Qt 注册表

一、写入注册表

void MainWindow::writeSettings()
{
QSettings settings("Software Inc.", "Spreadsheet");

settings.setValue("geometry", saveGeometry());
settings.setValue("recentFiles", recentFiles);
settings.setValue("showGrid", showGridAction->isChecked());
settings.setValue("autoRecalc", autoRecalcAction->isChecked());
}

二、读入注册表

void MainWindow::readSettings()
{
QSettings settings("Software Inc.", "Spreadsheet");

restoreGeometry(settings.value("geometry").toByteArray());

recentFiles = settings.value("recentFiles").toStringList();
bool showGrid = settings.value("showGrid", true).toBool();
bool autoRecalc = settings.value("autoRecalc", true).toBool();
}
