Constructor Detail

ClockItem

public ClockItem(java.lang.String label)

Creates a new clock.

Parameters:

label - the label for the clock

ClockItem

public ClockItem(java.lang.String label,
                 Style style)

Creates a new clock.

Parameters:

label - the label for the clock

style - the style for the clock string etc

Method Detail

animate

public boolean animate()

Description copied from class: FakeCustomItem

Animates this item. Subclasses can override this method to create animations. The default implementation animates the background and the item view if present.

Overrides:

animate in class FakeStringCustomItem

Returns:

true when this item has been animated.

includeSeconds

public boolean includeSeconds()

Determines whether seconds should be appended to this clock view.

Returns:

true when seconds should be visualized

createCssSelector

protected java.lang.String createCssSelector()

Description copied from class: FakeCustomItem

Retrieves the CSS selector for this item. The CSS selector is used for the dynamic assignment of styles - that is the styles are assigned by the usage of the item and not by a predefined style-name. With the #style preprocessing command styles are set fix, this method yields in a faster GUI and is recommended. When in a style-sheet dynamic styles are used, e.g. "Form>p", than the selector of the item is needed.
This abstract method needs only be implemented, when dynamic styles are used: #ifdef polish.useDynamicStyles
The returned selector needs to be in lower case.

Overrides:

createCssSelector in class FakeStringCustomItem

Returns:

the appropriate CSS selector for this item. The selector needs to be in lower case.

initContent

protected void initContent(int firstLineWidth,
                           int lineWidth)

Description copied from class: FakeCustomItem

Initialises this item. The implementation needs to calculate and set the contentWidth and contentHeight fields. The implementation should take the fields preferredWidth and preferredHeight into account.

Overrides:

initContent in class FakeStringCustomItem

Parameters:

firstLineWidth - the maximum width of the first line

lineWidth - the maximum width of any following lines

See Also:

FakeCustomItem.contentWidth, FakeCustomItem.contentHeight, FakeCustomItem.preferredWidth, FakeCustomItem.preferredHeight

updateTime

public java.lang.String updateTime(java.lang.String hours,
                                   java.lang.String minutes,
                                   java.lang.String seconds)

Fills in specific formats for time - this can be adjusted using the clock-format CSS attribute.

Parameters:

hours - the hours

minutes - the minutes of the time

seconds - the seconds of the time

Returns:

the time adjusted by additional formats - e.g. "hh:mm:ss"

setStyle

Description copied from class: FakeCustomItem

Sets the style of this item.

Overrides:

setStyle in class FakeStringCustomItem

Parameters:

style - the new style for this item.

hideNotify

Description copied from class: FakeCustomItem

The default implementation of this method sets the isShown field to false.

Overrides:

hideNotify in class FakeStringCustomItem

showNotify

protected void showNotify()

Description copied from class: FakeCustomItem

Called by the system to notify the item that it is now at least partially visible, when it previously had been completely invisible. The item may receive paint() calls after showNotify() has been called.
