uif = uifigure;
uig = uigridlayout('Parent', uif, ...
                   'ColumnWidth', repmat({'1x'}, 1, 5), ...
                   'RowHeight', repmat({'1x'}, 1, 3));
uib = uibutton('Parent', uig, ...
               'Text', 'I want to be placed in one line')
% Put this lines inside 'uibutton' initialisation:
uib.Layout.Column = 3;
uib.Layout.Row = 2;

I searched for something able to create an instance of GridLayoutOptions, but i can't find anything.

An alternative would be to understand how matlab.ui.layout.LayoutOptions would accept inputs.

I ran into this same problem today, and found a solution. The above answer is a little misleading. You can place an obect in a uigridlayout in one line. For instance using your code to start, I place the uibutton on Row 2 and Column 3 of the uigridlayout in one line.

uif = uifigure;
uig = uigridlayout('Parent', uif, ...
                   'ColumnWidth', repmat({'1x'}, 1, 5), ...
                   'RowHeight', repmat({'1x'}, 1, 3));
uib = uibutton('Parent', uig, ...
               'Text', 'I am being placed in one line','Layout', ...
               matlab.ui.layout.GridLayoutOptions('Row',2,'Column',3));

Here, I use matlab.ui.layout.GridLayoutOptions to create a GridLayoutOptions object and assign it to the 'Layout' property of the uibutton. Then inside the call for matlab.ui.layout.GridLayoutOptions, I just use name value arguments to assign the 'Row' and 'Column' property to match your original code. GridLayoutOptions objects are normally places indes the 'Layout' property of these types of objects, so this should work fine.

`GridLayoutOptions` is a specific subclass of `LayoutOptions` that applies to grid layouts, so you can create an instance of `GridLayoutOptions` as follows:

% Create a grid layout and a button 
uif = uifigure; 
uig = uigridlayout(uif); 
uib = uibutton(uig, 'Text', 'I want to be placed in one line'); 
% Create and set GridLayoutOptions properties 
glo = matlab.ui.layout.GridLayoutOptions; 
% Set row span width 
glo.RowSpan = [1 1]; % default 
% Set column span width 
glo.ColumnSpan = [1 5]; 
% Assign GridLayoutOptions object to button 
uib.Layout.Row = 2; 
uib.Layout.Column = 1; 
uib.Layout.GridLayoutOptions = glo; 

Here, `glo` is a `GridLayoutOptions` object that specifies the row span and column span of the button, and is assigned to the `GridLayoutOptions` property of the button's layout. You could modify the `RowSpan` and `ColumnSpan` properties of `glo` to suit your layout needs.

Alternatively, you could use the `LayoutOptions` object directly without creating a `GridLayoutOptions` object, as follows:

uib.Layout.Row = 2; 
uib.Layout.Column = 1; 
uib.Layout.RowSpan = [1 1]; 
uib.Layout.ColumnSpan = [1 5];

Here, the `RowSpan` and `ColumnSpan` properties of `LayoutOptions` are set directly.

Refer to the following resources

Create grid layout manager - MATLAB uigridlayout (mathworks.com)

I hope this helps you customize the layout options of your app! Let me know if you have any further questions.

From your answer I understand there is no way to place an object in a uigridlayout in one line, right?

This is a similar question, but I'm trying to create a 2048 game in the GUI app designer, but I can't seem to figure out how to access a GridLayout component by its handle or name. I have label components in a 4x4 gridlayout and want to change the text in the label from 0 to 2 or 4 randomly. How would i make a for loop that goes through every element in the 4x4 grid and randomly generate a 2 or 4?

Perhaps this will get you started (adapted from David's answer above). Although this doesn't use app designer.

uif = uifigure;
uig = uigridlayout('Parent', uif, ...
                   'ColumnWidth', repmat({'1x'}, 1, 4), ...
                   'RowHeight', repmat({'1x'}, 1, 4));
values = randi(2,1,16) * 2;
for i = 1:numel(values)
    [row, col] = ind2sub([4 4], i);
    uib = uilabel('Parent', uig, ...
                   'Text', num2str(values(i)), 'Layout', ...
                   matlab.ui.layout.GridLayoutOptions('Row', row, 'Column' , col), ...
                   'HorizontalAlignment', 'center');
end
