Source Codes: https://codeloop.org/category/pyqt5/ PyQt5 Signal And Slots Basics Pyhton GUI Programming Graphical applications (GUI) are event-driven, unlike console or terminal applications. A users action like clicks a button or selecting an item in a list is called an event. If an event takes place, each PyQt5 widget can emit a signal. A signal does not execute any action, that is done by a slot.

Ch 1 - Introduction 0:38 Ch 2 - Getting Started 9:48 Ch 3 - Fundamentals 18:02 Ch 4 - General Examples 57:31 Ch 5 - PyQt4 Maya Intro 1:46:19 Ch 6 - Replicating Maya’s UI Components 1:58:03 Ch 7 - Styling Style Sheets 3:46:49 Ch 8 - Outro 4:41:20 Project materials available here: https://github.com/justinfx/tutorials/tree/master/PyQt4_UI_Development_for_Maya Introduction - 0:38 This tutorial is about learning PyQt4 python bindings for the Qt Framework, and how to introduce new UI elements to Maya as a platform. We discuss what comprises a “Framework” and a “GUI Framework”, and how Qt and PyQt4 work together. Getting Started With PyQt4 - 9:48 There are multiple ways of getting a working installation of PyQt4, both for the general system and for Maya. We look into these approaches to get your system up and running to begin working with PyQt4! We also talk about what is included, such as command line tools and applications, tips on how to test and learn the code, and how to structure a project. PyQt4 Fundamentals - 18:02 Lets get crackin’ and learn the basics! • What is a QObject? What is a QWidget? Common PyQt4 classes are explained in detail • Working with the Qt Designer application, to build a UI visually • Layouts: Making widgets resize elegantly and stay organized in your design • Coordinate space: How do widgets transform in your 2D screen space? • QApplication and the Qt Event Loop: The engine that runs your UI • Events, Signals, and Slots: How components communicate changes and how the application can respond to changes to make it dynamic General Examples - 57:31 With an understanding of the framework components, we can begin working with fully functional stand-alone examples. • Common PyQt4 app template • Subclassing Widgets: Creating custom functionality to the existing classes provided by PyQt4 • Dialogs: Raising dialog windows above existing windows, Modal vs Non-modal, and creating forms. We look at different ways to validate the data provided by the user, to these dialog forms. PyQt4 And Maya Introduction - 1:46:19 Finally, some Maya action! Maya has a slightly different approach to using PyQt4… • How does the QApplication and event loop work? • Common Maya PyQt4 app template • Looking at the Maya API’s MQtUtil class • The sip module: Helping us translate between Maya’s Qt and our own PyQt4 code Replicating Maya’s UI Components - 1:58:03 What better way to see examples of creating UI for Maya than to replicate some existing functionality? This gives us the opportunity expand with custom functionality In this chapter we will take two different UI components in Maya, and do a basic custom version of our own, and show to how link them up to Maya’s own callbacks. Some Features Of This Chapter Include • The QTableWidget • Model / View separation with QTreeView • Docking windows into the Maya interface • Mixing together PyQt4, the Maya API, Maya commands, and callbacks • Sorting model data Customizations - 3:46:49 A button can be a button, and a slider might look alright in its stock form, but sometimes we want to customize the look of our widgets. This chapter introduces multiple ways of achieving custom looks to our components • Stylin’ Stylesheets: Use CSS-like syntax for applying style sheets to widgets • Painting By … Paint events: For even more control, we can tell a widget exactly how to draw itself on the screen. We will look at two different examples of how to use custom painting.

