glade-0.11.1: Binding to the glade library.




Libglade facilitates loading of XML specifications of whole widget trees that have been interactively designed with the GUI builder Glade. The present module exports operations for manipulating GladeXML objects.

  • This binding does not support Libglade functionality that is exclusively meant for extending Libglade with new widgets. Like new widgets, such functionality is currently expected to be implemented in C.


Data types

Creation operations

xmlNew :: FilePath -> IO (Maybe GladeXML)Source

Create a new XML object (and the corresponding widgets) from the given XML file.

This corresponds to xmlNewWithRootAndDomain, but without the ability to specify a root widget or translation domain.



:: FilePath

the XML file name.

-> Maybe String

root - the widget node in fname to start building from (or Nothing)

-> Maybe String

domain - the translation domain for the XML file (or Nothing for default)

-> IO (Maybe GladeXML) 

Create a new GladeXML object (and the corresponding widgets) from the given XML file.

Optionally it will only build the interface from the widget node root (if it is not Nothing). This feature is useful if you only want to build say a toolbar or menu from the XML file, but not the window it is embedded in.

Note also that the XML parse tree is cached to speed up creating another GladeXML object for the same file.

Obtaining widget handles



:: WidgetClass widget 
=> GladeXML 
-> (GObject -> widget)

a dynamic cast function that returns the type of object that you expect, eg castToButton

-> String

the second parameter is the ID of the widget in the glade xml file, eg "button1".

-> IO widget 

Get the widget that has the given name in the interface description. If the named widget cannot be found or is of the wrong type the result is an error.

xmlGetWidgetRaw :: GladeXML -> String -> IO (Maybe Widget)Source

Like xmlGetWidget but it does not do any casting and if the named widget is not found then the result is Nothing rather than an error.
