Question

我正在尝试使用列表中的图像创建一个按钮。我希望按钮居中。我的代码如下。我一直收到错误＆＃34;请求'image'中的成员'W'，它是非类型'Fl_GIF_Image（const char *）＆＃34;。我不知道该怎么做。我认为这会给出图像的宽度。有什么想法吗？

    string filename = filenames.at(rand() % filenames.size()); // get randome filename
    cout << "Image File: " << filename << endl; // for debugging

    // Start add code for image on button
    Fl_GIF_Image image(const char* filename);

    Fl_Window *window = new Fl_Window(image.W(), image.H());

    Fl_Button *button = new Fl_Button(0, 0, image.W(), image.H(), filename);
    //button->image();

    //cout << image.w() << "X" << image.h() << endl; // for debugging

    // End code for image on button
    window->end();
    window->show(argc, argv);
    return Fl::run();

找一个也接受Dr.Moore班级的人哈哈并不容易试试这个

    <uc:cpy xmlns:uc="http://oldcompany.com">
     <customerinfo Cid="1004" fid="aa">
        <name>Matt Foreman</name>
        <age>26</age>
     </customerinfo>

     <uc:prodcut xmlns="http://oldcompany.com" xmlns:d="http://test" >
        <uc:item>Hammer</uc:item>
        <uc:quantity>1</uc:quantity>
     </uc:prodcut> 
    </uc:cpy>

希望它有效！
