Can't close dropdown list when clicking on TabPage background

What do you want to achieve?

Hi! I have a dropdown inside a TabPage, when I open the dropdown I can’t close it when clicking on the TabPage background.
But if I do the same test using a Panel as a background, the dropdown closes successfully.

What have you tried so far?

I tried to change different flags on the TabPage but nothing works. The only workaround I have found is to add a Panel inside the TabPage and put the dropdown inside that panel.

Without Panel:

With Panel:


  • SquareLine Studio version: v1.3.4
  • Operating system: Windows 11
  • Target hardware: ESP32

I could reproduce the issue. It seems to happen even if the dropdown is not inside the tabpage in hierarchy, just appearing in front of it. Clicking on the tabpage behind doesn’t close the dropdown. It must be an LVGL ‘specialty’, and seems to occur in all supported LVGL versions even in exported/built code. Your panel workaround is a good solution, thanks for sharing that.
