Qt里使用QSplashScreen类制作Splash启动窗口

阳光boyer

[代码] cpp代码

1. #include <QtGui/QtGui>
   
2. #include <QtGui/QPixmap>
   
3. #include <QtGui/QSplashScreen>
   
4. #include "ui_browser.h"
   
5. 
   
6. int main(int argc, char **argv)
   
7. {
   
8.   QApplication app(argc, argv);
   
9. 
   
10.   QPixmap pixmap("splash.png");
    
11.     QSplashScreen *splash = new QSplashScreen(pixmap);
    
12.     splash->show();
    
13. 
    
14.   QMainWindow *form = new QMainWindow;
    
15.   Ui::MainWindow ui;
    
16.   ui.setupUi(form);
    
17.   ui.textBrowser->setSource(QString("files:///C:/Qt/4.1.2/doc/html/index.html"));
    
18.   form->show();
    
19. 
    
20.   splash->finish(form);
    
21.     delete splash;
    
22. 
    
23.   return app.exec();
    
24. }

而采用计时器来控制显示时间的话，可用下面方法自己制作SplashWindow：

1. #include <QtGui/QtGui>
   
2. #include <QtGui/QDialog>
   
3. #include <QtCore/QTimer>
   
4. #include "ui_browser.h"
   
5. 
   
6. int main(int argc, char **argv)
   
7. {
   
8.   QApplication app(argc, argv);
   
9. 
   
10.   QDialog dialog;
    
11. 
    
12.   QMainWindow *form = new QMainWindow;
    
13.   Ui::MainWindow ui;
    
14.   ui.setupUi(form);
    
15.   ui.textBrowser->setSource(QString("files:///C:/Qt/4.1.2/doc/html/index.html"));
    
16. 
    
17.   QTimer timer;
    
18.   QObject::connect(&timer, SIGNAL(timeout()), form, SLOT(show()));
    
19.   QObject::connect(&timer, SIGNAL(timeout()), &dialog, SLOT(accept()));
    
20.   timer.start(10000);
    
21.   dialog.exec();
    
22. 
    
23.   return app.exec();
    
24. }
