Position Cursor in Edit control?

Hi All,

How do I position the cursor within an edit control? I've tried
SetCursorPos and SetCaretPos and they seem to have no affect.

Thanks,
Steve

Try the SelStart property.

Edit.SelStart

Re:Position Cursor in Edit control?


I need to set the cursor to the end of the text or, if no text exists,
set it to the beginning ot the edit buffer. How is SelStart going to
help? In the OnEnter event of the control, I tried:

TEdit(Sender).SelStart := 0;

This had no affect on cursor position.

This does:

edit1.setfocus; //Needed if you are outside the edit
edit1.selstart:=0; //or whatever.

Problem/Question/Abstract: How to determine the caret position in a TMemo. Answer: You can use the Windows API messages EMLINEFROMCHAR and EMLINEINDEX to determine the current line and offset within that line (starting from SelStart). LineNum: longint.

  • For the caret build into standard edit controls (TEdit, TMemo in Delphi) or created by a call to the CreateCaret API function the Windows API has a function GetCaretPos, but the problem (for you) is that this function only returns the (last) position of a caret inside the application that calls it. You cannot get the position of the caret.

Problem/Question/Abstract:
Does anyone know how I might be able to suppress the text cursor in a TEdit, so it's not visible?
Answer:
For that you need to call the HideCaret API function after the control has processed the WM_SETFOCUS message. The OnEnter event is a tad too early for that, so if you do not want to create a TEdit descendent with an overriden message handler for WM_SETFOCUS you need to delay the action by posting a message to the form and have the handler for that message do the HideCaret.
The three edits on this example form share the same OnEnter handler (AllEditEnter), have ReadOnly = true and AutoSelect = false.

Of course this is an excellent way to confuse the user, since there will be no indication where the focus is anymore when the user tabs into one of the edits...
