Constructors

ListItem

  public ListItem()

Constructs an empty ListItem.

Methods

  public Object clone()

Clones the ListItem. ListView adds addtional rows by cloning its prototype ListItem. Note that if you have setData() on the prototype ListItem, clone() does not clone the data (all ListItem clones will reference the same data).

Overrides:

clone in class Object

  public ListView listView()

Returns the ListView associated with the ListItem. Returns null if the ListItem is not in a ListView.

  public boolean isTransparent()

Returns true if the ListItem is transparent, allowing ListView to optimize its drawing. ListView only draws the background of transparent ListItems.

  public void setCommand(String newCommand)

Sets the command associated with this ListItem. ListView sends ListItem's command instead of its own when the ListItem is single-clicked.

  public String command()

Returns the command associated with this ListItem.

See Also:

setCommand

  public void setTitle(String aString)

Sets the title the ListItem displays.

  public String title()

Returns the title the ListItem displays.

See Also:

setTitle

  public void setSelected(boolean flag)

Called by ListView when a ListItem is selected. By default, selected ListItems highlight by painting a white background.

  public boolean isSelected()

Returns true if the ListItem is selected.

See Also:

setSelected

  public void setEnabled(boolean flag)

Enables or disables the ListItem. Disabled ListItems cannot be selected, and render their title using Color.gray.

  public boolean isEnabled()

Returns true if the ListItem is enabled.

See Also:

setEnabled

  public void setImage(Image anImage)

Sets the Image the ListItem displays next to its title.

See Also:

setSelectedImage

  public Image image()

Returns the Image the ListItem displays next to its title.

See Also:

setImage

  public void setSelectedImage(Image anImage)

Sets the Image the ListItem displays next to its title when selected.

  public void setFont(Font aFont)

Sets the Font the ListItem uses to render its title.

  public Font font()

Returns the Font the ListItem uses to render its title. If no Font has been set, returns Font.defaultFont().

See Also:

defaultFont

  public void setSelectedColor(Color color)

Sets the color the ListItem uses to draw its background when selected.

  public Color selectedColor()

Returns the color the ListItem uses to draw its background when selected.

  public void setData(Object data)

Sets the ListItem's data, a storage place for arbitrary data associated with the ListItem.

  public Object data()

Returns the ListItem's data.

See Also:

setData

  public int minWidth()

Returns the minimum width required to display the ListItem's title and Image, if any.

  public int minHeight()

Returns the minimum height required to display the ListItem's title and Image, if any.

  protected void drawBackground(Graphics g,
                                Rect boundsRect)

Called from drawInRect() to draw the ListItem's background. Subclasses can override this method to draw custom backgrounds.

  protected void drawStringInRect(Graphics g,
                                  String title,
                                  Font titleFont,
                                  Rect textBounds,
                                  int justification)

Called from drawInRect() to draw the ListItem's title. Subclasses can override this method to draw the title string in a special way.

  public void drawInRect(Graphics g,
                         Rect boundsRect)

Called by ListView to draw the ListItem. If the ListItem is transparent, its ListView will have already drawn its background. If not, the ListItem should entirely fill boundsRect.
