Two simple combo box questions

7 posts in this topic

I'm adding my first use of a combo box to a simple data entry GUI. I pasted in the example from the help file (GUICtrlCreateCombo) and changed it to show the four choices I want the user to have. That much works fine. But I can't figure out these two aspects:

How do I prevent the user from typing something in that is not one of my choices? IOW, I want the field to be "selectable", but not "editable".

How do I cause the field to deselect after the user clicks on it and makes a selection? Right now, it remains highlighted.

Thanks in advance for any help.

Use the style $CBS_DROPDOWNLIST.

As for your other question use the help file, there are plenty of examples e.g. look at the _GUICtrlComboBox_ functions.

Hi,

I want the field to be "selectable", but not "editable".

#include <ComboConstants.au3>

GUICtrlCreateCombo("", 0, 0, 100, 20, $CBS_DROPDOWNLIST)

How do I cause the field to deselect after the user clicks on it and makes a selection?

$coMyCombo = ...
GUIRegisterMsg($WM_COMMAND, "WM_COMMAND")

Func WM_COMMAND($hWnd, $iMsg, $iwParam, $ilParam)
Local $iIDFrom, $iCode

$iIDFrom = _WinAPI_LoWord($iwParam)
$iCode = _WinAPI_HiWord($iwParam)

Switch $iCode
Case $CBN_CLOSEUP
If $coMyCombo = $iIDFrom Then
;ACTIVATE ANOTHER CTRL by ControlFocus OR GUI by WinActivate HERE TO SET THE FOCUS ON SOMETHING ELSE.
EndIf
EndSwitch

Return $GUI_RUNDEFMSG
EndFunc   ;==>WM_COMMAND

Br, FireFox.

Thanks, FireFox. That works just as described. I was able to add another input field just below my ComboBox, with a ControlFocus in the script where you indicated.

But what if I don't want ANY field to have focus after the select? I couldn't find a ControlFocus=None ... and defining as "" didn't work.

Any suggestions?

You can set the focus on a hidden label for example.

Br, FireFox.

Actually (I've now found), the label doesn't have to be a hidden one. Changing focus to any label field deselects an input-type field.

I never thought of trying that ... because focus implies that it's input-related.

Thanks very much.

Yes, HIDDEN or not it does not change anything, I read your text too fast and I though you said "what if I don't *have* ANY *ctrl* to have focus after the select?"
