prefuse.render.Renderer is drawing outside of the
reported bounds. In this case, there is usually a bug in the Renderer.
One reported problem arises from Java itself, however, which
inaccurately redraws images outside of their reported bounds. If you

Parameters:
f - the Font to use |
| setHighQuality | | public void setHighQuality(boolean on)(Code) | | Determines if the Display uses a higher quality rendering, using
anti-aliasing. This causes drawing to be much slower, however, and
so is disabled by default.
Parameters:
on - true to enable anti-aliased rendering, false to disable it |
| setItemSorter | | public synchronized void setItemSorter(ItemSorter cmp)(Code) | | Set the ItemSorter that determines the rendering order of the
VisualItems. Items are drawn in ascending order of the scores provided
by the ItemSorter.
the prefuse.visual.sort.ItemSorter to use |
| setRenderingHints | | protected void setRenderingHints(Graphics2D g)(Code) | | Sets the rendering hints that should be used while drawing
the visualization to the screen. Subclasses can override
this method to set hints as desired. Such subclasses should
consider honoring the high quality flag in one form or another.
Parameters:
g - the Graphics context on which to set the rendering hints |
| setSize | | public void setSize(int width, int height)(Code) | | Set the size of the Display.
Parameters:
width - the width of the Display in pixels
Parameters:
height - the height of the Display in pixels

| setTextEditor | | public void setTextEditor(JTextComponent tc)(Code) | | Sets the TextComponent used for on-screen text editing.
Parameters:
tc - the TextComponent to use for text editing |
| setTransform | | public synchronized void setTransform(AffineTransform transform) throws NoninvertibleTransformException(Code) | | Set the 2D AffineTransform (e.g., scale, shear, pan, rotate) used by
this display before rendering visual items. The provided transform
must be invertible, otherwise an expection will be thrown. For simple
panning and zooming transforms, you can instead use the provided
pan() and zoom() methods.
|
| setVisualization | | public void setVisualization(Visualization vis)(Code) | | Set the Visualiztion associated with this Display. This Display
will render the items contained in the provided visualization. If this
Display is already associated with a different Visualization, the
Display unregisters itself with the previous one.
Parameters:
vis - the backing Visualization to use. |
| stopEditing | | public void stopEditing()(Code) | | Stops text editing on the display, hiding the text editing widget. If
the text editor was associated with a specific VisualItem (ie one of the
editText() methods which include a VisualItem as an argument was called),
the item is updated with the edited text.
|
| zoom | | public synchronized void zoom(Point2D p, double scale)(Code) | | Zooms the view provided by this display by the given scale,
anchoring the zoom at the specified point in screen coordinates.
Parameters:
p - the anchor point for the zoom, in screen coordinates
Parameters:
scale - the amount to zoom by |
| zoomAbs | | public synchronized void zoomAbs(Point2D p, double scale)(Code) | | Zooms the view provided by this display by the given scale,
anchoring the zoom at the specified point in absolute coordinates.
Parameters:
p - the anchor point for the zoom, in absolute(i.e. item-space) co-ordinates
Parameters:
scale - the amount to zoom by |
