hello..
i'm new and still learning netbeans..
i use netbeans as my mini project for my java course..

but here's what i dont understand..
i design using GUI..
i make black background...
when i click on preview design..
everything seems ok and it look exactly like what i want..

but the problem is when i run the project..
it shows native look.. in my case.. the 'metal' design look..
ts backgroud is grey in colour..

so please anybody help me to overcome this problem...

Thanx in advance..
