:mod:`apt.progress.gtk2` --- Progress reporting for GTK+ interfaces
===================================================================
.. module:: apt.progress.gtk2
The :mod:`apt.progress.gtk2` module provides classes with GObject signals and
a class with a GTK+ widget for progress handling.
GObject progress classes
-------------------------
.. class:: GInstallProgress
An implementation of :class:`apt.progress.base.InstallProgress` supporting
GObject signals. The class emits the following signals:
.. describe:: status-changed(status: str, percent: int)
Emitted when the status of an operation changed.
.. describe:: status-started()
Emitted when the installation started.
.. describe:: status-finished()
Emitted when the installation finished.
.. describe:: status-timeout()
Emitted when a timeout happens
.. describe:: status-error()
Emitted in case of an error.
.. describe:: status-conffile()
Emitted when a conffile update is happening.
.. class:: GAcquireProgress
An implementation of :class:`apt.progress.base.AcquireProgress` supporting
GObject signals. The class emits the following signals:
.. describe:: status-changed(description: str, percent: int)
Emitted when the status of the fetcher changed, e.g. when the
percentage increased.
.. describe:: status-started()
Emitted when the fetcher starts to fetch.
.. describe:: status-finished()
Emitted when the fetcher finished.
.. class:: GDpkgInstallProgress
An implementation of :class:`apt.progress.base.InstallProgress` supporting
GObject signals. This is the same as :class:`GInstallProgress` and is thus
completely deprecated.
.. class:: GOpProgress
An implementation of :class:`apt.progress.old.FetchProgress` supporting
GObject signals. The class emits the following signals:
.. describe:: status-changed(operation: str, percent: int)
Emitted when the status of an operation changed.
.. describe:: status-started()
Emitted when it starts - Not implemented yet.
.. describe:: status-finished()
Emitted when all operations have finished.
GTK+ Widget
-----------
.. class:: GtkAptProgress
Graphical progress for installation/fetch/operations, providing
a progress bar, a terminal and a status bar for showing the progress
of package manipulation tasks.
.. method:: cancel_download()
Cancel a currently running download.
.. method:: clear()
Reset all status information.
.. attribute:: dpkg_install
Return the install progress handler for dpkg.
.. attribute:: fetch
Return the fetch progress handler.
.. method:: hide_terminal()
Hide the expander with the terminal widget.
.. attribute:: install
Return the install progress handler.
.. attribute:: open
Return the cache opening progress handler.
.. method:: show()
Show the Box
.. method:: show_terminal(expanded=False)
Show an expander with a terminal widget which provides a way to
interact with dpkg.
Example
-------
.. literalinclude:: ../examples/apt-gtk.py
