java - Fill a JComboBox with new values -


currently filling jcombobox that:

countrybox = new jcombobox(countrylist.toarray(new string[countrylist.size()]));

however, when using program countrylist changes , fill jcombobox differently. tried use action change jcombobox:

countrybox.addactionlistener(new actionlistener() {    countrybox = new jcombobox(countrylist.toarray(new string[countrylist.size()])); }

however, not change values. me seems countrybox prefilled data before. recommendations do?

i appreciate answer!

don't create new jcombobox, create new model

defaultcomboboxmodel model = new defaultcomboboxmodel(countrylist.toarray(new string[countrylist.size()])); countrybox.setmodel(model);

you create own comboboxmodel proxy current list, that's you.

take closer @ how use combo boxes more details

i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