PyQt5 Creating QCheckBox With Signals (Python GUI Development)  #10
 
17:34
Check our blog for source code https://codeloop.org/category/pyqt5/ This is our tenth video in Python GUI Development with PyQt5, in this video i want to show you how to Create QCheckBox With Toggled Signal In PyQt5 What Is QCheckBox ? The QCheckBox widget provides a checkbox with a text label. A QCheckBox is an option button that can be switched on (checked) or off (unchecked). Checkboxes are typically used to represent features in an application that can be enabled or disabled without affecting others, but different types of behavior can be implemented. For example, a QButtonGroup can be used to group check buttons logically, allowing exclusive checkboxes. However, QButtonGroup does not provide any visual representation. Whenever a checkbox is checked or cleared it emits the signal stateChanged(). Connect to this signal if you want to trigger an action each time the checkbox changes state. You can use isChecked() to query whether or not a checkbox is checked. In addition to the usual checked and unchecked states, QCheckBox optionally provides a third state to indicate "no change". This is useful whenever you need to give the user the option of neither checking nor unchecking a checkbox. If you need this third state, enable it with setTristate(), and use checkState() to query the current toggle state. Just like QPushButton, a checkbox displays text, and optionally a small icon. The icon is set with setIcon(). The text can be set in the constructor or with setText(). A shortcut key can be specified by preceding the preferred character with an ampersand Qt Documentation For QCheckBox http://doc.qt.io/archives/qt-4.8/qcheckbox.html Complete Playlist For Python GUI Development With PyQt5 https://www.youtube.com/watch?v=yD0iu3n-e_s&list=PL1FgJUcJJ03uO70zDLDF3oaTu6s2QLOPa

PyQt5 Creating QLineEdit With returnPressed Signal  (Python GUI Development)  #12
 
09:21
Check our blog for source code https://codeloop.org/category/pyqt5/ This is our twelfth video in Python GUI Development with PyQt5, in this video i want to show you how to Create QLineEdit With returnPressed Signal In PyQt5 What Is QLineEdit Class ? A line edit allows the user to enter and edit a single line of plain text with a useful collection of editing functions, including undo and redo, cut and paste, and drag and drop (see setDragEnabled()). By changing the echoMode() of a line edit, it can also be used as a "write-only" field, for inputs such as passwords. The length of the text can be constrained to maxLength(). The text can be arbitrarily constrained using a validator() or an inputMask(), or both. When switching between a validator and an input mask on the same line edit, it is best to clear the validator or input mask to prevent undefined behavior. A related class is QTextEdit which allows multi-line, rich text editing. You can change the text with setText() or insert(). The text is retrieved with text(); the displayed text (which may be different, see EchoMode) is retrieved with displayText(). Text can be selected with setSelection() or selectAll(), and the selection can be cut(), copy()ied and paste()d. The text can be aligned with setAlignment(). When the text changes the textChanged() signal is emitted; when the text changes other than by calling setText() the textEdited() signal is emitted; when the cursor is moved the cursorPositionChanged() signal is emitted; and when the Return or Enter key is pressed the returnPressed() signal is emitted. When editing is finished, either because the line edit lost focus or Return/Enter is pressed the editingFinished() signal is emitted. Note that if there is a validator set on the line edit, the returnPressed()/editingFinished() signals will only be emitted if the validator returns QValidator::Acceptable. By default, QLineEdits have a frame as specified by platform style guides; you can turn it off by calling setFrame(false). The default key bindings are described below. The line edit also provides a context menu (usually invoked by a right mouse click) that presents some of these editing options.

Десктоп приложения на PyQT
 
01:01:59
В современном мире очень много языков программирования для решения множества задач. Для создания десктопных приложений изначально были популярны языки, такие как C, а затем и C++, но процесс написания был очень долгим и сложным. С появлением высокоуровневых языков задача упростилась и сейчас можно довольно быстро писать приложения на C#, Java, Ruby on Rails и Python. В арсенале Python есть мощнейшая библиотека PyQt для создания десктопных приложений, это привязка графического фреймворка Qt языка C++. На вебинаре мы напишем программу для создания скриншота экрана и скачивания файлов из интернета. А также посмотрим, как их запаковать в exe файл и сделать инсталятор.

Это видео продолжает серию видео-записок по Python с обзорами практических приёмов программирования. В этой видео-заметке продолжаю обзор возможностей PyQt5, а именно разбираю приемы программирования с использованием нескольких потоков посредством класса QThread. При этом QThread - это не поток, а Qt обертка для потока конкретной ОС, которая позволяет взаимодействовать с потоком из Qt проекта, в первую очередь через Qt signals/slots.
