documentation
"
    this class implements a pop-up box to show an information message. 
    WarningBoxes are basically InfoBoxes with a different bitmap-image.
    (also, they add a beep when popping up)

    They are created with:

	aBox := WarningBox title:'some title'.

    and shown with:

	aBox showAtPointer

    The default box shows 'yes' in its button; this can be changed with:

	aBox okText:'some string'.

    Since showing warnings is a common action, a convenient method has been
    added to Object; thus you can use:

	self warn:'oops - headcrash'

    everywhere in your code.

examples
"
    Examples:

	|aBox|

	aBox := WarningBox title:'Press ''OK'' to continue'.
	aBox okText:'OK'.
	aBox showAtPointer.

    since warnboxes are much like infoBoxes, all of look can be changed
    like described there:

	|aBox|

	aBox := WarningBox title:'Press ''OK'' to continue'.
	aBox okText:'yes, continue'.
	aBox form:(Image fromFile:'bitmaps/SmalltalkX.xbm').
	aBox showAtPointer.
