To enable runtime user movement and resizing of controls on a form with a mouse, three need special handling: OnMouseDown, OnMouseMove, and OnMouseUp.In theory, let's say you want to enable a user to move (and resize) a button control, with a mouse, at run-time. Firstly, you handle the OnMouseDown event to enable the user to 'grab' the button. Next, the OnMouseMove event should reposition (move, drag) the button. Finally, OnMouseUp should finish the move operation. Dragging and Resizing Form Controls in PracticeFirstly, drop several controls on a form.

Any one have any idea on how to select an area of text in a TEdit and have the cursor at the beginning of the selection.eg:TEdit.Text:= 'Delphi Rules';TEdit.SelStart:= 7;TEdit.SelLength:= 5;TEdit should now display 'Delphi Rules' with the last word selected (or something close to that) and the cursor at the end of the text. But I need the cursor at the beginning of the selection, just before the letter 'R'.Any ideas?Grant RE: Changing Cursor Position in TEdit (Programmer) 9 Feb 06 10:30.
