标题: SimplyFortran调用appGraphics问题
最近安装了simply Fortran，看见帮助文档里面有appGraphics，就想学学做界面，但是按照help文档里的例子做，却提示出错
程序：

program main

use appgraphics

implicit none

    integer::myscreen

    integer :: root_menu,file_menu,item

    

    interface

        subroutine quit()

        end subroutine quit

    end interface

    interface

        subroutine save()

        end subroutine save

    end interface

    

    myscreen = initwindow(800, 600, closeflag=.TRUE.)

    

    call loop()

    root_menu = addmenu("", MENU_FOR_WINDOW)

    file_menu = addmenu("File", root_menu)

    item = addmenuitem("Save", file_menu, save)

    item = addmenuitem("Quit", file_menu, quit)

    

    call closewindow(myscreen)

end program main

错误提示：

请教是什么原因，是需要一些额外的设置么？

明白了，那个“save”和“quit”是自己写的过程名。。。还以为是编译器已经给写好的。。。

这俩函数需要你自己写。写俩空白的就好了。

  Subroutine quit()

  End Subroutine quit



  Subroutine save()



  End Subroutine save
