i utilize jcombobox in program, i've changed foreground , background colors there bluish box surrounds text when hasn't focus. utilize netbeans , didn't find alternative disable it.

does know how do?

thanks in advance.

by appearance of it, border drawn metal , feel. don't know how disable it, think should alter color same grayness you're using rest of combo box, invisible:

((javax.swing.plaf.metal.metallookandfeel)uimanager.getlookandfeel()) .setcurrenttheme(new javax.swing.plaf.metal.oceantheme() { @override protected javax.swing.plaf.coloruiresource getsecondary2() { homecoming new javax.swing.plaf.coloruiresource(0x8b8b8b); } });
