Implements

ControlFocusChange(ControlFocusChangeEvent)
Remarks
If ControlFocusChange() is used to validate a control (and also set the focus to another control), Control:SetFocus() should not be called until another control has received the focus. In complex dialog windows that contain many edit controls, it makes sense to grab the edit control's text when the focus is changing so that other controls can be updated with it if necessary. See the ButtonClick() method for an example of similar syntax to be used in this method. Note that all controls are passed through this method, not only SingleLineEdit and MultiLineEdit controls. If looking to control Combobox selections, then the ListBoxSelect() callback method should be reviewed.
