```
public static void resizeBy(int width,
                            int height)
```
    Resizes the window by the specified width and height. This method moves the bottom right corner of the window by the specified number of pixels defined. The top left corner will not be moved (it stays in its original coordinates).
    NOTE: In most modern browsers, this method only works with windows created by Window.open() with a supplied width and height.
    
    Parameters:
    
    width - A positive or a negative number that specifies how many pixels to resize the width by
    
    height - A positive or a negative number that specifies how many pixels to resize the height by
  - resizeTo
```
public static void resizeTo(int width,
                            int height)
```
    Resizes the window to the specified width and height.
    NOTE: In most modern browsers, this method only works with windows created by Window.open() with a supplied width and height.
    
    Parameters:
    
    width - The width of the window, in pixels
    
    height - The height of the window, in pixels
  - scrollTo
```
public static void scrollTo(int left,
                            int top)
```
    Scroll the window to the specified position.
    
    Parameters:
    
    left - the left scroll position
    
    top - the top scroll position
  - setMargin
```
public static void setMargin(String size)
```
    Sets the size of the margins used within the window's client area. It is sometimes necessary to do this because some browsers, such as Internet Explorer, add margins by default, which can confound attempts to resize panels to fit exactly within the window.
    
    Parameters:
    
    size - the window's new margin size, in CSS units.
  - setStatus
```
public static void setStatus(String status)
```
    Sets the status text for the window, if permitted by the browser's settings.
    
    Parameters:
    
    status - the new message to display.
  - setTitle
```
public static void setTitle(String title)
```
    Sets the browser window's title.
    
    Parameters:
    
    title - the new window title.
