Hello Smart folk,

http://forums.smartclient.com/showthread.php?t=16084
http://stackoverflow.com/questions/4186082/smartgwt-make-window-background-transparent-no-color

but no one of them works for me, also I tried to make a sample application separated from my application the issue still appear in IE but on FF and Chrome works fine

I set Background Image and edge_Center Image which is transparent image and it work on firefox and Chrome but IE not give transparency for the background it seems it take white color.

also I tried to set background color to transparent but it still the same issue on IE.

Here is the sample application that I did:

Entry point class

	public void onModuleLoad() {

		Layout hh=new Layout();
		hh.setSize("100%", "100%");
		hh.setBackgroundColor("#00FF00");
		
		
		Button testButton = new Button("Test");
		testButton.setLeft(100);
		testButton.setTop(100);
		testButton.setWidth(50);
		testButton.setHeight(50);
		
		Window window=new Window();
		window.setSize("150", "150");
		window.setBackgroundColor("transparent");
		
		window.setEdgeImage("/HoverEdge/edge.png");
		window.setEdgeShowCenter(true);
		window.setEdgeCenterBackgroundColor("transparent");
		window.setBodyStyle("m-windowBody");
		window.setHeaderStyle("m-windowHeader");
		window.setStyleName("transperante-Window");
		window.setShowHeader(false);
		
		hh.addChild(testButton);
		window.show();
		hh.draw();
		
	}

CSS File

.m-windowHeader,
.m-dialogHeader {
 	
	background-color:transparent;
	
}
.transperante-Window{
	background: transparent;
}
.m-windowBody,
.m-dialogBody {
    background-color:transparent;
    background: transparent;
    
}

Note: please see the picture in the attachment that demonstrate the difference between running application on IE and running application on FF.
