Public Data Members

Name	Description
CWindow::m_hWnd	The handle to the window associated with the CWindow object.
CWindow::rcDefault	Contains default window dimensions.

Remarks

CWindow provides the base functionality for manipulating a window in ATL. Many of the CWindow methods simply wrap one of the Win32 API functions. For example, compare the prototypes for CWindow::ShowWindow and ShowWindow:

CWindow method	Win32 function
BOOL ShowWindow( int nCmdShow);	BOOL ShowWindow( HWND hWnd, int nCmdShow);

CWindow::ShowWindow calls the Win32 function ShowWindow by passing CWindow::m_hWnd as the first parameter. Every CWindow method that directly wraps a Win32 function passes the m_hWnd member; therefore, much of the CWindow documentation will refer you to the Windows SDK.

Note

Not every window-related Win32 function is wrapped by CWindow, and not every CWindow method wraps a Win32 function.

CWindow::m_hWnd stores the HWND that identifies a window. An HWND is attached to your object when you:

Specify an HWND in CWindow's constructor.
Call CWindow::Attach.
Use CWindow's operator =.
Create or subclass a window using one of the following classes derived from CWindow:

CWindowImpl   Allows you to create a new window or subclass an existing window.

CContainedWindow   Implements a window contained within another object. You can create a new window or subclass an existing window.

CDialogImpl   Allows you to create a modal or modeless dialog box.
