#1

Hi, I am trying to add addDialogComponent dynamically after changing the value in the dropdown.

As of now code is working but it not reflecting, I have to manually minimize and maximize it too see the changes, and also it is updating not adding.

Please suggest

Hi @Ripul,

You need to call the repaint method on the Panel of the added Dialogcomponent, to update the dialog window after you have done the changes:

DialogComponentBoolean b = new DialogComponentBoolean(booleanModel, "label");
b.getComponentPanel().repaint();

Gabriel

Or you add the dialog component right away and set it visible when needed.

DialogComponentGridTableOne dialogComponentGridTableOne = new DialogComponentGridTableOne(
new SettingsModelString("Name ", "Table Name "));
dialogComponentGridTableOne.getComponentPanel().setVisible(true);

		addDialogComponent(dialogComponentGridTableOne);

Hi i tried the below code

addDialogComponent(new DialogComponentGridTableOne(new SettingsModelString("Name ", "Table Name ")));

		DialogComponentBoolean b = new DialogComponentBoolean(new SettingsModelBoolean(DemoNodeModel.BOOL, true), "Table Name ");
		b.getComponentPanel().repaint();

@Ripul,

here’s an example how it can be done.

final class ExampleDialog extends DefaultNodeSettingsPane {
    ExampleDialog() {
        final DialogComponentString diaComp =
            new DialogComponentString(new SettingsModelString("foo", "hello world"), "42");

        final DialogComponentBoolean visTrigger =
            new DialogComponentBoolean(new SettingsModelBoolean("bar", true), "Set visible");

        visTrigger.getModel().addChangeListener(e -> diaComp.getComponentPanel()
            .setVisible(((SettingsModelBoolean)visTrigger.getModel()).getBooleanValue()));

        addDialogComponent(visTrigger);
        addDialogComponent(diaComp);
    }

}

Best
Mark
