将 VTK window 加载到 PyQT Window 时出现问题
Problem loading VTK window into PyQT Window
VTK 和 PyQt4 的问题让我焦头烂额。我有一个界面，里面有两个选项卡，一个是 VTK window，另一个是图表。
ui_Test设置界面的代码如下：
# -*- coding: utf-8 -*-
from PyQt4 import QtCore, QtGui
try:
_fromUtf8 = QtCore.QString.fromUtf8
except AttributeError:
def _fromUtf8(s):
return s
try:
_encoding = QtGui.QApplication.UnicodeUTF8
def _translate(context, text, disambig):
return QtGui.QApplication.translate(context, text, disambig, _encoding)
except AttributeError:
def _translate(context, text, disambig):
return QtGui.QApplication.translate(context, text, disambig)
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName(_fromUtf8("MainWindow"))
MainWindow.resize(800, 600)
self.centralwidget = QtGui.QWidget(MainWindow)
self.centralwidget.setObjectName(_fromUtf8("centralwidget"))
self.gridLayout = QtGui.QGridLayout(self.centralwidget)
self.gridLayout.setObjectName(_fromUtf8("gridLayout"))
self.verticalLayout = QtGui.QVBoxLayout()
self.verticalLayout.setObjectName(_fromUtf8("verticalLayout"))
self.tabWidget = QtGui.QTabWidget(self.centralwidget)
self.tabWidget.setObjectName(_fromUtf8("tabWidget"))
self.tab = QtGui.QWidget()
self.tab.setObjectName(_fromUtf8("tab"))
self.gridLayout_2 = QtGui.QGridLayout(self.tab)
self.gridLayout_2.setObjectName(_fromUtf8("gridLayout_2"))
self.vtkLayout = QtGui.QVBoxLayout()
self.vtkLayout.setObjectName(_fromUtf8("vtkLayout"))
self.gridLayout_2.addLayout(self.vtkLayout, 0, 0, 1, 1)
self.tabWidget.addTab(self.tab, _fromUtf8(""))
self.tab_2 = QtGui.QWidget()
self.tab_2.setObjectName(_fromUtf8("tab_2"))
self.tabWidget.addTab(self.tab_2, _fromUtf8(""))
self.verticalLayout.addWidget(self.tabWidget)
self.gridLayout.addLayout(self.verticalLayout, 0, 0, 1, 1)
MainWindow.setCentralWidget(self.centralwidget)
self.menubar = QtGui.QMenuBar(MainWindow)
self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 31))
self.menubar.setObjectName(_fromUtf8("menubar"))
MainWindow.setMenuBar(self.menubar)
self.statusbar = QtGui.QStatusBar(MainWindow)
self.statusbar.setObjectName(_fromUtf8("statusbar"))
MainWindow.setStatusBar(self.statusbar)
self.retranslateUi(MainWindow)
self.tabWidget.setCurrentIndex(0)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
def retranslateUi(self, MainWindow):
MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow", None))
self.tabWidget.setTabText(self.tabWidget.indexOf(self.tab), _translate("MainWindow", "Tab 1", None))
self.tabWidget.setTabText(self.tabWidget.indexOf(self.tab_2), _translate("MainWindow", "Tab 2", None))
if __name__ == "__main__":
import sys
app = QtGui.QApplication(sys.argv)
MainWindow = QtGui.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())
而主要的 window 代码是：
#!/usr/bin/env python
import sys
from vtk import vtkSphereSource,vtkRenderer,vtkColorTransferFunction,vtkPoints,vtkCellArray,vtkUnsignedCharArray,vtkPolygon,vtkPolyData,VTK_MAJOR_VERSION,vtkPolyDataMapper,vtkActor,vtkProperty,vtkScalarBarActor
from PyQt4 import QtCore, QtGui
from vtk.qt4.QVTKRenderWindowInteractor import QVTKRenderWindowInteractor
import ui_Test
class MainWindow(QtGui.QMainWindow,ui_Test.Ui_MainWindow):
def __init__(self, parent = None):
QtGui.QMainWindow.__init__(self, parent)
self.setupUi(self)
self.vtkWidget = QVTKRenderWindowInteractor(self)
self.vtkLayout.addWidget(self.vtkWidget)
self.ren = vtkRenderer()
self.vtkWidget.GetRenderWindow().AddRenderer(self.ren)
self.iren = self.vtkWidget.GetRenderWindow().GetInteractor()
# Create source
source = vtkSphereSource()
source.SetCenter(0, 0, 0)
source.SetRadius(5.0)
# Create a mapper
mapper = vtkPolyDataMapper()
mapper.SetInputConnection(source.GetOutputPort())
# Create an actor
actor = vtkActor()
actor.SetMapper(mapper)
self.ren.AddActor(actor)
self.ren.ResetCamera()
self.iren.Initialize()
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
window = MainWindow()
window.show()
sys.exit(app.exec_())
问题是，当这个 运行s 它通过 VTK 错误日志 window 中的错误时，选项卡上没有任何显示。错误看起来像这样：
错误：在 C:\VPP\standalone-build\VTK-source\Rendering\OpenGL2\vtkShaderProgram.cxx 中，第 431 行
vtkShaderProgram (0000016142650060):
错误：在 C:\VPP\standalone-build\VTK-source\Rendering\OpenGL2\vtkWin32OpenGLRenderWindow.cxx 中，第 769 行
vtkWin32OpenGLRenderWindow (00000161425DD820): 未能获得有效的像素格式。
错误：在 C:\VPP\standalone-build\VTK-source\Rendering\OpenGL2\vtkOpenGLRenderWindow.cxx 中，第 785 行
vtkWin32OpenGLRenderWindow (00000161425DD820): GLEW 无法初始化。

vtkShaderProgram (0000016142650060): 1: #version 120
我不会 post 完整的东西，因为它真的很长！我可以制作 PyQT VTK 示例 运行，因此 VTK/PyQT 版本不是问题 - 我认为这与我将其添加到选项卡的方式有关。任何帮助将不胜感激！
抱歉，我正在使用 PyQt5，一切正常。
