Question:
Some components do not respond to a cursor change
until the user moves the mouse. Is there a way to simulate
a mouse move?
Answer:
The following example shows how to "nudge the mouse"
without user intervention.
procedure TForm1.Button1Click(Sender: TObject);
var
pt : TPoint;
begin
Application.ProcessMessages;
Screen.Cursor := CrHourglass;
GetCursorPos(pt);
SetCursorPos(pt.x + 1, pt.y + 1);
Application.ProcessMessages;
SetCursorPos(pt.x — 1, pt.y — 1);
end;
