Style with LineWidth and LineStyle does not work [message #727579]

Hi,

i tried to use my own style (same way like the tutorial proposes):

public static Style getStyleForGroup(Diagram diagram) {
	final String styleId = "group";

	Style style = findStyle(diagram, styleId);

	IGaService gaService = Graphiti.getGaService();
	if (style == null) { // style not found - create new style
		style = gaService.createStyle(diagram, styleId);
		style.setForeground(gaService.manageColor(diagram,
				GROUP_FOREGROUND));
		style.setBackground(gaService.manageColor(diagram,
				GROUP_BACKGROUND));
		style.setLineWidth(5);
		style.setLineStyle(LineStyle.DOT);
		style.setTransparency(0.8);
	}
	return style;
}

I set the style for a rectangle this way:

Rectangle rectangle = gaService.createRectangle(containerShape);
rectangle.setStyle(StyleUtil.getStyleForGroup(targetDiagram));

The Problem ist, only backgroundcolor and foreground color work, linewidth, linestyle and transparency are ignored...

if i set these properties directly to the rectangle, it works:

Rectangle rectangle = gaService.createRectangle(containerShape);
rectangle.setStyle(StyleUtil.getStyleForGroup(targetDiagram));
rectangle.setTransparency(0.8);
rectangle.setLineStyle(LineStyle.DOT);
rectangle.setLineWidth(5);

Any ideas?

One further question: Is it possible to make only the rectangle transparent and not its border too?

That happens because linewidth, linestyle and transparency have default
values defined that are automatically set for new graphic algorithms and let
the values defined at the style be ignored. Would need to reset the values
at the graphics algorithms (to null) to get the values from the style.

This is very confusing and actually we have just improved that behavior for
the Juno M2 version of Graphiti, see
https://bugs.eclipse.org/bugs/show_bug.cgi?id=352542

Sorry, I missed that one: that is not possible since transparency always
relates to the complete rectangle. A workaround would be to add a
non-transparent rectangle drawing the border and add a child rectangle (via
direct graphics algorithm nesting) that defines the transparent filling.

I try to set my own style as discussed in above thread at the rectangle level which works fine for me.

This works correctly when I do not have any update feature associated.But when I apply update feature for the rectangle, the style that I applied stops working.

I tried to reset the style after updation.But at this point it does not take the linewidth and linestyle I give.

Is it that the defined style style is overwritten while updating?

Hemlata,

I'm afraid I didn't understand what you actually do in your update feature.
What do you mean with reset the style? Can you provide some coding?

Hi Michael,

I have the following stuff in my Add feature:

 

  Rectangle roundedRectangle = gaService.createRectangle(containerShape);

    roundedRectangle.setLineStyle(null);
    roundedRectangle.setLineWidth(null);
    roundedRectangle.setStyle(null);

    Style varStyle = gaService.createStyle(diagram_, STYLE_ID);

        varStyle.setForeground(gaService
                .manageColor(diagram_, CLASS_FOREGROUND));
        varStyle.setBackground(gaService.manageColor(diagram_,
                CLASS_BACKGROUND_YELLOW));

        varStyle.setLineStyle(LineStyle.SOLID);
        varStyle.setLineWidth(2);
        varStyle.setLineVisible(true);

      roundedRectangle.setStyle(varStyle);

This works as expected when I do not have an update feature defined at all.When I add the update feature the above style applied does not work.In update feature I just update the texts in rectangle and nothing related to style.

Hemlata,

this looks good and I don't see an issue here...

Without debugging that it will not be possible to answer. Are both features
(add and update) correctly called?
