label

label is an HTML component that creates a caption for a component.

  • XML element: label

  • Java class: Label

Basics

The label component is applicable to native HTML components and can also serve as an alternative for the label attribute that is present in the majority of UI components in Jmix.

To set a label on a component, pass that component’s id to the setFor attribute of the label. For example, to set the label on a checkbox component:

<div>
    <checkbox id ="checkbox"/>
    <label text="Enable Notifications" setFor="checkbox"/>
</div>
label basic

Having the label associated with a component makes the label text correctly interpreted by assistive technologies, such as screen readers.

To add text that is not associated to a component, use the span or div components.

Dynamic Label

To dynamically set or update text in label, first specify its id attribute:

<label id="dynamicLabel" setFor="button"/>
<button id="button" text="Click"/>

Use this id to reference the label in the view controller and update the text with the setText() method:

@ViewComponent
private Label dynamicLabel;

@Subscribe("button")
public void onButtonClick(final ClickEvent<JmixButton> event) {
    dynamicLabel.setText("Button clicked " + event.getClickCount() + " times.");
}
label dynamic
