我有一个QSplashScreen
通过一堆图像运行的制作,类似于 gif,并在主窗口打开时关闭。这在 Windows 上运行良好,但是当我在 mac 上运行它时,它变得很时髦。而不是在浏览完所有图片时关闭,就像它应该在单击时以相反的顺序开始浏览图像一样。
这是标题(splashscreen.h):
class SplashScreen : public QObject
{
Q_OBJECT
public:
explicit SplashScreen(QObject *parent = 0);
private:
QString filename0;
QString filename1;
QString filename;
int frameNum;
Qt::WindowFlags flags;
private slots:
void showFrame(void);
};
这是实现(splashscreen.cpp):
SplashScreen::SplashScreen(QObject *parent) :
QObject(parent)
{
QTimer *timer = new QTimer;
timer->singleShot(0, this, SLOT(showFrame()));
frameNum = 0;
}
void SplashScreen::showFrame(void)
{
QSplashScreen *splash = new QSplashScreen;
QTimer *timer = new QTimer;
frameNum++;
QString filename0 = ""; //first and second half of file path
QString filename1 = "";
splash->showMessage("message here", Qt::AlignBottom, Qt::black);
filename = filename0 + QString::number(frameNum) +filename1; // the number for the file is added here
splash->setPixmap(QPixmap(filename)); // then shown in the splashscreen
splash->show();
if (frameNum < 90)
{
timer->singleShot(75, this, SLOT(showFrame()));
}
else if (frameNum == 90)
{
splash->close();
flags |= Qt::WindowStaysOnBottomHint;
return;
}
}
这是主文件(main.cpp):
int main(int argc, char *argv[])
{
Application app(argc, argv);
SplashScreen *splash = new SplashScreen;
QSplashScreen *splashy = new QSplashScreen;
View view; //main window
QTimer::singleShot(10000, splashy, SLOT(close()));
splashy->hide();
QTimer::singleShot(10000, &view, SLOT(show()));
return app.exec();
}
我有几种不同的方法来关闭启动画面,但它们似乎都不起作用。这是mac中的错误还是我可以在我的代码中修复什么?
