GuiCtrlCreateTreeView + - not showing up until mouseover

[Damein]

So I've created a GUI and a treeview and everything is working as it should I believe but to be able to see the + button in the TreeView I have to mouse over it first. Kinda obnoxious, anyone know why that is?

 

$MainGui = GUICreate("Movie Database - RSSoftware", 800, 600)
    GUISetOnEvent($GUI_EVENT_CLOSE, "_Exit")



    $AZTreeView = GUICtrlCreateTreeView(5, 80, 200, 515, BitOR($TVS_HASBUTTONS, $TVS_HASLINES, $TVS_LINESATROOT, $TVS_DISABLEDRAGDROP, $TVS_SHOWSELALWAYS), $WS_EX_CLIENTEDGE)

    $FavoritesList = GUICtrlCreateTreeViewItem("Favorites", $AZTreeView)

    $NumberList = GUICtrlCreateTreeViewItem("#", $AZTreeView)
    GuiCtrlSetState()

 

And then I populate the list later on. 

 

Thanks!

Cannot reproduce error with this. Could you post some working code with the issue?

[Damein]

Yeah, this actually has the problem in it for me.

If you watch the YouTube demo you can see it in action too.

Damein,

Just redraw the TreeView once you have added the new child - uncomment the line in this script to see the difference:

#include <GUIConstantsEx.au3>
#include <WinAPI.au3>

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

$cTV = GUICtrlCreateTreeView(10, 10, 200, 200)

$cParent = GUICtrlCreateTreeViewItem("Parent 1", $cTV)
GUICtrlCreateTreeViewItem("Child 1A", $cParent)
GUICtrlCreateTreeViewItem("Child 1B", $cParent)
$cParent = GUICtrlCreateTreeViewItem("Parent 2", $cTV)
GUICtrlCreateTreeViewItem("Child 2A", $cParent)
GUICtrlCreateTreeViewItem("Child 2B", $cParent)
$cParent = GUICtrlCreateTreeViewItem("Parent 3", $cTV)

$cAdd = GUICtrlCreateButton("Add child", 10, 450, 80, 30)

GUISetState()

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $cAdd
            GUICtrlCreateTreeViewItem("Child 3A", $cParent)
            ;_WinAPI_RedrawWindow(GUICtrlGetHandle($cTV))
    EndSwitch

WEnd
