Img from DrawPane

[bc]

Hi,

I am trying to get an Img from my DrawPane but I am getting a blank image. Can you please tell me what I am doing wrong.

I am using SmartGwt 5.0p Pro. I tried this on IE 11 and ff.

import com.google.gwt.core.client.EntryPoint;
import com.smartgwt.client.widgets.Img;
import com.smartgwt.client.widgets.drawing.DrawPane;
import com.smartgwt.client.widgets.drawing.DrawRect;

public class DrawPaneTest implements EntryPoint {

	@Override
	public void onModuleLoad() {
		DrawPane dp = new DrawPane();
		dp.setWidth(100);
		dp.setHeight(100);
		dp.setTop(100);
		dp.setLeft(100);
		dp.setBorder("1px solid black");
		dp.draw();
		
		DrawRect dr = new DrawRect();
		dr.setWidth(30);
		dr.setHeight(30);
		dr.setTop(10);
		dr.setLeft(10);
		dr.setFillColor("red");
		dr.setDrawPane(dp);
		dr.draw();
		
		Img i = new Img();
		i.setID("myimg");
		i.setWidth(100);
		i.setHeight(100);
		i.setTop(100);
		i.setLeft(300);
		i.setSrc(dp.getDataURL());
		i.draw();
	}
}

The page source shows this for the Img

<div class="normal" id="isc_2" style="left: 300px; top: 100px; width: 100px; height: 100px; overflow: visible; position: absolute; z-index: 200036;" onscroll="return myimg.$lh()" eventproxy="myimg">
    <div id="isc_1" style="width: 100%; vertical-align: top; display: inline-block; visibility: inherit; position: relative; z-index: 200036; cursor: default; box-sizing: border-box;" eventproxy="myimg">
        <img name="isc_1main" width="100" height="100" align="TEXTTOP" draggable="true" src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAGIAAABiCAYAAACrpQYOAAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAA8SURBVHhe7cExAQAAAMKg9U9tCU8gAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAC5qlnIAAacfqhgAAAAASUVORK5CYII=" border="0" suppress="TRUE">
    </div>
</div>

Thanks.

This was a timing issue since draw operations are delayed so that they can be performed all at once. We've now made a call to getDataURL() automatically force all draw operations to complete, so this is fixed for tomorrow's nightly builds of 4.1 and up.

Thanks for the fix. Looks good now.
