[Interest] automatic UI updates as the result of QML file modifications

[Joshua Kolden]

Yes.  I’ve done this.  I have a realtime coding environment in which the running app will reload and redraw qml on file change.  It’s relatively easy to setup.  I’ve even set it up so that it’ll draw iPad and iPhone sized windows next to a reduced desktop window on my mac desktop machine.

The basics are that I use a QFileSystemWatcher to notice a qml file change and signal to reload the qml.  The only extra step is to call clearComponentCache() on the qml engine each time before reloading the qml.

javascript files also need to be updated in my case because I’m using coffeescript, so there is a compile step required before loading.  For this I use “guard” (ruby file watcher gem, but you could use anything).  It watches for any changes to the caffescript files, and runs make to build the js.

I do all my development in ram disk, so the combined effect is a completely interactive real time text driven design interface.  I really recommend it.
