Pympress package

This page contains the inline documentation, generated from the code using sphinx.

The code is documented in the source using the Google style for docstrings. Sphinx has gathered a set of examples which serves as a better crash course than the full style reference.

Retructured text (rst) can be used inside the comments and docstrings.

Modules

pympress.util.get_pympress_meta()[source]

Get metadata (version, etc) from pympress’ __init__.py or git describe.

Returns:: metadata properties (version, contributors) mapped to their values
Return type:: dict

pympress.util.close_opened_resources()[source]: Close all importlib context managers for resources that we needed over the program lifetime.

pympress.util.get_translation(domain)[source]

Returns a gettext translation object.

This re-implements gettext’s translation() and find() to allow using a python 3.9 Traversable as localedir

Returns:: A gettext translation object with the strings for the domain loaded
Return type:: NullTranslations

pympress.util.get_portable_config()[source]

Returns the path to the configuration file for a portable install (i.e. in the install root).

May return None if the install root is not a real directory (e.g. in a zip file).

Returns:: The path to the portable configuration file.
Return type:: Path or None

pympress.util.get_default_config()[source]

Returns the path to the configuration file containing the defaults.

Returns:: The path to the portable configuration file.
Return type:: Path

pympress.util.get_user_config()[source]

Returns the path to the configuration file in the user config directory

Returns:: path to the user configuration file.
Return type:: Path

pympress.util.load_style_provider(style_provider)[source]

Load the css and in a style provider

Parameters:: style_provider (CssProvider) – The style provider in which to load CSS
Returns:: The style provider with CSS loaded
Return type:: CssProvider

pympress.util.get_icon_path(name)[source]

Get the path for an image from pympress’ resources

Parameters:: name (str) – The name of the icon to load
Returns:: The path to the icon to load
Return type:: str

pympress.util.get_ui_resource_file(name, ext='.glade')[source]

Load an UI definition file from pympress’ resources

Parameters:

name (str) – The name of the UI to load
ext (str) – The extension of the file

Returns:

The full path to the glade file

Return type:

str

pympress.util.list_icons()[source]

List the icons from pympress’ resources.

Returns:: The paths to the icons in the pixmaps directory
Return type:: list of str

pympress.util.get_log_path()[source]

Returns the appropriate path to the log file in the user app dirs.

Returns:: path to the log file.
Return type:: Path

pympress.util.fileopen(f)[source]

Call the right function to open files, based on the platform.

Parameters:: f (path-like) – path to the file to open

pympress.util.introspect_flag_value(flags_class, nick, fallback)[source]

Get the value of a flag from its class, given a value’s name (or nick)

Introspection technique (in particular __flags_values__ dict) inspired from pygtkcompat. This is needed because there is no typelib for libgstplayback.

Parameters:

flags_class (a type inheriting from GFlags) – the flags class to introspect
nick (str) – a name or nick of the flag value that should be returned
fallback (int) – the documented flag value, if lookup fails

pympress.util.hard_set_screensaver(disabled)[source]

Enable or disable the screensaver.

Parameters:: disabled (bool) – if True, indicates that the screensaver must be disabled; otherwise it will be enabled

exception pympress.util.NoMonitorPositions[source]

Bases: Exception

The Exception we raise when there is no way of figuring out the monitor position of windows

class pympress.util.ScreenArea(obj)[source]

Bases: object

Convenience class to represent monitors or windows in terms of the area (position and size) they use on screen

This is similar to Monitor, but necessary as we want to handle “mirrored” monitors as if they were a single monitor, and only use “extended” monitors as target for content window position and/or fullscreening.

most_intersection(candidates)[source]

Find the rectangle that intersects most with rect in candidates

Parameters:: candidates (iterable of `ScreenArea`s) – The monitor areas to check for intersection
Returns:: The best candidate screen area, i.e. that has the largest intersection
Return type:: ScreenArea

least_intersection(candidates)[source]

Find the rectangle that intersects least with rect in candidates

Parameters:: candidates (iterable of `ScreenArea`s) – The monitor areas to check for intersection
Returns:: The best candidate screen area, i.e. that has the smallest intersection
Return type:: ScreenArea

intersection(other)[source]

Compute the intersection of 2 screen areas

Parameters:: other (ScreenArea) – The screen area to compare with
Returns:: An area representing the intersection, or None if there is no intersection
Return type:: ScreenArea or None

equal(other)[source]

Check whether 2 areas cover the exact same space

Parameters:: other (ScreenArea) – The screen area to compare with
Returns:: True iff the areas are identical
Return type:: bool

contains(other)[source]

Check whether this area contains other

Parameters:: other (ScreenArea) – The screen area to compare with
Returns:: True iff the area is contained
Return type:: bool

intersects(other)[source]

Check whether this area intersects other

Parameters:: other (ScreenArea) – The screen area to compare with
Returns:: True iff the areas have an intersection
Return type:: bool

class pympress.util.Monitor(obj, id_=None, num=None)[source]

Bases: ScreenArea

A specialised ScreenArea representing a monitor, with an descriptive string and a monitor number

name = '': A str to represent a user-friendly name for the monitor

monitor_number = -1: An int that identifies the monitor in Display

static lookup_monitors(display, *windows)[source]

Get the info on the monitors

Parameters:

display (Display) – the current screen
*windows (tuple of Window) – windows for which to look up the monitor position

Returns:

The monitors for each window, followed by the best monitors for presenter and content

Return type:

tuple of Monitor

pympress.util.make_windows_dpi_aware()[source]: Set to avoid blurriness issues on High-DPI resolutions with scaling.
