Description:
The BaseContainer part is a subclassable sample part which demonstrates
several OpenDoc protocols such as registration, embedding, internalization,
externalization, cloning, multiple selection, drag/drop, and clipboard
operations. It is available on the Windows 95/NT, OS/2, and AIX platforms.
The BaseContainer part does not have intrinsic contents. Its contents
include only embedded frames. Subclasses of BaseContainer can define/add
intrinsic contents and let BaseContainer handle them optionally using its
generic 'Content Object' class.

How to Build:
To build this part you will need the OpenDoc Release 1.1 toolkit.
From the basecntr source directory run
nmake
To register the part with OpenDoc, run
nmake ForceRegistry
Usage:
To run the BaseContainer, issue the command:
docshell
and select "IBM BaseContainer Kind" from the dialog box.
Other parts can now be embedded in the BaseContainer.
Following editing operations can be performed on BaseContainer:
Embed -- Click on "Embed" pull-down menu of base container. A list
of all part handlers that are installed on the system is
displayed. This list is created dynamically when base
container is loaded. Select a part handler and click in
base container's client area to embed a part. BaseContainer
allows multiple levels of embedding.
Select -- An embedded part can be selected by 4 ways
1) Activate the embedded part and click on its activation border
2) If the embedded part is not active then Shift-Click or
Ctrl-Click on it
3) Lasso selection: Hold and drag left mouse button down in
BaseContainer's client area to get a selection rectangle.
All the embeds that are in the selection rectangle when the
mouse button is released are selected
4) Use 'Select All' menu option from 'Edit' menu.
BaseContainer allows multiple selection. Upon Ctrl-Click or
Shift-Click the selection state of the embed is toggled.
When the part is deactivated, all the selected parts are deselected.
Move -- Selection can be moved using the selection border. One cannot
move the selection outside the container's boundaries. A single
selected part can also be moved using 'Move' menu item in 'Edit'
menu.
Resize -- A selected part can be resized by stretching its corner or edge
selection handles. One can also use 'Resize' menu option from
'Embed' menu.
Delete -- Use 'Delete Selection' menu option from 'Edit' menu
Copy/Paste -- To copy selection, use 'Copy' menu option form 'Edit' menu.
To paste clipboard contents, select 'Paste' menu and then click
in client area of the active BaseContainer.
Drag/Drop -- Press drag-mouse-button in the client area of selection and
drag it to the desired location either in same docshell or
another one. Modifier keys can be used to force a drag-copy or
a drag-move.
Design Notes:
For information on how to subclass from the BaseContainer and
the ContentObject classes, see appendix D of the "IBM OpenDoc
Programming Guide."
Known Restrictions:
BaseContainer does not allow "Open As Window" functionality.
BaseContainer supports icon views, however, the thumbnail view is
not fully implemented yet. At this time it just displays a large icon
on a thumbnail size frame.
