How do you set the Layout Option at construction for ui objects?

If I have a simple uifigure like:

fh = uifigure;

gl = uigridlayout(fh);

I can add a uicomponent (and specify where on the gridlayout it will sit) like:

btn = uibutton(gl, Text="Hello World");

btn.Layout.Row = 2;

btn.Layout.Column = 2;

Is it possible to set the layout options using the Layout property of the btn e.g.

btn = uibutton(gl, Text="Hello World", Layout=???);

Sending a struct like:

btn = uibutton(gl, Text="Hello World", Layout=struct('Row',2,'Column',2);

Gives the error:

Error setting property 'Layout' of class 'Button':

'Layout' value must be specified as a

matlab.ui.layout.LayoutOptions object.

But I can't seem to instantiate an instance of the class LayoutOptions as:

l = LayoutOption();

Gives the error:

Unrecognized function or variable 'LayoutOption'.

Hi Rohan,

By using uilayout.GridLayoutOptions to create a LayoutOptions object, you can set the row and column properties before assigning it to the button's Layout property. Here's the corrected approach to set layout options for a button in a grid layout:

fh = uifigure;

gl = uigridlayout(fh);

% Create a LayoutOptions object

layoutOptions = uilayout.GridLayoutOptions;

layoutOptions.Row = 2; layoutOptions.Column = 2;

% Add a button with specified layout options

btn = uibutton(gl, 'Text', 'Hello World', 'Layout', layoutOptions);

Hope this answers your question.
