```
public final class AppSettings
extends java.util.HashMap<java.lang.String,java.lang.Object>
```
AppSettings provides a store of configuration to be used by the application.
By default only the context uses the configuration, however the user may set and retrieve the settings as well. The settings can be stored either in the Java preferences (using save(java.lang.String)) or a .properties file (using save(java.io.OutputStream)).

public void setDepthBits(int value)
```
    Sets the number of depth bits to use.
    The number of depth bits specifies the precision of the depth buffer. To increase precision, specify 32 bits. To decrease precision, specify 16 bits. On some platforms 24 bits might not be supported, in that case, specify 16 bits.
    (Default: 24)
    
    Parameters:
    
    value - The depth bits
  - setAlphaBits
```
public void setAlphaBits(int value)
```
    Android Only Sets the number of alpha bits to use.
    The number of alpha bits specifies the precision of the surface view background alpha value. To set the surface view to opaque (fastest setting), leave the number of alpha bits = 0. This will cause faster rendering, but android views located behind the surface view will not be viewable. To set the surface view to translucent, set the number of alphaBits to 8 or higher. Values less than 8 (except 0) will set the surface view pixel format to transparent.
    (Default: 0)
    
    Parameters:
    
    value - The alpha bits
  - setStencilBits
```
public void setStencilBits(int value)

    Set the number of stencil bits.
    This value is only relevant when the stencil buffer is being used. Specify 8 to indicate an 8-bit stencil buffer, specify 0 to disable the stencil buffer.
    (Default: 0)

    value - The bits per pixel to set (Default: 24)
  - setSamples
```
public void setSamples(int value)
```
    Set the number of samples per pixel. A value of 1 indicates each pixel should be single-sampled, higher values indicate a pixel should be multi-sampled.
    
    Parameters:
    
    value - The number of samples (Default: 1)
  - setTitle
```
public void setTitle(java.lang.String title)

public void setStereo3D(boolean value)
```

    Once enabled, filters or scene processors that handle 3D stereo rendering could use this feature to render using hardware 3D stereo.
    
    Parameters:
    
    value - true to enable 3-D stereo, false to disable (default=false)
  - setIcons
```
public void setIcons(java.lang.Object[] value)
```
    Sets the application icons to be used, with the most preferred first. For Windows, you should supply at least one 16x16 icon and one 32x32. The former is used for the title/task bar, the latter for the alt-tab icon. Linux (and similar platforms) expect one 32x32 icon. Mac OS X should be supplied one 128x128 icon.
    The icon is used for the settings window, and the LWJGL render window. Note that a bug in Java 6 (bug ID 6445278, currently hidden but available in Google cache) currently prevents the icon working for alt-tab on the settings dialog in Windows.
    
    Parameters:
    
    value - An array of BufferedImages to use as icons. (Default: not set)
  - setSettingsDialogImage
```
