Création d’éléments d’interface utilisateur

Substance 3D Designer inclut Qt pour Python. Les utilisateurs peuvent utiliser la classe UI Managerpour créer des menus, des boîtes de dialogue, des panneaux personnalisés et d’autres éléments d’interface utilisateur pour leurs plug-ins.

Sur cette page, vous trouverez des exemples simples d’utilisation de Qt pour Python dans Designer.

Pour plus d’informations sur Qt pour Python, consultez la documentation officielle.

Création de boîtes de dialogue

import sd

from PySide2 import QtWidgets



## Get the application and the UI Manager.

app = sd.getContext().getSDApplication()

uiMgr = app.getQtForPythonUIMgr()



## Create a new dialog. For shortcuts to work correctly

## it is important to parent the new dialog to Designer's main window.

mainWindow = uiMgr.getMainWindow()

dialog = QtWidgets.QDialog(parent=mainWindow)



## Create a layout and some widgets.

layout = QtWidgets.QVBoxLayout()

layout.addWidget(QtWidgets.QPushButton("Press Me"))

dialog.setLayout(layout)



## Show the dialog (non-modal).

dialog.show()

Création de menus

import sd

from PySide2 import QtWidgets



## Get the application and the UI Manager.

app = sd.getContext().getSDApplication()

uiMgr = app.getQtForPythonUIMgr()



## Function that will be called when our menu item is selected.

def sayHello():

 print("Hello!")



## Create a new menu.

menu = uiMgr.newMenu(menuTitle="MyMenu", objectName="doc.example.my_menu")

## Create a new action.

act = QtWidgets.QAction("Hello", menu)

act.triggered.connect(sayHello)



## Add the action to the menu.

menu.addAction(act)

Création de panneaux

import sd

from PySide2 import QtWidgets



## Get the application and the UI Manager.

app = sd.getContext().getSDApplication()

uiMgr = app.getQtForPythonUIMgr()



## Create a new dock widget.

## The dock identifier is used when saving and restoring dock positions and sizes.

## For this reason, it's important that the identifier is unique.

dock = uiMgr.newDockWidget(identifier="sample.test.dock", title="New Dock")



## Create a layout and add some widgets.

layout = QtWidgets.QVBoxLayout()

dock.setLayout(layout)



for i in range(0, 5):

 layout.addWidget(QtWidgets.QPushButton("Button %s" % i))

Création de barres d’outils dans la fenêtre de l’application

import sd

from PySide2 import QtCore, QtWidgets



## Get the application and the UI Manager.

app = sd.getContext().getSDApplication()

uiMgr = app.getQtForPythonUIMgr()



## Get Designer's main window.

mainWindow = uiMgr.getMainWindow()



## Create our toolbar.

toolbar = QtWidgets.QToolBar()

toolbar.addAction("Tool")

toolbar.addAction("Bar")



## Add our toolbar to Designer's window.

mainWindow.addToolBar(QtCore.Qt.TopToolBarArea, toolbar)

Création de barres d’outils dans Vue du graphe

from functools import partial

import sd



from PySide2 import QtCore, QtGui, QtWidgets



class MyGraphToolBar(QtWidgets.QToolBar):

    def __init__(self, graphViewID, uiMgr):

        super(MyGraphToolBar, self).__init__(parent=uiMgr.getMainWindow())



## Save the graphViewID and uiMgr for later use.

        self.__graphViewID = graphViewID

        self.__uiMgr = uiMgr



## Add actions to our toolbar.

        act = self.addAction("P")

        act.setToolTip("Print the selected nodes to the Python console")

        act.triggered.connect(self.__onPrintNodes)



    def __onPrintNodes(self):

        for node in self.__getSelectedNodes():

            print(node)



    def __getSelectedNodes(self):

## Use our saved graphViewID to retrieve the graph selection.

        return self.__uiMgr.getGraphSelectedNodesFromGraphViewID(

            self.__graphViewID)



def onNewGraphViewCreated(graphViewID, uiMgr):

## Create our toolbar.

    toolbar = MyGraphToolBar(graphViewID, uiMgr)



## Add our toolbar to the graph widget.

    uiMgr.addToolbarToGraphView(

        graphViewID,

        toolbar,

        icon = None,

        tooltip = "My Graph Toolbar")



## Get the application and UI manager object.

ctx = sd.getContext()

app = ctx.getSDApplication()

uiMgr = app.getQtForPythonUIMgr()



## Register a callback to know when GraphViews are created.

uiMgr.registerGraphViewCreatedCallback(

    partial(onNewGraphViewCreated, uiMgr=uiMgr))

## Save the graphViewID and uiMgr for later use.

        self.__graphViewID = graphViewID

        self.__uiMgr = uiMgr



## Set up the action.

        self.setText("P")

        self.setToolTip("Print the selected nodes to the Python console")

## Create our action.

    action = MyGraphAction(

        graphViewID = graphViewID,

    )



## Add our action to the graph toolbar.

    uiMgr.addActionToGraphViewToolbar(

## Get the application and UI manager object.

ctx = sd.getContext()

## Register a callback to know when GraphViews are created.

uiMgr.registerGraphViewCreatedCallback(
