Constructor Detail

NumberTextFigure

public NumberTextFigure()

Method Detail

overlayColumns

public int overlayColumns()

Gets the number of columns to be used by the text overlay.

Specified by:

overlayColumns in interface TextHolder

Overrides:

overlayColumns in class TextFigure

See Also:

FloatingTextField

getValue

public int getValue()

Gets the numerical value of the contained text. return the value or 0 in the case of an illegal number format.

setValue

public void setValue(int value)

Sets the numberical value of the contained text.

getRepresentingFigure

public Figure getRepresentingFigure()

Usually, a TextHolders is implemented by a Figure subclass. To avoid casting a TextHolder to a Figure this method can be used for polymorphism (in this case, let the (same) object appear to be of another type). Note, that the figure returned is not the figure to which the TextHolder is (and its representing figure) connected.

Specified by:

getRepresentingFigure in interface TextHolder

Overrides:

getRepresentingFigure in class TextFigure

Returns:

figure responsible for representing the content of this TextHolder
