Qt Designer's Signals and Slots Editing Mode | Qt 4.8 In Qt Designer's signals and slots editing mode, you can connect objects in a form together using Qt's signals and slots mechanism.Both widgets and layouts can be connected via an intuitive connection interface, using the menu of compatible signals and slots provided by Qt Designer.When a form is saved, all connections are preserved so that they will be ready for use when your project is built. Using Qt Designer — FATSLiM 0.1.3.dev0 documentation Writing Qt Designer Plugins¶ Qt Designer can be extended by writing plugins. Normally this is done using C++ but PyQt5 also allows you to write plugins in Python. Most of the time a plugin is used to expose a custom widget to Designer so that it appears in Designer's widget box just like any other widget. Designing Custom Controls with PyQt - Qt Documentation The declaration immediately before the setter is a special Python decorator that tells Qt that setLatitude() is a slot and that it accepts double precision floating point values. Typically, this kind of declaration is not required with PyQt—any function or method can be used as a slot—but this makes interacting with Qt Designer easier later on.
@lunaryorn thanks. Sorry but how do you create the slot "my_custom_function" in order to bind it to the clicked() signal of the pushButton on the Signal/Slot editor. Maybe I miss something but I can not find the way in designer documentation, where I just found how to bind sender and receiver predefined signals and slots .
I'm using Qt Creator 2.0.1 and I have a custom slot my QMainWindow ... now I have a pushbutton, which on clicked should call the custom slot on the main window. Can do in code yes, but can't do this with the signal-slot editor. When I open the signal-slot editor, I see the custom slot on the right but the entire set of slots are disabled. Signals and Slots in PySide/ko - Qt Wiki #!/usr/bin/env python import sys from PySide import QtCore # define a new slot that receives a string and has # 'saySomeWords' as its name @ QtCore.

Hello Qt for Python - Qt Blog Are their currently efforts being made making Qt for Python more native feeling – if not – is this in long-term view? E.g. context managers for Layouts, decorators for slots, iterators for children etc? (or at the other hand, Qt Creator?)

I was going through the "Getting started" section for Qt using VS2012 as my IDE, and I got stuck when I had to add a slot to a button. Apparently there is a bug when using the Visual Studio add-in, that the submenu Go to slot doesn't show up in a context menu in Qt Designer (see bug).

PyQt4 does not allow Python classes to be sub-classed from more than one Qt class. Designer can only connect Qt signals and slots. It has no understanding of Python signals or callables. Designer can only edit Qt properties that represent C++ types. It has no understanding of Python attributes or Python types.
Creating Custom Widgets for Qt Designer Qt Designer 's plugin-based architecture allows user-defined and third party custom widgets to be edited just like you do with standard Qt widgets.
