Things have been hectic since the XE4 launch. We’ve had in-person events in lots of countries around Asia. I’ve done Japan, South Korea and Taiwan, but they’ve also been happening in Australia (with ADUG) and China, and we’ve had lots of webinars as well.
What has been really encouraging is the number of new people at the events. I’ve spoken to Xcode developers, Visual Studio developers and Java developers across multiple countries who are all trying out Delphi for the first time. Read On…
I’ve been working on a ShowCase App for the Delphi XE4 release, and as part of it I wanted to have a “drawer” layout. I first saw this in the iOS and Android Facebook app, but it has shown up in other apps since.
If you’re not familiar with this, it is where your main content takes up the bulk of the screen, except for a toolbar at the top. The toolbar has a “hamburger” button that slides the main content area over to the right to expose a second content area (often a menu) underneath. Read On…
Here are the resources I mentioned in my Introduction to MVVM in Delphi session at CodeRage 7. There are many more MVVM resources out there, but I’ve tried to keep this as the short-list of those I’ve found truly useful. I’ll update as I encounter more. Read On…
CodeRage 7 is on next week and I’ll be doing a session introducing MVVM and how to implement it in Delphi. If you’re not aware of MVVM, it’s a Presentation Pattern, a way to structure your applications so that you maximize the amount of code in your app that can be unit tested (including your form logic) while at the same time, simplifying the task of swapping out different UI’s in front of your app (eg. to have different forms for different platforms or devices). It leverages Data Binding, in my case, LiveBindings in XE3.
I have a series of deeper dive articles planned on different areas of MVVM in Delphi, and this session will serve as the starting point.
Session details are here.
In the last post I looked at formatting the data we’re binding to our UI. This post is related, but it might take a little while to see how.
Back when I wrote about TAdapterBindSource, one of the adapters I used was a TDataGeneratorAdapter. This combination was useful to give me both a) design-time fields from which to visually bind in the LiveBindings Designer and b) design-time data in those fields to help layout my UI more easily.
