Grid Layout and Tab Group

I recently upgraded to r2019a, and I'm wondering if anybody experienced the same issue with the new feature Grid Layout in app designer.

I'm trying to fit a tab group in a certain region

but when I run the app this is what I get

The tab group won't keep the position.

Any solution?

thanks

Unfortunately, this is a regression in R2019a.

The workaround is to temporarily place the tab group in a different cell, then call drawnow, then place it back to its real location.

Example (outside AppDesigner):

f = uifigure;
g = uigridlayout(f);
c = uibutton(g);
tg = uitabgroup(g);

% Workaround:
%
% set it temporarily in a different location
tg.Layout.Row = 2;
% call drawnow
drawnow;
% set it back to its real location
tg.Layout.Row = 1;

Example (in AppDesigner):

% 1. Drag a tab group in a cell, e.g. row 3, column 1

% 2. Create a startup function and place the workaround in it, e.g.
% 
% set it temporarily in a different location
app.TabGroup.Layout.Row = 4;
% call drawnow
drawnow;
% set it back to its real location
app.TabGroup.Layout.Row = 3;

Note:

The temporarily location MUST be different from its actual location.

To make sure that is the case, you can set the temporary location to a cell 'outside' the grid, for example, if the grid is of size 5x5, set the temporary Row to 6.

Another way is to add 1 to the row (or column), then place it back.
