waltzie · January 23, 2009

Any help is really appreciated

Thanks mutch

GREAT MAN!

Tnxvm

Thanks.

but ... How can i manage more than One same level root?

Delete work well, but how to add root context menu "Add" for each Tree root item?

(no dummy context menu, exist something for Contextmenu press like Case $NM_RCLICK )

This is the Example that need to add functionality to add/remove on $NM_RCLICK

Thanks mutch for any help

Hello!

Use the _GUICtrlTreeView_SetSelectedImageIndex function.

Example:

_GUIImageList_AddIcon($hImage, "shell32.dll", 165)
_GUIImageList_AddIcon($hImage, "shell32.dll", 137)
_GUIImageList_AddIcon($hImage, "shell32.dll", 131)

_GUICtrlTreeView_SetNormalImageList($maintree, $hImage)

$aboutitem = GUICtrlCreateTreeViewItem("Parent", $maintree)
For $i = 1 To 2
    GUICtrlCreateTreeViewItem("Child " & $i, $aboutitem)
Next

@waltzie
Hello!
.....

Thanks, but there is still a little bug...

If i set a Item to play, next time that i rightclick on each other (ever not played) items i see in dummy meny STOP.

SOLVED!

In WM_NOTIFY on $NM_RCLICK

add:

If _GUICtrlTreeView_GetParentHandle($hWndTreeView, $hItem) = 0 Then
$hTreeView_Parent = $hItem
GUICtrlSendToDummy($cDummyMenu)
;give control to root entity menu
Else
if _GUICtrlTreeView_GetSelectedImageIndex($hWndTreeView, $hItem) = 2 Then
GUICtrlSetData($aboutitemMenuItems_Play, "Play Item")
Else
GUICtrlSetData($aboutitemMenuItems_Play, "Stop Item")
EndIf
;give control to item menu
GUICtrlSendToDummy($cDummy2)
EndIf
