Class PRectangle

scintilla/include/Platform.h:109–149

* A geometric rectangle class. * PRectangle is exactly the same as the Win32 RECT so can be used interchangeably. * PRectangles contain their top and left sides, but not their right and bottom sides. */

 * PRectangles contain their top and left sides, but not their right and bottom sides.
