FontRenderContext

When instantiating a TextRenderer object the underlying FontRenderContext object is null.

I am experiencing an error when using the TextRenderer's public getCharWidth() method.

Apparently the code works in some cases in and in other cases a stack trace shows this error:

fontRenderContext never initialized!

The stack trace shows The GlyphProducer (another underlying object) failing on its getGlyphPixelWidth() method.

Anyone have a solution or workaround for this?

Hi

Which version of JOGL do you use? You can't get the char width very early. I'm looking at the source code...

Please fill a bug report, fontRenderContext is always set to null, getFontRenderContext() should be called here:

v2.3.1, I am not sure if it's really a bug or perhaps the way we are using it.

No it's a bug, there is a code path that attempts to use a font render context never assigned, it works when you ask the char width of an already cached character.

Please switch to JOGL 2.3.2. We only maintain the very latest version.

Hey man,

Would you mind submitting the bug report then?

You can take full credit for it, I don’t care – I am kind of a newb when it comes to this jogl stuff anyway.

I will buy you a couple of drinks if you are ever in my hood.

With kind regards,
