Dear all:
I have one quesiton:
If I want to keep the tool tip showing as long as the cursor is in the
component, can I do it in SWT?
In Swing, it is easy to do it:
Set ToolTipManager the Max number value.
But SWT doesn't support such method.
How to solve this problem?
I am looking forward to hearing from you.
Thx for any suggestion and help!
Have a nice day,
B.W
