[I reproduced this on Windows, but have not tested other platforms]
Showing a tooltip can raise its parent window, taking the topmost window away from the user.
With the testcase below:
1. Start with the 'other widget' partially obscuring the 'tooltip widget'.
2. Click the 'other widget'.
3. Move the mouse onto the 'tooltip widget'
Result: The 'tooltip widget' is raised, partially or fully obscuring the 'other widget'. However, the 'other widget' is still treated by the windowing system as active. Clicking on the 'other widget' now does not raise it above the 'tooltip widget'.
#include <QApplication> #include <QEnterEvent> #include <QToolTip> class MyWidget : public QWidget { Q_OBJECT public: void enterEvent(QEvent *event) override { QToolTip::showText(static_cast<QEnterEvent*>(event)->screenPos().toPoint(), "This is the message", this); QWidget::enterEvent(event); } }; int main(int argc, char** argv) { QApplication app(argc, argv); QWidget otherWidget; otherWidget.setWindowTitle("Other widget"); otherWidget.show(); otherWidget.resize(300, 300); MyWidget mw; mw.setWindowTitle("Tooltip widget"); mw.show(); return app.exec(); } #include "tooltip.moc"
