On to my Swift #learning updates.
I'm currently working on the second app that passes mock data into a Sheet Detail View. Nothing too challenging but I'm really enjoy learning #Swift.
It uses a #ModelView to #StateManagement its data. This was a new concept to me coming from JS.

Introduction to Qt Widgets (Part 54) - Model/View Concepts After two episodes talking about the item versions of lists, tables, and trees, we now turn our attention to the model/view version of that story. Using model/view offers a great opportunity to do a separation between business logic and presentation. In this episode we will start the journey from 10.000 feet, learning how each of the parts fits together. Chapters: 00:00 Welcome 00:42 So what is model/view? - One definition I didn't understand 02:35 Model/view for lists, tables and trees 03:55 Advertise: profiling training 04:10 Model/View isn't the right name 05:26 Some examples of models 08:47 QAbstractItemModel 11:20 The key problem in Qt's Model/view framework 14:20 The views 16:26 The example 18:12 The relationship model, view, and delegate Links: * KDAB Profiling Training Portfolio: https://training.kdab.com/portfolio/debugging-and-profiling/ * KPhotoAlbum: https://www.kphotoalbum.org/ The example code showcased in this video is available here: https://github.com/KDABLabs/kdabtv/tree/master/Programming-With-Qt-Widgets/modelview All 'Introduction to Qt Widgets - Module 1' videos: https://www.youtube.com/playlist?list=PL6CJYn40gN6hgf7zCKF2Rv9Y0WoN8RVGf All...

After exploring item-based lists, tables & trees, we're now diving into the model/view approach. A great step toward clean separation of logic & presentation. In this episode, we zoom out to see how it all fits together: www.youtube.com/watch?v=jQLN... #QtDev #QtWidgets #ModelView

Introduction to Qt Widgets (Part 52) - Item Views Qt has two kinds of lists, tables, and trees. One kind uses a model/view setup which gives a great separation between data and presentation. The other one is item based, meaning your data is stored in the items, just like the checked value is stored inside the checkbox. The disadvantage with the model/view framework is that it is more work to set up, which is why we will start this module with the much simpler item based version. Chapters: 00:00 Introduction 00:45 The Widget versus the View classes 03:55 QListWidget 08:40 QTableWidget 10:16 The table widget example 15:47 Advertise - can you help us with a USB driver? 16:11 QTableWidget::addItem - of course doesn't exist 16:55 QTreeWidget 20:35 The tree widget example 24:00 Compare the API of list, table, and tree 24:35 Configuring items 27:00 Headers 29:06 Whats up in the next episode Links: * Table View Galore : https://youtu.be/F8min4ZZJaI?list=PL6CJYn40gN6gf-G-o6syFwGrtq3kItEqI...

Episode 52 of "Introduction to Qt Widgets" is out now. This is the first episode of Module 8, where we look at item-based lists before getting into Qt's model/view framework. Watch it here: www.youtube.com/watch?v=pU66... #QtDev #QtWidgets #ModelView #CPlusPlus #Cpp

Model/View Drag and Drop in Qt - Part 3: Moving/copying items onto existing items | KDAB Implementing item drops in the model/view qt involves dropping onto items. Emails moved between folders are a common example of applying this approach.

In the final part of this blog series, David Faure (KDAB) explores implementing drag-and-drop onto existing Qt items, like moving emails between folders. It covers #ModelView and Item Widget approaches, key setup steps, and Qt improvements: www.kdab.com/modelview-dr... #QtDev #Cpp
