Get component position in pixels

    Syntax

    pos = getpixelposition(c)
    pos = getpixelposition(c,isrecursive)

    Description

    pos = getpixelposition(c) returns the position in pixels of the component specified by c. MATLAB® returns the position as a four-element vector that specifies the location and size of the component relative to its parent container in the form [left bottom width height].

    example

    pos = getpixelposition(c,isrecursive), where isrecursive is true, returns the component position relative to the parent figure. The default for isrecursive is false, which returns the position relative to its immediate parent container.

    example

    Examples

    collapse all

    Create a push button within a panel container.

    f = figure('Position',[300 300 300 200]);
p = uipanel('Position',[.2 .2 .6 .6]);
btn = uicontrol(p,'Style','PushButton', ...
     'Units','Normalized', ...
     'String','Push Button', ...
     'Position',[.1 .1 .5 .2]);

    Figure window containing a panel with a push button

    Get the position in pixels of the push button relative to its parent container, the panel.

    pos = getpixelposition(btn)

    pos =

   18.6000   12.6000   88.0000   23.2000

    Create a push button within a panel container.

    f = figure('Position',[300 300 300 200]);
p = uipanel('Position',[.2 .2 .6 .6]);
btn = uicontrol(p,'Style','PushButton', ...
     'Units','Normalized', ...
     'String','Push Button', ...
     'Position',[.1 .1 .5 .2]);

    Figure window containing a panel with a push button

    Get the position in pixels of the push button relative to its parent figure.

    pos = getpixelposition(btn,true)

    pos1 =
      80.6000   54.6000   88.0000   23.2000

    Input Arguments

    collapse all

    UI component.

    Whether to return the position relative to the parent figure, specified as a numeric or logical 0 (false) or 1 (true).

    • 0 (false) — The function returns the component position relative to its immediate parent.

    • 1 (true) — The function returns the component position relative to the figure window.

    Pixels

    Distances in pixels are independent of your system resolution on Windows® and Macintosh systems:

    • On Windows systems, MATLAB defines a pixel as 1/96th of an inch.

    • On Macintosh systems, MATLAB defines a pixel as 1/72nd of an inch.

    On Linux® systems, your system resolution determines the size of a MATLAB pixel. For more information, see DPI-Aware Behavior in MATLAB.
