java - The content of JComboBox is displayed as a single string, not as separate items -


i using following tablecellrenderer in jtable. when click on jcombobox, see list of values single string (like this: [text1, text2]), not separate items. error?

    tablecolumn columncombobox = table.getcolumnmodel().getcolumn(5);         columncombobox.setcellrenderer(getrenderercombobox());      private tablecellrenderer getrenderercombobox() {         return new tablecellrenderer() {              private jcombobox<string> box = new jcombobox<string>();              @override             public component gettablecellrenderercomponent(jtable table, object value,                     boolean isselected, boolean hasfocus, int row, int column)              {                    box.removeallitems();                 (string q : employees[row].getqualification())                     box.additem(q);                 box.setbackground(isselected ? table.getselectionbackground() : table.getbackground());                 box.setforeground(isselected ? table.getselectionforeground() : table.getforeground());                 return box;             }         };     }

if want dropdown field in table, done here. then, part create jcombobox:

public void setupsportcolumn(jtable table,                                  tablecolumn sportcolumn) {         //set editor sport cells.         jcombobox combobox = new jcombobox();         combobox.additem("snowboarding");         combobox.additem("rowing");         combobox.additem("knitting");         combobox.additem("speed reading");         combobox.additem("pool");         combobox.additem("none of above");         sportcolumn.setcelleditor(new defaultcelleditor(combobox));          //set tool tips sport cells.         defaulttablecellrenderer renderer =                 new defaulttablecellrenderer();         renderer.settooltiptext("click combo box");         sportcolumn.setcellrenderer(renderer);     }

and if not want, content of dropdown-cell when hover mouse on cell, , elements nice in column, have use html-tags in string passing settooltiptext-method. this:

 //set tool tips sport cells.         defaulttablecellrenderer renderer =                 new defaulttablecellrenderer();         string newline = "<br>";         string tooltiptext = "<html>snowboarding"+newline+"rowing"+newline+"knitting"+newline+"speed reading"+newline+"pool"+newline+"none of above</html>";         renderer.settooltiptext(tooltiptext);         sportcolumn.setcellrenderer(renderer);

i found answer here: multi-line tooltips in java?
