Description
Is an OnMouseUp event dispatcher.
Vcl.ButtonGroup.TButtonGroup.MouseUp inherits from Vcl.Controls.TControl.MouseUp. All content below this line refers to Vcl.Controls.TControl.MouseUp.
Is an OnMouseUp event dispatcher.
Override the protected MouseUp method to provide other responses in addition to calling the OnMouseUp event handler when the user releases a previously pressed mouse button while the cursor's hot spot is over the control.
A control calls MouseUp in response to any of the Windows mouse-up messages (WM_LBUTTONUP, WM_MBUTTONUP, WM_RBUTTONUP), decoding the message parameters into the shift-key state and position, which it passes in the Shift, X, and Y parameters, respectively. The value of the Button parameter indicates which mouse button was released: left, right, or middle.
