MATLAB: UITable does not resize with rest of figure window

MATLAB

I have created the following uitable,

f = figure;

uitable(f, 'Data', rand(30,30));

When I resize the figure as a whole by clicking and dragging on the corner, the table does not get resized with the rest of the window.

For any figure component to automatically resize, you must change its "Units" property to "normalized."

The default position units are in "pixels" which obviously don't scale with the figure itself. Once you have change "Units" to "normalized, you can reset the "Position" property as appropriate.

MATLAB: Does overlapping panels in GUIDE seem to lock their ‘visible’ property in MATLAB 7.9 (R2009b)

GUIDE will make any UI component, which is positioned within or over a panel, a child of that panel. This includes other panels.

Thus, the above behavior is expected because, when a panel's visibility is set to 'off', any components that are a child of that panel should also not be visible.

The solution is to make sure that your panels are all direct children of the figure window, rather than nested within each other. You can do this with additional code in the Opening Function. For example, you could add similar code to this:

% Ensure uipanels are parented by the figure
panel_handles = findobj(handles.figure1,'type','uipanel')
set( panel_handles, 'parent', handles.figure1)

MATLAB: Uicontrols do not resize with figure window in the app

A UIPanel or TabGroup will only resize if the components within that panel or tab group resize and thus force the panel or tab group to expand. For example, if you place an Axes inside a UIPanel, the axes will re-scale as the figure window is expanded, so the panel will expand too. However, if you place only a pushbutton inside the panel, no resizing will occur, since uicontrols do not automatically resize. Thus, the real issue here is that your uicontrols are not resizing.

To make your panels with uicontrols scale better, try the following:

1) Change the position "units" of each uicontrol to "normalized". For example,

f = uifigure;

pb = uicontrol('Style','pushbutton','String','Push Me');

pb.Units = "normalized";

A pushbutton will now scale properly when shrinking/expanding the figure window.

2) Simply make the figure larger in the Design View of App Designer by clicking and dragging on the lower right corner of the window canvas. Then resize the rest of the components appropriately (before running the app).

3) Make the figure appear the same relative size across computer screens with different resolution / dimensions. In a normal figures, this can be achieved with "normalized" units. However, a uifigure is currently limited to units of "pixels", which means that the figure window will have a different relative size on, say, a large 4k monitor than a small laptop. To imitate the behavior of "normalized" units, follow the method outlined in the MATLAB Answers post below:

If the figure window has the same relative size across different machines, there should be little need to resize the window in the first place.
