Dear all,
Thanks for your reviews and Seigo's encouragements!
According to your discussion, I make another two patches based on Seigo's
patch.
1 kdelibs-palsma-tooltip-previewclick-aseigo-modified.patch
It should apply to the directory kdelibs/plasma/
2 kdebase-workspace-plasma-tasks-previewclick-aseigo-modified.patch
It should apply to the directory kdebase/workspace/plasma/applets/tasks/
Best regards
pwp
