enter image description here

i trying find way increase folder/file name font size in jfilechooser. current idea have create custom jfilechooser, loop on elements , try increase font of folder names. thought i'd increase font of filepane, doesn't work. nothing happens. here code:

public class jfilechoosercustom extends jfilechooser {     public jfilechoosercustom() {         setfilechooserfont( this.getcomponents() );     }      public void setfilechooserfont( component[] comp ) {         for( int x = 0; x < comp.length; x++ ) {           // system.out.println( comp[x].tostring() );  // trying know type of each element in jfilechooser.           if(comp[x] instanceof container) setfilechooserfont(((container)comp[x]).getcomponents());            try{               if(comp[x] instanceof filepane) comp[x].setfont( comp[x].getfont().derivefont( comp[x].getfont().getsize() * 2f ) );           }           catch(exception e){}//do nothing         }     } }

i hope assist me this.

don't work filepane, use jlist , jtable instead (these components used filepane present file list).

import java.awt.component; import java.awt.container;  import javax.swing.jfilechooser; import javax.swing.jlist; import javax.swing.jtable; import javax.swing.swingutilities;  /**  * <code>increasefilechooserfont</code>.  */ public class increasefilechooserfont {      public static void main(string[] args) {         swingutilities.invokelater(new runnable() {              @override             public void run() {                 jfilechooser chooser = new jfilechooser();                 setfilechooserfont(chooser.getcomponents());                 chooser.showopendialog(null);                 system.exit(0);             }         });     }      public static void setfilechooserfont(component[] comp) {         (int x = 0; x < comp.length; x++) {             // system.out.println( comp[x].tostring() ); // trying know type of each element in jfilechooser.             if (comp[x] instanceof container)                 setfilechooserfont(((container) comp[x]).getcomponents());              try {                 if (comp[x] instanceof jlist || comp[x] instanceof jtable)                     comp[x].setfont(comp[x].getfont().derivefont(comp[x].getfont().getsize() * 2f));             } catch (exception e) {             } // nothing         }     } }
