pyqt and table widget clear contents - python

I am new to PYQT and I am trying to get a feel for it. I am trying to populate a table widget with 5 different push buttons. I need to clear out the table between each button push, but would like to leave the headers I have. I have tried a tablewidget clearcontents. but that clears everything and I am unsure of where to place it properly so it will clear the contents before each button push, that brings in the new info.

You can use the clearContents() method when you set the table headers in an appropriate way.
change:
self.tableWidget.setItem(0,0,QtGui.QTableWidgetItem("name"))
self.tableWidget.setItem(0,1,QtGui.QTableWidgetItem("column_1"))
self.tableWidget.setItem(0,2,QtGui.QTableWidgetItem("column_2"))
self.tableWidget.setItem(0,3,QtGui.QTableWidgetItem("column_3"))
self.tableWidget.setItem(0,4,QtGui.QTableWidgetItem("column_4"))
to:
self.tableWidget.setHorizontalHeaderItem(0, QtGui.QTableWidgetItem("name"))
self.tableWidget.setHorizontalHeaderItem(1, QtGui.QTableWidgetItem("column_1"))
self.tableWidget.setHorizontalHeaderItem(2, QtGui.QTableWidgetItem("column_2"))
self.tableWidget.setHorizontalHeaderItem(3, QtGui.QTableWidgetItem("column_3"))
self.tableWidget.setHorizontalHeaderItem(4, QtGui.QTableWidgetItem("column_4"))

Maybe this helps you? I tried keeping as much of your code.

Generally when I have windows working together I will set one as the others parent or have methods for one that receives data from the other. For example:
class MainWindow(QtWidgets.QMainWindow, Ui_MainWindow):
def __init__(self):
QtWidgets.QMainWindow.__init__(self)
self.setupUi(self)
self.run_btn.clicked.connect(self.setup_project)
def setup_project(self):
self.project = ProjectParams(parent=self)
self.project.show()
if self.project.exec_() == QtWidgets.QDialog.Accepted:
self.params = self.project.params
self.loops = self.project.loops
class ProjectParams(QtWidgets.QDialog, Ui_ProjectParams):
def __init__(self, parent=None):
QtWidgets.QDialog.__init__(self, parent=parent)
self.setupUi(self)
self.buttonBox.button(QtWidgets.QDialogButtonBox.Ok).setEnabled(False)
self.params = {}
From your error I would think you need to change:
self.connect(self.pushButton, QtCore.SIGNAL('clicked()'), self.open)
to:
self.pushButton.clicked.connect(self.open)

sorry if the alignment is off i am not used to having to use stack overflow but the code results in the following output:

File "C:\Users\todd7\Desktop\PY_auth\design.py", line 28, in main
w = Ui_Dialog(__init__)
NameError: name '__init__' is not defined
and i am not sure how to fix the issue.
Try making your __init__ function in your Ui_Dialog class this:
def __init__(self, window, parent=None):
self.addWidgets()
self.setupUi(self)
window.show()
Then, in your main() function,
def main():
app = QtGui.QApplication(sys.argv)
w = Ui_Dialog(QtGui.QMainWindow())
sys.exit(app.exec_())

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.

ex.show()
sys.exit(app.exec_())
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?
