java - JFrame with custom border not showing controls -

i'm trying make own custom border, , have done through overriding paint function in jframe. problem have run into, fact paint being called after constructor, causing paint window on controls. because of this, table appears when happen click on in jframe. wondering if there way make paint function happen before constructor, or if there better way create custom border. here code:

public class guimain extends jframe {      int posx=0, posy=0;      jtable serverlist;      public guimain()     {         this.setundecorated(true);         this.setlayout(new gridbaglayout());          serverlist = new jtable(variables.servers, variables.serversheader);         add(serverlist);          this.addmouselistener(new mouseadapter(){             public void mousepressed(mouseevent e)             {                 posx = e.getx();                 posy = e.gety();             }         });         this.addmousemotionlistener(new mouseadapter(){             public void mousedragged(mouseevent evt)             {                 if(posy <= 20) {                     setlocation(evt.getxonscreen()-posx, evt.getyonscreen()-posy);                 }             }         });     }      public void paint(graphics g)     {         g.setcolor(new color(100, 100, 100));         g.fillrect(0,  0, main.width, main.height);          g.setcolor(new color(70, 70, 70));         g.fillrect(0,  0, main.width, 20);     } } 

any appreciated! thanks!

you know not safest thing do, overriding paint(...) of top-level window. type of "border" trying create? call super.paint(g);? myself, i'd create own class extended abstractborder class, , use border on jpanel jframe's contentpane.

for example,

which so:
