Fullscreen widget

c++linuxqtwidgetfullscreen

提问by Max Frai

How can I make my widget fullscreen? I've tried something like this:

如何使我的小部件全屏显示?我试过这样的事情:

void MainWindow::SetFullScreen()
{
    // Make our window without panels
    this->setWindowFlags( Qt::FramelessWindowHint | Qt::Tool | Qt::WindowStaysOnTopHint );
    // Resize refer to desktop
    this->resize( QApplication::desktop()->size() );

    this->setFocusPolicy( Qt::StrongFocus );
    this->setAttribute(Qt::WA_QuitOnClose, true);

    qApp->processEvents();
    show();
    this->setFocus();
}

But widget isn't over system panels. Any another ideas?

但是小部件不在系统面板上。还有其他想法吗?

QWidget::showFullScreen()is what you need - works great under Linux+Windows in my projects for years - but be careful, there shouldn't be two calls of this function (eg. first call of QMainWindo->showFullScreen()and then MyWidget->showFullScreen()).

QWidget::showFullScreen()是您所需要的 - 在我的项目中在 Linux+Windows 下运行良好多年 - 但要小心,不应有两次调用此函数(例如,第一次调用 ,QMainWindo->showFullScreen()然后MyWidget->showFullScreen())。

This code will allow you to set a full screen by double clicking and to return back to the normal view by double clicking again.

此代码将允许您通过双击设置全屏,并通过再次双击返回到正常视图。

void myWidget::mouseDoubleClickEvent(QMouseEvent *e) {
  QWidget::mouseDoubleClickEvent(e);
  if(isFullScreen()) {
     this->setWindowState(Qt::WindowMaximized);
  } else {
     this->setWindowState(Qt::WindowFullScreen);
  }
}
