Since the order of docks in a dock window is arbitrary, it can never
be correct to only care about the first dock. Remove
gimp_dock_window_get_dock() and correct that code that made use of
it. (The function itself was introduced when there could only be one
dock per dock window.)
Move toolbox special casing into
gimp_dialog_factory_dialog_new_internal() and on the fly fix problems
with double toolboxes appearing and sometimes not appearing.
- in GimpText, make "text" and "markup" mutually exclusive, so that
whenever one is set to non-NULL, the other is cleared automatically.
- add gimp_text_buffer_has_markup() which returns TRUE if any char
in the buffer is tagged.
- in the text tool, only set "markup" on the text proxy if there is
actually markup in the buffer, and set "text" otherwise.
This way we don't push "text" *and* "markup" undos on each keystroke,
and undo compression works the way it did before.
In the drop callbacks, don't check if the GimpContainerView's container
contains the dropped item, it might be in a sub-container. Instead,
simply checking if the GimpContainerView knows the item is sufficient
(and also much simpler than a recursive container serach).
Instead, keep a list of tags to explicitely remove around (the list of
unchecked toggles), and remove only these tags, so the tags that have
no widget in the UI are not affected by the insert_tags logic.
Add gimp_text_buffer_get_iter_at_index() which does the reverse thing
than the already existing function gimp_text_buffer_get_iter_index().
Use the new function when cursor-navigation lines. Add "gboolean
layout_index" to both functions, which if TRUE indicates that the
passed in/out index is an index into the PangoLayout's content rather
than the text buffer's. When dealing with layout indices, take into
account the additional characters we insert into the serialized markup
(and thus the layout) for each character that is tagged with spacing.
Instead of including dialogs/dialogs.h everywhere, introduce
gimp_dialog_factory_get_singleton(). The dialog factory singleton is
still initialized by dialogs.c though.
Right now the assumption is that we never will have another dialog
factory instance around. There were so many problems before when we
had four of them, so let's just keep one of them around.
because it breaks the invariant that the pango layout used for
navigating in the on-canvas editor must be a 1:1 view on the text
buffer used for editing. Will have to fix that somehow...
We only have one dialog factory now, and
gimp_dialog_factory_from_name() doesn't provide compile-time type
safety, so use global_dialog_factory directly instead.
The copy doesn't do anything yet, but this will enable us to do
transformations on the buffer contents before turning them into
markup, and the other way around.
because we will soon use temporary buffers to turn stuff into markup
and back, and these temporary buffers won't have their tags registered
like the original GimpTextBuffer does.
Use gtk_text_buffer_begin_user_action() and end_user_action() to group
all text buffer operations triggered by a single editing operation.
Connect to the buffer's "end-user-action" signal instead of to
"changed", "apply-tag" and "remove-tag" separately, so we only update
the text proxy once per user editing.
Add a list of available baseline tags to GimpTextBuffer and
automatically create baseline tags as needed. They get serialized as
<span rise="value">, so add attribute and value parameters to the
buffer's tag_to_name() and name_to_tag() functions. Properly managing
the rise's amount is a TODO, currently each keystroke changes the
baseline by 1024 pango units, which might be whatever depending on the
output grid.
