NAME
Class: pageclass
Superclass: baseclass
Include File: <libraries/bgui.h>
FUNCTION
To provide a gadget which can keep track of "pages" of gadgets from
which one is displayed at the time. The pages can contain a groupclass
object which has a set of members or it can contain a single gadget.
Object from this class sends out the following attribute pairs in
their notification events:
PAGE_Active - Currently active page number.
pageclass/Methods pageclass/Methods
NEW METHODS
None.
CHANGED METHODS
OM_DISPOSE -- When this method is called it will also dispose of all
pages of objects attached to this object.
pageclass/Attributes pageclass/Attributes
NAME
PAGE_Member -- ( Object * )
FUNCTION
To add a page of gadgets. The object may be a groupclass object having
any number of members or it may be a single gadget object.
Default is NULL. Applicability is (I).
NAME
PAGE_Active -- ( ULONG )
FUNCTION
Set the page number currently active (I.E. displayed on the window).
The active page is the only page that can receive input.
Default 0. Applicability is (ISGNU).
NAME
PAGE_NoBufferRP -- ( BOOL )
FUNCTION
When this attribute is set to TRUE the pageclass will tell the
layout engine not to setup a buffer RastPort which means that all
rendering occures on-screen. This may be handy when you use objects
which take some time to render like the colorwheel.gadget on 256
colour screens.
Default is FALSE. Applicability is (I).
NAME
PAGE_Inverted -- ( BOOL )
FUNCTION
To force the members added at create time to be AddHead()'ed to the
member list instead of AddTail()'ed. This is necessary for the
assembly macros of the BGUI package.
Default is FALSE. Applicability is (I).
