In general, it’s an argument against writing code in XML. XML was really meant to be a machine to machine language, to make things like SceneBuilder easier to write :). People came second.

You really want to use a domain specific language that’s easy to read and write. QML is that. I find XML tags overwhelm the rest of the text making it hard to understand what’s going on, and hard to write unless you have a good XML editor.  QML has less cruft and it’s easier to see what’s happening with a quick glance.

Now, having said that, HTML seems to be pretty popular…

You said: "good declarative UI language, think QML not FXML".

What do you see as the advantages of QML over FXML?

GUI builders are great for prototyping or helping you learn. But when the
application gets complex I keep hearing developers throw them out. They
start getting in the way.

I think if you have a good API and a good declarative UI language, think
QML not FXML, then you may find you don¹t really need a GUI builder. How
may people are using GUI builders to create Web app UI¹s? Now web UIs are
simpler, but maybe that¹s the point.

And why not leave GUI builders to the tools vendors. They¹re hard to make
and get right, especially of you don¹t have a revenue model to support the
army of developers you need.


Hmm, I wonder what React Native would look like with JavaFX and NashornŠ
