"subclass" a window in the C API sense of the term. It is a base class, meant to be derived from. Derived classes should provide an interface that will call <a class="el" href="class_csubclasswnd.html#b6">CSubclassWnd::SubclassWindow</a>() in order to hook into a window's message handling interface. Typically this will be done in the derived's constructor and the OnFinalMessage method will be overriden to delete the object's instance (delete this).<p><hr><h2>Member Function Documentation</h2><a name="b5" doxytag="CSubclassWnd::DefWindowProc"><p><table width=100%% cellpadding=2 cellspacing=0 border=0><tr><td class="md"><b>LRESULT CSubclassWnd::DefWindowProc (UINT <em>message</em>, WPARAM <em>wParam</em>, LPARAM <em>lParam</em>)<code> [inline, protected]</code></b></td></tr></table></a><div class="in"><p>Calls the "default" window procedure with the specified message.<p>The "default" procedure is what ever procedure was subclassed by this class.<p><dl compact><dt><b>Parameters: </b><dd><table border=0 cellspacing=2 cellpadding=0><tr><td valign=top><em>message</em> </td><td> [in] Specifies the message id. </td></tr><tr><td valign=top><em>wParam</em> </td><td> [in] Specifies additional message-specific information. </td></tr><tr><td valign=top><em>lParam</em> </td><td> [in] Specifies additional message-specific information.<p></td></tr></table></dl><dl compact><dt><b>Returns: </b><dd> The return value is the result of the message processing and depends on the message.</dl></div><a name="b4" doxytag="CSubclassWnd::DefWindowProc"><p><table width=100%% cellpadding=2 cellspacing=0 border=0><tr><td class="md"><b>LRESULT CSubclassWnd::DefWindowProc ()<code> [inline, protected]</code></b></td></tr></table></a><div class="in"><p>Calls the "default" window procedure with the current message.<p>The "default" procedure is what ever procedure was subclassed by this class.<p><dl compact><dt><b>Returns: </b><dd> The return value is the result of the message processing and depends on the message.</dl></div><a name="a0" doxytag="CSubclassWnd::GetCurrentMessage"><p><table width=100%% cellpadding=2 cellspacing=0 border=0><tr><td class="md"><b>const MSG * CSubclassWnd::GetCurrentMessage () const<code> [inline]</code></b></td></tr></table></a><div class="in"><p>Retrieves a pointer to the "current" MSG structure being handled.<p><dl compact><dt><b>Returns: </b><dd> Returns a pointer to the "current" MSG structure being handled.</dl></div><a name="a1" doxytag="CSubclassWnd::GetHandle"><p><table width=100%% cellpadding=2 cellspacing=0 border=0><tr><td class="md"><b>HWND CSubclassWnd::GetHandle () const<code> [inline]</code></b></td></tr></table></a><div class="in"><p>Called to get the handle of the subclassed window.<p><dl compact><dt><b>Returns: </b><dd> The handle to the currently subclassed window.</dl></div><a name="a3" doxytag="CSubclassWnd::PostMessage"><p><table width=100%% cellpadding=2 cellspacing=0 border=0><tr><td class="md"><b>BOOL CSubclassWnd::PostMessage (UINT <em>message</em>, WPARAM <em>wParam</em> = 0, LPARAM <em>lParam</em> = 0)<code> [inline]</code></b></td></tr></table></a><div class="in"><p>Posts a message to the subclassed window.<p><dl compact><dt><b>Parameters: </b><dd><table border=0 cellspacing=2 cellpadding=0><tr><td valign=top><em>message</em>⌨️ 快捷键说明
