using namespace std;

const int ID_SLIDER = 1;

class MyFrame : public wxFrame

};

}

MyFrame::MyFrame()
    : wxFrame(NULL,-1,"slider test",wxDefaultPosition,wxSize(400,400))
{
    wxPanel *panel = new wxPanel(this);
    slider = new wxSlider(panel,ID_SLIDER,0,0,100,wxPoint(10,40),wxSize(240,-1));

}
