Description

OnMouseDown event dispatcher.

FMX.Colors.TComboColorBox.MouseDown inherits from FMX.Controls.TControl.MouseDown. All content below this line refers to FMX.Controls.TControl.MouseDown.

OnMouseDown event dispatcher.

A control calls MouseDown in response to any of mouse-down messages, decoding the message parameters into the shift-key state and position, which it passes in the Shift, X, and Y parameters, respectively:

• Button determines which mouse button is pressed: left, right, or middle.
• Shift indicates which shift keys--SHIFT, CTRL, ALT, and CMD (only for Mac)--were down when the user pressed the mouse button.
• X and Y are the pixel coordinates of the mouse pointer within the client area of the control. If Button is mbLeft, MouseDown sets PressedPosition as a TPointF(X,Y).

Override the protected MouseDown method to provide other responses when a mouse button is down while the cursor is over the control.
