Description makosol 2019-11-02 11:03:39 UTC
When using a left vertical panel, when entering "modification mode" for the panel, it is not possible to reach the task manager widget options before it disappears when moving the mouse cursor towards it.

1. Configure a left vertical panel containing a task manager
2. Click the configuration button on this panel
3. Move the mouse cursor towards the task manager in order to make the options menu appear
4. Move the mouse cursor towards the options menu : it disappears immediately without being able to use it.
Some times it doesn't disappears but more often than not it does.

the option menu disappears

the option menu doesn't disappears

Make panel edit mode tooltip not unexpectedly disappear under certain circumstances

The panel edit mode tooltip can currently disappear in an irritating manner under two circumstances:
- You need to mouse the mouse diagonally out of the configuration areat to reach the tooltop, because the timer's duration is very short
- You move the mouse between the tooltip and the configuration area in preparation for moving it to another applet, because the timer did not stop when moving from the tooltip to the configuration area

This patch fixes both issues by increasing the timer duration and stopping the timer when entering the configuration area
FIXED-IN: 5.18.4

Test Plan:
Edit the panel
Hover over an applet and move the mouse diagonally to its tooltip, crossing empty space
Hover over an applet and move the mouse back to the configuration area, then back to the applet, and back to the configuration area, then to another applet, then to that applet's tooltip

In both cases, the tooltip remains visible, as expected.

Aargh! Based on your video it's at least better than it was before... :/
Comment 8 Nate Graham 2021-03-12 23:49:41 UTC
This has gotten worse lately. It's become utterly infuriating.
Comment 9 Nate Graham 2021-03-15 20:17:36 UTC
The bug is trivially 100% reproducible with the System Tray applet for me.

Some print statement debugging shows that sometimes the currentApplet variable doesn't get set when the cursor moved from one applet to another, which messes up the timers and causes the bug. So the last change I made for this wasn't wrong, but didn't address the root cause.
Comment 10 Nate Graham 2021-03-15 20:21:26 UTC
I think I found the problem: when the cursor passes over the panel's margins on its way to the pop-up, currentApplet gets reset to null, which triggers logic to start hiding the popup and disabled the mousearea in the popup that keeps it open when the cursor is over it.

You can kinda sorta fix this by not disabling the mousearea when currentApplet is null, but then the buttons don't work because they can't target the applet properly.

It seems like we need to not unset currentApplet so aggressively.
