fit the content to WebView in JavaFx

Question

I have a problem in getting the size of the content of a web view..here is my code

 String heightText = (String) engine.executeScript("window.getComputedStyle(document.body,null).getPropertyValue('height')");
    double height = Double.valueOf(heightText.replace("px", ""));
    String widthText = web1.getEngine().executeScript(
            "window.getComputedStyle(document.body,null).getPropertyValue('width')"
    ).toString();
    double width = Double.valueOf(widthText.replace("px", ""));
    web1.setPrefHeight(height);
    web1.setPrefWidth(width);
    System.out.println(height + "  " + width);


}

but it refers 0 at first time and in the other times it has wrong result.

actually I had to edit my question. the above code shows the size of the previous content.. why is it like this? please help. thank you

Please specify the proper version of Java FX that you're working with. — Luiggi Mendoza, Jul 13 '15 at 19:12

Make sure this code is called after Stage.show() or code displaying corresponding window. All height and width getters returns zero before UI initialisation.

Ensure that you wait until the document has loaded before retrieving document properties. Use a change listener on the state property of a load worker as outlined in the WebEngine javadoc.

Disclaimer: I haven't tried to do this for a long time, so the technique may or may not work with current and later JavaFX versions.

If you want to generate a layout pass for the scene graph, use the applyCss/layout functions, otherwise modifying the prefWidth of something, then getting the set width will not probably not match-up.
