Smart GWT and OpenLayers

[dead_passive]

Hi,

In my project I'm using Smart GWT and GWT OpenLayers (http://gwt-openlayers.sourceforge.net/). GWT OpenLayers has a GWT widget called MapWidget which contains a map.

I'm trying to put my map into a VLayout and have it fill up all available space. However, when I run my application the MapWidget always has a height of 0px. The code I'm using to add my MapWidget is as follows:

VLayout mapLayout = new VLayout();
mapLayout.setWidth100();
mapLayout.setHeight100();
mapLayout.setBackgroundColor("#FFFF99");

mapWidget = createMap();
mapLayout.addMember(mapWidget);

When I create my MapWidget, I try to make its size 100% by calling the widgets setWidth and setHeight methods. This all happens in createMap(). When I use the same createMap() method in a pure GWT application it works fine, so I don't think there's an issue there. I'm pretty sure the problem is with Smart GWT.

Has anybody has a similar problem before? Does anybody know how I might solve this?

Thanks!

Yes. I'm can not find normal solution for this problem. But hot fixs is create wrapped layout with size 100%.

Thanks for the reply. What do you mean by "create wrapped layout with size 100%"? I'm already putting my MapWidget inside a VLayout.

You can do something like:

MapWidget mapWidget = ...;
VLayout mapCanvas;
public void init(){
	mapCanvas = new VLayout ();
	mapCanvas.setWidth100();
	mapCanvas.setHeight100();

	mapCanvas.addResizedHandler(new ResizedHandler() {
		@Override
		public void onResized(ResizedEvent event) {
			resizeMapWidget();
		}
	});
	mapCanvas.addChild(mapWidget);
}

public void resizeMapWidget(){
	mapWidget.setHeight(String.valueOf(mapCanvas.getHeight())+"px");
	mapWidget.setWidth(String.valueOf(mapCanvas.getWidth())+"px");		
}

Do you have problems with automatic (no configuration) events managed by openlayers as pan, zoom, rectangle zoom?

Hi,
I'm facing quite the same problem:
Opening a SmartGWT modal window within an openlayers mapping application works ok - but after closing that window, navigation in the mapping application is not possible anymore.
Does anyone know how to give back control (event handling) back to the calling application??

Thanks a lot, this works fine!

You can do something like:

MapWidget mapWidget = ...;
VLayout mapCanvas;
public void init(){
	mapCanvas = new VLayout ();
	mapCanvas.setWidth100();
	mapCanvas.setHeight100();

	mapCanvas.addResizedHandler(new ResizedHandler() {
		@Override
		public void onResized(ResizedEvent event) {
			resizeMapWidget();
		}
	});
	mapCanvas.addChild(mapWidget);
}

public void resizeMapWidget(){
	mapWidget.setHeight(String.valueOf(mapCanvas.getHeight())+"px");
	mapWidget.setWidth(String.valueOf(mapCanvas.getWidth())+"px");		
}
