Hi guys,
I'm going crazy for 5 hours to comprise how can I change the font in the textLabel!!!

I wander across the network .. e-v-e-r-y-w-h-e-r-e!!!

The required parameter is named "TheFont" and It should be an integer. Really, What is it???Is It possible change the font's type or the font's size?I'm resigned!!

Help me please  

I haven't used controlP5 yet.
I looked at controlP5 : : Textlabel : : setFont ( ) and indeed the documentation here is a bit cryptic, referring to BitFontRenderer which can't be found on the current documentation...
Searching this one with Google gives only three references: the above reference page, somebody with this class in a stack trace on this forum, and the source itself!
Looking at the latter, I see that "BitFont" means bitmap font.
We have a constant defining the number of fonts to 4, various arrays relying on this number, and four hard-coded fonts:
standard58.gif
standard56.gif
synt24.gif
GrixelKyrou9.gif
(these are images).
In the jar I have (probably old), I see the first three fonts, two very small, one larger. Not the last one which might be in the latest versions.
All this to say:
- the parameter is an int because it refers to one of the built in fonts, so currently the number must be 0 to 3;
- you have no choice of font;
- well, actually you can use your own font: you must generate the corresponding bitmap file, change and recompile this class, and update the jar. Not super flexible, but possible.

I think sojamo should remove the reference to the BitFontRenderer in the public documentation and expand a bit more on what the parameter means.

Apparently you can use the following constants as font parameter:

ControlP5.standard58
ControlP5.standard56
ControlP5.synt24
ControlP5.grixel

hi there, i am working on quite a few updates at the moment which  also includes the font handling. bitfonts used by controlP5 will only be able to handle ascii characters ranging from 32-126. there will be a function that easily lets you add your own bitfont-template to the bitfontlist, PFont support will be in place with these updates, too.
some controllers have been updated, checkboxes are available, radiobuttons and checkboxes can be arranged in rows and columns, some controllers will be able use image textures.
the documentation still needs a revision, more examples will be added as well as tutorials/instructions showing how to create your own custom made controllers.
if you want to take a look at the current status, let me know i can pass you a copy - these updates are not ready for an official release yet.
best,
andreas

PFont support would be great!
