[Solved] PyQt Dialog Window Not Popping up in Function

needhelp_gh

Hi,

I've spent many days trying to figure this out...

My dialog window is not popping up when being called from inside a function.

I've done this before & have been successful, but this particular one is not working.

Could there be a setting I messed up or missed?

This is my code:

@from PyQt4 import QtGui, uic, QtCore, Qt

def MAIN():
widget = uic.loadUi("/PATH/TO/file.ui")
widget.show()

MAIN()@

(I tried to simplify it as much as possible, but nothing works...)

But it works if I do this:

@from PyQt4 import QtGui, uic, QtCore, Qt

widget = uic.loadUi("/PATH/TO/file.ui")
widget.show()
@

Any ideas? Thanks!!

If the ui code would be useful, please let me know.

I've also replaced the dialog ui file for a window ui file & same thing...This is quite puzzling.

Any help would be appreciated!!

Try the following with your .ui file:

@
from PyQt4.QtGui import *
from PyQt4 import uic

class MainWindow(QMainWindow):
def init(self, parent=None):
QMainWindow.init(self, parent)

    self.ui.uic.loadUi("./example.ui")
    self.ui.show()

if name=="main":
from sys import argv, exit
a=QApplication(argv)
m=MainWindow()
exit(a.exec_())
@

It tends to be better to have an enclosing widget (QWidget, QMainWindow etc.). I don't use UI files very often but this is what I always do.

Hope it helps.

Hi,

Thanks for your reply, but is there any way to do it w/o classes/OOP?

Try this:

@
from PyQt4.QtGui import *
from PyQt4 import uic
from sys import argv, exit

def Main():
a=QApplication(argv)
ui=uic.loadUi("./example.ui")
ui.show()
return a.exec_()

Main()

Thanks again. I'm doing this inside another program, called Autodesk Maya 2012/2013, so that just crashes it with this error message:

QCoreApplication::exec: The event loop is already running
QClipboard: Unable to receive an event from the clipboard manager in a reasonable time
Segmentation fault (core dumped)

why would you call Main() twice?
