Data Structures
class	Graphic2d_Buffer
	This class constructs a 2D graphic buffer in a view. It manages a set of graphic objects and/or primitives. To draw the buffer, the following elements are required: the override color the font a solid line type thickness of 1 pixel. With this category , the user can drag the geometry stored in the buffer without changing the fixed background. This mechanism is reserved for the special driver Aspect_WindowDriver: if no other driver has been defined, nothing will be drawn. Both this driver and view mapping are used to draw the buffer. Warning This class manages dragging only. It does not manage "sketching" or "rubberbanding". For example: There is no empty constructor for this primitive. Therefore we must create a primitive in a dummy object simply to add this primitive to the buffer. There is no Buffer->Add (anArrayOfPoints) method. Therefor it is not possible to add shapes to the buffer. There are no Polyline->ChangeApoint () nor Circle->ChangeRadius () methods. Therefore we must call the primitive's destructor to modify the definition of one primitive in a buffer. The Graphic2d_Image class is a primitive. For this class, we replace the definition of the image with a rectangle with the same size and the same position. You can add or remove primitives to the buffer after creating and displaying it again. More...
