Security Warning control interface. This class provides a couple of methods that help a developer relocate the AWT security warning to an appropriate position relative to the current window size. A "top-level window" is an instance of the Window class (or its descendant, such as JFrame). The security warning is applied to all windows created by an untrusted code. All such windows have a non-null "warning string" (see Window.getWarningString()). 

WARNING: This class is an implementation detail and only meant
for limited use outside of the core platform. This API may change
drastically between update release, and it may even be
removed or be moved to some other packages or classes.

Deprecated:This class is deprecated, no replacement.

Sets the position of the security warning.

 The alignmentX and alignmentY arguments specify the origin of the coordinate system used to calculate the position of the security warning. The values must be in the range [0.0f...1.0f]. The 0.0f value represents the left (top) edge of the rectangular bounds of the window. The 1.0f value represents the right (bottom) edge of the bounds. Whenever the size of the window changes, the origin of the coordinate system gets relocated accordingly. For convenience a developer may use the Component.*_ALIGNMENT constants to pass predefined values for these arguments. 
 The point argument specifies the location of the security warning in the coordinate system described above. If both x and y coordinates of the point are equal to zero, the warning will be located right in the origin of the coordinate system. On the other hand, if both alignmentX and alignmentY are equal to zero (i.e. the origin of the coordinate system is placed at the top-left corner of the window), then the point argument represents the absolute location of the security warning relative to the location of the window. The "absolute" in this case means that the position of the security warning is not effected by resizing of the window. 

Note that the security warning management code guarantees that:

    

  • The security warning cannot be located farther than two pixels from the rectangular bounds of the window (see Component.getBounds), and 
  • The security warning is always visible on the screen.


If either of the conditions is violated, the calculated position of the
security warning is adjusted by the system to meet both these
conditions.


The default position of the security warning is in the upper-right
corner of the window, two pixels to the right from the right edge. This
corresponds to the following arguments passed to this method:

    

  • alignmentX = Component.RIGHT_ALIGNMENT 
  • alignmentY = Component.TOP_ALIGNMENT 
  • point = (2, 0) 


Params:
  • window – the window to set the position of the security warning for
  • alignmentX – the horizontal origin of the coordinate system
  • alignmentY – the vertical origin of the coordinate system
  • point – the position of the security warning in the specified
coordinate system
Throws:
