dockwidgetsの位置とサイズを保存して復元する

Question

保存と復元がどのように動作するのかよくわからないので、アプリケーションを閉じて再度開くと、ドックウィジェットのジオメトリを保存することができます。私は5つのドックウィジェットを持っていますが、私はこの機能を持っていたいと思います。

restoreStateとsaveStateの両方をinitとcloseにそれぞれ使用する必要があると仮定します。しかし、どうすれば設定できますか？

メイン・ウィンドウクラス

import sys 
from PyQt4.QtCore import * 
from PyQt4.QtGui import * 
from DockWindowGraph import Dock 

class Window(QMainWindow): 
    def __init__(self, parent=None): 
     super(Window, self).__init__(parent) 

     self.centralWindow_ = QFrame() 
     self.setCentralWidget(None) 

     self.CreateWidgets() 

     self.settings = QSettings() 
     self.restoreState() 

    def CreateWidgets(self):   
     self.toolbar = self.addToolBar('Toolbar') 
     self.toolbar.setMovable(False)  

     exitA = QAction(QIcon('Images/gj.png'), 'Exit', self) 
     exitA.setShortcut('Ctrl+Q') 
     exitA.setStatusTip('Exit application') 
     exitA.triggered.connect(self.close) 
     self.toolbar.addAction(exitA) 

     openDock_ = QAction(QIcon('Images/gj.png'), 'Open', self) 
     openDock_.setShortcut('Ctrl+E') 
     openDock_.setStatusTip('Open Dock') 
     openDock_.triggered.connect(self.OpenDockWindow) 
     self.toolbar.addAction(openDock_) 

     self.setWindowTitle("We do not sow") 
     self.showFullScreen() 

     self.firstDock_ = Dock(self, 'First') 
     self.firstDock_.setObjectName('First') 
     self.addDockWidget(Qt.LeftDockWidgetArea, self.firstDock_)  

     self.secondDock_ = Dock(self, 'Second') 
     self.firstDock_.setObjectName('Second') 
     self.addDockWidget(Qt.LeftDockWidgetArea, self.secondDock_) 

     self.thirdDock_ = Dock(self, 'Third') 
     self.thirdDock_.setObjectName('Third') 
     self.splitDockWidget(self.firstDock_, self.thirdDock_, Qt.Horizontal) 

     self.fDock_ = Dock(self, 'Fourth') 
     self.fDock_.setObjectName('Fourth') 
     self.splitDockWidget(self.firstDock_, self.fDock_, Qt.Horizontal) 

     self.fiDock_ = Dock(self, 'Fifth') 
     self.fiDock_.setObjectName('Fifth') 
     self.splitDockWidget(self.firstDock_, self.fiDock_, Qt.Vertical) 

     self.setTabPosition(Qt.AllDockWidgetAreas, QTabWidget.North) 

    def OpenDockWindow(self): 
     dock_ = Dock((self.frameGeometry().width()/2), self.firstDock_) 

     self.addDockWidget(Qt.RightDockWidgetArea, dock_) 
     self.tabifyDockWidget(self.secondDock_, dock_) 

    def closeEvent(self, event): 
     print('closing') 

     settings_ = QSettings() 
     self.saveState() 


app = QApplication(sys.argv) 
app.setOrganizationDomain('ltd') 
app.setOrganizationName('Alg') 
w = Window() 
sys.exit(app.exec_()) 

私のドッククラス：

from PyQt4.QtCore import * 
from PyQt4.QtGui import * 
from DockWindowFrame import Frame 

class Dock(QDockWidget): 
    def __init__(self, title, parent=None): 
     super(Dock, self).__init__(parent) 

     self.setAllowedAreas(Qt.RightDockWidgetArea | Qt.LeftDockWidgetArea | Qt.TopDockWidgetArea | Qt.BottomDockWidgetArea) 
     self.setFeatures(QDockWidget.DockWidgetFloatable | QDockWidget.DockWidgetMovable) 

     self.frame = Frame() 
     self.frame.setStyleSheet("QWidget { background-color: rgba(0,220,0,100%)}") 
     self.setWidget(self.frame) 

    def ReturnFrame(self): 
     return self.frame 

EDIT：答えの下にしようとした後にエラーが発生しました。

これは、ここに動作します：

def __init__(self): 
    self.readSettings() 

def closeEvent(self, event): 
    print('closing') 
    settings = QSettings() 
    settings.setValue('geometry',self.saveGeometry()) 
    settings.setValue('windowState',self.saveState()) 
    super(Window, self).closeEvent(event) 

def readSettings(self): 
    settings = QSettings() 
    self.restoreGeometry(settings.value("geometry").toByteArray()) 
    self.restoreState(settings.value("windowState").toByteArray()) 

参考： QMainWindow.saveState() QMainWindow.restoreState()
