Redraw problems after removing frame - revisited - issue just on macOS

Hello,

This is a follow up on

Redraw problems after removing frame

Hello, I need to dynamically add and remove frames (in the attached example just labels) from a GUI window based on a combo box entry. However, when I remove the frames and add new ones, the part of the old content is still drawn in the mother frame. Exists there any method to refresh the window? I tried gClient->Redraw(), but this didn’t work. Attached is a small example. Click on the combo box at an entry smaller than ten, then the lower limit of the group frame still displays old content…

Attached is the example “Problem.C” which works on Ubuntu 24.04.

Problem.C (2.9 KB)

Clicking on Entries, e.g. 5, removes some of the labels.

On Ubuntu 24.04 - and all previous versions - this works OK. See screenshot “WorksOnUbuntu.C”.

However, on macOS, here Sonoma 14.7, the old labels are not removed correctly.

Any tips on how to fix that on macOS?

Thanks,
Andreas

The GUI on MacOS is problematic, somehow… But maybe @Timur_Pocheptsov can take a look nevertheless?
