Description
MouseDown is called when the user presses a mouse button.
Override the protected MouseDown method to provide a response when the user presses the mouse button while the cursor is over the TDockTree object.
The Button parameter determines which mouse button was pressed. Shift indicates whether the shift keys (SHIFT, CTRL, ALT) are pressed. X and Y are the pixel coordinates of the mouse cursor within the client area of the control. Handled is used to prevent the control from receiving the message.
