L_DispContainerIsCellFrozen

#include "ltivw.h"

L_BOOL EXT_FUNCTION L_DispContainerIsCellFrozen(hCon, nCellIndex, uFlags)

HDISPCONTAINER hCon;	/* handle to the container */
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
hCon	Handle to the container.
nCellIndex	A zero-based index of the cell for which to determine the freeze status.
uFlags	Reserved for future use. Must be zero.

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 L_DispContainerFreezeCell.

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 L_DispContainerSetCellProperties, L_DispContainerSelectCell and L_DispContainerSetProperties. For more information on actions associated with a container, refer to Applying Actions.

Example

// This procedure unfreezes any frozen cell
L_VOID UnfreezeCell(HDISPCONTAINER hCon)
{
   // Get the cells count.
   L_INT nCount = L_DispContainerGetCellCount (hCon, 0);
   L_INT nI;

   for (nI = 0; nI < nCount; nI++)
   {
      // if there is a selected cell make it unselected and vice versa
      L_BOOL bFreezed = L_DispContainerIsCellFrozen (hCon, nI, 0);
      if (bFreezed)
         L_DispContainerFreezeCell (hCon, nI, FALSE, 0);
   }
