Rememeber if image windows are opened because we want the
gimp_session_info_restore() code to run for the single-image window
once that code is in place.
When we get to gimp_dialog_factory_dialog_configure() and do
gimp_session_info_read_geometry(), the window geometry has not yet
been updated, i.e. gimp_session_info_read_geometry() gives the session
info the size of the *previous* configure event.
Solve this by giving gimp_session_info_read_geometry() the configure
event so it can use that size when availble.
If we don't do this change, then we get bogus values of the size of
image window when repeatedly switching between single- and
multi-window mode.
In gimp_session_info_restore() there is code to create a dialog from a
session info. GimpSessionInfo lives in the widgets module. Thus we
can't add restoration code that depends on a higher level module. In
particular, we can't add code to restore docks in an GimpImageWindow
since GimpImageWindow lives in the display module. And we need such
code to be able to restore a single-window mode session.
Since dialogs are defined in the dialogs module, it makes sense to
also have the code that restores a dialog in that module.
So, add a 'restore_func' member to GimpRestoreDialogFunc of type
GimpRestoreDialogFunc and move the code there.
Add GimpDockContainer::get_dock_side() and write that info in the
sessionrc file. In single-window mode, a dock can be either on the
left or right side of the image window. In a dock window however, the
side concept doesn't apply ('side' has nothing to do with what column
a dock is in in a GimpDockColumns)
Add image_window boolean to GimpDialogFactoryEntry and rename
FOREIGN_NOT_HIDEABLE() to IMAGE_WINDOW(). We need to treat image
windows a bit special when we restore a single-window mode session.
Make GimpDockContainer::get_docks() return a new list and not just a
pointer to a list so that GimpImageWindow can implement it (who needs
to merge its two GimpDockColumns lists).
Don't set the first page of the restored dockbook active if there are
less than two pages. Also add a comment that explains why we return
the dockbook even though we know that all its dockables failed to
restore.
Make GimpDockWindow implement the GimpDockContainer interface. The
plan is to make GimpImageWindow also implement the GimpDockContainer
interface when we start to session manage docks in single-window mode.
We now have to classes that contain docks, GimpDockWindow and
GimpImageWindow (in single-window mode). Introduce a GimpDockContainer
interface so we can cope with these in an abstract way.
Rename GimpSessionInfoDock::identifier to dock_type, because it isn't
really an identifier; there might be several instance with dock_type
being "gimp-dock". This is a preparation for adding an actual
'identifier' member.
which allows to restrict the scale to a range that is smaller than
that of the model GtkAdjustment. This way we can enter large values in
the entry or by dragging beyond the end of the scale, but keep a
reasonably usable scale range for "normal" values.
