All Implemented Interfaces:

Cloneable, SwingConstants, TabableView

Enclosing class:

ImageView

private class ImageView.ImageLabelView

extends InlineView

ImageLabelView is used if the image can't be loaded, and the attribute specified an alt attribute. It overriden a handle of methods as the text is hardcoded and does not come from the document.

Method Detail

reset

public void reset(String text)

paint

public void paint(Graphics g,
                  Shape a)

Description copied from class: GlyphView

Renders a portion of a text style run.

Overrides:

paint in class GlyphView

Parameters:

g - the rendering surface to use

a - the allocated region to render into

getText

public Segment getText(int p0,
                       int p1)

Description copied from class: GlyphView

Fetch a reference to the text that occupies the given range. This is normally used by the GlyphPainter to determine what characters it should render glyphs for.

Overrides:

getText in class GlyphView

Parameters:

p0 - the starting document offset >= 0

p1 - the ending document offset >= p0

Returns:

the Segment containing the text

getStartOffset

public int getStartOffset()

Description copied from class: GlyphView

Fetches the portion of the model that this view is responsible for.

Overrides:

getStartOffset in class GlyphView

Returns:

the starting offset into the model

See Also:

View.getStartOffset()

getEndOffset

public int getEndOffset()

Description copied from class: GlyphView

Fetches the portion of the model that this view is responsible for.

Overrides:

getEndOffset in class GlyphView

Returns:

the ending offset into the model

See Also:

View.getEndOffset()

breakView

public View breakView(int axis,
                      int p0,
                      float pos,
                      float len)

Description copied from class: GlyphView

Breaks this view on the given axis at the given length. This is implemented to attempt to break on a whitespace location, and returns a fragment with the whitespace at the end. If a whitespace location can't be found, the nearest character is used.

Overrides:

breakView in class GlyphView

Parameters:

axis - may be either View.X_AXIS or View.Y_AXIS

p0 - the location in the model where the fragment should start it's representation >= 0.

pos - the position along the axis that the broken view would occupy >= 0. This may be useful for things like tab calculations.

len - specifies the distance along the axis where a potential break is desired >= 0.

Returns:

the fragment of the view that represents the given span, if the view can be broken. If the view doesn't support breaking behavior, the view itself is returned.

See Also:

View.breakView(int, int, float, float)

getForeground

public Color getForeground()

Description copied from class: LabelView

Fetches the foreground color to use to render the glyphs. This is implemented to return a cached foreground color, which defaults to null.

Overrides:

getForeground in class LabelView

Returns:

the cached foreground color
