TreeGadget() & Ugly black & red checkered border

[Thunder93]

Working with TreeGadget() under Windows 10 w/ Latest PB stable release.

The selected item in the list gets an ugly black & red checkered border. If I switch to another screen and come back to it, all is normal, and I can select around and It'll be good.

I coudnt reproduce the issue here.

Nothing fancy for code, simply using the PB Help TreeGadget() sample code. Using default Windows 10 Theme.

Great!

Black and dark yellow checkered border here!

Obviously Windows 10 theme driven feature. When you return focus to a window and pres "Ctrl", same frame/border appears.

Code: Select all

If OpenWindow(0, 0, 0, 355, 180, "TreeGadget", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
  tree = CreateWindowEx_(#Null, #WC_TREEVIEW, "Tree View", #WS_VISIBLE|#WS_BORDER|#WS_CHILDWINDOW|#TVS_HASLINES,10, 10, 160, 160, WindowID(0), #Null, GetModuleHandle_(0), #Null)
  TreeGadget(1, 180, 10, 160, 160, #PB_Tree_NoLines)
  For i = 1 To 5
    NodeText.s = "Item " + Str(i)
    tvi.TV_INSERTSTRUCT\hParent = hItemParent
    tvi.TV_INSERTSTRUCT\hInsertAfter = #TVI_LAST
    tvi.TV_INSERTSTRUCT\Item\Mask = #TVIF_TEXT 
    tvi.TV_INSERTSTRUCT\Item\pszText = @NodeText
    tvi.TV_INSERTSTRUCT\Item\cchTextMax = Len(NodeText)  
    SendMessage_(tree, #TVM_INSERTITEM, #Null, @tvi)
    AddGadgetItem (1, -1, "Item " + Str(i), #Null, #Null)
  Next
  Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow
EndIf

I've noticed the reappearance earlier when I was pressing ALT.

I wonder why other applications using the same class doesn't suffer from this then. If it is truly new style in Windows 10 ... which I find it really difficult to believe. Windows Device Manager and other apps using same class .. doesn't suffer from this anomaly.

[bbanelli]

Well, I've called native WinAPI and same thing happens.

Funny, though, if you try access "Class" tab in WinSpy++ with any PB application in Windows 10 (including PB IDE), it crushes spied application immediately.

No,no black border with Win API
Only with PB

Strange behavior
If the TreeGadget followed by even a dummy ButtonGadget it looks fine

Code: Select all

  If OpenWindow(0, 0, 0, 355, 180, "TreeGadget", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
    TreeGadget(0, 10, 10, 160, 160)                                         ; TreeGadget standard
    TreeGadget(1, 180, 10, 160, 160, #PB_Tree_CheckBoxes | #PB_Tree_NoLines)  ; TreeGadget with Checkboxes + NoLines
    For ID = 0 To 1
      For a = 0 To 10
        AddGadgetItem (ID, -1, "Normal Item "+Str(a), 0, 0) ; if you want to add an image, use
        AddGadgetItem (ID, -1, "Node "+Str(a), 0, 0)        ; ImageID(x) as 4th parameter
        AddGadgetItem(ID, -1, "Sub-Item 1", 0, 1)    ; These are on the 1st sublevel
        AddGadgetItem(ID, -1, "Sub-Item 2", 0, 1)
        AddGadgetItem(ID, -1, "Sub-Item 3", 0, 1)
        AddGadgetItem(ID, -1, "Sub-Item 4", 0, 1)
        AddGadgetItem (ID, -1, "File "+Str(a), 0, 0) ; sublevel 0 again
      Next
    Next
  ButtonGadget(2,0,0,0,0,"Test 2")
    Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow
  EndIf

Looks fine until you press certain keys.

[Thunder93]

the filling of the backcolor of the selected control is incomplete. Also ListViewGadget also effected, however with very slight difference.

[Fred]

Seems to work as expected here, can anybody else confirm ?

Using the TreeGadget() example code with PB 6.02LTS under Windows 10 22H2 w/Latest patches, I'm still experiencing the same thing.
