I am using ```PyQGIS API``` for developing the standalone application to load the certain ```VectorLayers```. I used the ```QgsMapCanvas``` to load the map and ```QgsLayerTreeView``` to show the layer tree view using code below- # Layer Tree View self.layerTreeRoot = QgsProject.instance().layerTreeRoot() self.layerTreeModel = QgsLayerTreeModel(self.layerTreeRoot) self.layerTreeView = QgsLayerTreeView() self.layerTreeView.setModel(self.layerTreeModel) self.layoutWidgetLayout = QHBoxLayout() self.layoutWidgetLayout.addWidget(self.layerTreeView) self.layerWidget.setLayout(self.layoutWidgetLayout) Now I want to style the layer and change some behaviors of the style using Layer Properties. How can I get that ```LayerPropertiesWindow``` by context menu of Layer as below. [![enter image description here][1]][1] [1]: https://i.sstatic.net/rdMjJ.png
