Really basic query - can't believe I'm asking this, but can't work out how to do it with blitzplus gui:

How do I detect an "ENTER" or "RETURN" key pressed while in a text field. I've tried using event $401, $103 even a HotKeyEvent but cannot seem to detect the pressing of the enter key:

window = CreateWindow("Simple Entry Screen",GadgetWidth(Desktop())/4,GadgetHeight(Desktop())/4,400,400)

fntArial36 = LoadFont("Arial",36)

lbl1 = CreateLabel("ID Number",90,75,200,40,window)
SetGadgetFont lbl1,fntArial36

txtinput = CreateTextField (90,120,200,40,window)
SetGadgetFont txtinput,fntArial36

timer=CreateTimer(0.33)

ActivateGadget txtinput
HotKeyEvent 28,0,$4001

Repeat

WaitEvent()

Select EventID()

;case $103 ; case $401 ; what do I use to detect an ENTER or RETURN while in txtinput??

		
Case $4001
	;collect user id if text field non blank

Case $803
	If Confirm ("Quit:Are You Sure?") Then End 



End Select


Forever

Thanks for any assistance.

Thanks for the assistance, I've posted the relevant code here (that you posted in the other thread) as well in case anyone is after the same thing. I must say though - it is a bizarre fix.

W = CreateWindow("Blub",100,100,200,200,Desktop(),1)
T = CreateTextField(10,40,70,20,W)
B = CreateButton("OK",100,40,40,20,W,4) ; You can hide this or set 0 for width and height if you don't want it to be seen.

Repeat
  Select WaitEvent()
    Case $803 End
    Case $401
      If EventSource() = B Then Notify "you pressed Return in the textfield!"+Chr(13)+"Or you clicked the Button..."+Chr(13)+"Your Text: "+TextFieldText(T)
  End Select
Forever

erm just in case you didn't know event $4001 is a timer tick event
you'd better use a custom thin like $3012 or whatever

Hi Stamm, I realise event $4001 is a timer tick event - I use it to check and clear the contents of the text field every 'n' seconds - useful for what we do at work
