Employment/Purpose

A specific tab. Clicking on the tab brings the tab panel to the front. You could put a label and an image on it by label and image properties.

Example

Closable

By setting the closable property to true, a close button is shown on a tab, such that a user could close the tab and the corresponding tab panel by clicking the button. Once a user clicks on the close button, an onClose event is sent to the tab. It is processed by the onClose method of Tab. Then, onClose, by default, detaches the tab itself and the corresponding tab panel.

Dynamically-created Tab

Since  7.0.0

If you assign a model to a Tabbox, it will do nothing for an onClose event. Therefore, developers have to listen an onClose event to remove the corresponding item in the model instead of Tab itself.

When using model, Tabs are dynamically created, so you can't just listen to onClose event like @Listen("onClose = tab") because a Tab is not created when wiring a listener. You can forward onClose event to its parent like:

<tabbox id="tabbox">
    <template name="model:tab">
        <tab closable="true" forward="onClose=tabbox.onTabClose(${each})"/>
    </template>
