THE PREVIEW DOESN'T SHOW THE REAL LOOK OF THIS 3D-BUTTON! The animation has 146 frames.
This is some work from 2007 I could rescue from my broken harddrive .... I hope you like it ...
This 3D button is made as replacement for the default kmenu-icon that's in your kicker if you use the (SuSE-) kickoff for example.
YOU DO NOT NEED KBFX, you can install KICKOFF in any distro, but I don't know if the button is working fine then.
The size is 58x58 px and it will be scaled in any size, but it looks ugly, if it's scaled.
If you use a smaller kicker-size, I can upload a smaller version that'll look great, but smaller ones will not be scaled by the kicker!
I can't test if this button still works, because I don't use KDE since a long time anymore.
Rename the Kmenu_button_58x58_slow_anim.mng to kmenu_basic.mng, copy it to ~/.kde/share/apps/kicker/pics and restart the kicker.
There's no vertical and no flipped version at this moment ... have fun =)
