GUI Object Base - Text Owner
|
|
|
|
--Overview--
|
|
|
|
Interface class that enhance the IGUIObject with
|
|
cached CGUIStrings. This class is not at all needed,
|
|
and many controls that will use CGUIStrings might
|
|
not use this, but does help for regular usage such
|
|
as a text-box, a button, a radio button etc.
|
|
|
|
