RESIZABLE attribute

(Graphical interfaces only)
Indicates if the user can resize a widget at run time.
Data type: LOGICAL
Access: Readable/Writeable
Applies to: BROWSE widget (browse and column), BUTTON widget, COMBO-BOX widget, EDITOR widget, FILL-IN widget, FRAME widget, IMAGE widget, LITERAL widget, RADIO-SET widget, RECTANGLE widget, SELECTION-LIST widget, SLIDER widget, TEXT widget, TOGGLE-BOX widget
If you set RESIZABLE to TRUE, the user can resize the widget. For the RESIZABLE attribute to take effect, you must also set the SELECTABLE attribute to TRUE.
Note: Setting the RESIZABLE attribute to TRUE enables direct manipulation events for the widget. These events take precedence over all other events. This effectively prevents data entry using the widget until all direct manipulation events are disabled (that is, until MOVABLE, RESIZABLE, and SELECTABLE are all FALSE).
