For example, you have 2 SpeedButtons and you want to use them like buttons on toolbar. Use for this GroupIndex, Down and AllowAllUp properties of SpeedButtons.
Button1 is a usual button, which allows you to set your SpeedButtons to stick down.
And Button2 allows you to set properties of SpeedButtons as normal buttons.
procedure TForm1.Button1Click(Sender: TObject);
begin
SpeedButton1.GroupIndex:=1;
SpeedButton2.GroupIndex:=1;
end;
procedure TForm1.Button2Click(Sender: TObject);
begin
SpeedButton1.GroupIndex:=0;
SpeedButton2.GroupIndex:=0;
if SpeedButton1.Down=True then
with SpeedButton1 do
begin
AllowAllUp:=True;
Down:=False;
AllowAllUp:=True;
end;
if SpeedButton2.Down=True then
with SpeedButton2 do
begin
AllowAllUp:=True;
Down:=False;
AllowAllUp:=True;
end;
