I would like to place a cursor in a XmText widget when it loses focus so that the user know where, in the text widget, he/she was when it was last used. Is there any quick and painless way of doing this? Thanks for any info anyone can give me. Rich --- I bet you were expecting a disclaimer here, weren't you?

It is called the destination cursor and is displayed as a caret "^". It marks the position of the destination selection. When the destination is at the same position of the insert cursor and the widget has the focus, only the blinking I-beam is visible. When the widget loses focus, the caret cursor remains at the insertion point. This cursor has many purposes, but is mainly used with keyboard selections. This was not trivial to do and I would not recommend trying to add your own cursor. There is alot of overhead associated with the destination cursor, and it still needs some performance tuning. If you do decide to add a cursor, you would have to get into the guts of the text widget to understand how cursor manipulation is being done. The text widget does some XCopyAreas() and XClearAreas() that could occlude your cursor drawing. Also, you would need to be notified if you started typing elsewhere to delete your cursor. You could use selections to do this. It would not be quick or painless. Joe Whitty
