Hi,

I would like to use QTextEdit with drag-n-drop but with CUT-n-PASTE and not the default COPY-n-PASTE.

To do this I I subclassed QTextEdit and and re-implemented
Qt Code: 
  1. dragEnterEvent
To copy to clipboard, switch view to plain text mode 
and
Qt Code: 
  1. dropEvent(QDropEvent *event)
To copy to clipboard, switch view to plain text mode 
. However,. even though it now works with cut-n-paste the cursor is all screwed up.

I.e. the cursor position is where I SELECTED the text and not where I dropped the text. IF I change that (setPosition, setTextCursor etc) I still end up with the problem that if I click somewhere on the document the 'ACTUAL' cursor moves to where I click BUT it is invisible, the cursor symbol is where the cursor was BEFORE I clicked on the document....

I COULD probably fix it by re-implementing more mouse events (mousePress, etc) but I think it should be possible to solve much easier.

So my questions are
1) Best way of getting cut-n-paste instead of copy-n-paste for drag-n-drop of text in a QTextEdit?

2) If it IS by subclassing dragEnterEvent and dropEvent then how can I fix the cursor problem?

See my code below for how it is implemented now
Qt Code: 
  1. void TextEdit::dragEnterEvent(QDragEnterEvent *e)
  2. {
  3. 	e->acceptProposedAction();
  4. }
  5.  
  6.  
  7. void TextEdit::dropEvent(QDropEvent *event)
  8. {
  9.          event->acceptProposedAction();
  10.  
  11. 	if ( event->dropAction() == Qt::CopyAction)
  12. 	{
  13.  
  14.  
  15. 		QTextCursor cursor = textCursor();	// copy of cursor
  16.  
  17.                // Drop position cursor
  18. 		QTextCursor insertionCursor = cursorForPosition( event->pos() );  
  19.  
  20. 		insertionCursor.beginEditBlock(); /* Start atomic operation (undo/redo) */					
  21.  
  22. 		QTextDocumentFragment text = cursor.selection();  /* Extract text before removing selected area */
  23.  
  24. 		cursor.removeSelectedText();		 /* Remove from original position */	
  25. 		insertionCursor.insertFragment( text );	/* Insert dragged text/image/link */
  26.  
  27.                // Tried with set setTextCursor here but that only moved the visible cursor
  28.                // initially. Clicking on the document still gives an active invisible cursor
  29.                // AND a non-active visible cursor symbol
  30.  
  31.                insertionCursor.endEditBlock();	/* End atomic operation (undo/redo) */	
  32. 	}
  33. }
To copy to clipboard, switch view to plain text mode
