Disabling item in Combox

[rcmaehl]

Hi all,

While I do see search results for this question, most are several years old. I'm hoping there's a UDF or other new change that will allow this since it appears to be possible in other languages. I'm not seeing anything in the help file but maybe there's something I'm missing somewhere 🤞?

Anyway, is there a way to disable selection of an item in a ComboBox now?

Thanks in advance!

Depends on what you mean by disable a selection within a combo box, just change the event for that selection, for example:

expandcollapse popup

#include <GUIConstantsEx.au3>
#include <MsgBoxConstants.au3>

Example()

Func Example()
    ; Create a GUI with various controls.
    Local $hGUI = GUICreate("Example", 300, 200)

    ; Create a combobox control.
    Local $idComboBox = GUICtrlCreateCombo("Item 1", 10, 10, 185, 20)
    Local $idButton_Close = GUICtrlCreateButton("Close", 210, 170, 85, 25)

    ; Add additional items to the combobox.
    GUICtrlSetData($idComboBox, "Item 2|Item 3|Item 4", "Item 1")

    ; Display the GUI.
    GUISetState(@SW_SHOW, $hGUI)

    Local $sComboRead = ""

    ; Loop until the user exits.
    While 1
        Switch GUIGetMsg()
            Case $GUI_EVENT_CLOSE, $idButton_Close
                ExitLoop
            Case $idComboBox
                $sComboRead = GUICtrlRead($idComboBox)
                ;~ Item 3 does nothing
                If GUICtrlRead($idComboBox) = "Item 3" Then ContinueLoop
                If GUICtrlRead($idComboBox) = "Item 4" Then
                    MsgBox(4096, "", "Item 4 is disabled")
                    GUICtrlSetData($idComboBox, "Item 1")
                    ContinueLoop
                EndIf
                MsgBox($MB_SYSTEMMODAL, "", "The combobox is currently displaying: " & $sComboRead, 0, $hGUI)
        EndSwitch
    WEnd

    ; Delete the previous GUI and all controls.
    GUIDelete($hGUI)
EndFunc   ;==>Example

That's one way to do it. It'd be nice to gray out the item too but I can indicate that another way using _GUICtrlComboBoxEx_SetItemImage

Perhaps:  GuictrlSetState($hCombo, $GUI_DISABLE)

This would disable the whole combobox, rather than just one item in it.
