Currently a gui_window is a top level browser object.
|
|
|
|
This has to be corrected. Instead a gui_window must simply be a render
|
|
target inside a non-user-sizable container which is capable of
|
|
scrolling around. I.E. a GtkViewport.
|
|
|
|
Thusly all routines which are callbacks for the viewport can remain
|
|
attached to a gui_window, all others must be migrated to a
|
|
gtk_scaffold concept which embodies the toolbar, statusbar,
|
|
blahblahblah.
|
|
|
|
If a gui_window wants to be able to scroll itself, it automatically
|
|
embeds itself in a GtkScrolledWindow which will provide scrollbars for
|
|
it. Otherwise it makes a call to its scaffold to ask it to attach its
|
|
scrollbars to the viewport.
|
|
|
|
The gui_window objects therefore are a GtkDrawingArea inside a
|
|
GtkFixed inside a GtkViewport (optionally inside a GtkScrolledWindow)
|
|
The GtkFixed's job (among other things) is to sit on its size_allocate
|
|
event and ensure that the GtkDrawingArea fills 100% of itself. (and is
|
|
on the bottom of the widget stack -- this happens automatically if the
|
|
drawing area is the first widget to be added to the GtkFixed and it is
|
|
never removed.)
|
|
|
|
The gtk_scaffold object must expose a call to show/hide (link/delink?)
|
|
its scrollbars so that if the contained gui_window becomes a frameset
|
|
then it can hide the scrollbars belonging to the top level window.
|
|
|
|
It must be possible to add gui_window objects to other gui_window
|
|
objects rather than to a gtk_scaffold so that frames can be embedded
|
|
appropriately.
|
|
|
|
The size-allocate event for the drawing area must pass through to the
|
|
underlying browser_window as currently it does.
