Creación de elementos de interfaz de usuario

Substance 3D Designer incluye Qt Para Python. Los usuarios pueden usar la clase UI Managerpara crear menús, cuadros de diálogo, paneles personalizados y otros elementos de la interfaz de usuario para sus complementos.

En esta página encontrará ejemplos sencillos de cómo utilizar Qt para Python en Designer.

Para obtener más información sobre Qt para Python, consulte la documentación oficial.

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()

Creación de menús

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)

Creación de paneles

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))

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)

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))
