<h1><span lang=EN-GB>Using Styles</span></h1>
<p class=MsoNormal><span lang=EN-GB style='color:black'>&nbsp;</span></p>
<p class=MsoNormal><span lang=EN-US>Sometimes graphical tools give the user the
possibility to freely change the graphical attributes to paint each shape
(color, line-width, &#8230;). &nbsp;But more often all shapes of the same kind
shall be painted in the same way.</span></p>
<p class=MsoNormal>For example in a Ecore editor it makes
sense, that all EClasses look identical. The user might still have the
possibility to change the color of a EClass, but then the color of all other
EClasses should be changed, too</p>
<p class=MsoNormal><span lang=EN-US>&nbsp;</span></p>
<p class=MsoNormal><span lang=EN-US>The graphics framework supports this by
providing &#8220;styles&#8221;. A style is a container for graphical attributes
(color, line-width, &#8230;), which can be associated by a graphics algorithm.
A style can have a parent-style, from which a style can &#8220;inherit&#8221;
graphical attributes (similar to cascading style sheets).</span></p>
<p class=MsoNormal><span lang=EN-US>Concretely the value of a graphical
attribute is determined by finding the first value which is not null in the
following order:</span></p>
<ol style='margin-top:0cm' start=1 type=1>
<li class=MsoNormal><span lang=EN-US>The graphics algorithm itself</span></li>
<li class=MsoNormal><span lang=EN-US>The style assigned to the graphics
algorithm, if style exists</span></li>
<li class=MsoNormal><span lang=EN-US>The parent-style(s) of the style, if
parent-style(s) exists</span></li>
</ol>
<p class=MsoNormal><span lang=EN-US>&nbsp;</span></p>
<p class=MsoNormal><span lang=EN-US>It has several advantages if the same style
is associated by many graphics algorithms:</span></p>
<ul style='margin-top:0cm' type=disc>
<li class=MsoNormal><span lang=EN-US>When a graphical attribute value of the
style is changed, all graphics algorithms are repainted using this new
style</span></li>
<li class=MsoNormal><span lang=EN-GB style='color:black'>A tool could provide
a predefined set of styles from which the user can choose (similar to the
&#8220;themes&#8221; available in many programs)</span></li>
<li class=MsoNormal><span lang=EN-GB style='color:black'>Redundant storage of
identical information is avoided</span></li>
</ul>
<p class=MsoNormal><span lang=EN-US>&nbsp;</span></p>
<h2><span lang=EN-GB>Creating a Style Utility Class</span></h2>
<p class=MsoNormal><span lang=EN-GB style='color:black'>&nbsp;</span></p>
<p class=MsoNormal><span lang=EN-GB style='color:black'>In this example we want
to associate the same style to the graphics algorithms of all EClasses. The
graphical attributes</span><span lang=EN-GB> </span><span lang=EN-US>(color, </span><span
lang=EN-GB style='color:black'>line-width, &#8230;) are then set on the style
and no longer on the different graphics algorithm.</span></p>
<p class=MsoNormal><span lang=EN-GB style='color:black'>Additionally we will
provide functionality to change the color-value of that style, and as a result
all EClasses will be painted in this color.</span></p>
<p class=MsoNormal><span lang=EN-GB style='color:black'>&nbsp;</span></p>
<p class=MsoNormal><span lang=EN-GB style='color:black'>We start by
implementing a utility class for the handling of styles.</span></p>
<p class=MsoNormal><span lang=EN-GB style='color:black'>We store the styles in
the diagram with a given ID. The utility class has methods to return a specific
style by either finding it in the diagram or by creating a new style and
assigning it to the diagram.</span></p>
<p class=MsoNormal><span lang=EN-GB style='color:black'>Note, that we have two
styles: one main style for all graphics algorithms of the EClass, and one child
style for the Text of the EClass. The reason is, that we want to have a
different color for the text and for the lines, but in both cases the color is
stored a &#8220;foreground&#8221; color.</span></p>
<p class=MsoNormal><span lang=EN-GB style='color:black'>&nbsp;</span></p>
<p class=MsoNormal><span lang=EN-GB style='color:black'>You can see the
complete implementation of the style utility class here:</span></p>
