ActionList¶

Qualified name: delphivcl.ActionList

class ActionList¶

Bases: CustomActionList

TActionList maintains a list of actions that can be used by components and controls such as menu items and buttons. Use Action lists to centralize the response to user commands (actions). Action list components maintain a list of actions that are available to the client controls in an application. Add action list components to your form or data module from the standard page of the component palette. Double-click the action list to display the Action List editor, from which you can add, delete, and rearrange actions.

Note: While it is possible to maintain the actions for an application using TActionList, it can be simpler to use Vcl.ActnMan.TActionManager instead.

Methods

`BindMethodsToEvents`	Connects methods to component events if they are named using the following pattern: Prefix_ComponentName_EventName.
`GetParentComponent`	Returns the parent of a component.
`HasParent`	Indicates whether the component has a parent to handle its filing.

Attributes

`ActionCount`	Indicates the number of actions in the action list.
`Actions`	Lists the actions maintained by the action list.
`ClassName`	Returns the TObject.ClassName
`ComObject`	Specifies the interface reference implemented by the component.
`ComponentCount`	Returns the owned component count
`ComponentIndex`	Indicates the position of the component in its owner's Components property array.
`ComponentState`	Describes the current state of the component, indicating when a component needs to avoid certain actions.
`ComponentStyle`	Governs the behavior of the component.
`Components`	Returns an iterator over the owned components
`DesignInfo`	Contains information used by the Form designer.
`Images`	CustomImageList:
`Name`	Specifies the name of the component as referenced in code.
`Observers`	Indicates the TObservers object added to the TComponent.
`Owner`	Returns the Component Owner
`State`	Indicates whether the actions in the action list respond when the user triggers a client object.
`Tag`	Stores a NativeInt integral value as a part of a component.
`VCLComObject`	Represents information used internally by components that support COM.

ActionCount¶: Indicates the number of actions in the action list.

Actions¶: Lists the actions maintained by the action list.

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

GetParentComponent()¶: Returns the parent of a component.

HasParent()¶: Indicates whether the component has a parent to handle its filing.

Images¶: CustomImageList:

Owner¶: Returns the Component Owner

State¶

Indicates whether the actions in the action list respond when the user triggers a client object. State can be one of the constants defined in the TActionListState type: asNormal, asSuspended, and asSuspendedEnabled.
