Below is sample code on how to create a Legend using subwindows. Legend remain the same size when you re-size your main window.

void CSolidHoopsView::OnExtraSlot5() {


    HC_Open_Segment_By_Key(m_pHView->GetViewKey()); {
            

        HC_Open_Segment("legend"); {

            // set a anchor point on top-left corner of the main window
            // offsets=(left, right, down, up)  represent the size of your subwindow in pixels.
            // HC_Set_Window_With_Options(-1, -1, 1, 1, "offsets=(0, 150, -400, 0)");

            // set a anchor point on top-right corner of the main window
            // offsets=(left, right, down, up)  represent the size of your subwindow in pixels.
             HC_Set_Window_With_Options(1, 1, 1, 1, "offsets=(-150, 0, -400, 0)");

            // set a anchor point on bottom-left corner of the main window
            // offsets=(left, right, down, up)  represent the size of your subwindow in pixels.
            // HC_Set_Window_With_Options(-1, -1, -1, -1, "offsets=(0, 150, 0, 400)");

            // set a anchor point on bottom-right corner of the main window
            // offsets=(left, right, down, up)  represent the size of your subwindow in pixels.
            // HC_Set_Window_With_Options(1, 1, -1, -1, "offsets=(-150, 0, 0, 400)");


            HC_Set_Window_Pattern("invisible");
            HC_Set_Visibility("geometry=on,vertices=off");

                HC_Read_Metafile("D:/SDHV/legend.hmf", ".", "");

                HPoint position, target, up;
                float field_width, field_height;

                position.Set(0, 0, 1);
                target.Set(0, 0, 0);
                up.Set(0, 1, 0);


                HC_Set_Camera(&position, &target, &up, 0.5f, 0.5f, "orthographic");

                HC_Dolly_Camera(-0.2f, -0.7f, 0);


        } HC_Close_Segment();

    } HC_Close_Segment();

    m_pHView->Update();
}
