6 Prima::MsgBox - standard message and input dialog boxes
7
9 The module contains two methods, "message_box" and "input_box", that
10 invoke correspondingly the standard message and one line text input
11 dialog boxes.
12
14 use Prima;
15 use Prima::Application;
16 use Prima::MsgBox;
17 my $text = Prima::MsgBox::input_box( 'Sample input box', 'Enter text:', '');
19 $text = '(none)' unless defined $text;
20 Prima::MsgBox::message( "You have entered: '$text'", mb::Ok);
21
23 input_box TITLE, LABEL, INPUT_STRING, [ BUTTONS = mb::OkCancel,
24 %PROFILES ]
25 Invokes standard dialog box, that contains an input line, a text
26 label, and buttons used for ending dialog session. The dialog box
27 uses TITLE string to display as the window title, LABEL text to
28 draw next to the input line, and INPUT_STRING, which is the text
29 present in the input box. Depending on the value of BUTTONS integer
30 parameter, which can be a combination of the button "mb::XXX"
31 constants, different combinations of push buttons can be displayed
32 in the dialog.
33 PROFILE parameter is a hash, that contains customization parameters
35 for the buttons and the input line. To access input line
36 "inputLine" hash key is used. See "Buttons and profiles" for more
37 information on BUTTONS and PROFILES.
38 Returns different results depending on the caller context. In
40 array context, returns two values: the result of
41 "Prima::Dialog::execute", which is either "mb::Cancel" or one of
42 "mb::XXX" constants of the dialog buttons; and the text entered.
43 The input text is not restored to its original value if the dialog
44 was cancelled. In scalar context returns the text entered, if the
45 dialog was ended with "mb::OK" or "mb::Yes" result, or "undef"
46 otherwise.
47 message TEXT, [ OPTIONS = mb::Ok | mb::Error, %PROFILES ]
49 Same as "message_box" call, with application name passed as the
50 title string.
51 message_box TITLE, TEXT, [ OPTIONS = mb::Ok | mb::Error, %PROFILES ]
53 Invokes standard dialog box, that contains a text label, a
54 predefined icon, and buttons used for ending dialog session. The
55 dialog box uses TITLE string to display as the window title, TEXT
56 to display as a main message. Value of OPTIONS integer parameter is
57 combined from two different sets of "mb::XXX" constants. The first
58 set is the buttons constants, - "mb::OK", "mb::Yes" etc. See
59 "Buttons and profiles" for the explanations. The second set
60 consists of the following message type constants:
61 mb::Error
63 mb::Warning
64 mb::Information
65 mb::Question
66 While there can be several constants of the first set, only one
68 constant from the second set can be selected. Depending on the
69 message type constant, one of the predefined icons is displayed and
70 one of the system sounds is played; if no message type constant is
71 selected, no icon is displayed and no sound is emitted. In case if
72 no sound is desired, a special constant "mb::NoSound" can be used.
73 PROFILE parameter is a hash, that contains customization parameters
75 for the buttons. See "Buttons and profiles" for the explanations.
76 Returns the result of "Prima::Dialog::execute", which is either
78 "mb::Cancel" or one of "mb::XXX" constants of the specified dialog
79 buttons.
80 Buttons and profiles
82 The message and input boxes provide several predefined buttons that
83 correspond to the following "mb::XXX" constants:
84 mb::OK
86 mb::Cancel
87 mb::Yes
88 mb::No
89 mb::Abort
90 mb::Retry
91 mb::Ignore
92 mb::Help
93 To provide more flexibility, PROFILES hash parameter can be used. In
95 this hash, predefined keys can be used to tell the dialog methods about
96 certain customizations:
97 defButton INTEGER
99 Selects the default button in the dialog, i.e. the button that
100 reacts on the return key. Its value must be equal to the "mb::"
101 constant of the desired button. If this option is not set, the
102 leftmost button is selected as the default.
103 helpTopic TOPIC
105 Used to select the help TOPIC, invoked in the help viewer window if
106 "mb::Help" button is pressed by the user. If this option is not
107 set, Prima is displayed.
108 inputLine HASH
110 Only for "input_box".
111 Contains a profile hash, passed to the input line as creation
113 parameters.
114 buttons HASH
116 To modify a button, an integer key with the corresponding "mb::XXX"
117 constant can be set with the hash reference under "buttons" key.
118 The hash is a profile, passed to the button as creation parameters.
119 For example, to change the text and behavior of a button, the
120 following construct can be used:
121 Prima::MsgBox::message( 'Hello', mb::OkCancel,
123 buttons => {
124 mb::Ok, {
125 text => '~Hello',
126 onClick => sub { Prima::message('Hello indeed!'); }
127 }
128 }
129 );
130 If it is not desired that the dialog must be closed when the user
132 presses a button, its "::modalResult" property ( see Prima::Buttons
133 ) must be reset to 0.
134 owner WINDOW
136 If set, the dialog owner is set to WINDOW, otherwise to
137 $::main_window. Necessary to maintain window stack order under
138 some window managers, to disallow windows to be brought over the
139 message box.
