Method Detail

reload

public void reload()

getApplication

protected Application getApplication()

Returns the user's application instance, cast to its specific type.

createHeader

public Component createHeader(java.lang.String appName)

setContent

public void setContent(Component c)

Description copied from interface: Layout

When navigating from one screen to another, the application calls EchoSupport.setScreen() (EchoSupport#setScreen(Component)) and this triggers among other things this method on your Layout component. The typical implementation would be to replace a sub component of your Layout with the new content component .

It is important to realize that this new content component is actually the screen that the user code is currently setting with setScreen, so it will typically be an instance of a subclass of the AbstractScreen class.

getContent

public Component getContent()

Description copied from interface: Layout

Retrieves the current content component last set by setContent(). Basically retrieves the Screen that was assigned as current screen to your Layout component.

addOnLoadScriptOnce

public void addOnLoadScriptOnce(java.lang.String javaScriptExecutedOnceOnWindowLoad)

Description copied from interface: Layout

Often it is handy to send some javascript to the client browser for execution on the onLoad event of the page. Examples of this include opening a popup that visualizes a URL outside of the application.

It is important to realize that the script(s) set via the method must only execute in the next rendering of the screen, and not in subsequent renderings.

A convenient way of satisfying this operation is adding an instance of OnLoadScriptOnceComponent.

getFont

public Font getFont()

Returns the default font.

Specified by:

getFont in interface Component

Overrides:

getFont in class AbstractComponent

Returns:

The font of the component.

setFont

public void setFont(Font font)

Sets the default font.

Specified by:

setFont in interface Component

Overrides:

setFont in class AbstractComponent

Parameters:

font - The new font of the component.

getForeground

public Color getForeground()

Returns the default text color.

Specified by:

getForeground in interface Component

Overrides:

getForeground in class AbstractComponent

Returns:

The foreground of the component.

setForeground

public void setForeground(Color foreground)

Sets the default text color.

Specified by:

setForeground in interface Component

Overrides:

setForeground in class AbstractComponent

Parameters:

foreground - The new foreground color of the component.

getTitleFont

public Font getTitleFont()

Returns the font of the title.

setTitleFont

public void setTitleFont(Font titleFont)

Sets the font of the title.

getTitleForeground

public Color getTitleForeground()

Gets the color of the title text.

setTitleForeground

public void setTitleForeground(Color titleForeground)

Sets the color of the title text.

getTitleBackground

public Color getTitleBackground()

Gets the background color for the title.

public void setTitleBackground(Color titleBackground)

Sets the background color for the title.

setHeaderHeight

public void setHeaderHeight(int heightInPixels)

Sets the height of the header, in pixels.

getHeaderHeight

public int getHeaderHeight()

Gets the height of the header, in pixels.

setTitleOffset

public void setTitleOffset(int heightInPixels)

getTitleOffset

public int getTitleOffset()

applyStyle

public void applyStyle(Style style)

Description copied from interface: Component

Sets stylistic properties of this component based on a Style object. The version of this method in Component will set foreground and background colors and the font from the style if they are present. Components should override this method if they allow more properties to be set from a style object, and should call super.applyStyle() if necessary.

Specified by:

applyStyle in interface Component

Overrides:

applyStyle in class ContentPane

Parameters:

style - The style object from which to retrieve properties for this Component.

See Also:

Component.applyStyle(Style)

setErrors

public void setErrors(java.util.List errorsAfterTranslation)

Description copied from interface: Layout

Sets the current list of errors. It is your duty to visualize all of the strings in this List to the users. Any i18n translation, parametrization and removing of duplicate messages will have been done for you.

setMessages

public void setMessages(java.util.List messagesAfterTranslation)

Description copied from interface: Layout

Sets the current list of messages. It is your duty to visualize all of the strings in this List to the users. Any i18n translation, parametrization and removing of duplicate messages will have been done for you.

setWarnings

public void setWarnings(java.util.List warningsAfterTranslation)

Description copied from interface: Layout

Sets the current list of warnings. It is your duty to visualize all of the strings in this List to the users. Any i18n translation, parametrization and removing of duplicate messages will have been done for you.
