Different options to specify label position around border node [message #1701606] Tue, 14 July 2015 11:51 Go to next message

Hello,

I was wondering if there are further options than the ones provided in the "Label" tab of a "Style" Mapping element on viewpoint specification level.

See this screenshot:
index.php/fa/22497/0/
Here it seems like there is only the possibility to set the "Label Position" to "border" or "node", but nothing like left, right, top, bottom.


I am looking for options that for example an end user has who is working with such a diagram. For example:
- Position a label on top, right, left, under a border node

See this screenshot:
index.php/fa/22498/0/
Here the label "BorderNode1" is in the default position and the label "BorderNode2" was moved to the left hand side of the border node manually.

Regards,
Benjamin.

Hello,

Indeed currently you are not able to specify the label position in the
GMF. You will have to follow the documentation about how to provide a
custom style [1].
Note that in your case the customization will be quite light. First you
will need to add an extension point on
"org.eclipse.sirius.diagram.ui.styleConfigurationProvider" to provide
your own "IStyleConfigurationProvider".
In your class implementing IStyleConfigurationProvider, implement
"provides", to return true for your mapping, and
"createStyleConfiguration" to return your own SimpleStyleConfiguration
for your mapping.
In your class extending SimpleStyleConfiguration, override
getNameBorderItemLocator to return a BorderItemLocator set on your
prefered side.
Example for a label always located on the west border:
public IBorderItemLocator getNameBorderItemLocator(DNode node,
IFigure mainFigure) {
BorderItemLocator locator = new BorderItemLocator(mainFigure,
PositionConstants.WEST);
return locator;
}

Regards,
Steve
