Constructor Detail

AbstractUiWidgetImage

public AbstractUiWidgetImage(UiContext context,
                             ADAPTER widgetAdapter)

The constructor.

Parameters:

context - is the context.

widgetAdapter - is the widget adapter. Typically null for lazy initialization.

Method Detail

initializeWidgetAdapter

protected void initializeWidgetAdapter(ADAPTER adapter)

This method is called from AbstractUiWidgetNative.getWidgetAdapter() to initialize the UiWidgetAdapter. All attributes of this widget need to be set in the UiWidgetAdapter.

Overrides:

initializeWidgetAdapter in class AbstractUiWidgetNative<ADAPTER extends UiWidgetAdapterImage,Void>

Parameters:

adapter - is the UiWidgetAdapter to initialize.

setUrl

private void setUrl(ADAPTER adapter)

Parameters:

adapter - is the widget adapter.

getUrl

public String getUrl()

This method gets the URL of this object. The URL can be absolute or relative (a path relative to the current base URL).

Specified by:

getUrl in interface AttributeReadUrl

Returns:

the URL or null if NOT set.

setUrl

public void setUrl(String url)

This method sets the URL of this object.

Specified by:

setUrl in interface AttributeWriteUrl

Parameters:

url - is the new URL.

getAltText

public String getAltText()

This method gets the alternative text of this object. This text is used to provide the essential information of an object in textual form. E.g. if an image can NOT be displayed because it is missing, the alternative text is displayed instead. Further, accessibility tools such as screen-readers can use this information to help the user in order to better understand the meaning of an object.

Specified by:

getAltText in interface AttributeReadAltText

Returns:

the alternative text or null if NOT set.

setAltText

public void setAltText(String altText)

This method sets the alternative text of this object.

Specified by:

setAltText in interface AttributeWriteAltText

Parameters:

altText - is the new alternative text.
