"Down" property in SpeedButton?

[tappatappa]

Can someone explain to me how does UniSpeedButton->Down works?

My guess is that SpeedButton has two states (Down and Up) and can be used as a "checkbox" (Checked true/false), but

void __fastcall TForm1::ButtonSpeedClick(TObject *Sender)
{
	ButtonSpeed->Down = !ButtonSpeed->Down;
}

does nothing (graphically)

You are on the right track, look at the attached example.

Thanks for your reply. In order to make it work for a single SpeedButton I had to implement a little trick

void __fastcall TForm1::ButtonSpeedAClick(TObject *Sender)
{
	static bool speedAstate = false;
	ButtonSpeedA->Down = !speedAstate;
	speedAstate = !speedAstate;
}
