NAME

6       Tk::Dialog - Create modal dialog and wait for a response.
7

SYNOPSIS

9           $dialog = $parent->Dialog(-option => value, ... );
10

DESCRIPTION

12       This procedure is part of the Tk script library - its arguments
13       describe a dialog box.  After creating a dialog box, Dialog waits for
14       the user to select one of the Buttons either by clicking on the Button
15       with the mouse or by typing return to invoke the default Button (if
16       any).  Then it returns the text string of the selected Button.
17
18       While waiting for the user to respond, Dialog sets a local grab.  This
19       prevents the user from interacting with the application in any way
20       except to invoke the dialog box.  See the Show() method.
21

OPTIONS

23       The following option/value pairs are supported:
24
25       -title
26           Text to appear in the window manager's title bar for the dialog.
27
28       -text
29           Message to appear in the top portion of the Dialog.
30
31       -bitmap
32           If non-empty, specifies a bitmap to display in the top portion of
33           the Dialog, to the left of the text.  If this is an empty string
34           then no bitmap is displayed in the Dialog.
35
36       -default_button
37           Text label string of the Button that displays the default ring.
38
39       -buttons
40           A reference to a list of Button label strings.  Each string
41           specifies text to display in a Button, in order from left to right.
42

METHODS

44       $answer = $dialog->Show(?-global?);
45           This method displays the Dialog, waits for the user's response, and
46           stores the text string of the selected Button in $answer.  If
47           -global is specified a global (rather than local) grab is
48           performed.
49
50           The actual Dialog is shown using the Popup method. Any other
51           options supplied to Show are passed to Popup, and can be used to
52           position the Dialog on the screen. Please read Tk::Popup for
53           details.

ADVERTISED WIDGETS

56       Because Tk::Dialog is a subclass of Tk::DialogBox it inherits all the
57       advertised subwidgets of its superclass: e.g. "B_button-text", where
58       'button-text' is a Button's -text value. Additionally, Tk::Dialog
59       advertises:
60
61       message
62           The dialog's Label widget containing the message text.
63
64       bitmap
65           The dialog's Label widget containing the bitmap image.
66

EXAMPLE

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