The DISPOFFSETACTIONPROPS structure contains the properties for controlling the Offset action.
typedef struct tagDISPOFFSETACTIONPROPS{DISPCONTAINERACTIONPROPS DispContainerActionProps;L_INT nXOffset;L_INT nYOffset;L_BOOL bRelativeSensitivity;} DISPOFFSETACTIONPROPS, * pDISPOFFSETACTIONPROPS;
A structure that contains the general action properties. This member is applied on the container
The X offset of the image. This value is given pixels and is with respect to the center of the cell. This member is applied on the cell level. Default is 0.
The Y offset of the image. This value is given pixels and is with respect to the center of the cell. This member is applied on the cell level. Default is 0.
Flag that indicate whether to allow the control to adjust the offset action mouse sensitivity based on the current scale of the image. This will allow more stable offset movement when the image is scaled up or scaled down. Possible values are:
| Value | Meaning |
|---|---|
| TRUE | Use the relative sensitivity feature. |
| FALSE | Do not used the relative sensitivity feature. This is the default value. |
For each action supported by the image viewer, there are general properties and specific properties. The general properties are those that are common to all actions and are applied at the container level. Each structure specific for an action contains a member that is a DISPCONTAINERACTIONPROPS structure and 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 "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".
To get or set the general action properties and any "Container-level" properties in this structure, call L_DispContainerGetActionProperties or L_DispContainerSetActionProperties with uFlags to CONTAINER_ACTION_CONTAINERLEVEL.
To get or set the specific action properties, "Cell-level" or "Sub-cell level" properties in this structure, call L_DispContainerGetActionProperties or L_DispContainerSetActionProperties with uFlags to CONTAINER_ACTION_CELLLEVEL.
