Read-Only

Buttons, check boxes and various other widgets can be made read-only or read and writeable.

Read-only mode does not allow the user to change anything about the widget, whilst read and writeable will allow the user to change, select or edit the widget.

Read-only can be enabled or disabled by using DDgui_set with the “READONLY” parameter. 

An example for this would be :

DDgui_button("t1","moo",100,50)

DDgui_button("t2","moo",100,50)

DDgui_set("t1","READONLY",TRUE)

Which makes the “t1” button read-only, which means that if the user moves the mouse over or presses the first button, nothing will happen.

A widget's colour wont change if the mouse is moved over a READ-ONLY widget.

To disable read-only mode, the “READONLY” parameter should be set to FALSE :

DDgui_set("t1","READONLY",FALSE)
