@class wxTipProvider
|
|
|
|
This is the class used together with wxShowTip() function.
|
|
It must implement wxTipProvider::GetTip function and return the
|
|
current tip from it (different tip each time it is called).
|
|
|
|
You will never use this class yourself, but you need it to show startup tips
|
|
with wxShowTip. Also, if you want to get the tips text from elsewhere than a
|
|
simple text file, you will want to derive a new class from wxTipProvider and
|
|
use it instead of the one returned by wxCreateFileTipProvider().
