- Method Detail
  - getWidthInPixel
```
public double getWidthInPixel()
```
    Specified by:
    
    getWidthInPixel in interface AttributeReadSize
    
    Returns:
    
    the width of this object in pixels.
    NOTE: The result will typically be an int value. However, to be compatible with UiSize.getAmount() and with some underlying native toolkits we use double. You may cast the result to int.
  - getHeightInPixel
```
public double getHeightInPixel()
```
    Specified by:
    
    getHeightInPixel in interface AttributeReadSize
    
    Returns:
    
    the height of this object in pixels.
    NOTE: The result will typically be an int value. However, to be compatible with UiSize.getAmount() and with some underlying native toolkits we use double. You may cast the result to int.
  - getDpi
```
public double getDpi()
```
    Specified by:
    
    getDpi in interface UiScreen
    
    Returns:
    
    the dots per inch (DPI) rate of this display.
  - getSize
```
public double getSize()
```
    Specified by:
    
    getSize in interface UiScreen
    
    Returns:
    
    screen size (diagonal) in inches.
  - getType
```
public UiScreenType getType()
```
    Specified by:
    
    getType in interface UiScreen
    
    Returns:
    
    the UiScreenType that categorizes the display size.
  - update
```
public void update()
```
    Description copied from interface: UiScreen
    
    Forces the display to update. Typically the screen-resolution does not change while your application is running. Therefore values of UiScreen may be pre-calculated and cached. However, you can call this method before reading resolution or screen type to force that you are getting most recent values.
    
    Specified by:
    
    update in interface UiScreen
  - doUpdate
```
protected abstract void doUpdate()
```
    Called from update() to update the native values while update() will by default also update calculated values.
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
