DesktopUIControl.FocusLost
From Xojo Documentation
Event
The control has lost the focus.
Notes
If the control has an AllowFocus property, then it must be set to True for the control to be capable of getting then losing the focus, e.g. DesktopBevelButton.
On macOS, controls other than text fields and lists will accept and lose focus only if the full keyboard access option is enabled in System Preferences/Keyboard. |
