FontAwesomeFX 8.0.7/8.0.8 released

UPDATE: In 8.0.7 I forgot to replace the TTF! So 8.0.7 still contains the 4.0.1 font. Some icons may not be displayed with 8.0.7. Have fixed this issue with fontawesomefx-8.0.8.

NavigationButtonsI have updated FontAwesomeFX and released version 8.0.7.
A few days ago the FontAwesome 4.1.0 was released with 70+ additional icons (FontAwesome now contains 439 icons).

“somehow more organic”: how to create a ‘noisy’ gradient in JavaFX

If you always wondered why some regions on your Mac, Websites or in your Smartphone-Apps look somehow more organic than a plain coloured area or even an region with a gradient, have a closer look!
Zooming into these areas shows that they are a bit “noisy”.

This effect can be created very easily with CSS in JavaFX too:
I just noticed that “-fx-background-image” is painted in front of “-fx-background-color“:


So, what is needed is a transparent “noise texture” which can be created here or here.

This texture is then used as a repeated background-image and painted in front the background-color which in JavaFX-CSS can also be a linear gradient:

-fx-background-color: linear-gradient(rgb(224,228,233) 0%, derive(rgb(224,228,233),-20%) 100%);
-fx-background-image: url("images/noise-texture.png");
-fx-background-repeat: repeat;  

I used this approach e.g in my MQTT.fx-UI:


MQTT.fx 0.0.2

A new version of MQTT.fx is available and I have polished the pre-alpha version and added some new features to MQTT.fx.

Controls to connect to the broker and to subscribe to topics are now placed in the header:


“Connection Options” can be reached from here:


“Publish” and “Receive” are place in one tab:


I have added an option to enable notifications on received messages:


AND NEW: “Arrived Messages” are collected in a separate tab with one color by topic.
The related messaged are colored accordingly thus they can be easily identified:


Also I found out an easy way to apply a noise and gradient effect via CSS like this:

Now that MQTT is on its way to become THE industry-standard protocol for IoT and M2M communication the IoT community might have to review current message strategies.

Isn’t it a very good way to start with a JavaFX-Client to get into MQTT ;-)?
So, currently I am working on JavaFX based frontend based on Eclipse Paho.

Featured so far:

  • connect to an MQTT broker (tested with mosquitto yet)
  • modify some connection options
  • subscribe to topics
  • publish to topics
  • continuous logging of arrived messages
  • load and save settings (working directory: [user.home]/mqttfx)
  • an ugly application icon
