutton'`

This property is read-only.

Type of graphics object, returned as 'uitogglebutton'.

`Tag` — Object identifier
`''` (default) | character vector | string scalar

Object identifier, specified as a character vector or string scalar. You can specify a unique Tag value to serve as an identifier for an object. When you need access to the object elsewhere in your code, you can use the findobj function to search for the object based on the Tag value.

`UserData` — User data
`[]` (default) | array

User data, specified as any MATLAB array. For example, you can specify a scalar, vector, matrix, cell array, character array, table, or structure. Use this property to store arbitrary data on an object.

If you are working in App Designer, create public or private properties in the app to share data instead of using the UserData property. For more information, see Share Data Within App Designer Apps.

Create Toggle Buttons, Set and Access Property Values

Create toggle buttons by first creating a figure window and a button group to contain the buttons.

fig = uifigure('Position',[680 678 398 271]);
bg = uibuttongroup(fig,'Position',[137 113 123 85]);

Create three toggle buttons and specify the location of each.

tb1 = uitogglebutton(bg,'Position',[10 50 100 22]);
tb2 = uitogglebutton(bg,'Position',[10 28 100 22]);
tb3 = uitogglebutton(bg,'Position',[10 6 100 22]);

Three toggle buttons in a button group. Each button has the text "Toggle Button" and the first button is selected.

Change the text associated with each toggle button.

tb1.Text = 'English';
tb2.Text = 'French';
tb3.Text = 'German';

Three toggle buttons in a button group. The buttons have the text "English", "French", and "German". The "English" button is selected.

Change the toggle button selection to German programmatically.

tb3.Value = true;

Three toggle buttons in a button group. The buttons have the text "English", "French", and "German". The "German" button is selected.

Determine the font name of the German toggle button text.

font = tb3.FontName

font =

Helvetica

R2024b: Specify HTML markup and display equations in text

Enable text markup by setting the Interpreter property. Specify the interpreter as "html", "latex", "tex", or "none".

R2022b: Specify additional icon and icon alignment options

You can use these additional options when adding icons to a button:

Specify the Icon property as a predefined icon, such as 'success'.
Specify the IconAlignment property as 'leftmargin' or 'rightmargin' to display the icon on the far left or far right of the button, regardless of the button text location.

R2020b: Wrap button text

Use the WordWrap property to prevent text from getting clipped horizontally when the width of the UI component is smaller than the text you want to display. Setting the WordWrap property to 'on' breaks the text into new lines so that each line fits within the component. It avoids breaking words when possible. When the property is set to 'off', the text does not wrap.
