java - How to implement auto complete functionality in a cell in JTable? -
my jtable has cell editor implemented instance of defaultcelleditor(jcombobox) class. i've tried couple of different things (adding auto-completion support swing comboboxes ) still doesn't work.
1:
// jcombobox combo = new jcombobox(new object[] { "ester", "jordi", "jordina", "jorge", "sergi" }); autocompletedecorator.decorate(combo); defaultcelleditor celleditor = new defaultcelleditor(combo); tablecolumn column = mytable.getcolumnmodel().getcolumn(2); column.setcelleditor(celleditor); // 2:
// object[] elements = new object[] { "ester", "jordi", "jordina", "jorge", "sergi" }; jcombobox c = new jcombobox(elements); c.seteditable(true); autocompletesupport support = autocompletesupport.install(c, glazedlists.eventlistof(elements)); support.setselectstextonfocusgain(false); support.sethidespopuponfocuslost(false); support.setstrict(false); comboboxcelleditor combo = new comboboxcelleditor(c); tablecolumn column = mytable.getcolumnmodel().getcolumn(2); combotablecellrenderer renderer = new combotablecellrenderer(); column.setcellrenderer(renderer); column.setcelleditor(combo); // 3:
// object[] elements = new object[] { "ester", "jordi", "jordina", "jorge", "sergi" }; jcombobox combobox = new jcombobox(elements); combobox.seteditable(true); autocompletion ac = new autocompletion(combobox); ac.setstrict(false); defaultcelleditor celleditor = new defaultcelleditor(combobox); tablecolumn column = mytable.getcolumnmodel().getcolumn(2); column.setcelleditor(celleditor); // the problem facing user starts typing in combo box, comes out of editing mode, , preventing entering value.
no issue favorite autocomplete jcombobox / jtextfield, still there second choice use autocomplete jtextfield instead of autocomplete jcombobox,
