LinkPropertyToFieldDelegate¶
Qualified name: delphivcl.LinkPropertyToFieldDelegate
- class LinkPropertyToFieldDelegate¶
Bases:
BindComponentDelegateIs a binding component that wraps another binding component and references a component property, data source, and field name. The TLinkPropertyToFieldDelegate class implements a binding component that wraps another binding component and references a component property, a data source, and a field name. For more information regarding the delegates, please refer to the New LiveBinding topic, the Quick Binding Components Reference section.
Methods
TComponent.BindMethodsToEvents(prefix) Connects methods to component events if they are named using the following pattern: Prefix_ComponentName_EventName.
TComponent.GetParentComponent() Returns the parent of a component.
TComponent.HasParent() Indicates whether the component has a parent to handle its filing.
Attributes

Returns the owned component count
ComponentIndexIndicates the position of the component in its owner's Components property array.
Specifies the name of the property of the component that this wrapping binding component references.
ComponentStateDescribes the current state of the component, indicating when a component needs to avoid certain actions.
ComponentStyleGoverns the behavior of the component.
Returns an iterator over the owned components
ControlComponentSpecifies the component that will be bound to the source component, by means of LiveBindings.
Specifies a TDataSource object to which this delegate component links.
DesignInfoContains information used by the Form designer.

- BindMethodsToEvents(prefix)¶
Connects methods to component events if they are named using the following pattern: Prefix_ComponentName_EventName. Example: def handle_button1_OnClick(Sender): pass The function returns a list of tuples. Each tuple contains the name of the component, the name of the event and the method object assigned to the event. Note that the prefix parameter is optional and will default to “handle_”.

Returns the owned component count
- ComponentProperty¶
Specifies the name of the property of the component that this wrapping binding component references.
