Description

Is an OnMouseWheelDown event dispatcher.

Vcl.Ribbon.TCustomRibbon.DoMouseWheelDown inherits from Vcl.Controls.TControl.DoMouseWheelDown. All content below this line refers to Vcl.Controls.TControl.DoMouseWheelDown.

Is an OnMouseWheelDown event dispatcher.

The DoMouseWheel method calls DoMouseWheelDown to generate an OnMouseWheelDown event.

The Shift parameter indicates the state of the SHIFT, ALT, and CTRL keys.

The MousePos parameter indicates the position of the mouse pointer.

DoMouseWheelDown returns true if an event handler indicates that it handled the message, and false otherwise.

Override DoMouseWheelDown to perform class-specific tasks in addition to calling the event handler when the mouse wheel is rotated downward.
