Experimenting with KJSEmbed
Some time ago I came across a service by Merriam-Webster OnLine which offers audio prononciations of the english words additionally to its online dictionary. I think this is particularly useful when learning new words. However, it’s a bit laborious to click through the page, so I made a little script to simplify this yesterday.
I took it as an opportunity to play around with KJSEmbed, KDE’s ECMAScript bindings. The examples helped a lot. I have never been very comfortable with the JavaScript language, but the implementation was pretty straightforward and it took definitely less time than it would have with C++.
What confused me at first was the fact that Qt properties are not accessed with get- and set-methods like in C++. Instead they behave like public member variables. Sometimes it wasn’t really clear to me if the element I wanted to access is a property or if it is an ordinary “setter method” (e.g. QWidget.setEnabled(…))… Oh well, I guess I can live with that.
The script uses a Qt designer .ui file to describe the user interface, downloads the .wav files using KJSEmbed’s NetAccess and plays them using an embedded Kaboodle KPart.

Hi Sandro,
You can tell if something is a setter/getter or a property by checking if the set or get method is a slot. You can access pretty much any slot just as you would in C++. The properties that are provided are the same as the ones listed in the Qt docs for the object as a property.
Please feel free to send any feedback to the KJSEmbed ML (details of finding it are at the above URL).
Rich.
