I hope I will have soon found out and corrected all the small issues

that make the edit control act not perfectly perfect.

 

When you open a file in read-only mode (e.g. in sample MDITextEditor open it and select option "Read Only" from menu),

then all actions to modify the document from the context menu

and main "Edit" menue are still ENABLED (e.g. "Paste", "Cut", "Tabify Selection", "Delete").

 

This itself is only a small issue.

But it becomes really annoying, that when you select e.g. "Paste" or

"Tabify selection", then the document is marked as modified via

"SetDocModified" (called from inside the XTSyntaxEdit control element).

Which in turn means, when you are asked to save, if you close the

document (and that for a read-only document which you most probably

never want to save !)

 

In my mind the easiest way to correct the problem would be

to correct the Update-UI-Handler for ID

ID_EDIT_UNDO,
ID_EDIT_REDO,
ID_EDIT_CUT,
ID_EDIT_PASTE,
ID_EDIT_CLEAR,
ID_EDIT_REPLACE,

in "CXTPSyntaxEditView"
