Description Victor Pavan 2022-04-27 21:17:00 UTC

SUMMARY

When filtering only minimized windows, if there is no minimized window, the applet occupies the size of a icon, leaving a blank space (tested with both latte and plasma panel)

STEPS TO REPRODUCE
1.  Set to show only minimized windows
2.  Leave no windows maximized

OBSERVED RESULT

The applet leaves a blank space on the panel.

EXPECTED RESULT

The adjacent applets should come close together, reducing the overall occupied space.

applets/taskmanager: when empty, make width/height small but not zero

This makes the panel account for the change in size so that its minimum width or
height isn't too big.

Git commit 142ee9707de724e7a035e4c962b10e5ef6db6524 by Fushan Wen.

applets/taskmanager: set width/height to 0 when there is no task

The panel code should allow zero size in `Layout.preferredWidth` and
`Layout.preferredHeight`, so the task manager can shrink its size to
zero.
