Combo Box List 30 Items

4 posts in this topic

Hi,

I have a combo box with about 60 items in it, it displays 30 items when you initially click on it, then the rest of the items appear when you scroll down. Is there a way to display only 20 items on the initial click as I'd prefer the combo box's list not to be longer than the hight of the forms window - purely for cosmetic reasons.

Thanks

am632,

You need to send the $CB_SETMINVISIBLE message to the combo: ;)

#include <GUIConstantsEx.au3>
#include <ComboConstants.au3>

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

; Create combo empty
$cmbBranch = GUICtrlCreateCombo("", 170, 40, 160, 25)
; Now add data
$sData = ""
For $i = 1 To 60
    $sData &= "|" & "Item " & $i
Next
GUICtrlSetData(-1, $sData)
; And now limit the number of items to show to 20
GUICtrlSendMsg($cmbBranch, $CB_SETMINVISIBLE, 20, 0)

GUISetState()

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

Note that $CB_SETMINVISIBLE actually sets the MAX visible - but please blame Bill Gates, not me! :D

There is one more include needed:

#include <ComboConstants.au3>

AutoBert,

Quite correct - thanks for picking it up. :)

There is an additional section in the script from which I extracted that snippet which uses GUIComboBox.au3 and so automatically included the required constants. I took out the GUICtrlComboBox* functions and also the #include and did not run the script again before posting. :>
