Here is a snippet of code:
::method initDialog
expose staticText
staticText = self~newStatic(IDC_ST_TYPE)
self~connectEditEvent(IDC_EDIT, GOTFOCUS, "onFocus")
self~connectEditEvent(IDC_EDIT, LOSTFOCUS, "onLostFocus")
::method onFocus unguarded
expose staticText
staticText~setText("The edit control now has the focus")
return 0
::method onLostFocus unguarded
expose staticText
staticText~setText("The edit control does not have the focus")
return 0
In the above dialog, I change the text of a static control to show
when the edit control gets the focus and when it losses the focus
A couple of points.
* You don't *have* to connect both the got focus and lose focus events
if you are only interested in the lost focus. You can just connect the
LOSTFOCUS event.
* Technically, the program probably did not need to return 0 from the
2 event handlers. But, it is a good habit to always return a value
from an event handler.
I'll write an example and add it to the Extra ooDialog Examples
package. What type of processing are you thinking of doing?
