Gtk2::Ex::FormFactory::Label - A Label in a FormFactory framework

  Gtk2::Ex::FormFactory::Label->new (
    with_markup => Should the label render with markup?,
    bold        => Should the label render as bold text?,
    for         => Name for Widget this label belongs to,
    ...
    Gtk2::Ex::FormFactory::Widget attributes
  );

This class implements a Label in a Gtk2::Ex::FormFactory framework. The text of the Label is the value of the associated application object attribute. If no object is associated with the Label, the text is taken from the standard label attribute.

  Gtk2::Ex::FormFactory::Layout
  Gtk2::Ex::FormFactory::Rules
  Gtk2::Ex::FormFactory::Context
  Gtk2::Ex::FormFactory::Proxy

Attributes are handled through the common get_ATTR(), set_ATTR() style accessors, but they are mostly passed once to the object constructor and must not be altered after the associated FormFactory was built.

with_markup = BOOL [optional]

If this is set to TRUE the Label may contain basic HTML markup, which is rendered accordingly. Refer to the "Pango Text Attribute Markup" chapter in the Gtk+ documentation for details.

bold = BOOL [optional]

If set to TRUE the label is implicitly renderd as markup set into <b>...</b> tags.

for = SCALAR [optional]

If this label belongs to another widget pass the widget's name here. This way the label greys out automatically, if the widget gets inactive.

You may not just specify a simple name here but reference siblings of the label widget as well by specifying

  sibling($nr)

whereby $nr has a negative value to address siblings left from the Label and positive to address right siblings. E.g. sibling(-1) is the first left sibling and sibling(2) the second on the right.

If you add your Widgets to a Gtk2::Ex::ForFactory::Form container the label attributes of the Widgets are rendered automatically correspondently. But you need this feature for complex layouts not covered by Gtk2::Ex::ForFactory::Form, e.g. in a Gtk2::Ex::ForFactory::Table.

For more attributes refer to Gtk2::Ex::FormFactory::Widget.
