The only ways I could find to add a label with some text in libGDX were:
By generating bitmaps for the font and using their BitmapFont API's.
By creating different font sizes of the above on the fly by using the freetype API's.
Is there an easier way to simply put a label on the screen without having to supply any font files? For example, if I'm writing a native Android app, I just instantiate a TextView with some text and that's it. If there's no easy way like that in libGDX, are there any technical details as to why the developers behind libGDX did not make it so?

I want to evaluate Libgdx for my app. I want the following things to be possible with Libgdx:
The dynamic loading of images. (✔ Texture)
Cutting images. (✔ TextureRegion)
Support of the multiple screens. (✔ Screen)
Recognizing swinging to the right, left, up and down in a defined area. (✔ GestureDetector)
Nice to have:
Styling of buttons. (?)
Standard elements like lists, ScrollViews etc.(?)
SVG graphics rendering (?)
I am thinking about the three problems. I read that GestureDetector should be very slow (500ms) and that SVG graphics are not natively supported and rendered with extensions very slow.
My third concern is that I can't just style buttons the way I want them to, for example: enter image description here
I would like to know if my requirements can be solved with the LibGDX functions and if they are good and easy to use.
Thanks for your advice!
LibGDX comes with a sublibrary called Scene2D UI, which defines a bunch of standard UI widgets which can be styled with JSON. It comes with different Button classes and ScrollPane which are your ScrollView substitute.
Docs you might want for Scene2D UI:
https://github.com/libgdx/libgdx/wiki/Scene2d.ui For the widgets
https://github.com/libgdx/libgdx/wiki/Skin For styling the widgets
In regards to SVG rendering, best option is to render them to PNG files if you want to use LibGDX alone.
Also, you may want to look into TextureAtlas for managing all of your TextureRegions, as well as AssetManager for managing all the external resources in your app https://github.com/libgdx/libgdx/wiki/Managing-your-assets.
It's a good idea to compile all of your texture files into a single texture, so that not many textures have to be bound and unbound in OpenGL, so have a look at this https://github.com/crashinvaders/gdx-texture-packer-gui this will help you produce a TextureAtlas automatically.
I need to style nodes with SVG images but cannot make it work. I am using ImageNodeStyle and passing an SVG image to the constructor. However, applying this style to nodes has no effect. I tried using bitmap images and they work fine.
How do I enable SVG image support for node styling?
yFiles for JavaFX uses JavaFX as the rendering engine and JavaFX unfortunately does not directly support SVG images. You need to convert the SVG image into an image that JavaFX understands and then you will be able to use it with ImageNodeStyle.
Using WebViews would be another option, however this is a very heavyweight solution that does not scale very well for many SVGs. You can surely use for rendering a background SVG, but I would not use hundreds of instances to show simple SVG graphics for the visualization of nodes.
Take a look at this answer to a related SVG/JavaFX question: it proposes a solution to the generic problem, which should also work for this specific issue.
I'm creating a app in Unity which is quite text heavy. So far, all the text is handled through the OnGUI function. I think I'm going to run into problems later on.
So, is it possible to create text, (using true type fonts, not 3D text or bitmaps. Not using something from the assets store either!) without using OnGUI? If so, how do you make each of the text filds independent with different styles, positions & parents?
Check the AssetStore for 2D toolkit or NGui plugin, they are both great for Ui stuff
they contain nice ways to do gradients, fonts, and aligning to screen edges or parent handles
Another option would be Daikonforge:

The company I work for released a game using NGUI, not long ago, but we are switching to Daikonforge now, because it's deemed more Artist-friendly than NGUI.
I am currently working in XNA 4.0 trying to render a font that I got. The font is rendered with this:
spriteBatch.DrawString(this.font, this.text, new Vector2(10, 10), this.color);
But some of my letters gets blurry and low quality (See image)
I have tried to change the SamplerState of the GraphicDevice but that does not seem to improve anything.
-Update-
After testing one of the ideas were XNA would compress the text and in that case loosing quality i tried out to create my own font texture instead of generating one using a .spritefont. And then sending that into the contentloader, the results I managed to get was just slightly larger text but with the same artifacts.
See Image
And I was now wondering if the problem still can have to do with compressing problems or if there could be another issue making the font get a lower quality in the program compared to using it ouside the program.
The way I am currently loading my font is using
font= ContentManager.Load<SpriteFont>(FontPath);
It's because XNA uses compression for spritefonts. The possible workarounds are:
Use Nuclex framework, which includes an alternative font importer;
Make your own font texture, following the instructions from Shawn Hargreaves's blog;
In your SpriteFont definition, double the size of generated font, then draw it at half its size.
I am working on an application where I need to display color coded indicators. The standard colors will be red/amber/green, but I need to be able to pick any color (e.g. by hex value). The colors are updated dynamically by a script, based on data (dashboard style).
Are there libraries that could help me? I am thinking in particular about using svg or canvas graphics that the script could modify.
Note: the question has been rephrased to better explain the context.
