Example Code Dialog


Here is the code that creates the above dialog:

Example #1

 * The new default dialog class must be derived from DefaultNodeSettingsPane.
public class DemoNodeDialogPane extends DefaultNodeSettingsPane {
     * Instantiate and add all needed components here in the constructor.
     * (The suppress warnings is used to avoid compiler warnings from the
     * constructor with generic varargs.)
    DemoNodeDialogPane() {
        // following components are bordered
        createNewGroup("Group 1:"); 
        addDialogComponent(new DialogComponentString(new SettingsModelString(
                DemoNodeModel.STR, null), "Enter a string value:"));
        addDialogComponent(new DialogComponentNumber(new SettingsModelInteger(
                DemoNodeModel.INT, 3), "Enter an integer (1-17):", 1));
        addDialogComponent(new DialogComponentNumber(new SettingsModelDouble(
                DemoNodeModel.DBL, 3.0),
                "Enter a floating point number:", 0.1));
        // closes the prev group, opens a new one>
        createNewGroup("Group 2:"); 
        addDialogComponent(new DialogComponentBoolean(new SettingsModelBoolean(
                DemoNodeModel.BOOL, false), "Checkit or leave it:"));
        addDialogComponent(new DialogComponentStringSelection(
                new SettingsModelString(DemoNodeModel.STRSEL, null),
                "Your choice:", "First", "Second", "Third"));
        addDialogComponent(new DialogComponentColumnNameSelection(
                new SettingsModelString(DemoNodeModel.COLSEL, ""),
                "Select a column", 0, true, IntValue.class, DoubleValue.class));

This code adds 6 components grouped by two borders. All components following the createNewGroup(

Each component's constructor requires a new instance of a SettingsModel. The settings model expects a string identifier that it uses to store and load the value of the component, and a default value which it holds until a new value is loaded. Additional parameters are necessary, depending on the type of component (most require a string) that will be displayed in front of the component as label. For more details, please refer to the documentation on the specific component.
