Description Kishore Gopalakrishnan 2022-06-05 06:44:32 UTC

SUMMARY
Usually while adding widgets to a panel, if you hover over an existing plasmoid, it will move to the left/right allowing you to add the new plasmoid in the desired position. However, the 'application launcher' plasmoid (the K menu) just activates itself instead of moving out of the way when the user hovers on it.

STEPS TO REPRODUCE
1. Have a panel with an 'application launcher' plasmoid
2. Right-click on the panel > Add widgets
3. Drag any widget from the sidebar that appears, and without releasing the mouse button, hold it on top of the application launcher

OBSERVED RESULTS
The application launcher menu is opened

EXPECTED RESULTS
The application launcher plasmoid should move out of the way, allowing the user to add the new widget to its left/right (just like the other plasmoids behave)

ADDITIONAL INFORMATION
Plasmoids which exhibit this buggy behaviour:
- Application launcher
- Activities (the one that opens the sidebar)
- Virtual desktop pager

Comment 1 Kishore Gopalakrishnan 2022-06-19 05:14:04 UTC

Should I file separate bugs for the activities button and the application launcher (since the component has been changed to 'pager')?

Comment 2 Nate Graham 2022-06-21 16:05:32 UTC

Oops, I missed "Panel"  and clicked on "Pager".

Cannot reproduce in the final 5.25 release. Can you?

I still cannot. Can you attach a screen recording that shows the issue? That might be illuminating.

Comment 6 Nate Graham 2022-07-05 14:12:11 UTC

Thanks for the video, that's helpful. I was under the mistaken impression that you were in Edit Mode, because I was thinking of a different bug that involved this happening while in Edit Mode.

I can reproduce the issue, but only with Kickoff. Moving to Kickoff since it seems like the issue happens there.

Comment 7 Nate Graham 2023-12-08 22:58:27 UTC

Can still reproduce in Plasma 6.

kickoff: fix external drag and drop, avoid conflicts with plasmoid dragging

Dragging a file or folder into kickoff's favorites view now adds the file/folder
to favorites. Kickoff now only takes drag events with the text/uri-list mimetype.
It should be noted that dragging task manager icons into kickoff will not work
because the task manager doesn't use text/uri-list.
