PyQt4 sharing QLineEdit variable across .py files

PyQt4 sharing QLineEdit variable across .py files - python

I want to pass self.user = QtGui.QLineEdit(MainWindow) variable from Login.py to officer = str(self.tocomb.currentText()) in ingooi.py
My 3 GUI windows
My program consists of various files where I import the classes from other files as needed.
The 3 main files consists of :
Login.py ( My Login window where user logs in )
page22.py ( User selects to enter/view data )
ingooi.py ( User enters data then adds the data to access database via Submit
Button
Please see the code for these 3 main files below.
Login.py

The problem is in your design, you should not think that each file is a different program, it is really only one.
Another recommendation is that you do not modify the code generated by QtDesigner, this is not necessary also if you want to modify something in the GUI will erase all the above, for example if you have a design for example the Login.py:
class Ui_Logged(object):
def setupUi(self, MainWindow):
[...]
Then you must create another class that implements the logic
class Login(QtGui.QMainWindow, Login.Ui_Logged):
def __init__(self, *args, **kwargs):
QtGui.QMainWindow.__init__(self, *args, **kwargs)
self.setupUi(self)
[...]
then in your case you have to Page1() member of the class and show it when you call WW(), you should not create it just open it
class Login(QtGui.QMainWindow, Login.Ui_Logged):
def __init__(self, *args, **kwargs):
QtGui.QMainWindow.__init__(self, *args, **kwargs)
self.setupUi(self)
self.Login_button.clicked(self.slot1)
self.window = Page1()
def WW(self):
self.window.show()
self.hide()
The same thing you have to do in Page1() with each slot. NextPage() is the class that implements the logic of Ui_NextPage()
class Page1(QtGui.QMainWindow, Page22.Ui_Page1)
def __init__(self, *args, **kwargs):
QtGui.QMainWindow.__init__(self, *args, **kwargs)
self.setupUi(self)
self.pushButton.clicked.connect(self.dataenter)
self.pushButton_2.clicked.connect(self.dataview)
self.pushButton_3.clicked.connect(self.Taview)
self.pushButton_4.clicked.connect(self.exit)
self.nextPage = NextPage()
def dataenter(self):
self.nextPage.show()
[...]
So if we have that logic it's easy to call to access the QComboBox from slot():
def slot1(self):
uName = self.user.text()
uPass = self.password.text()
combo = self.window.nextPage.tocomb
items = [combo.itemText(i) for i in range(combo.count())]
if uName not in items:
combo.addItem(uName)
combo.setCurrentTex(uName)
I have tried to order your code, maybe have import problems but I think they should be minimal so you can fix them, run the file main.py. The complete code can be found at the following link.

I don't use pyqt4 so I have had to rely on the manual.
Using the QTextEdit widget, you access value using toPlainText().

location = self.plainTextEdit_location.toPlainText()
print "%s" % (location)
date = self.textEdit1_date.toPlainText()
print "%s" % (date)

dept1_rangefrom = self.plainTextEdit1_from1.toPlainText()

dept2_rangefrom = self.plainTextEdit2_from2.toPlainText()
print "%s" % (dept2_rangefrom)
dept1_rangeto = self.plainTextEdit4_to.toPlainText()

The line self.w.show, where you've declared w as a Ui_dialog object, will attempt to call the show instance variable inside Ui_dialog, which doesn't work because you've never defined any function called show.
It doesn't help that you've inherited object for class Ui_dialog. You should probably inherit QtGui.QDialog for that class, and rewrite your class accordingly.

When I run my code I have error
Traceback (most recent call last):
File "/home/develop/PycharmProjects/untitled/form_window.py", line 18, in <module>
class Ui_MainWindow(QtGui.QMainWindowWidget):
AttributeError: 'module' object has no attribute 'QMainWindowWidget'
I have no idea what I'm doing wrong

I don't see a class QMainWindowWidget in the api: http://pyqt.sourceforge.net/Docs/PyQt4/qtgui.html
Are you sure you don't mean to inherit from QMainWindow instead?
