Delphi Caret Position Tedit
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. You're welcome.I noticed that the functionality you desired could be achieved by clicking to the right of the last character in the edit box, then whilst pressing the Shift key, the left arrow key could be pressed as many times as required. After every character is selected in this way, the caret (or cursor) appears to the left of the selected character rather than to the right.I never actually explained what the code does, so if you haven't already worked it out here's what it's doing:Edit1.SelStart:= Length(Edit1.Text);Move the caret/cursor to the end of the text in Edit1for i:= 1 to 5 doPostKeyEx32(VKLEFT, ssShift, True);Simulate a key-press 5 times using a loopClive'To err is human, but to really foul things up you need a computer.'
