Returns a value that indicates whether the specified cell is frozen.

Parameter

Description

hCellWnd

A handle to the window that represents the cell on which the function's effect will be applied.

Reserved for future use. Pass 0.

Returns

TRUE

The cell is frozen.

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_LTIVWTEX_API  L_INT DispContainerIsCellFrozenExample(HDISPCONTAINER hCon) 
{ 
   L_INT nRet; 
   // Get the cells count. 
   L_INT nCount = L_DispContainerGetCellCount (hCon, 0); 
   L_INT nI; 
   for (nI = 0; nI < nCount; nI++) 
   { 
      HWND hCellWnd = L_DispContainerGetCellWindowHandle(hCon, nI, 0); 
      // if there is a selected cell make it unselected and vice versa 
      L_BOOL bFreezed = L_DispContainerIsCellFrozen(hCellWnd, 0); 
      if (bFreezed) 
      { 
         nRet = L_DispContainerFreezeCell (hCellWnd, FALSE, 0); 
         if(nRet != SUCCESS) 
            return nRet;
