Description MitraX 2022-10-25 12:48:22 UTC

SUMMARY

If a user opens too many applications with unchecked "Fill free space on panel" option of Icon-Only Task Manager with un-grouped items,  widgets on the right side are pushed out of display.


STEPS TO REPRODUCE

1. Open Icon-Only Task Manager settings
2. Deselect the option "Fill free space on panel" in the General tab
3. Choose option "Do not group" in the Behavior tab
3. Save changes
4. Open multiple applications one by one so their multiple icons are displayed un-grouped on the panel (e.g. multiple instances of Konsole)


OBSERVED RESULT

If there's too many application icons on the panel, widgets on the right (e.g. notifications, clock...) will be pushed out of screen while the size of the icons in icon-only task manager remains unchanged.


EXPECTED RESULT

The icons in icon-only task manager should be resized while widgets on the right side stay in place.

I guess without Layout.FillWidth set, there's effectively no width bound set, so the contents can overflow.

Basically we need this change:

diff --git applets/taskmanager/package/contents/ui/main.qml applets/taskmanager/package/contents/ui/main.qml
index 706ebe80d..0a48376b5 100644

     }
+    Layout.maximumWidth: tasks.vertical ? -1 : [the width it *would* consume if Layout.fillWidth were set]

 //BEGIN TODO: this is not precise enough: launchers are smaller than full tasks
     Layout.preferredWidth: {


But I can't figure out how to get those width and height values. Niccolò, any ideas?
