pub struct Statusbar { /* private fields */ }
Expand description

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

An example GtkStatusbar

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 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

Statusbar has a single CSS node with name statusbar.

Implements

WidgetExt, glib::ObjectExt, AccessibleExt, BuildableExt, ConstraintTargetExt, WidgetExtManual, AccessibleExtManual

Implementations

Creates a new Statusbar ready for messages.

Returns

the new Statusbar

Creates a new builder-pattern struct instance to construct Statusbar objects.

This method returns an instance of StatusbarBuilder which can be used to create Statusbar objects.

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

Note that the description is not shown in the UI.

context_description

textual description of what context the new message is being used in

Returns

an integer id

Removes the first message in the Statusbar’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.

context_id

a context identifier

Pushes a new message onto a statusbar’s stack.

context_id

the message’s context id, as returned by gtk_statusbar_get_context_id()

text

the message to add to the statusbar

Returns

a message id that can be used with remove().

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

context_id

a context identifier

message_id

a message identifier, as returned by push()

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

context_id

a context identifier

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

context_id

the context id of the relevant message/statusbar

text

the message that was just popped

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

context_id

the context id of the relevant message/statusbar

text

the message that was pushed
