tool.I have a problem of inserting pictures using this function as below:

InputStream in = getClass().getResourceAsStream("map.gif");
Label nodeLabel1 = new Label("Node4", new
Image(getViewSite().getShell().getDisplay(), in));
final NodeFigure nodeFigure1 = new NodeFigure(nodeLabel1);
panel.add(nodeFigure1, BorderLayout.CENTER);

This is the function that I found but seem like not working. Do you have
other suggestion in term to insert pictures? Thanks...

Are you adding the label to nodeFigure1 somewhere? What is NodeFigure's
layout?

Here is the NodeFigure's code ...

public class NodeFigure extends Figure {

public NodeFigure(Label name) {
ToolbarLayout layout = new ToolbarLayout();
layout.setMinorAlignment(ToolbarLayout.ALIGN_TOPLEFT);
layout.setStretchMinorAxis(false);
layout.setSpacing(2);
setLayoutManager(layout);
add(name);
}
}

thanks in advance ...

Try setting some text on the label (or maybe a LineBorder) and see if it's
visible. Maybe the problem is with loading the image.

I'm assuming that the image is not blank or transparent and that you're
properly loading it (you might want to double-check that by using an image
that already exists elsewhere in the workbench).

What do you see? Do you see space allocated for the Image? Can you please
attach a screenshot (with a red LineBorder around the label)?

Keep in mind that you have a ToolbarLayout located centrally inside a
BorderLayout. So, if the ToolbarLayout doesn't get enough height, part of
it will be hidden. Make the panel larger to see if it reveals anything.
What layout does it have?

I am not clear abt why my application window can display the .gif picture
but not to plugin project.Is that different mechanism to implement it?
The node text alone is visible but if i include with image together, the
error "An error has occurred when creating this view" came out when
running the pugin project.

plugin code:
InputStream in = getClass().getResourceAsStream("map.gif");
Label nodeLabel1 = new Label("Node4", new
Image(getViewSite().getShell().getDisplay(), in));
final NodeFigure nodeFigure1 = new NodeFigure(nodeLabel1);
panel.add(nodeFigure1, BorderLayout.CENTER);

I get stucked here.Or i calling the wrong image method..
Thanks...

Probably. Look at what exception is logged in the error log. That will
tell you what the problem is.

Try creating your Image like this and see if that works:

Image img = new Image(null, ImageDescriptor.createFromFile(getClass(),
"map.gif").getImageData());

This is assuming that the file map.gif is in the same package as the class
which invokes the above code.
