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       Tk::Wm, the window manager) and spend most of their time in a withdrawn state.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.

NAME

       Tk::Dialog - Create modal dialog and wait for a response.

SYNOPSIS

	   $dialog = $parent->Dialog(-option => value, ... );

DESCRIPTION

       This procedure is part of the Tk script library - its arguments describe a dialog box.  After creating a dialog box, Dialog waits for the
       user to select one of the Buttons either by clicking on the Button with the mouse or by typing return to invoke the default Button (if
       any).  Then it returns the text string of the selected Button.

       While waiting for the user to respond, Dialog sets a local grab.  This prevents the user from interacting with the application in any way
       except to invoke the dialog box.  See the Show() method.

OPTIONS

       The following option/value pairs are supported:

       -title
	   Text to appear in the window manager's title bar for the dialog.

       -text
	   Message to appear in the top portion of the Dialog.

       -bitmap
	   If non-empty, specifies a bitmap to display in the top portion of the Dialog, to the left of the text.  If this is an empty string then
	   no bitmap is displayed in the Dialog.

       -default_button
	   Text label string of the Button that displays the default ring.

       -buttons
	   A reference to a list of Button label strings.  Each string specifies text to display in a Button, in order from left to right.

METHODS

       $answer = $dialog->Show(?-global?);
	   This method displays the Dialog, waits for the user's response, and stores the text string of the selected Button in $answer.  If
	   -global is specified a global (rather than local) grab is performed.

	   The actual Dialog is shown using the Popup method. Any other options supplied to Show are passed to Popup, and can be used to position
	   the Dialog on the screen. Please read Tk::Popup for details.

ADVERTISED WIDGETS

       Because Tk::Dialog is a subclass of Tk::DialogBox it inherits all the advertised subwidgets of its superclass: e.g. "B_button-text", where
       'button-text' is a Button's -text value. Additionally, Tk::Dialog advertises:

       message
	   The dialog's Label widget containing the message text.

       bitmap
	   The dialog's Label widget containing the bitmap image.

EXAMPLE

       $dialog = $mw->Dialog(-text => 'Save File?', -bitmap => 'question', -title => 'Save File Dialog', -default_button => 'Yes', -buttons =>
       [qw/Yes No Cancel/);
