Empathy is the official instant messaging application of the GNOME desktop environment. Empathy can connect to AIM, MSN, Jabber (including Facebook and Google Talk), IRC, and many other messaging networks. You can chat with text, make audio and video calls, or even transfer files, depending on what your contact’s chat application allows.

Thanks for your answer, I wrote the same question to the PyQt mail list and they answered me that my approach was wrong. I should rewrite the code and implement an event handling system. The solution they suggested me is to forget about signal&slot and write the following function outside the .__init__ function. "PyQt is a set of Python v2 and v3 bindings for The Qt Company's Qt application framework and runs on all platforms supported by Qt including Windows, MacOS/X and Linux. PyQt5 supports Qt v5. PyQt4 supports Qt v4 and will build against Qt v5. The bindings are implemented as a set of Python modules and contain over 1,000 classes." Automatically Connecting Slots by Name. The code in attachment to replace connectSlotsByName() has been working great for me. I'm replacing more and more QObject.connect() -like code with it (I could not use the connectSlotsByName() from Qt because it binds callbacks twice (and yes, even if I did decorate my callbacks) and most importantly because my callbacks are not on the same object. I am trying to learn PyQt from rapid gui programming with python and qt and currently learning Signals and Slots.. Below is a short snippet of my code: self.connect(self.dial, SIGNAL("valueChanged(int)"),self.spinbox.setValue) #1 self.connect(self.dial, SIGNAL("valueChanged(int)"),self.getValue_dial) #2 self.connect(self.spinbox, SIGNAL("valueChanged(int)"),self.dial.setValue) self.connect Sending Python values with signals and slots. On the #pyqt channel on Freenode, Khertan asked about sending Python values via Qt's signals and slots mechanism.. The following example uses the PyQt_PyObject value declaration with an old-style signal-slot connection, and again when the signal is emitted, to communicate a Python dictionary.

In PyQt, connection between a signal and a slot can be achieved in different ways. Following are most commonly used techniques − QtCore.QObject.connect(widget, QtCore.SIGNAL(‘signalname’), slot_function) A more convenient way to call a slot_function, when a signal is emitted by a widget is as follows − widget.signal.connect(slot_function)

Jun 12, 2015 · PyQt4 is a comprehensive set of Python bindings for Digia’s Qt cross platform GUI toolkit. PyQt4 supports Python v2 and v3. PyQT is a Python wrapper around the QT framework for creating graphical user interfaces, or GUIs. This tutorial is written in PyQt4, but there is a newer version, PyQt5, that you can use. There are some differences, and kenwaldek has ported this series code, by individual tutorial code, to PyQt5 here. First, we need to go ahead and get PyQT4. PyQt can show a directory structure using a QTreeView. For the treeview to show as a directory tree, we need to set its model to a QFileSystemModel instance. That is achieved by calling the setModel method for the tree instance. We can set additional options on the tree object: sorting enabled (setSortingEnabled), animation and indention. Dear community, Currently I am working on a tutorial series on Cross Platfom Application Development using Qt, PyQt and PySide. I plan it to span into 7 articles, which will cover starting from the very basic aspect of Qt application development (installation, compiling, project management, unit testing, etc).

Then you don't need to connect the signals of the object, it will be automatically linked if a method with on_OBJECTNAME_SIGNALNAME exists in the self (e.g. QMainWindow) object: def on_controllerCombo_currentIndexChanged ( self , devModel ): self . info ( "In on_controllerCombo_currentIndexChanged) \t devModel: %s " % devModel )

Bibilioteke PyQt dopiero poznaję, ale zastosuję się do twoich rad odnośnie sygnałów i slotów. A co do wersji Pythona - używam 2.7. Zapewne masz rację powinienem zacząć używać wersji rozwojowej, choć jednak nie wiem jakie byłyby jeszcze zalety przejścia na Pythona 3

Install pyqt. PyQt is often not installed by default. The PyQt module can be used to create desktop applications with Python. In this article you’ll learn how to install the PyQt module. Desktop applications made with PyQt are cross platform, they will work on Microsoft Windows, Apple Mac OS X and Linux computers (including Raspberry Pi). 안녕하세요. 말씀하신대로 예제만으로는 이해하기 부족한 감이 있습니다. 제가 설명을 다 붙이면서 적기에는 시간이 부족하여 일단 코드만이라도 정리해서 올리고 있습니다. Apr 25, 2011 · A frequent question coming up when programming with PyQt is how to pass extra arguments to slots. After all, the signal-slot connection mechanism only specifies how to connect a signal to a slot - the signal's arguments are passed to the slot, but no additional (user-defined) arguments may be directly passed. c++,qt,connect,signals-slots. You need to create new slot for that purpose. But in C++ 11 and Qt 5 style you can use labmdas! It is very comfortable for such short functions. In your case: connect(ui->horizontalSlider, &QSlider::sliderMoved, this, [this](int x) { this->ui->progressBar->setValue(x / 2); }); Python PyQt Applications. Here’s a list of applications that make use of PyQt-Dropbox-File-hosting service. Spyder-Python IDE. Calibre-e-book management application. Leo-Outliner and literate programming editor. OpenShot-Video-editing program. Veusz-Scientific plotting application. Orange-Data-mining and visualization framework. What is PyQt Signals & Slots? Unlike a console mode application, which is completed in a sequential way, a GUI based application is event driven. functions or techniques are completed in reaction to user’s actions like clicking on a button, choosing an item from a set or a mouse click etc., known as events.
