I need your help with my app. I undecorated python gui and now i need to create clicable label.

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)

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.
Here's my code:

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)

self.gpioOKButton.clicked.connect(self.acceptOKButtonClicked)
class dataAcquisition(QtGui.QMainWindow, Ui_MainWindow):
def __init__(self, parent=None):
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.

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

MainWindow.show()
sys.exit(app.exec_())
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
Your autogenerated ui file

#create a new object

I have a gui application
I put text into text box and then click on the pushButton,
The function callprinttext() in the moduel_b.py be called.
The function callprinttext() is calling method printtext() in the moduel_c.py
but I have an error:
AttributeError: 'class_c' object has no attribute 'lineEdit'
can anyone help me with class_c?
Here's the code for that:
module_c.py
class class_c (object):
def __init__(self, parent=None):
self.parent=parent
### I want a fix for error here
def printtext (self):
t=unicode(self.lineEdit.text())
print t

Well, one way to do it is using a call back method, this way:
In main.py
QtCore.QObject.connect(self.ui.pushButton, QtCore.SIGNAL("clicked()"), self.call_back)
def call_back(self):
txt = str(self.ui.lineEdit.text()) #lineEdit.text() returns QString Object so we need to convert it to String object
instance_b.callprinttext(txt)
Then in your calss_b method:
def callprinttext (self, txt):
from module_c import class_c
instance_c=class_c()
instance_c.printtext(txt)
And Finally in your class_c method:
def printtext (self, txt):
t=unicode(txt)
print t
EDIT :
If you don't want to add any call back method, then do it using lambda, this way:
QtCore.QObject.connect(self.ui.pushButton, QtCore.SIGNAL("clicked()"), \
lambda: instance_b.callprinttext(self.ui.lineEdit.text()))
And there is no need for call_back
For example, clicking button in main window calls test() function to add some text to textEdit box in main window

I know I shouldn't noodle with the generated file, just trying to figure out how to reference main window objects from a function outside that class.
I think the easiest way would be to make test an instance method of Ui_MainWindow, and save the MainWindow object as an instance variable of Ui_MainWindow, as well.
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName(_fromUtf8("MainWindow"))
MainWindow.resize(800, 600)
self.main_window = MainWindow
# blah blah
self.textEdit = QtGui.QTextEdit(self)
self.pushButton = QtGui.QPushButton(self)
self.pushButton.clicked.connect(self.test)
def test(self):
self.main_window.textEdit.append('button pushed')
If you really wanted test to be a top-level function, you could also use functools.partial to pass the MainWindow object along when the test callback is executed:
from functools import partial
def test(MainWindow):
MainWindow.textEdit.append('button pushed')
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName(_fromUtf8("MainWindow"))
MainWindow.resize(800, 600)
# blah blah
self.textEdit = QtGui.QTextEdit(self)
self.pushButton = QtGui.QPushButton(self)
test_func = partial(test, MainWindow) # Calling test_func(arg) actually calls test(MainWindow, arg)
self.pushButton.clicked.connect(test_func)
The possible is pass object QtGui.QMainWindow to method do your want, pass the MainWindow object to test() by using partial to pass parameter your want;
from PyQt4 import QtCore, QtGui
from functools import partial
.
.
.
def test(MainWindow):
MainWindow.textEdit.append('button pushed')
def setupUi(self, MainWindow):
.
.
.
MainWindow.textEdit = QtGui.QTextEdit(self.centralwidget) # Pass to QMainWindows not self
MainWindow.textEdit.setGeometry(QtCore.QRect(30, 80, 341, 441))
MainWindow.textEdit.setObjectName(_fromUtf8("textEdit"))
MainWindow.setCentralWidget(self.centralwidget)
.
.
.
self.retranslateUi(MainWindow)
QtCore.QObject.connect(MainWindow.pushButton, QtCore.SIGNAL(_fromUtf8("clicked()")), partial(test, MainWindow))
QtCore.QMetaObject.connectSlotsByName(MainWindow)
.
.
.
