LImageViewerCell::ActiveSubCellChangedCallBack

#include "ltwrappr.h"

virtual L_INT LImageViewerCell::ActiveSubCellChangedCallBack(hCellWnd, nCellIndex, nSubCellIndex, nPreviousSubCellIndex)

HWND hCellWnd;	handle to the cell window
L_INT nCellIndex;	index of the cell
L_INT nSubCellIndex;	index of the sub-cell
L_INT nPreviousSubCellIndex;	index into the image list attached to the cell

This callback function is called every time the user changes the active sub-cell.

Parameter	Description
hCellWnd	A handle to the window that represents the Medical Viewer Cell.
nCellIndex	A zero-based index of the cell, that contains the sub-cell that been changed.
nSubCellIndex	A zero-based index of the new active sub-cell.
nPreviousSubCellIndex	A zero-based index of the sub-cell that was active before changing the active sub-cell index.

Returns

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

Comments

This callback happens when the sub-cell is changed, which occurs by:

1.	Clicking on another sub-cell rect.
2.	Scrolling the cell scroll.

In order to use this callback function, it must first be set by calling the LImageViewerCell::EnableActiveSubCellChangedCallBack function.

Example

This example will link the active sub-cell of the first cell to the second cell and vice versa.

#ifdef LImageViewerChild 
class LImageViewerChild :public LImageViewerCell 
{ 
   virtual L_INT ActiveSubCellChangedCallBack(HWND hCellWnd, 
   L_INT    nCellIndex, 
   L_INT    nSubCellIndex, 
   L_INT    nPreviousSubCellIndex); 
}; 
#endif 
L_INT LImageViewerChild::ActiveSubCellChangedCallBack(HWND hCellWnd, 
L_INT    nCellIndex, 
L_INT    nSubCellIndex, 
L_INT    nPreviousSubCellIndex) 
{ 
   UNREFERENCED_PARAMETER(hCellWnd); 
   UNREFERENCED_PARAMETER(nCellIndex);

   DISPSTACKACTIONPROPS ActionProperties; 
   DISPCELLPROPERTIES CellProp; 
   CellProp.uStructSize = sizeof(DISPCELLPROPERTIES); 
   CellProp.uMask = DCCELLPF_ROWS | DCCELLPF_COLS; 
   ActionProperties.DispContainerActionProps.uStructSize = sizeof(DISPSTACKACTIONPROPS); 
   GetActionProperties(CONTAINER_ACTION_STACK, 0, &ActionProperties, 0); 
   GetCellProperties(&CellProp, 0); 
   ActionProperties.nActiveSubCell = nSubCellIndex % (CellProp.uNumCols * CellProp.uNumRows); 
   ActionProperties.nScrollValue = nSubCellIndex - ActionProperties.nActiveSubCell; 
   SetActionProperties( CONTAINER_ACTION_STACK, 0, &ActionProperties, CONTAINER_ACTION_CELLLEVEL); 
   return SUCCESS; 
}
