L_LTIVW_API L_INT L_DispContainerSetPaintCallBack(hCon, pfnPaintCallBack, pUserData)

HDISPCONTAINER hCon;	/* handle to the container */
DISPCONTAINERPAINTCALLBACK pfnPaintCallBack;	/* callback function */
L_VOID * pUserData;	/* pointer to more parameters for the callback */

Sets a callback function, which lets the user paint on the cell. This function is available only in the Medical Imaging Suite toolkits.

Parameter	Description
hCon	Handle to the container.
pfnPaintCallBack	Callback function that is called every time the cell needs to be repainted. The callback function must adhere to the function prototype described in DISPCONTAINERPAINTCALLBACK
pUserData	Void pointer that you can use to pass one or more additional parameters that the callback function needs. To use this feature, assign a value to a variable or create a structure that contains as many fields as you need. Then, in this parameter, pass the address of the variable or structure, casting it to L_VOID. The callback function, which receives the address in its own pUserData* parameter, can cast it to a pointer of the appropriate data type to access your variable or structure. If the additional parameters are not needed, you can pass NULL in this parameter.

Returns

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

Comments

To get the current paint callback function, call the L_DispContainerGetPaintCallBack function.
