pyface.i_gui module¶
The interface of a pyface GUI.
-
class
pyface.i_gui.
IGUI
(adaptee, default=<class 'traits.adaptation.adaptation_error.AdaptationError'>)[source]¶ Bases:
traits.has_traits.Interface
The interface of a pyface GUI.
-
busy
= Bool(False)¶ Is the GUI busy (i.e. should the busy cursor, often an hourglass, be displayed)?
-
started
= Bool(False)¶ Has the GUI’s event loop been started?
-
state_location
= Str()¶ A directory on the local file system that we can read and write to at will. This is used to persist layout information etc. Note that individual toolkits will have their own directory.
-
static
allow_interrupt
()[source]¶ Override SIGINT to prevent swallowing KeyboardInterrupt
Override the SIGINT handler to ensure the process can be interrupted. This prevents GUI toolkits from swallowing KeyboardInterrupt exceptions.
Warning: do not call this method if you intend your application to be run interactively.
-
classmethod
invoke_after
(millisecs, callable, *args, **kw)[source]¶ Call a callable after a specific delay in the main GUI thread.
- Parameters
millisecs (float) – Delay in milliseconds
callable (callable) – Callable to be called after the delay
args – Arguments and keyword arguments to be used when calling.
kwargs – Arguments and keyword arguments to be used when calling.
-
classmethod
invoke_later
(callable, *args, **kw)[source]¶ Call a callable in the main GUI thread.
- Parameters
callable (callable) – Callable to be called after the delay
args – Arguments and keyword arguments to be used when calling.
kwargs – Arguments and keyword arguments to be used when calling.
-
classmethod
set_trait_after
(millisecs, obj, trait_name, new)[source]¶ Sets a trait after a specific delay in the main GUI thread.
-
classmethod
set_trait_later
(obj, trait_name, new)[source]¶ Sets a trait in the main GUI thread.
- Parameters
obj (HasTraits instance) – Object on which the trait is to be set
trait_name (str) – The name of the trait to set
new (any) – The value to set.
-
static
process_events
(allow_user_events=True)[source]¶ Process any pending GUI events.
- Parameters
allow_user_events (bool) – If allow_user_events is
False
then user generated events are not processed.
-

class
pyface.i_gui.
MGUI
[source]¶ Bases:
traits.has_traits.HasTraits
The mixin class that contains common code for toolkit specific implementations of the IGUI interface.
Implements: _default_state_location()
-

allow_interrupt
()[source]¶ Override SIGINT to prevent swallowing KeyboardInterrupt
Override the SIGINT handler to ensure the process can be interrupted. This prevents GUI toolkits from swallowing KeyboardInterrupt exceptions.
