Python generated file changes not detected byQFileSystemModel

Mads Ipsen — 2012-05-22T09:51:38

Hi,

Here's the problem:

 1. Set up a QFileSystemModel, call setRootPath() and hook up to the
    dataChanged signal.
 2. Open a new file from Python and write some text into it. Then close it.
 3. Reopen the file in append mode and write some more text into it.
    Then close it.
 4. Open a file in an external editor. Write some stuff. Save. Write
    more stuff. Save.

If you do (3), the dataChanged signal is NOT emitted. However, if you do 
(4), the dataChanged signal IS emitted.

Any clues? An attached file that reproduces the issue is attached.

Best regards,

Mads

Re: How do you compile 64bit PyQt on Windows w/o VisualStudio.

Roger Oberholtzer — 2012-05-21T20:19:49

There is tons of compiled Windows software on the openSUSE Build 
Service. Granted, they are packaged in RPMs. But they really are the 
compiled things just needing to be unpacked somewhere. You will find QT 
and more.

http://download.opensuse.org/repositories/windows:/mingw:/win64/openSUSE_12.1/noarch/

There are 32-bit versions in a parallel directory. Don't be put off by 
the RPM format. The files can easily be unpacked. I see that 7-zip 
(http://www.7-zip.org/) claims to support RPM files. I actually install 
them in Linux via my Linux package manager, and then can easily 
repackage the tree for various uses. Doing this keeps the Windows and 
Linux version in sync, making cross platform support so very much easier.

Re: From/Import, proper namespace,etc

JPolk — 2012-05-21T17:20:23

Thanks Phil,
...(yes, I see the design flaw you speak of...was doing a bit of testing)

Just to add for prosterity,...your answer had a small typo...just needs a
".connect"
statement in there....so for others who may find this later,..the statement
is:

      self.button.clicked.connect(lambda checked: DoTest2(self))  

I did find another method (better design? dunno ;-) and that is to have the
button connect
statement call a local (in file A) function which in turn calls B.function()

Using,
     from B import *
     .....
     self.Button_02.clicked.connect(self.DoTest1)
     ....

            def DoTest1(self):
                print("DoTest1")
                status = DoTest2(self)
                print status


Thanks again,

Loading a QMainWindow with uiloader

Angelo Compagnucci — 2012-05-21T09:43:14

Hi guys,

I have done this:

def setupUi(self, MainWindow):
        loader = QUiLoader()
        file = QFile("...")
        file.open(QFile.ReadOnly)
        centralwidget = loader.load(file, self)
        centralwidget.setWindowFlags(Qt.Widget)
        self.setCentralWidget(centralwidget)

It works, but the real centralWidget is nested into the main QMainWindow
centralWidget, so to set my own centralWidget, I have to do:

self.centralWidget().setCentralWidget(...)

There is a better way to load a QMainWindow from a ui file via QUiLoader?

Thank you!

PyQtProxy and QNetworkAccessManager segfault

GeoTux Tuxman — 2012-05-21T09:16:06

Hi all, 

just to let you know I had the same trouble mentioned in this thread [1] regarding PyQtProxy when disconnecting the QNetworkAccessManager.finished() signal. I was using PyQt4 4.8.5, Qt4 4.7.1, SIP 4.12.4 and Python 2.7 on Linux Mint v.12 (Ubuntu Oneiric). 

As it is mentioned in the thread, the bug disappears if one passes the slot as an argument of disconnect, e.g. self.myQNAM.finished.disconnect(self.mySlot)

Regards,  

Germán

If you're running this locally, fedora pretty generally (and implicitly)

yum groupinstall base-x fonts

If you experience badness after doing so (or can further isolation what 
pieces were missing), please do file a bug < at > bugzilla.redhat.com

Hello. I'm learning PyQt for use with Designer for database applications.  
I've been reading all the resources and tutorials, and I have a good amount  
of 
experience with GUI and Database programming in MS ACCESS. I have finally 
decided to put in the effort to lear python and QT but i'm stuck and 
need help seeing what I'm doing wrong. 

