NAME¶
Prima::Label - static text widget
DESCRIPTION¶
The class is designed for the display of text and provides no user interaction. The text output capabilities include wrapping, horizontal and vertical alignment, and automatic widget resizing to match text extensions. If the text contains a tilde-escaped ( hot ) character, the label can explicitly focus the specified widget upon pressing of the character key; this feature is useful for the design of dialogs.
Labels can display rich text with links. See Prima::Drawable::Markup for more.
SYNOPSIS¶
use Prima qw(Label InputLine Application); my $w = Prima::MainWindow->new; $w->insert( 'Prima::Label', text => 'Enter ~name:', focusLink => 'InputLine1', alignment => ta::Center, pack => { fill => 'x', side => 'top', pad => 10 }, ); $w->insert( 'Prima::InputLine', text => '', pack => { fill => 'x', side => 'top', pad => 10 }, ); run Prima;
API¶
Properties¶
- alignment INTEGER
- One of the following "ta::XXX"
constants:
ta::Left ta::Center ta::Right
Selects the horizontal text alignment.
Default value: "ta::Left"
- autoHeight BOOLEAN
- If 1, the widget height is automatically changed as text extensions
change.
Default value: 0
- autoWidth BOOLEAN
- If 1, the widget width is automatically changed as text extensions change.
Default value: 1
- focusLink WIDGET
- Points to a widget or a widget name (has to be a sibling widget), which is
explicitly focused when the user presses the combination of the hotkey
with the "Alt" key.
Prima::Label does not provide a separate property to access the hotkey value from the tilde-escaped string, however, it can be read from the "{accel}" variable.
Default value: "undef".
- hotKey CHAR
- A key (defined by CHAR) that the label will react to if pressed if the label has the focus The combination ALT + Key works always whether the label has the focus or not
- linkColor COLOR
- The color of text in links.
The default value is taken from Prima::Widget::Link and is currently hardcoded as green. So far there is no support for the system link color.
- showAccelChar BOOLEAN
- If 0, the tilde ( ~ ) character is collapsed from the text, and the hot
character is underlined. When the user presses the combination of the
escaped character with the "Alt" key,
the "focusLink" widget is explicitly
focused.
If 1, the text is shown as is, and no hot character is underlined. Key combinations with the "Alt" key are not recognized. See also: "hotKey".
Default value: 0
- showPartial BOOLEAN
- Used to determine if the last line of text should be drawn if it can not
be vertically fit in the widget interior. If 1, the last line is shown
even if not visible in full. If 0, only full lines are drawn.
Default value: 1
- textJustify $BOOL | { letter => 0, word => 0, kashida => 0, min_kashida => 0 } | %VALUES
- If set, justifies wrapped text according to the option passed in the hash
( see "arabic_justify" in Prima::Drawable::Glyphs and
"interspace_justify" in Prima::Drawable::Glyphs ). Can accept
three forms:
If an anonymous hash is used, overwrites all the currently defined options.
If $BOOL is used, treated as a shortcut for "{ letter => $BOOL, word => $BOOL, kashida => $BOOL }"; consequent get-calls return a full hash, not the $BOOL value.
If the %VALUES form is used, overwrites only values found in %VALUES.
Only actual when "wordWrap" is set.
- textDirection BOOLEAN
- If set, indicates RTL text direction.
- wordWrap BOOLEAN
- If 0, the text is not wrapped unless new line characters are present in
the text.
If 1, the text is wrapped if it can not be fit horizontally in the widget interior. The text is also wrapped over new lines.
Default value: 0
- valignment INTEGER
- One of the following "ta::XXX"
constants:
ta::Top ta::Middle or ta::Center ta::Bottom
Selects the vertical text alignment.
Note: the "ta::Middle" value is not equal to "ta::Center"'s, however, both constants produce an equal effect here.
Default value: "ta::Top"
