class opalone._internal.widget_signals.WidgetSignal(signal_id, panel_id, project_id, signal_type=None, data_type=None, path=None)
Panel

Bases: Signal

A widget signal is a signal that is owned by a Widget.

Parameters:

  • signal_id (str) – The ID of the signal.

  • panel_id (str) – The ID of the Panel that contains the widget that owns this signal.

  • project_id (str) – The ID of the Project that owns the signal.

  • signal_type (str | DatapointType) – The type of signal.

  • data_type (Data) – A data value holder.

opalone._internal.widget_signals.WidgetSignal.connect_to
opalone._internal.widget_signals.WidgetSignal.connect_to
connect_to(datapoint, is_enabled=True, force_enable=False)
Panel
bgColorunset

Connect the current datapoint to another datapoint.

If the connection to create is enabled, i.e. is_enabled=True, and any datapoint in this new connection is actively connected to another datapoint, then some connection rules will apply and the new connection might be declared invalid. If force_enable=True, conflicting connections will be disabled in favor of the new connection.

Some data types are incompatibles between one another, so that might result in an invalid connection. For example, a STRING data type cannot connect to a NUMERIC data type.

If the backend reports the connection to be invalid, this method will attempt to connect the other way around. For example, if A.connect_to(B) fails on the backend, this method will attempt the equivalent of B.connect_to(A). If this connection also fails, the first failure will be reported to the user.

Parameters:

  • datapoint (str | Datapoint) – The datapoint to connect to, either an ID or a datapoint object..

  • is_enabled (bool) – A flag to enable (True) or disable (False) the connection to create.

  • force_enable (bool) – A flag to drop (True) or not (False) any conflicting connections that already exist in the system.

Returns:

A new connection instance

Return type:

Connection

Get the alias of the datapoint.

This property returns an AliasWrapper, which behaves like a string but also provides additional methods like generate(). If the alias is not set, it initializes with an empty AliasWrapper.

Returns:

The alias of the datapoint.

Return type:

AliasWrapper | None
