DIRECTMANIPULATION_SNAPPOINT_COORDINATE enumeration (directmanipulation.h)

  • Article

Defines the coordinate system for a collection of snap points.

Syntax

typedef enum DIRECTMANIPULATION_SNAPPOINT_COORDINATE {
  DIRECTMANIPULATION_COORDINATE_BOUNDARY = 0,
  DIRECTMANIPULATION_COORDINATE_ORIGIN = 0x1,
  DIRECTMANIPULATION_COORDINATE_MIRRORED = 0x10
} ;

Constants

 
DIRECTMANIPULATION_COORDINATE_BOUNDARY
Value: 0
Default.

Snap points are specified relative to the top and left boundaries of the content unless DIRECTMANIPULATION_COORDINATE_MIRRORED is also specified, in which case they are relative to the bottom and right boundaries of the content. For zoom, the boundary is 1.0f.
DIRECTMANIPULATION_COORDINATE_ORIGIN
Value: 0x1
Snap points are specified relative to the origin of the viewport.
DIRECTMANIPULATION_COORDINATE_MIRRORED
Value: 0x10
Snap points are interpreted as specified in the negative direction of the origin. The origin is shifted to the bottom and right of the viewport or content. Cannot be set for zoom.

Remarks

If DIRECTMANIPULATION_COORDINATE_ORIGIN and DIRECTMANIPULATION_COORDINATE_MIRRORED are both specified, the snap points are interpreted as specified from the bottom and right boundaries of the content (the size of the content - the size of the viewport). This is intended for RTL reading scenarios where content is normally specified and rendered from right-to-left or bottom-to-top.
