java - How to apply JTatto themes on JFrame using Swing -

i trying apply jtatto , feel in swing project.

the theme being applied on forms on others controls aren't working properly. overlapping on top of each other.

to apply theme using following code

try {   string lookandfeel="com.jtattoo.plaf.smart.smartlookandfeel";   uimanager.setlookandfeel(lookandfeel);  }  catch(exception ex) {  ex.printstacktrace(); } 

• works expecting

• l&f must be

  1. initialized before gui creations

  2. for changes on runtime, applied top-level containers calling swingutilities.updatecomponenttreeui(component c), simpler component c == local variable top-level container, otherwise have iterating , apply each of jcomponents separatelly, in current components tree
