Resize the screen in GWT

I am developing a GWT Web application and I would like to include the resize capability into the container. For that, I am implementing a combination of Vertical and Horizontal Panels within a FlowPanel which is resizable. Well, the code for the resize method is the following:

Window.addResizeHandler(new ResizeHandler() {
    @Override
    public void onResize(ResizeEvent event) {   
        flowPanel.setHeight(event.getHeight()+"px"); 
        flowPanel.setWidth(event.getWidth()+"px");
    }
});

However, when I change the size of the windows, the size of the web elements does not change. Do you know how to implement it?

Thank you very much in advance!!!

You may want to review your layout solution. There are very few cases when you need to use a ResizeHandler. Typically, you can achieve a desired layout either by using a LayoutPanel (or Horizontal/Vertical panels) that automatically resize with the window, or by using CSS. Then your layout will respond well to any changes in a browser window, and you don't need to write any code for that to happen.

EDIT:

In order for a widget to resize automatically, the parent widget must implement ProvidesResize, and the child widget must implement Resizable. FlowPanel does not implement either. Once you use it, the chain of resizing events is broken.

Typically, I use a LayoutPanel for my outmost container. It occupies the entire browser window when added to the RootPanel, and it adjusts with the Window. Vertical and Horizontal panels are similar.

use,

window.getClientWidth();
window.getClientHeight();

Based on your component size you can -/+ px and use.
