Custom Draw and Owner draw

Posted by kiraninbng on July 6, 2006

Custom draw is a service provided by some of the common controls.Custom draw allows you to make minor changes to the way the items are displayed in the screen.
Currently, the following controls support custom draw functionality:

Header controls
List-view controls
Rebar controls
Toolbar controls
ToolTip controls
Trackbar controls
Tree-view controls

All common controls that support custom draw send NM_CUSTOMDRAW notification messages at specific points during drawing operations. These notifications
describe drawing operations that apply to the entire control as well as drawing operations specific to items within the control. Like many notification messages,
NM_CUSTOMDRAW notifications are sent as WM_NOTIFY messages.
Custom draw feature is somewhere in between the controls default drawing behaviour and the programs owner draw functionality

Owner draw feature allows the customizing the existing controls or lets drawing the control from the scratch.

Currently, the following controls support OwnerDraw functionality:

ListView controls
Static controls
Tab controls

Whenever the item must be drawn Windows sends the WM_DRAWITEM message to the window procedure of the item’s owner window. This message contains a pointer to
a DRAWITEMSTRUCT structure.The application can customize the controls by handling this message.

    Hello Kiran,
    Would it be possible (documentedly or hackingly) to have a shell extension handle a custom draw event for explorer controls, such as the treeview or the listview?
