Detailed Description

Annotated text gadget class.

Library: ilvatext

An instance of this class represents a contiguous zone of the text flow. IlvATZone instances can be nested but always in a hierarchical way, which may be ensured by checking whether the two boundaries of an IlvATZone belong to the same upper IlvATZone (or to no IlvATZone at all). The IlvAnnoText::insertZone() member function checks this. An IlvATZone is linked to an IlvATPalette which carries graphical information such as margins, font, foreground and background colors. It may have a specific IlvATInteractor or use the one assigned to its IlvATPalette. A user data field enables the storage of additional information specific to an instance of the IlvATZone class. This is useful, for example, when writing an IlvATInteractor assigned to an IlvATPalette instance. In this case, when an IlvATPalette instance is applied to any IlvATZone belonging to this IlvATPalette, it uses the user data information of the particular instance that triggers it (such as a hypertext interactor using information stored in the user data field of the IlvATZone to know what new file must be loaded).

Returns

The IlvAnnoText holding the IlvATZone.

IlvATInteractor* IlvATZone::getInteractor

(

)

const

Returns the interactor of the text zone.

Returns

The IlvATInteractor associated with the text zone, or, if no IlvATInteractor has been associated to it, a pointer to the IlvATInteractor associated with the IlvATPalette to which the current IlvATZone belongs; if the current IlvATZone doesn't belong to any IlvATPalette, or if its IlvATPalette doesn't have an IlvATInteractor attached, the function returns 0.

IlvATZone* IlvATZone::getParent

(

)

const

Returns the text zone immediately containing this zone.

Returns

The IlvATZone immediately containing the current IlvATZone or 0 is there are none.

IlvATPalette* IlvATZone::getTextPalette

(

)

const

Returns the IlvATPalette of the text zone.

Returns

The IlvATPalette associated with the text zone, or 0 if it has not yet been affected to an IlvATPalette.

IlAny IlvATZone::getUserData

(

)

const

Returns the user data of the text zone.

Returns

The user data (of type IlAny) associated with the IlvATZone.

(

IlvATInteractor *

inter

)

Sets the interactor of the text zone.

Parameters

inter

The interactor.

void IlvATZone::setUserData

(

IlAny

userData

)

Set the user data.
