L_DispContainerIsCellFrozen

#include "ltivw.h"

L_LTIVW_API L_BOOL L_DispContainerIsCellFrozen(hCellWnd, uFlags)

HWND hCellWnd;	/* handle to the cell window */
L_UINT uFlags;	/* reserved for future use */

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.
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 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.
