Qt里使用QSplashScreen类制作Splash启动窗口

Question

[代码] cpp代码

1. #include <QtGui/QtGui>
2. #include <QtGui/QPixmap>
3. #include <QtGui/QSplashScreen>
4. #include "ui_browser.h"
6. int main(int argc, char **argv)
7. {
8.   QApplication app(argc, argv);
10.   QPixmap pixmap("splash.png");
11.     QSplashScreen *splash = new QSplashScreen(pixmap);
12.     splash->show();
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();
20.   splash->finish(form);
21.     delete splash;
23.   return app.exec();
24. }

复制代码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"
6. int main(int argc, char **argv)
7. {
8.   QApplication app(argc, argv);
10.   QDialog dialog;
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"));
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();
23.   return app.exec();
24. }
