So I have this edit control that contains some default text.

Code:

Gui, Add, Edit, r3 vEditText y+10 w140, Add some extra notes.

What I would like to do is when someone clicks in the edit control the default text is cleared. I could not find a built in option in the help system.

This GUI I am creating will eventually take the input from all controls and put them in the clipboard to be pasted in helpdesk tickets. I don't want the "add some extra notes" in every ticket.

Any ideas?

You can use OnMessage to catch clicks in the Edit control:

Code:

Gui, Add, Edit, r3 vEditText HwndEdit y+10 w140, Add some extra notes.
Gui, Show
OnMessage(0x201, "WM_LBUTTONDOWN")
Return

WM_LBUTTONDOWN(wParam, lParam, Msg, hWnd)
{
   Global Edit
   If (hWnd = Edit)
      GuiControl,, Edit1
}

Serenity I tried you suggestion and it clears the edit field but for some reason no matter what contol I click on it minimizes or hides the GUI.

I really don't understand the WM_LButtonDown parameters. This is the first time I have every used this type of code. From what I can see the hWnd is passed and it compares it to Edit. But for some reason it is making the comparison no matter what GUI control I click on.

Code:

WM_LBUTTONDOWN(wParam, lParam, Msg, hWnd)
{
   Global Edit
   Edit
   If (hWnd = Edit)
   {
      GuiControl,,Edit1
   }
}

SKAN thanks for the link. The Timer approach worked perfectly.
