Using Dash with Qt Creator

If you are developing on a Mac, then you may have heard of a great documentation tool called Dash. It's particularly helpful if you are developing with multiple languages at the same time and don't want to go a search engine for every little thing outside of Qt. It contains docsets for a pile of languages and frameworks and lets you easily search across all or some of them instantly (and offline).

Qt Creator has a builtin help system which is great, but it only contains documentation for Qt. Quite often when writing Qt apps I find myself looking at documentation for other languages or frameworks as well such as Javascript, Android, iOS and of course C++. With Dash you can create a Search Profile containing exactly these docsets and you can activate this Profile whenever Qt Creator becomes the foreground app.


To make searching from Qt Creator as simple as possible, we can register Dash as an external tool by going to Preferences > Environment > External Tools. Dash registers a custom URL scheme with Mac OS X so we can open docs from the command line simply by using "open dash://QWidget". To emulate this behavior from Creator, we can add a new external tool like so:


The final step for documentation bliss is to register a key binding that automatically calls Dash with the currently selected text. From the same Environment page in Preferences, you can navigate to the Keyboard tab and enter the name of your external tool in the filter text. Next, simply record the key binding you like. As a big fan of the IDEA tools (Android Studio, WebStorm, etc.) I chose to use the same key binding that Dash uses in those tools which is cmd + shift + d, but to each his/her own.


That's it! Now you can select text in Qt Creator and use your key binding to jump directly to the docs for that selection.

Using Qt to build an Omi App for iOS (and Android)

Using Qt to build an Omi App for iOS (and Android)

Working on projects where the technology is pre-determined, it's often difficult to be able to deep-dive into familiar waters. Recently, we have been working on a new service called Omi - and in that context I was able to use two weeks to knock together a prototype of a mobile app for it using Qt and QML. With the help of QML, we were able to build a responsive and functional UX in less than two weeks What follows is a bit of a braindump of trips and ticks I found or discovered. For those expecting a more complete end-result, I apologise in advance; This is all I managed to cobble together before moving on to new projects...

Fly is now Open Source

It's a known fact that ninjas like open source. There are many good reasons for releasing your source code into the open, but in the end we do it because it feels right.


The Fly app was originally hacked up over a weekend in late 2010, but has been polished a bit since then (although there are still some rough edges here and there). The Qt version has been published in Ovi Store (both for Symbian and MeeGo) and Google Play (experimental) and we've had some pretty good download numbers, for a local app.

That's not to say that it's anywhere near perfect. There are lots of improvements that can be made. If you feel like improving it, the sky is the limit! (pun intended ;) ).

It has been a long time coming, but we have finally released the Fly source code as open source. You can clone the github repository here or browse the source code here. Happy hacking!
