Start with the project you created in Setting Container Scaling Values:
Add the following popup menu structure to the main menu you created in the Implementing the Container - Initializing, Creating and Freeing tutorial.
&Draw Object
&Point with ID = IDM_DRAWOBJECT_POINT
&Line with ID = IDM_DRAWOBJECT_LINE
&Square with ID = IDM_DRAWOBJECT_SQUARE
&Rect with ID = IDM_DRAWOBJECT_RECT
&Circle with ID = IDM_DRAWOBJECT_CIRCLE
&Ellipse with ID = IDM_DRAWOBJECT_ELLIPSE
P&olyline with ID = IDM_DRAWOBJECT_POLYLINE
&Bezier with ID = IDM_DRAWOBJECT_BEZIER
&Arc with ID = IDM_DRAWOBJECT_ARC
&Text with ID = IDM_DRAWOBJECT_TEXT
Add the following code to the WndProc
function just before the "return 0L ;" of the WM_CREATE
message:
CheckMenuRadioItem ( GetMenu ( hWnd ),
IDM_DRAWOBJECT_POINT,
IDM_DRAWOBJECT_TEXT,
IDM_DRAWOBJECT_POINT,
MF_BYCOMMAND ) ;
EnableMenuItem ( GetMenu ( hWnd ), 1, MF_BYPOSITION | MF_GRAYED ) ;
Add the following lines to the WndProc
function, after the container metrics block, in the "case IDM_FILE_OPEN" of the WM_COMMAND
message:
EnableMenuItem ( GetMenu ( hWnd ), 1, MF_BYPOSITION | MF_ENABLED ) ;
DrawMenuBar ( hWnd ) ;
Add the following code to the WndProc
function after the "return 0L;" statement of the "case IDM_FILE_EXIT:" statement:
case IDM_DRAWOBJECT_POINT:
L_ContainerSetObjectType ( pContainer, CONTAINER_OBJECT_TYPE_POINT ) ;
CheckMenuRadioItem ( GetMenu ( hWnd ),
IDM_DRAWOBJECT_POINT,
IDM_DRAWOBJECT_TEXT,
IDM_DRAWOBJECT_POINT,
MF_BYCOMMAND ) ;
return 0L ;
case IDM_DRAWOBJECT_LINE:
L_ContainerSetObjectType ( pContainer, CONTAINER_OBJECT_TYPE_LINE ) ;
CheckMenuRadioItem ( GetMenu ( hWnd ),
IDM_DRAWOBJECT_POINT,
IDM_DRAWOBJECT_TEXT,
IDM_DRAWOBJECT_LINE,
MF_BYCOMMAND ) ;
return 0L ;
case IDM_DRAWOBJECT_SQUARE:
L_ContainerSetObjectType ( pContainer, CONTAINER_OBJECT_TYPE_SQUARE ) ;
CheckMenuRadioItem ( GetMenu ( hWnd ),
IDM_DRAWOBJECT_POINT,
IDM_DRAWOBJECT_TEXT,
IDM_DRAWOBJECT_SQUARE,
MF_BYCOMMAND ) ;
return 0L ;
case IDM_DRAWOBJECT_RECT:
L_ContainerSetObjectType ( pContainer, CONTAINER_OBJECT_TYPE_RECT ) ;
CheckMenuRadioItem ( GetMenu ( hWnd ),
IDM_DRAWOBJECT_POINT,
IDM_DRAWOBJECT_TEXT,
IDM_DRAWOBJECT_RECT,
MF_BYCOMMAND ) ;
return 0L ;
case IDM_DRAWOBJECT_CIRCLE:
L_ContainerSetObjectType ( pContainer, CONTAINER_OBJECT_TYPE_CIRCLE ) ;
CheckMenuRadioItem ( GetMenu ( hWnd ),
IDM_DRAWOBJECT_POINT,
IDM_DRAWOBJECT_TEXT,
IDM_DRAWOBJECT_CIRCLE,
MF_BYCOMMAND ) ;
return 0L ;
case IDM_DRAWOBJECT_ELLIPSE:
L_ContainerSetObjectType ( pContainer, CONTAINER_OBJECT_TYPE_ELLIPSE ) ;
CheckMenuRadioItem ( GetMenu ( hWnd ),
IDM_DRAWOBJECT_POINT,
IDM_DRAWOBJECT_TEXT,
IDM_DRAWOBJECT_ELLIPSE,
MF_BYCOMMAND ) ;
return 0L ;
case IDM_DRAWOBJECT_POLYLINE:
L_ContainerSetObjectType ( pContainer, CONTAINER_OBJECT_TYPE_POLYLINE ) ;
CheckMenuRadioItem ( GetMenu ( hWnd ),
IDM_DRAWOBJECT_POINT,
IDM_DRAWOBJECT_TEXT,
IDM_DRAWOBJECT_POLYLINE,
MF_BYCOMMAND ) ;
return 0L ;
case IDM_DRAWOBJECT_BEZIER:
L_ContainerSetObjectType ( pContainer, CONTAINER_OBJECT_TYPE_BEZIER ) ;
CheckMenuRadioItem ( GetMenu ( hWnd ),
IDM_DRAWOBJECT_POINT,
IDM_DRAWOBJECT_TEXT,
IDM_DRAWOBJECT_BEZIER,
MF_BYCOMMAND ) ;
return 0L ;
case IDM_DRAWOBJECT_ARC:
L_ContainerSetObjectType ( pContainer, CONTAINER_OBJECT_TYPE_ARC ) ;
CheckMenuRadioItem ( GetMenu ( hWnd ),
IDM_DRAWOBJECT_POINT,
IDM_DRAWOBJECT_TEXT,
IDM_DRAWOBJECT_ARC,
MF_BYCOMMAND ) ;
return 0L ;
case IDM_DRAWOBJECT_TEXT:
L_ContainerSetObjectType ( pContainer, CONTAINER_OBJECT_TYPE_TEXT ) ;
CheckMenuRadioItem ( GetMenu ( hWnd ),
IDM_DRAWOBJECT_POINT,
IDM_DRAWOBJECT_TEXT,
IDM_DRAWOBJECT_TEXT,
MF_BYCOMMAND ) ;
return 0L ;
Compile and run the project by selecting Build->Rebuild Solution from the menu, and then Debug->Start Without Debugging.
Select File->Open and open any image. Select any of the items in the Draw Object popup menu and begin drawing objects in the container.
