Constructor Detail

StringItem

public StringItem(String label,
                  String text)

Creates a new StringItem object with the given label and textual content. Either label or text may be present or null.

Parameters:

label - the Item label

text - the text contents

StringItem

public StringItem(String label,
                  String text,
                  int appearanceMode)

Creates a new StringItem object with the given label, textual content, and appearance mode. Either label or text may be present or null.

The appearanceMode parameter (see Appearance Modes) is a hint to the platform of the application's intended use for this StringItem. To provide hyperlink- or button-like behavior, the application should associate a default Command with this StringItem and add an ItemCommandListener to this StringItem.

Here is an example showing the use of a StringItem as a button:

     StringItem strItem =
         new StringItem("Default: ", "Set",
                        Item.BUTTON);
     strItem.setDefaultCommand(
         new Command("Set", Command.ITEM, 1);
     // icl is ItemCommandListener
     strItem.setItemCommandListener(icl);     

Parameters:

label - the StringItem's label, or null if no label

text - the StringItem's text contents, or null if the contents are initially empty

appearanceMode - the appearance mode of the StringItem, one of Item.PLAIN, Item.HYPERLINK, or Item.BUTTON

Throws:

IllegalArgumentException - if appearanceMode invalid

Since:

MIDP 2.0

Method Detail

getAppearanceMode

public int getAppearanceMode()

Returns the appearance mode of the StringItem. See Appearance Modes.

Returns:

the appearance mode value, one of Item.PLAIN, Item.HYPERLINK, or Item.BUTTON

Since:

MIDP 2.0

getFont

public Font getFont()

Gets the application's preferred font for rendering this StringItem. The value returned is the font that had been set by the application, even if that value had been disregarded by the implementation. If no font had been set by the application, or if the application explicitly set the font to null, the value is the default font chosen by the implementation.

Overrides:

getFont in class Item

Returns:

the preferred font to use to render this StringItem

Since:

MIDP 2.0

See Also:

setFont(javax.microedition.lcdui.Font)

getText

public String getText()

Gets the text contents of the StringItem, or null if the StringItem is empty.

Returns:

a string with the content of the item

setLabel

public void setLabel(String label)

Description copied from class: Item

Sets the label of the Item. If label is null, specifies that this item has no label.

It is illegal to call this method if this Item is contained within an Alert.

Overrides:

setLabel in class Item

Parameters:

label - the label string

See Also:

Item.getLabel()

setText

public void setText(String text)

Sets the text contents of the StringItem. If text is null, the StringItem is set to be empty.

Parameters:

setFont

public void setFont(Font font)

Sets the application's preferred font for rendering this StringItem. The font is a hint, and the implementation may disregard the application's preferred font.

The font parameter must be a valid Font object or null. If the font parameter is null, the implementation must use its default font to render the StringItem.

Overrides:

setFont in class Item

Parameters:

font - the preferred font to use to render this StringItem
