<h1>Graphiti &quot;New and Noteworthy&quot; for Juno</h1>
<p>Last revised December 13, 2011</p>
<p>This document describes the new development topics that were
addressed during the milestones towards the release 0.9.0 within the
Juno release train.</p>

on implementing round-offs especially in the area of custom anchors
and styles.</td>

<tr id="bug 352542">
<td class="title"><a
href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=352542">Ease
use of styles</a></td>
<td class="content">To ease the usage of styles in Graphiti,
there are now new methods (createPlain...) in the creation service
for graphics algorithms that create graphics algorithms without any
attributes set; by that one can directly use styles to define the
properties of the graphics algorithms, without having to reset any
attributes.</td>
</tr>
<tr id="bug 357922">
<td class="title"><a
href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=357922">Documentation
on Styles</a></td>
<td class="content">The Graphiti tutorial has been reworked to
explain the styles concept in a better and deeper way; this affects
both the written version in the Eclipse help system and the tutorial
plugin that is part of the SDK download. The new documentation also
reflects the new styles related creation methods for graphics
algorithms as described in the Ease use of styles entry for M4.</td>
</tr>
<tr id="bug 328279">
<td class="title"><a
href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=328279">Decorators
for Connection Texts</a></td>
<td class="content">Graphiti now allows to add decorators to
connection texts that do not overlap the text itself. This was not
possible so far because decorators were added directly to the shape
which was in this case the text itself. Users can simply add
decorators to texts now and can now position them by the standard
means as they like and are used to in other shapes.</td>
</tr>
<tr id="bug 341224">
<td class="title"><a
href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=341224">Hiding
of Selection Tools</a></td>
<td class="content">It is now possible to hide the connection
tools from the palette of the diagram editor. There are 2 new
methods (isShowSelectionTool and isShowMarqueeTool) in the tool
behavior provider that allow clients to modify the standard behavior
and hide the selection tool and/or the marquee tool from the
palette.</td>
</tr>
<tr id="bug 347421">
<td class="title"><a
href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=347421">DefaultDeleteFeature
allows Access to setDoneChanges</a></td>
<td class="content">Subclasses of DefaultDeleteFeature can now
use the standard behavior to indicate that no changes have been made
while performing (or rather not performing) a delete operation. This
has been achieved by increasing the visibility of the method
setDoneChanges to allow clients to access and override it.</td>
</tr>
<tr id="bug 323351">
<td class="title"><a
href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=323351">Disabling
the Context Buttons</a></td>
<td class="content">End users of Graphiti editors can now
prevent that the context buttons will appear when hovering with the
mouse over a shape. This can be done permanently using a toolbar
button or by holding the Control key (Command key on OS X) while
moving the mouse.</td>
</tr>
<tr id="bug 349416">
<td class="title"><a
href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=349416">Alligned
FixPointAnchor and BoxRelativeAnchor</a></td>
<td class="content">The behaviour of FixPointAnchors and
BoxRelativeAnchors is now aligned, especially dragging a connection
from a FixPointAnchor now works as it did for BoxRelativeAnchors
already before. In the cause of processing this bug the coding on
Graphiti side was very much streamligned.</td>
</tr>
<tr id="bug 347144">
<td class="title"><a
href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=347144">Angle
of MultiText</a></td>
<td class="content">Until now MultiTexts could not be rotated
although the angle attribute could be set for them. Now the method
setAngle() has an impact in the graphical representation. The angle
is specified in degrees, 0 degrees corresponds to the 3 o'clock
position. A positive value indicates a clockwise rotation while a
negative value indicates a counter-clockwise rotation of the text.
The developer is responsible for the correct size and location of
the MultiLineText GA.</td>
</tr>
<tr id="bug 363229">
<td class="title"><a
href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=363229">Nested
Anchor Shapes</a></td>
<td class="content">Graphiti now supports drawing nested shapes
for representing anchors. These shapes can now be defined for
FixPointAnchors and BoxRelativeAnchors and are correctly rendered by
the framework.</td>
</tr>
<tr id="bug 355968">
<td class="title"><a
href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=355968">Bug
355968</a></td>
<td class="content">An issue in the calculation of the position
of FixPointAnchors and BoxRelativeAnchors caused a presentation
issue in some cases. This has been fixed and the anchors are
displayed at the correct location now in all cases.</td>
</tr>
<tr id="bug 352440">
<td class="title"><a
href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=352440">Bug
352440</a></td>
<td class="content">A bunch of warnings inside the Graphiti
framework coding has been removed, especially caused by the need to
be compatible with the Eclipse 3.6 version of GEF (3.6). Now
Graphiti switched to support a minimal version of GEF 3.7 (part of
Eclipse Indigo) at least and therefore was able to remove some GEF
deprecations warnings. Also some further warnings in Graphiti coding
have been removed.</td>

<td class="content">Graphiti is now source compatible with JDK
1.5. This was done to ease integration with some modeling projects
that use this Java version. Now users will be able to run the
Graphiti framework on top of Java 5</td>

numbers for diagrams; for older versions than 0.9.0 the Graphiti
diagram editor will perform an auto migration of the background
colour attribute of Text objects to correctly display the background
colour (this behaviour can be changed by the tool developer). For
details on this please have a look into the bug report. <b>Involves
diagram migration!</b>
