LinkControlToField¶

Qualified name: delphivcl.LinkControlToField

class LinkControlToField¶

Bases: CustomLinkControlToField

Links a list control to a field. The TLinkListControlToField class extends TCustomLinkListControlToField with published properties.

Tip: If the direction is bidirectional, then the control must support the IEditLinkObserver interface.

Type:: bool

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_”.

ComponentCount¶: Returns the owned component count

Components¶: Returns an iterator over the owned components
