  这两天工作搞了下QT，主要是为了实现一个功能，跨平台用的。功能是这样的，根据一个页面表单进行选择元素最后生成一个xml文件发送到手机上，因为之前实现了xmpp发送文件的作用，所以现在只需要根据文件生成一个xml文件。中途还算顺利，两天搞定！

   最终创建xml的代码就是这一段：

void hellodialog::create_Xml()

{

    QString fileName = QFileDialog::getSaveFileName(this,"Save","",".xml");

    QFile file(fileName);

    if(!file.open(QIODevice::WriteOnly|QIODevice::Text))

    {

        return ;

    }

    QDomDocument document;

    QString strHeader( "version=\"1.0\" encoding=\"UTF-8\"" );

    document.appendChild( document.createProcessingInstruction("xml", strHeader) );

    QDomElement root_elem = document.createElement("node");

    document.appendChild(root_elem);

    QDomElement child1 = document.createElement("component");

    child1.setAttribute("type","Visualable");

    root_elem.appendChild(child1);

    QDomElement child2 = document.createElement("component");

    child2.setAttribute("type","ProxyDeform");

    root_elem.appendChild(child2);

    QString mesh ="Model:";

    mesh += fileNameMesh;

    mesh += ":clone";

    QDomElement item1 = document.createElement("attribute");

    item1.setAttribute("name","Model");

    item1.setAttribute("value",mesh);

    child1.appendChild(item1);

    QDomElement item2 = document.createElement("attribute");

    item2.setAttribute("name","Is build Tangent");

    item2.setAttribute("value",isBuildTangent);

    child1.appendChild(item2);

    QString material = "name=";

    material += comboBoxDiff;

    material += ",specular=";

    material += lineEditR;

    material += " ";

    material += lineEditG;

    material += " ";

    material += lineEditB;

    material += " ";

    material += lineEditE;

    material += ",bumpiness=";

    material += bumpiness;

    material += ",cull=";

    material += comboBoxCull;

    material += ",Texture=";

    material += diffPicture;

    QDomElement item3 = document.createElement("attribute");

    item3.setAttribute("name","MaterialName");

    item3.setAttribute("value",material);

    child1.appendChild(item3);

    QDomElement item4 = document.createElement("attribute");

    item4.setAttribute("name","Z Modify");

    item4.setAttribute("value",modifyZ);

    child1.appendChild(item4);

    QString vertex;

    vertex += "VertexProxyTable:";

    vertex += fileNameProxy;

    QDomElement item5 = document.createElement("attribute");

    item5.setAttribute("name","VertexProxyTable");

    item5.setAttribute("value",vertex);

    child2.appendChild(item5);

    QString object3D;

    object3D += "Object3D:";

    object3D += fileNameObj;

    object3D += ":clone";

    QDomElement item6 = document.createElement("attribute");

    item6.setAttribute("name","Object3D");

    item6.setAttribute("value",object3D);

    child2.appendChild(item6);

    QTextStream out( &file );

    document.save( out, 4 );

    file.close();

}

在此记录下，自己也是第一次用QT做点东西，多掌握点东西对自己总是好的，加油！
