问题描述
如何在 Qt 中正确实现最小化到托盘"功能?
How do I properly implement a "minimize to tray" function in Qt?
我在 QMainWindow::changeEvent(QEvent *e) 中尝试了以下代码，但窗口只是最小化到任务栏，并且在恢复时客户区显示为空白.
I tried the following code inside QMainWindow::changeEvent(QEvent *e), but the window simply minimizes to the taskbar and the client area appears blank white when restored.
if (Preferences::instance().minimizeToTray())
{
e->ignore();
this->setVisible(false);
}
试图忽略该事件似乎也无济于事.
Attempting to ignore the event doesn't seem to do anything, either.
推荐答案
显然处理其他事件需要一点延迟(也许有人会发布确切的细节?).这是我最终做的，效果很好:
Apparently a small delay is needed to process other events (perhaps someone will post the exact details?). Here's what I ended up doing, which works perfectly:
void MainWindow::changeEvent(QEvent* e)
{
switch (e->type())
{
case QEvent::LanguageChange:
this->ui->retranslateUi(this);
break;
case QEvent::WindowStateChange:
{
if (this->windowState() & Qt::WindowMinimized)
{
if (Preferences::instance().minimizeToTray())
{
QTimer::singleShot(250, this, SLOT(hide()));
}
}
break;
}
default:
break;
}
QMainWindow::changeEvent(e);
}
