I'm tearing my hair out with a problem with VTK and PyQt4. I have an interface that has two tabs in it, one will house the VTK window and the other graphs.
The code for ui_Test which sets up the interface is as follows:
# -*- coding: utf-8 -*-

self.verticalLayout.setObjectName(_fromUtf8("verticalLayout"))

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_())
And the main window code is:
#!/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_())
The problem is that when this runs it throughs errors in the VTK error log window and nothing shows on the tab. The error looks something like this:
ERROR: In C:\VPP\standalone-build\VTK-source\Rendering\OpenGL2\vtkShaderProgram.cxx, line 431
vtkShaderProgram (0000016142650060):
ERROR: In C:\VPP\standalone-build\VTK-source\Rendering\OpenGL2\vtkWin32OpenGLRenderWindow.cxx, line 769

vtkShaderProgram (0000016142650060): 1: #version 120
I won't post the full thing as it is really long! I can make the PyQT VTK examples run so the VTK/PyQT version isn't the problem - I assume it is to do with how I'm adding it to the tab. Any help will be massively appreciated!
Sorry, I'm using PyQt5, everything works without problems.

I designed a window with QtDesigner and added a scrollarea and a layout in it, but the scroll area doesn't scroll, it shows the scroll bar but It cant be scrolled at all.

Sir, your code is a bit messed.
Here is a small example, see if it works. There is no secret. :D
it's in PyQt5. You just gotta change your imports to PyQt4.

OBS: You will just have to change for QPushButtons, QLabels,... instead of small QWidgets and whatever you need.
I'm trying to connect a push-button on my main window to open a new widget when I click it. But each time I run the program I get this error:
AttributeError: 'dataAcquisition' object has no attribute 'gpioButton'
I will be grateful if someone can help.

You created a separate namespace for the ui, so you would need to access the button like this:
self.ui.gpioButton.clicked.connect(self.gpioButton_clicked)
However, if you'd prefer to have all the widgets as attributes of the window, do this:
class gpioDialog(QtGui.QDialog, Ui_GPIODialog):
def __init__(self, parent=None):
super(gpioDialog, self).__init__(parent)
flags = QtCore.Qt.Drawer | QtCore.Qt.WindowStaysOnTopHint
self.setWindowFlags(flags)

super(dataAcquisition, self).__init__(parent)
self.setupUi(self)
self.gpioButton.clicked.connect(self.gpioButton_clicked)
self.popGPIO = gpioDialog()
I am trying to recreate some pyqt codes using qt designer.I generated a simple python code using pyuic4.The image should load only in the QgraphicView area but it covers the entire window and I could not see the push buttons.

self.label.setText(_translate("MainWindow", "close", None))
self.label_2.setText(_translate("MainWindow", "view", None))
Now I need to add action to label and label_2. How to make the label to perform closeapp()?
Add a function to Ui_MainWindow class (untitled.py)
def click(self,eve):
print "clicked"
Then add attribute to label object
self.label.mousePressEvent = self.click
another option is just modify run.py file like following
class ExampleApp(QtGui.QMainWindow, untitled.Ui_MainWindow):
def click(self,eve):
print "clicked"
def __init__(self):
super(self.__class__, self).__init__()
self.setupUi(self)
self.label.mousePressEvent = self.click
self.setWindowFlags(QtCore.Qt.FramelessWindowHint)
QLabel inherits QWidget. QWidget` has an event handler mousePressEvent
so as E-ebola virus mentioned
add
self.label.mousePressEvent = self.click
and define
def click(self,event):
#do something
or
subclass QLabel
class customLabel(QLabel):
def __init__(self):
QLabel.__init__(self)
def self.mousePressEvent(self,event):
self.emit(SIGNAL("closeapp"))
emit a SIGNAL when label is pressed, i would implement it as
self.label = customLabel()
self.connect(self.label,SIGNAL('closeapp'),self.close)
im beginner in Pyqt4.So, i need a help. I had do a multiple widget in Pyqt designer, so i want to connect my main window to my widget. In my main menu, there's a enter button and i want when i clicked the enter button, it will go to page2.ui Here is my code

I hope you guys can help me . Thanks
i wouldn't recommend you to continue the way you're going even the error message at the top warns you that changes in the auto-generate file would be lost if you regenerate it again. you should seperate your Ui file and your main code

as i said earlier your code is not structured properly, if it was it would be as easy as calling self.hide(), or self.close but your Ui_MainWindow is not a QWidget or QMainWindow so it dosen't have that method the QMainWindow is constructed outside the class so you don't have access to it. with some hacking around it can be fixed but it's not good practice. i'll suggest you look at the git repo https://github.com/shuge/Qt-Python-Binding-Examples and see how to organize your code. ideally the auto-generated ui file should be seperated from your logic...This makes it easier to modify your logic in future without messing up the ui or losing your changes when you generate the ui again
ideally you should inherit from QtGui.QMainWindow or some sort of widget
