NAME
       Tk::Wm::Popup - popup dialog windows.

SYNOPSIS
	$dialog->Popup(qw/
	    -popover	=> 'cursor' | $widget | undef,
	    -overanchor => c | n | ne | e | se | s | sw | w | nw,
	    -popanchor	=> c | n | ne | e | se | s | sw | w | nw,
	/);

DESCRIPTION
       You've probably had occasion to use a Dialog (or DialogBox) widget.
       These widgets are derived from a Toplevel (which is a subclass of
       Tk::Wm, the window manager) and spend most of their time in a withdrawn
       state. It's also common to use Toplevels as containers for custom built
       popup windows.  Menus, too, are dialogs derived from the window manager
       class. For this discussion, we'll use the simple term dialog to refer
       any widget that pops up and awaits user interaction, whether it be a
       Menu, a special purpose Toplevel, or any of the dialog-type widgets,
       including, but not limited to, ColorEditor, Dialog, DialogBox,
       ErrorDialog, FileSelect, FBox, getOpenFile and getSaveFile.

       When it's time to display these dialogs, we call the Perl/Tk window
       manager Popup method. Popup accepts three special purpose options that
       specify placement information in high-level terms rather than numerical
       coordinates. It is Popup's responsibility to take our human
       specifications and turn them into actual screen coordinates before
       displaying the dialog.

       We can direct the dialog to appear in two general locations, either
       over another window (e.g. the root window (screen) or a particular
       widget), or over the cursor. This is called the popover location. Once
       we've made this decision we can further refine the exact placement of
       the dialog relative to the popover location by specifying the
       intersection of two anchor points. The popanchor point is associated
       with the dialog and the overanchor point is associated with the popover
       location (whether it be a window or the cursor). The point where the
       two anchor points coincide is the popup locus. Anchor points are string
       values and can be c (for center), or any of the eight cardinal compass
       points: n, ne, e, se, s, sw, w or nw.

       For example, if -popover specifies a widget, -popanchor is sw, and
       -overanchor is ne, the the dialog's southwest corner pops up at the
       widget's northeast corner.

OPTIONS
       The options recognized by Popup are as follows:

       -popover
	   Specifies whether the dialog "pops over" a window or the cursor.
	   It may be the string cursor, a widget reference, or undef for the
	   root window.

       -popanchor
	   Specifies the anchor point of the dialog.  For instance, if e is
	   specified, the right side of the dialog is the anchor.

       -overanchor
	   Specifies where the dialog should anchor relative to the popover
	   location. For instance, if e is specified the dialog appears over
	   the right side of the popover location and if it's ne the the
	   dialog is positioned at the upper-right corner of the popover
	   location.
