Parts

object

Object expression that resolves to a BPCVid object.

button

Integer that on return identifies the button pressed to cause the event. The button parameter is a bit field with bits corresponding to the left button (bit 0), right button (bit 1), and middle button (bit 2). These bits correspond to the values 1, 2, and 4, respectively. Only one of the bits should be set, indicating the button that caused the event.

shift

Integer that corresponds to the state of the SHIFT, CTRL, and ALT keys at the time of the event. The shift parameter is a bit field with the least-significant bits corresponding to the SHIFT key (bit 0), the CTRL key (bit 1), and the ALT key (bit 2). These bits correspond to the values 1, 2, and 4, respectively. Some, all, or none of the bits can be set, indicating that some, all, or none of the keys are pressed. For example, if both CTRL and ALT are pressed, the value of shift is 6.

x

Number that on return specifies the x-coordinate of the current mouse pointer location.

y

Number that on return specifies the y-coordinate of the current mouse pointer location.
