SNAPINFO Struct Reference

#include <MDISnapper.h>

---

Detailed Description

holds the data for calculating a modified window rect.

Since it only works on coordinate rects, it can be used without any actual Windows. To use it:

• call Init, specifying the initial position
• call SnapHLine / SnapVLine for each (virtual) line to snap to
• call EndSnap to retrieve the final position

Definition at line 21 of file MDISnapper.h.

Public Types
enum	{ MAXDELTA = (1<<30) }
Public Methods
void	Init (RECT const &oldRect, RECT const &newRect, DWORD snapwidth)
	Initialize, specifying a pre-move and post-move rect.
void	Init (RECT const &r, DWORD snapWidth, bool moveOnly=false)
	Initialize, specifying only one rectangle.
void	SnapHLine (long y)
	snap to a horizontal line
void	SnapVLine (long x)
	snap to a vertical line
RECT &	EndSnap ()
	ends snapping sequence and returns final coords
Data Fields
DWORD	snapWidth
	distance over which snapping works
RECT	rold
	original rect
RECT	rnew
	post-move rect (if specified)
RECT	rdelta
RECT	rout
	accumulates the final rect
