We would like to create our nodes, which appear to the user to be a unit, but consist of some text, with an image below and zero or more lines of text below that, as shown in the attached imagefile. The grey boxes show the conceptual make up of the node, which may or may not be visible to the user as actual boxes - ideally we would see at least the outer box. The lower text box, and the overall Node should grow as more text is added to it, but ideally only downwards, not getting wider.

I found you have both CompositeNode and ContainerNode but am not sure which would be best to use for this.

I tried an example with Container node but the empty text is not displayed below the image - as shown in the screenshot jpg. It should look like 'initial view'.

Which would be best to use to get this effect/functionality? Or is there another type of node you would recommend?

Thanks, that gives me exactly what I wanted.

It would be even better if I could set it 'transparent' so any background image set on the diagram would show through.

You could either remove the Shape component from the node's template, which would also hide the border, or set its Brush property to a transparent color:

// in OrgChartNode constructor
setFill(new SolidBrush(new Color(0, 0, 0, 0)));

After changing text you could calculate new height for the node by summing the heights returned by getDesiredSize() method of components (title + image + text) and assigning it back to node's Bounds.

TextComonent.getDesiredSize() did not consider width limits, returning size for non-wrapped single line of text; this build should fix it:

What malware-blocking tool are you using? Can you download the new jar from this link instead?
https://mindfusion.eu/jdiag.4.1.2.zip

As for help file, click the Unblock button if there's one in its Properties window shown from Windows Explorer's context menu / Properties command.

The www. domain maps to the same site, so you should be able to download from https://www.mindfusion.eu/_beta/jdiag.4.1.2.zip ?

We have released version 4.1.2 with getDesiredSize fix included, you should be able to download the trial.zip from our main site if it's specifically unblocked.

You will need to pass a Graphics instance with appropriate scale transform applied to let ImageComponent convert from pixels to diagram.MeasureUnit. Assuming your node type has same components as OrgChartNode example:

// in node class
public void resizeToFitText(Graphics2D g)
{
	Rectangle2D.Float r = this.getBounds();
	XDimension2D.Double availableSize = new XDimension2D.Double(r.width, r.height);

	XDimension2D.Double titleSize = title.getDesiredSize(availableSize, g);
	XDimension2D.Double imageSize = image.getDesiredSize(availableSize, g);
	XDimension2D.Double textSize = text.getDesiredSize(availableSize, g);

	float margin = 4;
	this.resize(r.width,
		(float) (titleSize.height + imageSize.height + textSize.height + margin));
}

// in frame class
public void nodeClicked(NodeEvent e)
{
	if (e.getNode() instanceof OrgChartNode)
	{
		Graphics2D g = (Graphics2D) diagramView.getGraphics();
		double unitScale = MeasureUnit.Millimeter.convert(1, MeasureUnit.Pixel, diagramView);
		g.scale(unitScale, unitScale);

		OrgChartNode orgNode = (OrgChartNode)e.getNode();
		orgNode.resizeToFitText(g);
	}
} 

I hope that helps,

The one from the first namespace, I have this import in my test node and the code above compiles fine:

import com.mindfusion.diagramming.XDimension2D;

That download only contained a fix for getDesiredSize to consider width constraints. It should not affect XDimension2D.Double visibility. Anyway the fix is now available in official release here, which you had access to earlier?

Ok, I've changed the Build Path settings in Eclipse to use external jar instead of project and it stopped compiling for me too.

Using the Change Type fix from error popup changes the declaration to XDimension2D$Double, which works, so I suppose the obfuscator we use cannot handle nested types correctly Since the type inherits from Dimension2D, you can avoid the ugly name when using fromRect instead of constructor:

Dimension2D d = XDimension2D.fromRect(rect);
//Dimension2D d = new XDimension2D$Double(...); 

I hope that helps,
