Hi,
The areas we have needed to disable lightweight popups have been for
menus, tool tips, and combo boxes. The following details how to force
Heavy/Medium weight popups for these components:
To disable lightweight popups for a combobox do:
combobox.setLightWeightPopupEnabled(false);
for each combobox which may have a popup that overlaps a heavyweight.
To disable lightweight popups for tool tips do:
ToolTipManager ttm = ToolTipManager.sharedInstance();
ttm.setLightWeightPopupEnabled(false);
(Note that the javadoc says this method is deprecated but its documented
replacement does not exist so I can only assume the javadoc is in
error).
And to disable lightweight popups for all popup menus:
JPopupMenu.setDefaultLightWeightPopupEnabled(false);
This call must occur before the relevant menus are created as it has no
effect on existing menus.
Note that there is a bug with cascading medium weight popups which
should be fixed in the next release. See
http://developer.java.sun.com/developer/bugParade/bugs/4188832.html for
details.
Now if only there was some way of getting multiple JInternalFrames to
coexist happily with heavyweight components without strange rendering
artifacts I would be estatic. The other small issue we have is dragging
the JSplitPane separator over a heavyweight but it is not as annoying as
the JinternalFrame problem.
