QT 等待对话框/进度--

用QT的,加载的一张gif图片。记录下来以后免得忘记。
[cpp]  
#ifndef DIALOG_H  
#define DIALOG_H  
  
#include <QDialog>  
#include <QLabel>  
#include<QPainter>  
#include<QMovie>  
  
class Dialog : public QDialog  
{  
    Q_OBJECT  
  
public:  
    explicit Dialog(QWidget *parent = 0);  
    ~Dialog();  
  
private:  
    QMovie *movie;  
    QLabel *label;  
};  
  
#endif // DIALOG_H  
 
[cpp]  
#include"dialog.h"  
  
Dialog::Dialog(QWidget*parent):  
    QDialog(parent)  
{  www.zzzyk.com
    label = new QLabel(this);  
    this->setFixedSize(200,200);  
    setWindowOpacity(0.5);  //设置透明用;  
    this->setWindowFlags(Qt::Dialog|Qt::CustomizeWindowHint);  
  
    //取消对话框标题  
    //this->setWindowFlags(Qt::Dialog|Qt::FramelessWindowHint);  
  
    //取消对话框标题和边框  
    //this->setAutoFillBackground(true);  
    this->setContentsMargins(0,0,0,0);  
    label->setContentsMargins(0,0,0,0);  
    /*QPalettepalette;palette.setBrush(QPalette::Background,QBrush(QPixmap("E:/qml/imgdialog/loading.gif"))); 
    this->setPalette(palette)*/;  
    movie = new QMovie("loading.gif");  
    label->setMovie(movie);  
    movie->start();  
}  
Dialog::~Dialog()  
{  
    delete label;  
    delete movie;  
}  
 
效果:
