#include "ltwrappr.h"

L_INT LImageViewerCell::SetActionProperties (nAction, nSubCellIndex, pActionProperties, uFlags);

L_INT nAction;	/* action ID */

Sets the properties of a specific action.

Parameter	Description
nAction	Value that represents the actions for which to set the properties. If nAction is equal to or greater than 100 it is a user-defined action. Otherwise, it should be one of these predefined actions. Otherwise, it can be one of the following predefined actions:
	Value	Meaning
	CONTAINER_ACTION_WINDOWLEVEL	[1] Window leveling
	CONTAINER_ACTION_SCALE	[2] Scaling
	CONTAINER_ACTION_OFFSET	[3] Offset
	CONTAINER_ACTION_STACK	[4] Stacking
	CONTAINER_ACTION_MAG	[5] Magnifying glass
	CONTAINER_ACTION_ALPHA	[6] Alpha
	CONTAINER_ACTION_ANNOTATION_RULER	[7] Ruler annotation
	CONTAINER_ACTION_ANNOTATION_ANGLE	[8] Angle annotation
	CONTAINER_ACTION_ANNOTATION_TEXT	[9] Text annotation
	CONTAINER_ACTION_ANNOTATION_ARROW	[10] Arrow annotation
	CONTAINER_ACTION_ANNOTATION_RECTANGLE	[11] Rectangle annotation
	CONTAINER_ACTION_ANNOTATION_ELLIPSE	[12] Ellipse annotation
	CONTAINER_ACTION_ANNOTATION_HILITE	[13] Highlight annotation
	CONTAINER_ACTION_REGION_RECTANGLE	[14] Rectangular region
	CONTAINER_ACTION_REGION_ELLIPSE	[15] Elliptical region
	CONTAINER_ACTION_REGION_FREEHAND	[16] Free hand region
	CONTAINER_ACTION_REGION_POLYGON	[17] Polygon region
	CONTAINER_ACTION_REGION_MAGICWAND	[18] Magic wand (contiguous color)region
	CONTAINER_ACTION_REGION_COLORRANGE	[19] Color range region
	CONTAINER_ACTION_REGION_CIRCLE	[20] Circular region
	CONTAINER_ACTION_REGION_SQUARE	[21] Square region
	CONTAINER_ACTION_REGION_NUDGETOOL	[22] Nudge tool
	CONTAINER_ACTION_REGION_SHRINKTOOL	[23] Shrink tool
nSubCellIndex	A zero-based index into the image list attached to the cell. This parameter is only valid when CONTAINER_ACTION_CELLLEVEL is set in uFlags. If uFlags contains CONTAINER_ACTION_CONTAINERLEVEL, this parameter is ignored. Pass -1 to set the properties of a specific action on all sub-cells. Pass -2 to set the properties of a specific action on the selected sub-cell.
pActionProperties	Pointer to a structure that contains the properties to be set. The type of structure pointed to depends on the action specified in the nAction parameter.
	If nAction contains:	then pActionProperties points to this structure:
	CONTAINER_ACTION_WINDOWLEVEL	DISPWLEVELACTIONPROPS
	CONTAINER_ACTION_SCALE	DISPSCALEACTIONPROPS
	CONTAINER_ACTION_OFFSET	DISPOFFSETACTIONPROPS
	CONTAINER_ACTION_STACK	DISPSTACKACTIONPROPS
	CONTAINER_ACTION_MAG	DISPMAGACTIONPROPS
	CONTAINER_ACTION_ALPHA	DISPALPHAACTIONPROPS
	CONTAINER_ACTION_ANNOTATION_RULER	DISPANNOTATIONPROPS
	CONTAINER_ACTION_ANNOTATION_ANGLE	DISPANNOTATIONPROPS
	CONTAINER_ACTION_ANNOTATION_TEXT	DISPANNOTATIONPROPS
	CONTAINER_ACTION_ANNOTATION_ARROW	DISPANNOTATIONPROPS
	CONTAINER_ACTION_ANNOTATION_RECTANGLE	DISPANNOTATIONPROPS
	CONTAINER_ACTION_ANNOTATION_ELLIPSE	DISPANNOTATIONPROPS
	CONTAINER_ACTION_ANNOTATION_HILITE	DISPANNOTATIONPROPS
	CONTAINER_ACTION_REGION_RECTANGLE	DISPREGIONPROPS
	CONTAINER_ACTION_REGION_ELLIPSE	DISPREGIONPROPS
	CONTAINER_ACTION_REGION_FREEHAND	DISPREGIONPROPS
	CONTAINER_ACTION_REGION_POLYGON	DISPREGIONPROPS
	CONTAINER_ACTION_REGION_MAGICWAND	DISPREGIONPROPS
	CONTAINER_ACTION_REGION_COLORRANGE	DISPREGIONPROPS
	CONTAINER_ACTION_REGION_CIRCLE	DISPREGIONPROPS
	CONTAINER_ACTION_REGION_SQUARE	DISPREGIONPROPS
	CONTAINER_ACTION_REGION_NUDGETOOL	DISPNUDGETOOLACTIONPROPS
	CONTAINER_ACTION_REGION_SHRINKTOOL	DISPNUDGETOOLACTIONPROPS
	Owner Action	DISPOWNERACTIONPROPS
uFlags	Flag that determines which properties to set. Possible values are:
	Value	Meaning
	CONTAINER_ACTION_CONTAINERLEVEL	[0x00000000] Set the general properties.
	CONTAINER_ACTION_CELLLEVEL	[0x00000001] Set the specific properties.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

Each of the structures that may be pointed to by pActionProperties contains a member that is a DISPCONTAINERACTIONPROPS structure. Each of these structures also contains one or more other members. The DISPCONTAINERACTIONPROPS structure contains "general properties" that are common to all actions. The other members of the structures are considered may be "general properties" or "specific properties", depending on whether they are applied at the container level or the cell level. Those members that are applied at the container level are also considered "general properties". Members that are applied at the cell level or the sub-cell level are considered "specific properties". For example, if this function is called to set the scale action properties, a variable of type DISPSCALEACTIONPROPS should be declared and the members of that structure set to the desired values. Pass a pointer to this structure for the pActionProperties parameter. To set only the general properties, set uFlags to CONTAINER_ACTION_CONTAINERLEVEL. To set the specific properties, set uFlags to CONTAINER_ACTION_CELLLEVEL.

If this function is not called before applying the action to the container/cell, the default values are used. For more information on these default values, refer to the structures associated with each action.
