class TGMainFrame: public TGCompositeFrame

 Create a top level main frame. A main frame interacts
 with the window manager.

 TGMainFrame destructor.

 Opens dialog window allowing user to save the frame contents
 as a ROOT macro or as an image.
 Returns kTRUE if something was saved.

 This is bound to Ctrl-S by default.

 Handle keyboard events.

 Bind key to a window.

 Remove key binding.

 Handle mouse button events.

 Handle mouse motion events.

 Handle primary selection event.

 Handle selection request event.

 Handle client messages sent to this frame.

 Send close message to self. This method should be called from
 a button to close this window.

 Close and delete main frame. We get here in response to ALT+F4 or
 a window manager close command. To terminate the application when this
 happens override this method and call gApplication->Terminate(0) or
 make a connection to this signal (if after the slot this method
 should not be called call DontCallClose() in the slot).
 By default the window will be deleted.

 Typically call this method in the slot connected to the CloseWindow()
 signal to prevent the calling of the default or any derived CloseWindow()
 methods to prevent premature or double deletion of this window.

 Set window name. This is typically done via the window manager.

 Set window icon name. This is typically done via the window manager.

 Set window icon pixmap by name. This is typically done via the window
 manager. Icon can be in any image format supported by TImage, e.g.
 GIF, XPM, PNG, JPG .. or even PS, PDF (see EImageFileTypes in TImage.h
 for the full list of supported formats).

 For example,
    main_frame->SetIconPixmap("/home/root/icons/bld_rgb.png");

 Set window icon by xpm array. That allows to have icons
 builtin to the source code.

 For example,
    #include "/home/root/icons/bld_rgb.xpm"
    //bld_rgb.xpm contains char *bld_rgb[] array
    main_frame->SetIconPixmap(bld_rgb);

 Set the windows class and resource name. Used to get the right
 resources from the resource database. However, ROOT applications
 will typically use the .rootrc file for this.

 Set decoration style for MWM-compatible wm (mwm, ncdwm, fvwm?).

 Give the window manager a window position hint.

 Give the window manager a window size hint.

 Give the window manager minimum and maximum size hints. Also
 specify via winc and hinc the resize increments.

 Set the initial state of the window. Either kNormalState or kIconicState.

 Returns MWM decoration hints as a string - used in SavePrimitive().

 Returns MWM function hints as a string - used in SavePrimitive().

 Returns MWM input mode hints as a string - used in SavePrimitive().

 Save the GUI main frame widget in a C++ macro file.

 Save a main frame widget as a C++ statement(s) on output stream out.
