Quotidian uses mouse double-clicking to open an editor on a list
field. Also, double-clicking on a panel's titlebar causes that panel to be
maximized or restored.
Double-clicking is not a function of the mouse, but is manufactured by
the system and application to combine successive mouse clicks into a
single event. The time between combined mouse clicks is set in the
operating system rather than in the QEditor. Setting the time too
small will make it difficult to start editors in lists.
In the Control Panel, click on "Hardware and Sound," click on "Mouse"
and change the double-click time. Note that Microsoft uses this time
for other things, so changing the value may also change the behavior
of tooltips, menus, scrollbars, incremental searching in list boxes,
and probably other things.
Open the "System Preferences" window, open the "Keyboard & Mouse," and
choose the "Mouse" tab. Change the "Double-Click" setting.
At the present time, Java is checking the XSettings for the
double-click value. It seems to ignore the Gnome or KDE settings for
this value. This may change in the future. A workaround is to add
to the file ~/.Xdefaults and run
xrdb -merge ~/.Xdefaults
This will increase the combining time from 0.2 seconds to 0.5 seconds.
