class Statusbar(**properties: Any)

Superclasses: Widget, InitiallyUnowned, Object

Implemented Interfaces: Accessible, Buildable, ConstraintTarget

A GtkStatusbar widget is usually placed along the bottom of an application’s main Window.

A GtkStatusBar may provide a regular commentary of the application’s status (as is usually the case in a web browser, for example), or may be used to simply output a message when the status changes, (when an upload is complete in an FTP client, for example).

Status bars in GTK maintain a stack of messages. The message at the top of the each bar’s stack is the one that will currently be displayed.

Any messages added to a statusbar’s stack must specify a context id that is used to uniquely identify the source of a message. This context id can be generated by get_context_id, given a message and the statusbar that it will be added to. Note that messages are stored in a stack, and when choosing which message to display, the stack structure is adhered to, regardless of the context identifier of a message.

One could say that a statusbar maintains one stack of messages for display purposes, but allows multiple message producers to maintain sub-stacks of the messages they produced (via context ids).

Status bars are created using new.

Messages are added to the bar’s stack with push.

The message at the top of the stack can be removed using pop. A message can be removed from anywhere in the stack if its message id was recorded at the time it was added. This is done using remove.

CSS node

GtkStatusbar has a single CSS node with name statusbar.

Constructors

class Statusbar

classmethod new() → Widget: Creates a new GtkStatusbar ready for messages.

Methods

class Statusbar

get_context_id(context_description: str) → int

Returns a new context identifier, given a description of the actual context.

Note that the description is not shown in the UI.

Deprecated since version 4.10: This widget will be removed in GTK 5

Parameters:: context_description – textual description of what context the new message is being used in

pop(context_id: int) → None

Removes the first message in the GtkStatusbar’s stack with the given context id.

Note that this may not change the displayed message, if the message at the top of the stack has a different context id.

Deprecated since version 4.10: This widget will be removed in GTK 5

Parameters:: context_id – a context identifier

push(context_id: int, text: str) → int

Pushes a new message onto a statusbar’s stack.

Deprecated since version 4.10: This widget will be removed in GTK 5

Parameters:

context_id – the message’s context id, as returned by get_context_id()
text – the message to add to the statusbar

remove(context_id: int, message_id: int) → None

Forces the removal of a message from a statusbar’s stack. The exact context_id and message_id must be specified.

Deprecated since version 4.10: This widget will be removed in GTK 5

Parameters:

context_id – a context identifier
message_id – a message identifier, as returned by push

remove_all(context_id: int) → None

Forces the removal of all messages from a statusbar’s stack with the exact context_id.

Deprecated since version 4.10: This widget will be removed in GTK 5

Parameters:: context_id – a context identifier

Signals

class Statusbar.signals

text_popped(context_id: int, text: str) → None

Emitted whenever a new message is popped off a statusbar’s stack.

Deprecated since version 4.10: This widget will be removed in GTK 5

Parameters:

context_id – the context id of the relevant message/statusbar
text – the message that was just popped

text_pushed(context_id: int, text: str) → None

Emitted whenever a new message gets pushed onto a statusbar’s stack.

Deprecated since version 4.10: This widget will be removed in GTK 5

Parameters:

context_id – the context id of the relevant message/statusbar
text – the message that was pushed
