- NAME
-
- Class: pageclass
- Superclass: baseclass
- Include File: <libraries/bgui.h>
-
- FUNCTION
-
- To provide a gadget which can keep track of "pages" of gadgets of
- which one is displayed at a time. The pages can contain a groupclass
- object which has a set of members or it can contain a single gadget.
-
- Objects from this class send out the following attribute pairs in
- their notification events:
-
- PAGE_Active - Currently active page number.
-
- pageclass/GRM_ADDMEMBER
-
- NAME
- GRM_ADDMEMBER -- Add a object to a page group.
-
- SYNOPSIS
- err = DoMethod( obj, GRM_ADDMEMBER, member, tag, data, ... );
-
- ULONG err;
- Object *member;
- Tag tag;
- ULONG data;
-
- FUNCTION
- This method can be used to add a member to an existing page group.
-
- INPUTS
- member - A pointer to the object which you want to add to the group.
- tag,data - This is simply a tagitem array terminated by a TAG_DONE.
- The following attributes are possible:
-
- LGO_Relayout -- Normally the group is layed-out again if adding the
- new member to the group succeeds. Setting this tag to FALSE prevents
- this so you may do that later calling GRM_RELAYOUT explicitly.
-
- RESULT
- err - TRUE uppon success, FALSE uppon failure.
-
- If this method was successfull you do not need to dispose of the added
- member anymore. This will be disposed of as soon as the group to which
- the member was added is disposed of.
-
- SEE ALSO
- GRM_INSERTMEMBER, GRM_REMMEMBER, GRM_REPLACEMEMBER
-
- pageclass/GRM_INSERTMEMBER
-
- NAME
- GRM_INSERTMEMBER -- Insert a member behind an existing member.
-
- SYNOPSIS
- err = DoMethod( obj, GRM_INSERTMEMBER, member, pred, tag, data, ... );
-
- ULONG err;
- Object *member;
- Object *pred;
- Tag tag;
- ULONG data;
-
- FUNCTION
- This method is basically the same as GRM_ADDMEMBER with the exception
- that you can determine the object after which the object is added.
-
- INPUTS
- member - A pointer to the object to insert.
- pred - This must point to the object after which the new member
- is inserted. You may set this to NULL in which case the new
- member is inserted at the start of the list.
- tag,data - Here you can pass a set of tagitems in which layout
- specific attributes can be defined. Please refer to the
- GRM_ADDMEMBER section for more information on the available
- attributes.
-
- RESULT
- err - TRUE uppon success, FALSE uppon failure.
-
- If this method was successful you do not need to dispose of the added
- member anymore. This will be disposed of as soon as the group to which
- the member was added is disposed of.

-
- NAME
- GRM_REMMEMBER -- Remove an object from the group.
-
- SYNOPSIS
- DoMethod( obj, GRM_REMMEMBER, member );
-
- Object *member;
-
- FUNCTION
- To remove an object previously added create time or with the
- GRM_ADDMEMBER, GRM_INSERTMEMBER, GRM_REPLACEMEMBER, methods.
-
- INPUTS
- member - A pointer to the object which is to be removed from the
- group.
-
- RESULT
- No return code specified.
-
- NOTE
- After the object has been removed you are responsible for disposing
- of the removed object.

- pageclass/GRM_REPLACEMEMBER
-
- NAME
- GRM_REPLACEMEMBER -- Replace an object with another.
-
- SYNOPSIS
- rep = DoMethod( obj, GRM_REPLACEMEMBER, rem, add, tag, data, ... )
-
- Object *rep;
- Object *rem;
- Object *add;
- Tag tag;
- ULONG data;
-
- FUNCTION
- This method can be used to replace a member of a group with another
- member.
-
- INPUTS
- rem - This should point to the object which is to be replaced.
- add - This should point to the object which is to replace the
- object described in "rem".
- tag,data - This is an array of attributes which control the way the
- new object is layouted. The attributes allowed here are
- exactly the same as the attributes you can use with the
- GRM_ADDMEMBER method.
-
- RESULT
- rep - A pointer to the replaced object uppon success, and NULL
- uppon failure.
-
- If this method was successful you do not need to dispose of the
- member which replaces the other member anymore. This will be disposed
- of as soon as the group to which the member was added is disposed of.
-
- You are however responsible to dispose of the object which you have
- replaced.

- pageclass/GRM_WHICHOBJECT
-
- NAME
- GRM_WHICHOBJECT -- Find the object at the specified coordinates.
-
- SYNOPSIS
- obj = DoMethod( obj, GRM_WHICHOBJECT, xy );
-
- Object *obj;
- ULONG xy;
-
- FUNCTION
- This method should be used to find out which object is located
- under the given X/Y coordinates.
-
- INPUTS
- xy - A 32bit unsigned integer which holds the horizontal
- coordinate in the upper 16 bits and the vertical coordinate
- in the lower 16 bits. The coordinates should be relative to
- the upper-left corner of the window.
-
- NOTE
- Please note that this method will only work properly when the window
- in which the page group is located is open.
-
- This method is primarily used for the tool tips but may also be useful
- for the application programmer.
-
- RESULT
- Returns the object under the coordinates or NULL if there is no object
- under the given coordinates.
-
- pageclass/OM_DISPOSE
-
- NAME
-
- OM_DISPOSE
-
- FUNCTION
-
- When this method is called it will also dispose of all

-
- pageclass/PAGE_Active
-
- 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
-
- (ISGNU).
-
- pageclass/PAGE_Inverted
-
- 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
-
- FALSE.
-
- APPLICABILITY
-
- (I).
-
- pageclass/PAGE_Member
-
- NAME

- (I).
-
- pageclass/PAGE_NoBufferRP
-
- 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 occurs 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
-
- FALSE.
-
- APPLICABILITY
-
- (I).
