QT Linux和Windows快捷方式不一致的问题
一、在Linux下，redo快捷方式和Windows不一致的问题
QKeySequence定义了许多｛QKeySequence:：StandardKey｝，某个操作可能在不同平台下的快捷方式是不同的，比如Redo（重新实现你的操作），在windows下是Ctrl + Y，在linux下是Ctrl + Shift + Z，如果linux下某个控件也想实现和windows一样的快捷方式，可以在代码中监听键盘事件，手动执行redo操作
bool MainWindow::eventFilter( QObject *o, QEvent *e )
{
#ifdef Q_OS_LINUX
QKeyEvent *ke = static_cast<QKeyEvent*>(e);
if (ke && ke->modifiers() == Qt::ControlModifier && ke->key() == Qt::Key_Y && o == m_pTextEdit)
{
if (!m_pTextEdit->isReadOnly())
m_pTextEdit->redo();
}
#endif
return QWidget::eventFilter(o,e);
}
