This has several advantages:
- it's always readable, no matter how sick font/colors are.
- it does not mess up the buffer, which is a model that should not
contain temporary edit states.
- preediting does not clutter undo.
- it fixes the remaining bugs in the old preediting code because that
code is completely gone now.
In GIMP 2.6 dockrc did not contain the factory entries for the session
infos, so set that up manually if needed. Also take the opportunity to
add a copyright notice to dialogs.c since tha file is almost rewritten
by now...
gimp_paint_core_finish(): when bailing out early because nothing was
painted (e.g. because we repeatedly shift-click on the same pixel,
which doesn't advance the interpolation distance), don't forget to
call gimp_viewable_preview_thaw() or the drawable preview will be
frozen forever.
- Reset the IM context in much more situations, like on button_press
and when the text editor is initialized and halted (pretty much what
GtkTextView does).
- As a consequence, halt the rectangle text tool after the text tool
in control() because cancelling the IM preedit might cause a
re-framing of the layer because it resized.
- pause()/resume() the draw tool around gimp_text_tool_halt() so we
definitely avoid drawing atrifacts when the text tool is shut down
in the middle of an IM preedit. That pause/resume pair should have
been there from the beginning actually.
- most importantly, when the text changes and we set the buffer (as
happens when undoing), block the "changed" signal on the *buffer*
and not on the proxy (which doesn't even have a "changed"
signal). This was apparently something that happened during the
on-canvas editor merging.
- don't update the proxy when the layout changes, that's the wrong way
around. Instead, update the layout whenever the proxy changes,
remove lots of calls to update_layout() from the text editor and let
the "changed" callback on the buffer do its job of updating
everything.
Like that we start selecting on the very first click on an unframed
text layer alreadyand that we ignore clicks in dead space which had
unexpected results before. Also update all comments and move them
into the function.
Feed them into the text editor's IM context and into the proxy text
view's key bindings. Fixes input methods (e.g. entering of unicode
sequences seems to work flawlessly now).
There is no reason to recreate the layout when the cursor or selection
bound move, so remove the entire callback and all the signal
blocking/unblocking.
In button_press(), don't frame the item again and switch to selecting
mode on double and triple click events, we already did that when
receiving the normal button-press. Also clarify a comment.
Add regression test for hide/show of dock windows that makes sure that
dock window positions are kept after a hide/show cycle. Also introduce
a helper function gimp_ui_find_non_toolbox_dock_window().
Make sure that after we have set GTK_WIN_POS_MOUSE on a dialog created
with the dialog factory, it is eventually reset. Also remove the only
occurance of the DEBUG_FACTORY define.
- remove the button again.
- add a "box-mode" property to GimpTextOptions and a combo box.
- let the normal options -> proxy -> text mechanism do the setting.
- make sure we update the rectangle in some more situations.
- add utility function gimp_text_tool_frame_item().
