[QGIS-Developer] How to restore dock widget plugin size after relaunch of QGIS?

[Jean-Baptiste Peter]

Thanks, adding .setObjectName() in the constructor of the dock widget subclass worked to restore the dimension of the widget. However, the dock widget does not show automatically at QGIS startup even if it was open during the last session. What is the proper way to achieve this?

 Here is the code that I'm using to initialize and run the dock widget:


    def initGui(self):
        """Create the menu entries and toolbar icons inside the QGIS GUI."""
        
        self.log("init")
        
        icon_path = ':/plugins/layout_panel/icon.png'
        self.add_action(
            icon_path,
            text=self.tr(u'Layout Panel'),
            callback=self.run,
            parent=self.iface.mainWindow())
                
        if self.dockwidget == None:
            self.dockwidget = LayoutPanelDockWidget(self.iface, self.iface.mainWindow())
            
        self.dockwidget.closingPlugin.connect(self.onClosePlugin)
        self.iface.addDockWidget(Qt.LeftDockWidgetArea, self.dockwidget)
              

    def onClosePlugin(self):
        """Cleanup necessary items here when plugin dockwidget is closed"""
        self.pluginIsActive = False


    def unload(self):
        """Removes the plugin menu item and icon from QGIS GUI."""

        for action in self.actions:
            self.iface.removePluginMenu(
                self.tr(u'&Layout Panel'),
                action)
            self.iface.removeToolBarIcon(action)
        # remove the toolbar
        del self.toolbar


    def run(self):
        """Run method that loads and starts the plugin"""
        if not self.pluginIsActive:
            self.pluginIsActive = True
            self.dockwidget.show()


Thank you!

Best,

Try calling .setObjectName() in the constructor of your dock widget subclass. That's required for the standard QGIS dock arrangement save/restore code to work correctly. (That's all that's needed -- you don't need to manually do any calls to saveGeometry/restoreGeometry).

Also I suggest using the QgsDockWidget subclass as the base class for your widget, as it has some extra niceness added on top of the standard Qt QDockWidget class.

However, the dimensions of the widget is not saved and I am not able to figure out how to restore the width and height of the widget. I tried to use QDockWidget::restoreGeometry without success. Could someone please point me how to achieve this? Thanks!
