MouRemovePtr

Notifies the mouse device driver that the area defined by the passed parameters is for the exclusive use of the application. This area is defined as the collision area and is not available to the mouse device driver when drawing pointer images.

Syntax

#define INCL_MOU
#include <os2.h>

PNOPTRRECT    PtrArea;       /* Pointer shape collision area. */
HMOU          DeviceHandle;  /* Reserved.  Must be 0. */
APIRET        rc;            /* Return code. */

rc = MouRemovePtr(PtrArea, DeviceHandle);

Parameters

PtrArea (PNOPTRRECT) - input

Pointer shape collision area.

The address of the pointer shape collision area structure.

DeviceHandle (HMOU) - input

Reserved. Must be 0.

Return Code

rc (APIRET) - returns

MouRemovePtr returns one of the following values:

• 0 NO_ERROR
• 387 ERROR_MOUSE_INV_PARMS
• 466 ERROR_MOU_DETACHED
• 501 ERROR_MOUSE_NO_CONSOLE

Remarks

MouRemovePtr can be issued by any process in the session. However, only one collision area at a time is active. Each call to MouRemovePtr has the effect of resetting the collision area to the location and area specified by the current call.

If the logical pointer position is outside of the collision area specified by the latest MouRemovePtr call, the pointer image is drawn.

The MouDrawPtr call effectively cancels a MouRemovePtr call, allowing the pointer to be drawn anywhere on the screen until the next MouRemovePtr call is issued.
