With the aid * of a helper class (os2FrameWindow) and a subclass (nsChildWindow), * it implements the functionality of both toplevel and child widgets. * * Top-level widgets (windows surrounded by a frame with a titlebar, etc.) * are created when NS_WINDOW_CID is used to identify the type of object * needed. Child widgets (windows that either are children of other windows * or are popups such as menus) are created when NS_CHILD_CID is specified. * Since Mozilla expects these to be different classes, NS_CHILD_CID is * mapped to a subclass (nsChildWindow) which acts solely as a wrapper for * nsWindow and adds no functionality. * * While most of the methods inherited from nsIWidget are generic, some * apply only to toplevel widgets (e.g. setting a title or icon). The * nature of toplevel windows on OS/2 with their separate frame & client * windows introduces the need for additional toplevel-specific methods, * as well as for special handling in otherwise generic methods. * * Rather than incorporating these toplevel functions into the body of * the class, nsWindow delegates them to a helper class, os2FrameWindow. * An instance of this class is created when nsWindow is told to create * a toplevel native window and is destroyed in nsWindow's destructor. * The class's methods operate exclusively on the frame window and never * deal with the frame's client other than to create it. Similarly, * nsWindow never operates on frame windows except for a few trivial * methods (e.g. Enable()). Neither class accesses the other's data * though, of necessity, both call the other's methods. * */ //============================================================================= #ifndef _nswindow_h #define _nswindow_h #include "nsBaseWidget.h" #include "gfxASurface.h" #define INCL_DOS #define INCL_WIN #define INCL_NLS #define INCL_GPI #include #include //----------------------------------------------------------------------------- // Items that may not be in the OS/2 Toolkit headers // For WM_MOUSEENTER/LEAVE, mp2 is the other window. #ifndef WM_MOUSEENTER #define WM_MOUSEENTER 0x041E #endif #ifndef WM_MOUSELEAVE #define WM_MOUSELEAVE 0x041F #endif #ifndef WM_FOCUSCHANGED #define WM_FOCUSCHANGED 0x000E #endif extern "C" { PVOID APIENTRY WinQueryProperty(HWND hwnd, PCSZ pszNameOrAtom);
