java color

Classic Servoy
1

I would like to set the color properties of a bean through a script. Unfortunately the bean wants a java color like ‘new Color()’…

Can anybody tell me how to archieve this?

try this:

var jcolor = new java.awt.Color(255,0,255);
elements.mybean.backgroundColor = jcolor

Jan, when I do this

var jcolor = new java.awt.Color(10,10,10);
elements.seperator.background = jcolor;

the message is: java.lang.IllegalArgumentException: Color parameter outside of expected range: Red Green Blue

When I do this:

var jcolor = new java.awt.Color(0,0,0);
elements.seperator.background = jcolor;

The result is a black line but any other thing than 0,0,0 will give an error…

It seems to use the float variant constructor… which accept 0.0-1.0
you could try this:

var jcolor = new java.awt.Color(parseInt(10),parseInt(10),parseInt(10)); 
```to make sure the integer variant is used.

Nope, but you gave me a direction. We have to use a floating value here so it is going to be:

var jcolor = new java.awt.Color(0.04, 0.04, 0.04);

The value lies between 0 and 1…

Jan, does this mean that we can call more java functions methods etc from within Servoy?

Thanks

yes, but be careful, it easy to create mem leaks

globals.frame = new javax.swing.JFrame('test frame');
globals.frame.setVisible(true);

creates a instant mem leak if you don’t clear globals.frame afterwards with:

globals.frame = null;

we strongly recomment to stick with JavaScript, unless you are an expirienced Java programmer

You must have read my mind because your code is exactly what I was experimenting with 8)

(unfortunately I receive an error on the use javax, not recognized!)

And yes, I will be carefull. So in fact it would be better to do this in a plugin?

For Java plugins are prefered.
