Description Carsten Reckord CLA 2015-01-21 14:29:48 EST 
On Linux/GTK, ToolTip is closed when the mouse cursor enters the ToolTip widget's shell. On other platforms (Windows 7/8, MacOS) it works fine. For some reason, there seems to be an additional MOUSE_EXIT event under GTK that triggers the TooltipHideListener.

This caused bug 423908 and bug 455262 in MPC for the two custom tooltips we are using there.

Moving to SWT for investigation

BTW this also causes the problem with Customize Perspective Dialog under Linux: the tooltips over the toolbar entries contain sometimes links which allow user to jump to the corresponding entry in the action set tab. On Linux, NO ONE can click on the link in the tooltip, because it disappears as soon as the mouse enters it.
I will make link to bug 420956.

Lars decoupled it again (which makes sense), but we should have a separate bug for the CPD, assuming the problem is still there.

I cannot reproduce this issue, non-native ToolTips seem to display just fine. IIRC there were some fixes for ToolTips in late 2015.

Please re-open this ticket if the issue continues to occur.
