This example shows an undocumented feature of Panda’s GUI system: 9-slice scaling, which allows you to create themed buttons and frames that scale properly without the borders also getting stretched.

That… would have been rather useful to have known about before I implemented such a feature of my own! XD;
But this is quite impressive, and I’m glad to see that Panda supports it! 
(It might also be worth mentioning in the manual.)
@wolf: Does DirectGui Designer support this feature…? It seems like it could be a rather useful addition, if not!
Super useful feature. Definitely needs to be in the manual.
Now I want to know what other hidden features direct has. 
This is an interesting feature. I knew of those parameters but never what they actually were used for. Thank you for mentioning me and thanks @rdb for the nice example. This sure is worth a mention in the manual.
The DirectGui Designer does support most properties available on DirectGui widgets, those for the texture border are also included.
That is good to know–thank you!
