DIMOUSESTATE2 Structure

Describes the state of a mouse device that has up to eight buttons, or another device that is being accessed as if it were a mouse device. This structure is used with the IDirectInputDevice8::GetDeviceState method.

Syntax

typedef struct DIMOUSESTATE2 {
    LONG lX;
    LONG lY;
    LONG lZ;
    BYTE rgbButtons[8];
} DIMOUSESTATE2, *LPDIMOUSESTATE2;

Members

lX
X-axis.
lY
Y-axis.
lZ
Z-axis, typically a wheel. If the mouse does not have a z-axis, the value is 0.
rgbButtons
Array of buttons. The high-order bit of the byte is set if the corresponding button is down.

Remarks

You must prepare the device for mouse-style access by calling the IDirectInputDevice8::SetDataFormat method, passing the c_dfDIMouse2 global data format variable.
The mouse is a relative-axis device, so the absolute axis positions for mouse axes are accumulated relative motion. Therefore, the value of the absolute axis position is not meaningful except in comparison with other absolute axis positions.
If an axis is in relative mode, the appropriate member contains the change in position. If it is in absolute mode, the member contains the absolute axis position.
