SYNOPSIS

14           use Curses::UI;
15           my $cui = new Curses::UI;
16           my $win = $cui->add('window_id', 'Window');

18           my $label = $win->add(
19               'mylabel', 'Label',
20               -text      => 'Hello, world!',
21               -bold      => 1,

DESCRIPTION

27       Curses::UI::Label is a widget that shows a textstring.  This textstring
28       can be drawn using these special features: bold, dimmed, reverse,
29       underlined, and blinking.
30
31       See exampes/demo-Curses::UI::Label in the distribution for a short
32       demo.

STANDARD OPTIONS

35       -parent, -x, -y, -width, -height, -pad, -padleft, -padright, -padtop,
36       -padbottom, -ipad, -ipadleft, -ipadright, -ipadtop, -ipadbottom,
37       -title, -titlefullwidth, -titlereverse, -onfocus, -onblur

39       For an explanation of these standard options, see Curses::UI::Widget.

WIDGET-SPECIFIC OPTIONS

42       ·   -height < VALUE >
43
44           If you do not define -height, the label will compute its needed
45           height using the initial -text.
46
47       ·   -text < TEXT >
48
49           This will set the text on the label to TEXT.
50
51       ·   -textalignment < VALUE >
52
53           This option controls how the text should be aligned inside the
54           label. VALUE can be 'left', 'middle' and 'right'. The default value
55           for this option is 'left'.
56
57       ·   -paddingspaces < BOOLEAN >
58
59           This option controls if padding spaces should be added to the text
60           if the text does not fill the complete width of the widget. The
61           default value for BOOLEAN is false.  An example use of this option
62           is:
63
64               $win->add(
65                   'label', 'Label',
66                   -width         => -1,
67                   -paddingspaces => 1,
68                   -text          => 'A bit of text',
69               );
70
71           This will create a label that fills the complete width of your
72           screen and which will be completely in reverse font (also the part
73           that has no text on it). See the demo in the distribution
74           (examples/demo-Curses::UI::Label) for a clear example of this)
75
76       ·   -bold < BOOLEAN >
77
78           If BOOLEAN is true, text on the label will be drawn in a bold font.
79
80       ·   -dim < BOOLEAN >
81
82           If BOOLEAN is true, text on the label will be drawn in a dim font.
83
84       ·   -reverse < BOOLEAN >
85
86           If BOOLEAN is true, text on the label will be drawn in a reverse
87           font.
88
89       ·   -underline < BOOLEAN >
90
91           If BOOLEAN is true, text on the label will be drawn in an
92           underlined font.
93
94       ·   -blink < BOOLEAN >
95
96           If BOOLEAN is option is true, text on the label will be drawn in a
97           blinking font.

METHODS

100       ·   new ( OPTIONS )
101
102       ·   layout ( )
103
104       ·   draw ( BOOLEAN )
105
106       ·   intellidraw ( )
107
108       ·   focus ( )
109
110       ·   onFocus ( CODEREF )
111
112       ·   onBlur ( CODEREF )
113
114           These are standard methods. See Curses::UI::Widget for an
115           explanation of these.
116
117       ·   bold ( BOOLEAN )
118
119       ·   dim ( BOOLEAN )
120
121       ·   reverse ( BOOLEAN )
122
123       ·   underline ( BOOLEAN )
124
125       ·   blink ( BOOLEAN )
126
127           These methods can be used to control the font in which the text on
128           the label is drawn, after creating the widget. The font option will
129           be turned on for a true value of BOOLEAN.
130
131       ·   textalignment ( VALUE )
132
133           Set the textalignment. VALUE can be 'left', 'middle' or 'right'.
134
135       ·   text ( [TEXT] )
136
137           Without the TEXT argument, this method will return the current text
138           of the widget. With a TEXT argument, the text on the widget will be
139           set to TEXT.
140
141       ·   get ( )
142
143           This will call the text method without any argument and thus it
144           will return the current text of the label.
145

DEFAULT BINDINGS

147       Since a Label is a non-interacting widget, it does not have any
148       bindings.