I have Ui_Clients.py generated by Eric from "clients.ui" created by  
Designer.

class Ui_MainWindowClients(object):
    def setupUi(self, MainWindowClients):
        MainWindowClients.setObjectName(_fromUtf8("MainWindowClients"))
        MainWindowClients.resize(640, 480)

... etc
Among the widgets is QtGui.QTreeView "ClientTreeView" as follows:

        self.ClientTreeView = QtGui.QTreeView(self.centralwidget)
        self.ClientTreeView.setGeometry(QtCore.QRect(30, 290, 401, 111))

... etc ending with

        self.ClientTreeView.setObjectName(_fromUtf8("ClientTreeView"))

I also have Clients.py as generated by Eric from "clients.ui"

class MainWindowClients(QMainWind

I think I figured this out once, lol...but can't seem to recall...
Consider you have two python files,..."a" and "b"...where you "launch a" and
"import b".
But inside "b" is a PyQt call back to a control defined in "a".  I keep
getting a "not defined" error...
So,...

=======================================
File "A"
=======================================
#!/usr/bin/env python

import os
import sys
from PyQt4 import QtCore, QtGui, uic

*from b import **

class MainWindow(QtGui.QMainWindow):
        def __init__(self, parent=None):
                super(MainWindow, self).__init__(parent)

                self.setGeometry(520, 285, 640, 480)
                self.Button = QtGui.QPushButton(self)
                self.Button.setGeometry(QtCore.QRect(105, 140, 151, 66))
                self.Button.setObjectName("Button")
                self.Label = QtGui.QLabel(self)
                self.Label.setGeometry(QtCore.QRect(350, 250, 101, 21))

Good point.  The only binary release of the Qt libs for MinGW appear to be for the 32 bit version.  I see references on the web that there once were Qt libs for MinGW64, but they don't appear to be around any more.  I tried compiling QT from source using mingw-w64, but configure doesn't seem to like 'win32-g++' as an argument to platform & I don't see a way to list available platforms. Looking through the configure shell script shows 'win32-g++' should be a valid option.  I think I'm giving up on this option.


In the interest in putting out what I hope to be accurate information,  I downloaded mingw just a few days ago.  It (compiling sip) does not work unless libpython26.a is in c:\python26\libs.  I just tested this again...

with libpython26.a:

configure --platform=win32-g++

Wrap C++ classes using SIP

Jayesh Chaudhary — 2012-05-18T22:13:37

Folks,

I am a newbie to SIP. I am trying to wrap couple of classes and it was
going good till I hit this problem.

So here is my use case:

Lets say I have two classes Foo and Bar. I already have Bar wrapped (not
via SIP though) and now I am trying to wrap Foo using SIP.

My Foo looks like this:

Class Foo: public Bar
{
};


I don't want to wrap Bar again with SIP since this will trigger a chain
reaction. In my SIP I have done something like this:

%Module FooMod

class Foo: Bar
{
%TypeHeaderCode
#include<Foo.h>
%End
...
...
};

But then if I don't wrap Bar, I get Bar undefined. Is there a way around
it?

Many thanks for your help.

Best,

Re: Time auto update to my widget

Take a look at the widgets/analogclock example in the PyQt archive.
This uses a timer to update the widget once every second.

Vim PyQt code completion

Cihangir Aktürk — 2012-05-18T20:46:12

Hi,

I am using Vim's internal pythoncomplete. It works pretty good most
of the time. But I am having problems with PyQt code completion.
First of all, let me give you some more details.

When I do;

from PyQt4 import QtGui
w = QtGui.QWid  # c - x c - o works here as expected,
w.              # c - x c - o also does the right thing here

but when i write code like this

class Foo():
    def bar(self):
        self.w = QtGui.QWidget()
        self. # c - x c - o omnicompletion doesn't work for this kind
of expressions.

As seen from above, on class members I did not manage to work
completion. This problem _only_ applies to PyQt4 module, other
than PyQt I get a proper completion, even for class members.

What can I do to get a proper code completion for PyQt module?

Best regards.
