Description Anthony Fieroni 2015-10-31 19:39:29 UTC
Click on item in systray item random highlight on other.

Reproducible: Always

Steps to Reproduce:
1. Left click on item in system tray
2. Expand view is opened
3. Perform right or left mouse move, do not perform click
4. Move mouse out from systray, last pointed item stays highlighted

Actual Results:  
When mouse pointer goes out of systray last pointed item stays highlighted.

Expected Results:  
When mouse goes away last pointed item must NOT be highlighted.

Same issue as https://bugs.kde.org/show_bug.cgi?id=353752
This concerns for whole panel and whatever have pointed items. I don't know it's QtQuick issue, but it's ridiculous.

Any progress here? This bug is not a big deal, but it's irritant. Did you want any help?
Comment 2 David Edmundson 2015-11-15 12:34:39 UTC

Mone more http://tinypic.com/player.php?v=110ho4z%3E&s=9 last click is affected, when click and move away information tip stays because item (clipboard) is highlighted.
As you can see http://tinypic.com/player.php?v=33jjsls%3E&s=9 when click menu and move away dolphin icon stays highlighted till i return to panel. It'a big focus bug all over Qt5 - i think

Comment 7 Anthony Fieroni 2015-11-26 06:01:47 UTC
Add revew request with working patch
Comment 8 David Edmundson 2015-11-26 21:00:14 UTC
Seems like you're right about the cause

So that bit of code solves the following problem:
 - applets aren't flush to the edge of the screen, in order to have a visual margin the applets have some padding
 - clicking on the edge of the screen are easiest to hit with the mouse and we want clicking on their to activate the applet
The code you've linked to found copies mouse events in the panel into the relevant applet.

Now it seems that's not very good as we send a mouse press event into some applet/button, but that doesn't get a mouse-leave, as the mouse was never in there to begin with.

Either we track that inside the panel (there's similar code in dialog) and proxy mouseleaves (which will have to be very clever) or we find another solution to the above problem.
Comment 9 David Edmundson 2015-11-26 22:58:44 UTC
/maybe/ if we just add MouseEnter and MouseLeave to the swtich statement it'd just work?

 might mean the containment gets a double and and leave. Worth a shot?

revision 31b0bf7f "Prevent possible endless recursion in PanelView event handling"
sendEvent is replaced with postEvent. If you mean to add QEvent::Leave to switch statement it's not work.
Comment 11 Anthony Fieroni 2015-11-27 04:04:59 UTC
Maybe it better to not post MouseMove, ony click action, what you think?

This fix/patch causes mouse clicks to fail 2 out of 3 times on clicking any icon on the panel.  Plasma-workspace 5.5.0 build from tars available to packagers yesterday.
Reverting the patch, all left click mouse actions work again on first click.
Comment 14 Anthony Fieroni 2015-12-08 03:54:01 UTC
The patch is correct! The problem is on X, on Wayland works as expected, but Wayland is still a preview. I wrote in review request https://git.reviewboard.kde.org/r/126175/ after MouseButtonPress Leave is triggered only on X, this is a huge bug on K Windowed system/KWin or Qt on xcb - i don't know, Marting Graesslin knows better.
Comment 15 Anthony Fieroni 2015-12-13 12:37:18 UTC
I reopen, cause patch has a regression on Xcb, on Wayland works as expected. I made new review request https://git.reviewboard.kde.org/r/126331/ it's need more tests here, we don't want any regression.
