Members

dwMousePosition

Specifies the location of the cursor in terms of the screen buffer’s character-cell coordinates.

dwButtonState

Indicates the status of the mouse buttons. The least significant bit corresponds to the leftmost mouse button. The next least significant bit corresponds to the rightmost mouse button. The next bit indicates the next-to-leftmost mouse button. The bits then correspond left to right to the mouse buttons. A bit is 1 if the button was pressed.

The following constants are defined for the first five mouse buttons:

FROM_LEFT_1ST_BUTTON_PRESSED
RIGHTMOST_BUTTON_PRESSED
FROM_LEFT_2ND_BUTTON_PRESSED
FROM_LEFT_3RD_BUTTON_PRESSED
FROM_LEFT_4TH_BUTTON_PRESSED

dwControlKeyState

Indicates the state of the control keys. This member can be a combination of the following values:

Value	Meaning
RIGHT_ALT_PRESSED	The right ALT key is pressed.
LEFT_ALT_PRESSED	The left ALT key is pressed.
RIGHT_CTRL_PRESSED	The right CTRL key is pressed.
LEFT_CTRL_PRESSED	The left CTRL key is pressed.
CAPSLOCK_ON	The CAPS LOCK light is on.
ENHANCED_KEY	The key is enhanced.
NUMLOCK_ON	The NUM LOCK light is on.
SCROLLLOCK_ON	The SCROLL LOCK light is on.
SHIFT_PRESSED	The SHIFT key is pressed.

dwEventFlags

Indicates the type of mouse event. If this value is zero, it indicates a mouse button being pressed or released. Otherwise, the value is one of the following:

Value	Meaning
DOUBLE_CLICK	The second click (button press) of a double-click occurred. The first click is returned as a regular button-press event.
MOUSE_MOVED	A change in mouse position occurred.

Remarks

Mouse events are placed in the input buffer when the console is in mouse mode (ENABLE_MOUSE_INPUT).

Mouse events are generated whenever the user moves the mouse, or presses or releases one of the mouse buttons. Mouse events are placed in a console’s input buffer only when the console group has the keyboard focus and the cursor is within the borders of the console’s window.
