java - Linking renderer that displays a jComboBox to a cell in the jTable -
the problem is, when user clicks on cell style of line, , chooses 1 of 4 options , after clicks on other cell line style, after that, other cell displays line style, choosen in previous selected cell. how to, make line style unique every cell (different line styles in different cells) in "line style" column? cells in "line colour" column works fine , implemented similarly.
here sscce:

ok, i've solved problem. replacement "unique" combobox every cell. works, works fine, after modification in tablecelllineeditor class:
import java.awt.basicstroke; import java.awt.component; import java.awt.event.actionevent; import java.awt.event.actionlistener; import javax.swing.abstractcelleditor; import javax.swing.jcombobox; import javax.swing.jtable; import javax.swing.table.tablecelleditor; public class tablecelllineeditor extends abstractcelleditor implements tablecelleditor, actionlistener { jcombobox combobox; private basicstroke val; protected static final string edit = "edit"; public tablecelllineeditor() { combobox = new jcombobox(linestyle.values()); combobox.setrenderer(new listcelllinerenderer()); combobox.setactioncommand(edit); combobox.addactionlistener(this); } @override public object getcelleditorvalue() { return (basicstroke) ((linestyle) combobox.getselecteditem()).getstroke(); } @override public component gettablecelleditorcomponent(jtable table, object value, boolean isselected, int row, int column) { val = (basicstroke) value; (int = 0; < linestyle.values().length; i++) { if (val.equals(((basicstroke) (linestyle.values()[i]).getstroke()))) { combobox.setselecteditem(linestyle.values()[i]); } } return combobox; } @override public void actionperformed(actionevent e) { if (edit.equals(e.getactioncommand())) { val = (basicstroke) ((linestyle) combobox.getselecteditem()).getstroke(); fireeditingstopped(); } else { val = (basicstroke) combobox.getselecteditem(); } } } thank all, suggestions, , answers :)
