LImageViewer::IsCellFrozen

#include "ltwrappr.h"

L_BOOL LImageViewer::IsCellFrozen (nCellIndex, uFlags);

L_INT nCellIndex;	/* index of the cell */
L_UINT uFlags;	/* reserved for future use */

Returns a value that indicates whether the specified cell is frozen. This function is available only in the Medical Imaging Suite toolkits.

Parameter	Description
nCellIndex	A zero-based index of the cell for which to determine the freeze status.
uFlags	Reserved for future use. Pass 0.

Returns

TRUE	The cell is frozen.
FALSE	The cell is not frozen, or an error occurred. To get extended error information, call GetLastError.

Comments

To freeze or un-freeze a cell, call LImageViewer::FreezeCell.

When a cell is frozen no actions using the mouse or the keyboard can be performed on the cell. Some cell properties can still be changed manually however, using LImageViewer::SetCellProperties, LImageViewer::SelectCell and LImageViewer::SetProperties. For more information on actions associated with a container, refer to Applying Actions.

Example

This procedure unfreezes any frozen cell.

L_INT LImageViewer_IsCellFrozenExample(LImageViewer& ImageViewer) 
{
   // Get the cells count. 
   L_INT    nCount = ImageViewer.GetCellCount(0); 
   L_INT    nI; 
   L_INT    nRet = 0 ; 
   // if there is a Frozen cell, make it unFrozen and vice versa
   for (nI = 0; nI < nCount; nI++)
   {
      nRet = ImageViewer.FreezeCell(nI, !ImageViewer.IsCellFrozen(nI, 0), 0); 
      if(nRet != SUCCESS)
         return nRet;
   }
   return SUCCESS;
