DECLARE_WND_CLASS
Allows you to specify the name of a new window class. Place this macro in an ATL ActiveX control's control class.
DECLARE_WND_CLASS(
WndClassName
)
Parameters
- WndClassName
[in] The name of the new window class. If NULL, ATL will generate a window class name.
Remarks
This macro allows you to specify the name of a new window class whose information will be managed by CWndClassInfo. DECLARE_WND_CLASS defines the new window class by implementing the following static function:
static CWndClassInfo& GetWndClassInfo();
DECLARE_WND_CLASS specifies the following styles for the new window:
CS_HREDRAW
CS_VREDRAW
CS_DBLCLKS
DECLARE_WND_CLASS also specifies the default window's background color. Use the DECLARE_WND_CLASS_EX macro to provide your own styles and background color.
CWindowImpl uses the DECLARE_WND_CLASS macro to create a window based on a new window class. To override this behavior, use the DECLARE_WND_SUPERCLASS macro, or provide your own implementation of the GetWndClassInfo function.
For more information about using windows in ATL, see the article ATL Window Classes.
