Default height issue with GWT canvas in SmartGWT Layout

[jgin]

I am trying to add a GWT canvas within a SmartGWT VLayout. It appears the SmartGWT/GWT canvas height defaults to a minimum of 100... no matter what I specify for the GWT canvas height.

What am I missing here?

Any help would be appreciated.

FYI, I am running SmartGWT v2.1 with GWT v2.0.3. The issue appears browser independent, as I have tried this on Safari and Firefox.

Here is an example of code:
[CODE]
VLayout layout = new VLayout();
layout.setWidth100();
layout.setHeight100();

gwt.canvas.client.Canvas gwtCanvas = new gwt.canvas.client.Canvas(300, 24);

layout.addMember(gwtCanvas);
[\CODE]

I had the exact same problem with SmartGWT and gwt-canvas. If you put your gwt canvas in a SmartGWT Layout and your gwt canvas was less than 100px high, no matter what you do, the Layout always defaults to a height of 100px. My workaround was to put the gwt canvas in a GWT SimplePanel and the SimplePanel into a SmartGWT VLayout and the problem disappears. I'm not sure why that makes a difference, but it does.

Here is what you can try:

VLayout layout = new VLayout();
layout.setWidth100();
layout.setHeight(1);
layout.setOverflow(Overflow.VISIBLE);
      
SimplePanel simple = new SimplePanel();
simple.setHeight("24px");
simple.setWidth("100%");
      
gwt.canvas.client.Canvas gwtCanvas = new gwt.canvas.client.Canvas(300, 24);
gwtCanvas.setStrokeStyle("#000000");
gwtCanvas.setLineWidth(2);
gwtCanvas.beginPath();
gwtCanvas.moveTo(30, 1);
gwtCanvas.lineTo(45, 20);
gwtCanvas.stroke();

simple.add(gwtCanvas);
      
layout.addMember(simple);

Hope this helps.
