Question

我是设计GUI和Python的新手

我试图在用QTDesign制作的简单GUI中显示渲染，但是没有正确显示。

渲染有效，但我希望渲染小部件位于主内部窗口（或任何其他窗口小部件？）但不起作用。

有人知道怎么做吗？

问候！全型

用户界面：

    from PySide import QtCore, QtGui

    class Ui_MainWindow(object):
        def setupUi(self, MainWindow):
            MainWindow.setObjectName("MainWindow")
            MainWindow.resize(455, 380)
            MainWindow.setMinimumSize(QtCore.QSize(455, 380))
            MainWindow.setMaximumSize(QtCore.QSize(455, 380))
            self.centralwidget = QtGui.QWidget(MainWindow)
            self.centralwidget.setObjectName("centralwidget")
            self.pushButton = QtGui.QPushButton(self.centralwidget)
            self.pushButton.setGeometry(QtCore.QRect(365, 340, 75, 23))
            self.pushButton.setObjectName("pushButton")

            self.frame = QtGui.QFrame(self.centralwidget)
            self.frame.setGeometry(QtCore.QRect(20, 20, 416, 306))
            self.frame.setFrameShape(QtGui.QFrame.StyledPanel)
            self.frame.setFrameShadow(QtGui.QFrame.Raised)
            self.frame.setObjectName("frame")

            MainWindow.setCentralWidget(self.centralwidget)

            self.retranslateUi(MainWindow)
            QtCore.QMetaObject.connectSlotsByName(MainWindow)

        def retranslateUi(self, MainWindow):
            MainWindow.setWindowTitle(QtGui.QApplication.translate("MainWindow", "MainWindow", None, QtGui.QApplication.UnicodeUTF8))
            self.pushButton.setText(QtGui.QApplication.translate("MainWindow", "PushButton", None, QtGui.QApplication.UnicodeUTF8))

        #Set actors and mappers, then instead of creating a renderwindowinteractor,
        #use the self.ui.meshDisplayWidget to display the mesh. Also define picker, and
        #set data source (for code about displaying a mesh from coordinates, as
        #an unstructured grid.

你看到这个例子了吗？它适用于我为PyQt交换PySide。 http://www.vtk.org/Wiki/VTK/Examples/Python/Widgets/EmbedPyQt

Answer 2

要在Widget内部渲染，请使用QVTKRenderWindowInteractor类。首先，进入这里：

https://svn.enthought.com/enthought/browser/Mayavi/trunk/enthought/tvtk/pyface/ui/qt4/QVTKRenderWindowInteractor.py?rev=20906

你可以做两件事。

第一个选项：

一个。像往常一样创建Qt窗口。

湾创建一个QVTKRenderWindowInteractor实例，并将其父级设置为要包含它的小部件/窗口。

self.myViewer= QVTKRenderWindowInteractor(self.parentWidget)

QVTKRenderWindowInteractor是vtkRenderWindowInteractor的包装器，你可以得到这样的渲染窗口：

self.myViewer.GetRenderWindow()

第二个选项：

您可以使用QtDesigner将您的小部件宣传为QVTKRenderWindowInteractor

使用Pyside - VTK和QVTKRenderWindowInteractor
