}


func (f *TMainForm) OnFormCreate(sender vcl.IObject) {
    f.SetCaption("Hello")
    f.Btn1 = vcl.NewButton(f)

)

func main() {
    vcl.Application.Initialize()
    vcl.Application.SetMainFormOnTaskBar(true)
    vcl.Application.CreateForm(mainFormBytes, &mainForm)
    vcl.Application.Run()
}


func (f *TMainForm) OnFormCreate(sender vcl.IObject) {
