@class wxTipWindow
|
|
|
|
Shows simple text in a popup tip window on creation.
|
|
This is used by wxSimpleHelpProvider to show popup help.
|
|
The window automatically destroys itself when the user clicks on it or it
|
|
loses the focus.
|
|
|
|
You may also use this class to emulate the tooltips when you need finer
|
|
control over them than what the standard tooltips provide.

dismiss the tip mouse when the mouse leaves the object it is associated with.
