L_DispContainerUpdateCellView

#include "l_bitmap.h"

L_LTIVW_API L_INT EXT_FUNCTION L_DispContainerUpdateCellView(hCellWnd, uFlags)

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

Recalculates the cells internal values in order to update the view according to the new change made on the image.

Parameter	Description
hCellWnd	A handle to the window that represents the Medical Viewer Cell.
uFlags	Reserved for future use. Pass 0.

Returns

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

Comments

This function is useful when the user applies a certain effect on the cell image that causes the image dimensions to change.

This function will also repaint the cell. To repaint the cell only with recalculated internal data, use the L_DispContainerRepaintCell function.

To stop repainting while applying a series of effects without refreshing each time an effect is applied, use the function L_DispContainerBeginUpdate to stop the cell from repainting, and then use the function L_DispContainerBeginUpdate to repaint everything.
