Horizontal Scroll Bar in Listbox

4 posts in this topic

Here is the code:

#include <GUIConstantsEx.au3>

Opt('MustDeclareVars', 1)

Example()

Func Example()
    Local $MESSAGE = "The following buttons have been clicked"
    Local $add, $clear, $mylist, $close, $msg
    
    GUICreate("My GUI list") ; will create a dialog box that when displayed is centered

    $add = GUICtrlCreateButton("Add", 64, 32, 75, 25)
    $clear = GUICtrlCreateButton("Clear", 64, 72, 75, 25)
    $mylist = GUICtrlCreateList("buttons that have been clicked", 176, 32, 121, 97)
    GUICtrlSetLimit(-1, 200)    ; to limit horizontal scrolling
    GUICtrlSetData(-1, $MESSAGE)
    $close = GUICtrlCreateButton("my closing button", 64, 160, 175, 25)

    GUISetState()

    $msg = 0
    While $msg <> $GUI_EVENT_CLOSE
        $msg = GUIGetMsg()

        Select
            Case $msg = $add
                GUICtrlSetData($mylist, "You clicked button No1|")
            Case $msg = $clear
                GUICtrlSetData($mylist, "")
            Case $msg = $close
                MsgBox(0, "", "the closing button has been clicked", 2)
                Exit
        EndSelect
    WEnd
EndFunc

I would like to enable a horizontal scroll bar on the listbox if the text exceeds the borders. Anyone know how to do it?

nasim007,

Anyone know how to do it?

Yes. :(

Add the horizontal scrollbar style to the control:

$mylist = GUICtrlCreateList("buttons that have been clicked", 176, 32, 121, 97, BitOR($GUI_SS_DEFAULT_LIST, $WS_HSCROLL))

Note the use of BitOR. If you specify a particular style (or extended style), you overwrite the current values, so if you want to keep them you need to specify them as well. As most styles are expressed at the bit level (look at the hex values to see what I mean) merely adding the styles can lead to some strange results. Always use BitOR to make sure the correct bits are set. :)

Melba23,

That makes it three times that you helped me out. Thanks so much. I looked up and down the help file but I didn't know I could apply that style. I thought I was limited to the ListboxConstants.au3 file.

Thanks again!

EDIT: For my program I am populating the listbox with filepaths. Using your suggestion I can make a statically defined limit to the scroll bar using GUICtrlSetLimit. Meaning when the app runs, the empty listbox will already contain a horizonatal scroll bar at a fixed size. Before I go nuts in creating a whole slew of logic blocks trying to figure it out, can I make it so it only appears like the vertical scroll bar; only if the characters exceeds the width of the list box??

nasim007,

You might find these recent topics of interest: :(

Making scrollbars appear only when necessary

Using ellipsis styles

You will have to adapt the techniques used, but they should give you a few pointers on how you might go about it. :)
