Diagram Canvas BackgroundColor [message #215234]

Dear community,

I am trying to set the background of the editor canvas to some user
spedific function.
I can do this via the DiagramEditPart's methods setOpaque and set
BackgroundColor.

However the grid is only visible when set to "infront" and then really
in front of every other diagram element.

Whats the steps to get the grid shown but as the lowest layer, just like
when the DiagramEditPart is not set to opaque.

TIA & regards
Thomas

I managed to set the background color without any drawbacks of the
GMF/GEF-layers by settings the GrahpicalViewer's Control background to
the color i desire.

I added the following method
/**
* dynamic template content

* @generated
*/
protected void createGraphicalViewer(Composite parent) {
super.createGraphicalViewer(parent);
org.eclipse.swt.graphics.RGB rgb = PreferenceConverter.getColor(
HmiDiagramEditorPlugin.getInstance().getPreferenceStore(),
HMIUIMessages.Id_Pref_CanvasBackground);
if (!rgb.equals(ColorConstants.white.getRGB())) {
getGraphicalViewer().getControl().setBackground(
new Color(null, rgb));
}
}

to the generated XXXDiagramEditor and it does the trick.

Regards Thomas
