Radiobutton di Delphi

Buat aplikasi baru

Tempatkan 2 buah edit, dua buah label, empat radiobutton dan satu tombol pada form

Ubah sedemikian rupa sehingga menjadi seperti gambar kedua

Dobelklik tombol “Hitung”, isi dengan perintah berikut



if radiobutton1.Checked=true then begin
edit3.Text:=inttostr(strtoint(edit1.Text)+strtoint(edit2.Text));
end else if radiobutton2.Checked=true then begin
edit3.Text:=inttostr(strtoint(edit1.Text)-strtoint(edit2.Text));
end else if radiobutton3.Checked=true then begin
edit3.Text:=inttostr(strtoint(edit1.Text)*strtoint(edit2.Text));
end else if radiobutton4.Checked=true then begin
edit3.Text:=floattostr(strtoint(edit1.Text)/strtoint(edit2.Text));
end;

jalankan program

sebagai pelengkap, tambahkan perintah pada radiobutton sedemikian sehingga jika kita memilih “Pengurangan”, maka otomatis label1 menjadi “-”
