Qt comes with a number of dialogs for the most common use cases:
- Asking for a file name, a color, or a font, or a simple string (Hey what is your name?
- Displaying a simple text message.
- Showing the progress of your current task

In addition, it has a framework for implementing a wizard.
You will learn about all of the above in this episode.

Introduction to Qt Widgets (Part 29) - Dialogs

In Qt, you can create a top level window, simply by providing nullptr as the parent. However, we still have a class called QDialog specifically for creating dialogs. Among other things it offers to wait for the dialog to be completed before your code continues execution.

In this episode, we will also discuss the difference between a model and non modal dialog, and how you create your own.

What is the difference between update and repaint?

Have you ever wondered what the difference is between QWidget::repaint() and QWidget::update()?
You may even have heard that update events collapsed into just one event in the event loop, which might make you ask the question on whether there are other events merged together.

Let's debug into the Qt source code to get an answer.

0:00 Intro 
0:27 Repaint and update and tearing
3:47 Seeing the call stack for repaint in the debugger
6:25 Now see the call stack for update

Adding Double Click to a QPushButton

The task was simple: Add double click to a push button - with the added bonus of it not emitting the normal clicked if there is a double click.

OK, this sounds trivial, right? Well no, it wasn't entirely. To get it right you have to understand quite a bit of both signals/slots and the event system.

0:00 Introduction
0:22 A push button emitting double click - without emitting single click
1:44 Part 1 - Override mouseDoubleClickEvent
2:41 Part 2 - Introducing the crystal ball (a QTimer to postpone the single click signal)
4:58 Part 3 - Ensure up state is painted, but that the super class doesn't emit the signal - using QSignalBlocker
6:05 Part 4 - Understanding why we get the late "Thanks"
10:23 Part 5 - Simply use a flag to block the false event
11:56 Wouldn't it have been easier to implement a new button from scratch?

Show Me Your IDE: VSCode

In this last episode on "Show me your IDE", we now look at visual studio code.

0:00 Intro
0:47 Debugging on windows is faster than in Qt Creator
2:37 It is very nice and clean
3:00 Git management
5:02 The IDE overall is fast - esp wrt peek
7:03 Getting started you need plugins
8:56 Qt Creator is better than VSCode when it comes to Qt refactorings
10:47 Qt Designer
12:23 Why are refactorings missing?
14:42 VSCode on Linux and Mac?
15:31 Search and replace across lost of files - preserve case
18:02 So, you are switching to Visual Studio?
