Whcih paint message to catch for TreeView Ctrl

[usman999_1]

Hi*!
I am creating a TreeView Control at run time by using createwindow. I am want the TreeView to be drawn transparently so that i can show a bitmap that the main window contains. I am thinking of Doing something like

SetBkMode(handleto_treeCtrl, TRANPARENT);
return /* creating an returning with a NULL brush to draw the background */; 

Please correct me if i am wrong. My problem is find the message that the control gets before it starts drwaing. I sraeched for something like WM_CTRLCLR** but there isn't anything for the treeview ctrl. I am using Win32 not MFC.
Secondly if there is another way to draw TreeView Ctrl transparently plz DO tell me. I'll be oblighed.
Regards,
Usman.

Hi Usman,

Look at

COLORREF TreeView_SetBkColor(
    HWND hwndTV 
    COLORREF clrBk;
);

Thanks Emi for your reply. The problem is i don't want to set the background color to any other color. I want to make the TreeView background TRANSPARENT so that the window containg the treeview showsup. I am displaying a bitmap at the main window.
Thanks,
Usman.

Hi!!!!!!!

Have a look at this article. It does not exactly draw a CTreeCtrl with a transparent background, but with a background bitmap, maybe this will fit your needs.
