...selection on the canvas
if the editor dialog is active do not copy to the
clipboard the text selected, copy it instead when
selected with keys <Shift>-left/right.
Pass a GeglRectangle to all gimp_prop_gui_*() functions, and set
the soft limits to the rectangle's extents if the GParamSpec
metadata's "unit" is "pixel-coordinate" or "pixel-distance".
In GimpSymmetryEditor, pass the image extents, in GimpOperationTool
pass the drawable extents.
Whereas some IME would just cancel any preediting on IM context reset,
others would commit their preedit (for instance Ibus-Hangul).
Unfortunately it is not necessarily immediate, even after
gtk_im_context_reset() and gtk_im_context_focus_out(), so when switching
text layer, any preedit text is committed on the new layer.
Let's recreate the IM context on abort to make sure we don't share any
input between text layers.
The IM should be the one taking care of it by sending the proper
signals, and I would assume this should be done when we run:
gtk_im_context_focus_out ().
But it doesn't and leaves a dangling styled preedit text on leaving
a text layer, either because the IME is not properly implemented (not
reacting to the context leaving the focused widget), or GTK+2 is bugged,
or maybe we just don't understand exactly how this all works. Anyway
let's explicitly clean preedit text, not waiting for preedit-end or
commit signals on IM abort.
With left gravity, the mark is moved back 1 character to the left of the
cursor, whereas with right gravity, it is right after newly-inserted
text. This resulted sometimes into non-deleted preedit characters.
I don't understand all the subtleties since the problem only occurred
for the first character of a text layer, at least in my tests.
Anyway now it should be good.
Japanese IME emits the preedit-commit before preedit-end (Hangul or
Unicode don't, but we could assume other IMEs may be doing the same).
As a consequence, the undo step was not pushed, thus breaking undo
history and consistency.
The solution is to simulate preediting end then restart when a commit
happens during preediting.
Since commit b593462, gimp_text_tool_apply() is a semi-public function
(only to be used from gimptexttool-editor.c). Therefore move it to the
"public functions" section.
Commit cd147a4 reintroduced the crash. The culprit was the idle function
gimp_text_tool_apply_idle() which may not have been processed when
gimp_text_tool_move_cursor() is called, resulting in inconsistencies
between the text in the text tool's pango layout and its buffer.
Force any pending text commits to be applied before moving the cursor.
In the text tool editor code, connect to GtkIMContext::preedit-start
and introduce a boolean text_tool->preedit_active which indicates that
a preedit is going on.
Remove the new preedit-removal code from gimp_text_tool_reset_im_context()
because it was not reflecting the IM's internal state and made things
worse. Instead, added gimp_text_tool_abort_im_context() which really
gets rid of any ongoing preedit by force.
In the main text tool code, check for preedit_active and if TRUE,
apply any edits directly widhout pushing undo steps. Factored out
gimp_text_tool_apply_list() for that purpose in order not do
duplicate a lot of code.
On undo and on button_press, force-abort any ongoing preedit. This is
the right thing to do on undo, but not really on button_press, but I
don't see another way to keep states consistent.
The new gimp_text_tool_im_delete_preedit() also makes sure that
text_tool->preedit_string is non-NULL when modifying the buffer,
so it can be used as indication whether or not a preedit is
going on (in order to skip undo stuff while preediting).
Rather than just discovering them by chance, a simple grep and some
search and replace are much more efficient! :-)
Cleaning only done on C and automake files.
In particular, I don't want the preedit foreground colors to be
displayed in the text style editor UI. They are only temporary hints
and should not be taken into account as user-chosen style.
When gtk_im_context_get_preedit_string(), we have to inspect the
returned Pango attributes, so that the preedit string can be displayed
in the expected fashion (i.e. as in other programs).
Some input methods in particular would even break the preedit strings
in several chunks of text displayed differently (for instance Japanese),
depending on the cursor position within the preedit string.
First of all, derive GimpFilterOptions from GimpColorOptions, not the
other way around, which was a sick way of magically showing the right
options for various tools. That approach has failed and needed
additional hacks to do the right thing. Simply have the right class
hierarchy and call the right tool options GUI constructors and done.
Remove gimp_histogram_options_gui(), we don't need histogram scale
controls in tool options when we already have them next to the
histograms in the tool dialogs.
Also remove gimp_histogram_options_connect_view() and use a simple
g_object_bind_property() instead.
Reduces members and all sorts of duplication and is a much better
abstraction of what it does. Also make it a lot smarter and
self-updating, chop up the apply() function and move its parts where
they belong. Also, it's now aware of selection changes and does the
right thing.
Don't abort GimpImageMapTool on selection changes, it now nicely
handles that.
see commit below, they are not needed any longer. Also call
gimp_image_map_tool_preview() from gimp_image_map_tool_create_map()
and remove more other calls to preview().
- call it in gimp_image_map_tool_get_operation() so
gimp_operation_tool_set_operation() doesn't need to call it
- gimp_image_map_tool_settings_import() doesn't need to call it because
importing settings changes the config object anyway
Instead, emit "notify" in the config object, which is a hack,
but a temporary one. If should be the right code tho, if only
Gegl pads would be normal properties...
... and improve input method UI. IM should not use some floating overlay
frame to display the preedit text. Instead it is now directly inserted
into the text tool box, as selected text. It permits redimensionning of
the text box while typing, and push the rest of the text when inserting
in the middle (instead of superimposing an overlay box over the current
text box, making everything unreadable).
Input methods still have a few more issues, but this fixes the main UI
weirdness as well as the crash with Hangul IM.
Change things so the guide is preferred over any color picking
interaction of the parent GimpColorTool. Needs a minor change in the
GimpCurvesTool subclass too.
