ComboBox - function on Enter press


Recommended Posts

How to register a function when I enter text and press the Enter button?

I tried this Case $MyCombo in main GUI Loop. But it works even when I just select a new value from the list. And this is not necessary. Only on Enter in Combo field

mike2003,

I would see if the combo edit box has focus when Enter is pressed - like this:

#include <GUIConstantsEx.au3>
#include <WinAPISysWin.au3>
#include <GuiComboBox.au3>
#include <Misc.au3>

Global $tInfo

$hDLL = DllOpen("user32.dll")

$hGUI = GUICreate("Test", 500, 500)

$cCombo = GUICtrlCreateCombo("", 10, 10, 200, 20)
GUICtrlSetData($cCombo, "1|2|3")

GUISetState()

; Get handle of combo edit box
If _GUICtrlComboBox_GetComboBoxInfo($cCombo, $tInfo) Then
    $hComboEdit = DllStructGetData($tInfo, "hEdit")
Else
    ConsoleWrite("Fail" & @CRLF)
    Exit
EndIf


While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            DllClose($hDLL)
            Exit
    EndSwitch

    ; Check for Enter press
    If _IsPressed("0D", $hDLL) Then
        ; Check if combo edit box has focus
        If _WinAPI_GetFocus() = $hComboEdit Then
            ConsoleWrite(GUICtrlRead($cCombo) & @CRLF)
        EndIf
    EndIf
    ; Wait for Enter release - try without this to see why you need it! 
    While _IsPressed("0D", $hDLL)
        Sleep(250)
    WEnd

WEnd

Or a little different approach :

#include <GUIConstants.au3>
#include <GuiComboBox.au3>

Local $hGUI = GUICreate("Test")
Local $cCombo = GUICtrlCreateCombo("", 10, 10, 200, 20)
GUICtrlSetData($cCombo, "1|2|3")
GUICtrlCreateLabel ("Edit :", 10, 50,50,20)
Local $cEdit = GUICtrlCreateInput ("", 50, 50, 150, 20)

Local $cButton = GUICtrlCreateButton("OK", 10, 100, 100, 25)
Local $cDummy = GUICtrlCreateDummy()

Local $aAccelKeys[1][2] = [["{ENTER}", $cDummy]]
GUISetAccelerators($aAccelKeys)

GUISetState()

Local $tInfo
_GUICtrlComboBox_GetComboBoxInfo($cCombo, $tInfo)
Local $hCombo = DllStructGetData($tInfo, "hEdit")

While 1
  Switch GUIGetMsg()
    Case $GUI_EVENT_CLOSE, $cButton
      ExitLoop
    Case $cDummy
      If ControlGetHandle($hGUI, "", ControlGetFocus ($hGUI)) = $hCombo Then
        ; put your code here
        ConsoleWrite(GUICtrlRead($cCombo) & @CRLF)
      EndIf
  EndSwitch
WEnd

mike2003,

It sounds as if you are running an older AutoIt release - there was a major reorganising of the WinAPI UDFs by jpm for the last one. So you can probably manage with including just WinAPI.au3.
