ImplementsAnimation, Editable, IconHolder, Iterable<Component>, StyleListener, TextHolder

A multi line label component that can be easily localized, this is simply based on a text area combined with a label.

Form hi = new Form("Test SpanLabel", BoxLayout.y());

Image icon = FontImage.createMaterial(FontImage.MATERIAL_INFO, "Label", 3.0f);

SpanLabel d = new SpanLabel("Default SpanLabel that can seamlessly line break when the text is really long.");
d.setIcon(icon);
SpanLabel l = new SpanLabel("NORTH Positioned Icon SpanLabel that can seamlessly line break when the text is really long.");
l.setIcon(icon);
l.setIconPosition(BorderLayout.NORTH);
SpanLabel r = new SpanLabel("SOUTH Positioned Icon SpanLabel that can seamlessly line break when the text is really long.");
r.setIcon(icon);
r.setIconPosition(BorderLayout.SOUTH);
SpanLabel c = new SpanLabel("EAST Positioned Icon SpanLabel that can seamlessly line break when the text is really long.");
c.setIcon(icon);
c.setIconPosition(BorderLayout.EAST);
hi.add(d).add(l).add(r).add(c);
hi.show();

Constructor details

SpanLabel

public SpanLabel()
Default constructor will be useful when adding this to the GUI builder

SpanLabel

public SpanLabel(String txt, String textUiid)
Constructor accepting default text and uiid for the text

Parameters

txt String
the text
textUiid String
the new text UIID

SpanLabel

public SpanLabel(String txt)
Constructor accepting default text

Method details

styleChanged

public void styleChanged(String propertyName, Style source)

Invoked to indicate a change in a propertyName of a Style

NOTE By default this will trigger a call to Container#revalidate() on the parent container, which is expensive. You can disable this behavior by calling CN.setProperty("Component.revalidateOnStyleChange", "false"). The intention is to change this behavior so that the default is to “not” revalidate on style change, so we encourage you to set this to “false” to ensure for future compatibility.

Parameters

propertyName String
the property name that was changed
source Style
The changed Style object

initUnselectedStyle

protected void initUnselectedStyle(Style unselectedStyle)
Can be overridden by subclasses to perform initialization when the unselected style is set to a new value.
