XML文档的读写

一个根节点，下面每一个子节点代表一个子程序，内容为子程序名字，图标路径，exe路径

/*

* 读取XML配置文档

*/

static int count_flag = 0;

void MainWindow::read_XML()

{

QFile file("./subroutine/config.xml"); //引用文件路径

if(!file.open((QFile::ReadOnly | QFile::Text))) //只读文本方式打开

{

QMessageBox::information(NULL,"Title","OpenFile false"); //如果打开失败则提示

}

/*

* 装在XML文件内容到内存

*/

QDomDocument doc;

doc.setContent(&file);

file.close();

QDomElement root = doc.documentElement();

QDomNode node = root.firstChild();

QString name = "asd";

QString iconpath;

QString exepath;

while (!node.isNull())

{

QDomElement element = node.toElement();

if(!element.isNull())

{

QDomNamedNodeMap list = element.attributes();

for(int i = 0;i

{

if(list.item(i).nodeName() == "name")

{

name = list.item(i).nodeValue();

}

else if (list.item(i).nodeName() == "iconpath")

{

iconpath = list.item(i).nodeValue();

}

else if (list.item(i).nodeName() == "exepath")

{

exepath = list.item(i).nodeValue();

}

}

}

// QPushButton *button = new QPushButton(name, this);

// button->setIcon(QIcon(iconpath));

// button->show();

// connect(button,&QPushButton::clicked,[=]()

// {

// QProcess *myProcess = new QProcess(this);

// myProcess->startDetached(exepath);

// });

MPushButton *button = new MPushButton(this);

button->set_name(name);

button->set_ICON(iconpath);

button->show();

connect(button,&MPushButton::clicked,[=]()

{

QProcess *myProcess = new QProcess(this);

myProcess->startDetached(exepath);

});

flowLayout->addWidget(button);

node = node.nextSibling();

count_flag++;

if(count_flag-35>0)

{

showWidgt->setGeometry(0,0,ui->widget_main->width(),ui->widget_main->height()+100*((count_flag-35)/7+1));

}

}

}

以上代码为读取XML部分，
