QDockWidget初始宽度

Question

如何设置QDockWidget的初始宽度？

我已经实现了sizeHint函数，但是下一步呢？

如果您希望它的宽度与程序上次运行时的宽度相同，则应查看设置。Qt4.4文档中有一个关于如何使用设置here的示例。

我是这样做的：

void Applicotion::readSettings() {
  QSettings settings("Company Name", "Application Name");
  settings.beginGroup("LibraryDock");
  libraryDock->setFloating(settings.value("docked").toBool());
  libraryDock->resize(settings.value("size", QSize(1, 1)).toSize());
  libraryDock->move(settings.value("pos", QPoint(200, 200)).toPoint());
  addDockWidget((Qt::DockWidgetArea)settings.value("dockarea", Qt::RightDockWidgetArea).toInt(), libraryDock);
  settings.endGroup();
}

void Applicotion::writeSettings() {
  QSettings settings("Company Name", "Application Name");
  settings.beginGroup("LibraryDock");
  settings.setValue("dockarea", dockWidgetArea(libraryDock));
  settings.setValue("docked", libraryDock->isFloating());
  settings.setValue("size", libraryDock->size());
  settings.setValue("pos", libraryDock->pos());
  settings.endGroup();

}
