LImageViewer::SetActionProperties

#include "ltwrappr.h"

L_INT LImageViewer::SetActionProperties (nAction, nCellIndex, nSubCellIndex, pActionProperties, uFlags);

L_INT nAction;	/* action ID */
L_INT nCellIndex;	/* index of the affected cell */
L_INT nSubCellIndex;	/* index into the image list attached to the cell */
LONG pActionProperties;	/* pointer to a structure */
L_UINT uFlags;	/* type of properties */

Sets the properties of a specific action. This function is available only in the Medical Imaging Suite toolkits.

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.
	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
nCellIndex	A zero-based index of the cell for which to set the action properties. This parameter is only valid when CONTAINER_ACTION_CELLLEVEL is set in uFlags. If uFlags contains CONTAINER_ACTION_CONTAINERLEVEL, this parameter is ignored.
nSubCellIndex	A zero-based index into the image list attached to the cell specified in nCellIndex. This parameter is only valid when CONTAINER_ACTION_CELLLEVEL is set in uFlags. If uFlags contains CONTAINER_ACTION_CONTAINERLEVEL, this parameter is ignored.
pActionProperties	Pointer to a structure that contains the properties to 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
	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.
