NAME
Curses::UI::Label - Create and manipulate label widgets
CLASS HIERARCHY
Curses::UI::Widget
|
+----Curses::UI::Label
SYNOPSIS
use Curses::UI;
my $cui = new Curses::UI;
my $win = $cui->add('window_id', 'Window');
my $label = $win->add(
'mylabel', 'Label',
-text => 'Hello, world!',
-bold => 1,
);
$label->draw;
DESCRIPTION
Curses::UI::Label is a widget that shows a textstring. This textstring can be drawn using
these special features: bold, dimmed, reverse, underlined, and blinking.
See exampes/demo-Curses::UI::Label in the distribution for a short demo.
STANDARD OPTIONS
-parent, -x, -y, -width, -height, -pad, -padleft, -padright, -padtop, -padbottom, -ipad,
-ipadleft, -ipadright, -ipadtop, -ipadbottom, -title, -titlefullwidth, -titlereverse,
-onfocus, -onblur
For an explanation of these standard options, see Curses::UI::Widget.
WIDGET-SPECIFIC OPTIONS
o -height < VALUE >
If you do not define -height, the label will compute its needed height using the
initial -text.
o -text < TEXT >
This will set the text on the label to TEXT.
o -textalignment < VALUE >
This option controls how the text should be aligned inside the label. VALUE can be
'left', 'middle' and 'right'. The default value for this option is 'left'.
o -paddingspaces < BOOLEAN >
This option controls if padding spaces should be added to the text if the text does
not fill the complete width of the widget. The default value for BOOLEAN is false. An
example use of this option is:
$win->add(
'label', 'Label',
-width => -1,
-paddingspaces => 1,
-text => 'A bit of text',
);
This will create a label that fills the complete width of your screen and which will
be completely in reverse font (also the part that has no text on it). See the demo in
the distribution (examples/demo-Curses::UI::Label) for a clear example of this)
o -bold < BOOLEAN >
If BOOLEAN is true, text on the label will be drawn in a bold font.
o -dim < BOOLEAN >
If BOOLEAN is true, text on the label will be drawn in a dim font.
o -reverse < BOOLEAN >
If BOOLEAN is true, text on the label will be drawn in a reverse font.
o -underline < BOOLEAN >
If BOOLEAN is true, text on the label will be drawn in an underlined font.
o -blink < BOOLEAN >
If BOOLEAN is option is true, text on the label will be drawn in a blinking font.
METHODS

o reverse ( BOOLEAN )
o underline ( BOOLEAN )
o blink ( BOOLEAN )
These methods can be used to control the font in which the text on the label is drawn,
after creating the widget. The font option will be turned on for a true value of
BOOLEAN.
o textalignment ( VALUE )
Set the textalignment. VALUE can be 'left', 'middle' or 'right'.

Without the TEXT argument, this method will return the current text of the widget.
With a TEXT argument, the text on the widget will be set to TEXT.
o get ( )
This will call the text method without any argument and thus it will return the
current text of the label.
DEFAULT BINDINGS
Since a Label is a non-interacting widget, it does not have any bindings.
