Version: (using KDE 4.0.0) Installed from: SuSE RPMs I open the dialog "Add Widgets" from upper right corner of the screen and hold the left mouse button pressed. http://techbase.kde.org/Projects/Plasma/FAQ#How_can_I_add_applets_to_the_panel.3F It happens that widgets will put on my desktop before I move the mouse (performing the drag). How will it be achieved that objects will only be placed on the panel after dragging was finished (by releasing the mouse button)?
this works fine here; you need to actually place it on the panel properly though. this is much easier with the code in trunk/ than in the 4.0 branch unfortunately. and of course, it won't be the only way to add widgets to the panel in 4.1. it's a bit too clumsy for my liking even when it works perfectly.
I have not got a problem with the panel as drop target. I have got the impression that there is an open issue with event processing at the drag source. How big is the probability that a pressed mouse button is interpreted as a full or double click?
just to be absolutely sure: you're dragging the widget's entry in the list, right? you're not going anywhere near the 'add widget' button? a pressed mouse button should never be interpreted as a click here, let alone a doubleclick. have you ever had trouble with drag&drop in other programs?
I pick an item from the widget list box. I don't press the button "Add widget" in the dialogue. I can not tell you about further click troubles in other KDE 4 programs so far.
still can't reproduce...
