The first step in creating desktop applications with PyQt is getting a window to show up on your desktop. Thankfully, with PyQt that is pretty simple.
My book Create Simple GUI Applications with Python & Qt5 has been updated! New chapters on multithreading and packaging your apps.
With the release of Qt 5.5 the Qt WebKit API was deprecated and replaced with the new
QtWebEngine API, based on Chromium.
The WebKit API was subsequently removed from Qt entirely with the release of Qt 5.6 in mid-2016.
System tray applications (or menu bar applications) can be useful for making common functions or information available in a small number of clicks. For full desktop applications they're a useful shortcut to control apps without opening up the whole window.
A common problem when building GUI applications is "locking up" of the interface when attempting to perform long-running background tasks. In this tutorial I'll cover one of the simplest ways to achieve concurrent execution in PyQt.
PyQtConfig: a simple API for handling, persisting and synchronising configuration within PyQt applications. This module was built initially as part of the Pathomx data analysis platform but spun out into a standalone module when it became clear it was quite useful.
Below is a short snippet to implement a color-picker attached to a button in Qt. Clicking on the button pops up a dialog (native) to select a color. The color is shown by the color of the button face. A right-click option is included to allow clearing of the color setting (returning the value to None).
Signals are a neat feature of Qt that allow message-passing between different areas of your program.
