XML文件的读写


Qt 利用XML文档,写一个程序集合 二_ico

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<list.count();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,
