Hi Maik,
Well, I'm really not familiar with the UIManager stuff, so this is from quickly looking at the JavaDocs. the FontUIResource is a derived class from Font, similarly for ColorUIResource. Looking at the UIManager it treats the value differently if it is a 'UIResource' vs if it is the baseclass (Font, Color).
On first reading it appears that when the value is a UIResource it checks the parent component for the value. But I could easily be missing something.

Are you sure you want to use the 'UIResource' versions of these? I would suspect that you would want to just use Color/Font (since you want to override the parent).
what do you mean with 'UIResource versions' ? there are other versions too ? is there something wrong with my code ?
Font font = new Font("SansSerif", Font.PLAIN, 24); // only size shows an effect FontUIResource fontRes = new FontUIResource(font); UIManager.put("ToolTip.font", fontRes); UIManager.put("Tooltip.background", new ColorUIResource(Color.CYAN)); // shows no effect

I have a simple SVG document and want to receive MouseEvents in my Java code when a mouse click occurs on an element of the document. This works, as long as I have either a <desc> section or an <animateMotion ..> section in the document.
Do let the JSVGCanvas know that you want the document built as a 'dynamic' document? If you don't then without the 'desc' this will appear to be a totally static document[*], try:
canvas.setDocumentState(JSVGCanvas.ALWAYS_DYNAMIC);
[*] You may wonder why 'desc' makes it not 'totally static' the answer is because we support using 'desc' and 'title' elements as tool-tips when you hover over the associated content. In this case we disable desc and title for the root since they would always pop up and would be fairly annoying (although we still turn on the desc/title handling - always room for improvement).
I tried this even with the following sample from the W3C SVG sites, because I first thought that my document has been wrong.
<?xml version="1.0" standalone="no"?> <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" " http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd <http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd> "> <svg width="5cm" height="5cm" version="1.1" xmlns="http://www.w3.org/2000/svg";> <desc>Two groups, each of two rectangles </desc> <g id="group1" fill="red" > <rect x="1cm" y="1cm" width="1cm" height="1cm" /> <rect x="3cm" y="1cm" width="1cm" height="1cm" /> </g> <g id="group2" fill="blue" > <rect x="1cm" y="3cm" width="1cm" height="1cm" /> <rect x="3cm" y="3cm" width="1cm" height="1cm" /> </g> <!-- Show outline of canvas using 'rect' element --> <rect x=".01cm" y=".01cm" width="4.98cm" height="4.98cm" fill="none" stroke="blue" stroke-width=".02cm" /> </svg>
I have added a mouse listener to the group1 with:
SVGGElement group1 = (SVGGElement)svgDocument.getElementById("group1"); group1.addEventListener("click", new MouseClickListener(), false);
If I remove <desc> section in the document, the mouse events do no longer arrive in my code. Does anyone have an idea about that ?
