| When the Cursor is accessed using CURSORSETPROP(), the ReadOnly property is read-only at run time. |
The ReadOnly property differs from the Enabled property because when ReadOnly is set to true (.T.), the user can still move to the control.
For Cursors, ReadOnly mimics the NOUPDATE clause of USE.
For combo box controls, the ReadOnly property cannot be set to true (.T.) when the Style property is set to 2 – Drop-down List.
For a file in a project, the ReadOnly property contains a logical value that indicates if the file can be edited. If ReadOnly is true (.T.), the file can be edited; otherwise the file cannot be edited. Read-only at design time and run time.
