Simple Drawing Functions

The CDC class offers a series of member functions that correspond to low-level GDI drawing operations. Among these is the function FillRect (fills a rectangle with a specific brush), FillSolidRect (fills a rectangle with a specific color), FrameRect (draws the borders of a rectangle), and InvertRect (inverts the interior of a rectangle). Analogous functions that accept regions as their parameters are FillRgn, FrameRgn, and InvertRgn.

Additional functions include DrawIcon (draws an icon) and DrawDragRect (erases and draws a dragging rectangle). Other simple drawing functions assist in drawing controls in various (selected, deselected) states and with various border settings.
