Set position of combo box

[drw4281]

Hey guys,

So, I have a combo box with a list of items. I want the user to be able to select an item via the combo box like normal, but also be able to use PREV and NEXT buttons I have to walk up and down the list. I can't figure out how to set the selected item in a combo box though. Thanks.

Look at these functions in the helpfile

#Include <GuiComboBox.au3>

_GUICtrlComboBox_GetCurSel()
_GUICtrlComboBox_SetCurSel()

drw4281,

Do you mean like this:

expandcollapse popup

#include <GUIConstantsEx.au3>
#include <GuiComboBox.au3>
#include <Array.au3>

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

$hCombo = GUICtrlCreateCombo("", 10, 10, 200, 20)

$sData = ""
For $i = 1 To 20
    $sData &= "|" & "Item " & $i
Next
GUICtrlSetData($hCombo, $sData)

$hButton_Up = GUICtrlCreateButton("Up", 250, 10, 80, 30)
$hButton_Dn = GUICtrlCreateButton("Down", 250, 50, 80, 30)

GUISetState()

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $hButton_Up
            $sCurr = GUICtrlRead($hCombo)
            $aList = _GUICtrlComboBox_GetListArray($hCombo)
            $iIndex = _ArraySearch($aList, $sCurr)
            If $iIndex > 1 Then
                _GUICtrlComboBox_SetEditText($hCombo, $aList[$iIndex - 1])
            EndIf
        Case $hButton_Dn
            $sCurr = GUICtrlRead($hCombo)
            $aList = _GUICtrlComboBox_GetListArray($hCombo)
            $iIndex = _ArraySearch($aList, $sCurr)
            If $iIndex < $aList[0] Then
                _GUICtrlComboBox_SetEditText($hCombo, $aList[$iIndex + 1])
            EndIf
    EndSwitch

WEnd

Any use?

Or this one:

#include "ComboConstants.au3"
GUICreate("Test")
Global $nCombo = GUICtrlCreateCombo("", 10, 10, 100, 60, 0x3)
GUICtrlSetData(-1, "Item1|Item2|Item3|Item4", "Item1")
Global $nUP = GUICtrlCreateButton("t", 110, 9, 20, 12)
GUICtrlSetFont(-1, 10, 400, 0, "Marlett")
Global $nDOWN = GUICtrlCreateButton("u", 110, 20, 20, 12)
GUICtrlSetFont(-1, 10, 400, 0, "Marlett")
GUISetState()
Global $msg
Do
 $msg = GUIGetMsg()
 If $msg = $nUP Then GUICtrlSendMsg($nCombo, $CB_SETCURSEL, GUICtrlSendMsg($nCombo, $CB_GETCURSEL, 0, 0) + 1, 0)
 If $msg = $nDOWN Then GUICtrlSendMsg($nCombo, $CB_SETCURSEL, GUICtrlSendMsg($nCombo, $CB_GETCURSEL, 0, 0) - 1, 0)
Until $msg = -3

Case $hButton_Up
            $sCurr = GUICtrlRead($hCombo)
            $aList = _GUICtrlComboBox_GetListArray($hCombo)
            $iIndex = _ArraySearch($aList, $sCurr)
            If $iIndex > 1 Then
                _GUICtrlComboBox_SetEditText($hCombo, $aList[$iIndex - 1])
            EndIf
        Case $hButton_Dn
            $sCurr = GUICtrlRead($hCombo)
            $aList = _GUICtrlComboBox_GetListArray($hCombo)
            $iIndex = _ArraySearch($aList, $sCurr)
            If $iIndex < $aList[0] Then
                _GUICtrlComboBox_SetEditText($hCombo, $aList[$iIndex + 1])
            EndIf

Just simplified by my recomended way:

Case $hButton_Up
            $iIndex = _GUICtrlComboBox_GetCurSel($hCombo)
            _GUICtrlComboBox_SetCurSel($hCombo, $iIndex - 1)
Case $hButton_Dn
            $iIndex = _GUICtrlComboBox_GetCurSel($hCombo)
            _GUICtrlComboBox_SetCurSel($hCombo, $iIndex + 1)

Note: There is no error/bound checking

Awesome, thanks guys. Now to just decide which approach to use, haha.
