cbb1e74bb5 textview: Only create cairo context in gtktextdisplay.c
Everything else is done using GtkSnapshot now, including renaming the
draw_layer vfunc to snapshot_layer.

0b39631464 textview: Replace pixbufs by textures
This affects a few apis, such as gtk_text_iter_get_pixbuf,
gtk_text_buffer_insert_pixbuf and GtkTextBuffer::insert-pixbuf,
which have all been replaced by texture equivalents.

Update all callers.

And remove gtktextdisplay.h from the installed files.

6e178aede2 Use GdkRGBA for text attributes
Now that GtkTextAttributes is private, we can clean this struct
up a bit. The first step is to switch from GdkColor to GdkRGBA,
and adapt all users.

9d9088304c text view: Improve text rendering
Use the text CSS node for rendering text, and the selection node
for rendering selected text, avoid gtk_style_context_save, update
states of all CSS nodes, and use the proper states when querying
style properties.

bb786ac240 textview: Use a CSS node for selection rendering
Use a CSS node with name selection, like we do for entries
and labels. Unlike those widgets, we currently don't user
gtk_render_background, but just use the background color.
That will require more effort.

e02acc7d71 GtkTextDisplay: Use pango renderer alpha support

now that PangoRenderer can do alpha.

28063ee2e4 textview: add support for underline and strikethrough colors
This commit adds the GtkTextTag:underline-rgba and :strikethrough-rgba
properties and the necessary plumbing to apply these colors in GtkTextLayout.
With this change, you can alter the color of underlines including those
of type PANGO_UNDERLINE_ERROR.

You might want to alter the underline color to differentiate between
spelling and grammer mistakes. In code editors, it is convenient to
differentiate between errors and warnings.

Note that the GtkTextAppearance struct is public ABI and has no spare
room for new fields, so we are resorting to some tricky packing to store
the colors in the unused pixel field of the fg_color and bg_color structs.
This packing is accomplished by the macros in gtktextattributesprivate.h.

50c4fdbacd gtktextdisplay: Optimize GtkStyleContext usage 2014-11-26 18:10:55 -08:00
Benjamin Otte
91467a45fc stylecontext: Deprecate functions
- gtk_style_context_get_background_color()
- gtk_style_context_get_border_color()

Those functions shouldn't be used anymore, because they don't represent
anything from the CSS styling we support. The background color often
isn't used due to background images and there are actually 4 different
border colors (1 for each side) - if there isn't also a border image in
use.

48c6b3b4f4 gtk: Add get_type() function declarations for private objects
I'm adding a bunch of fixes for gcc complaining about
-Wmissing-declarations.

This set of patches makes private classes in gtk/*.c that use
G_DEFINE_TYPE() safe by adding definitions for the get_type() function
that can't be made static.

3610ef90c3 Revert part of "textview: Remove extra magic for drawing children"
This partially reverts commit df37446f9b.
The commit changed API that was public (or at least semi-public) and
it's not worth changing that.

The original bug should still be fixed.

df37446f9b textview: Remove extra magic for drawing children
Instead, just draw the children. The cairo code will keep track of
things, so there's no need to track things.
Also, the old code was doing it wrong.

2ef5844bac Introduce gtk_render_insertion_cursor
The new function provides an API that takes the PangoLayout and index
as input params, this way it handles strong and weak cursors internally
factoring out all code duplicated in the widgets that need to render
cursors.

3c6842222a Use the split-cursor setting for textview cursors
Explicitely check the split-cursor setting when drawing the textview
insertion cursor instead of relying on the cursor_direction set in the
textlayout. This makes the cursor drawin code more uniform with other
widgets in preparation to refactoring the cursor drawing code in a
shared function.

0bff1af7a2 Rework GtkTextView cursor code.
Move the handling of primary/secondary cursors to gtktextdisplay, which
makes code simpler and more consistent to how GtkLabel and GtkEntry
draw cursors, which is useful in preparation to further refactoring.

604292a404 Fixed textview rendering regression.
Background color was not painted on the whole tagged segment after
line breaking, this was due to the default ->prepare_run() function
wiping the internal PangoColors clean... fixed this by unconditionally
setting local rgba colors from prepare_run instead of comparing them
and bailing out.

d399a4acab Added GdkRGBA properties to GtkTextTag.
This now allows text view to render text with alpha values in
the text foreground and backgrounds, the work is almost complete,
currently the error-underline-color is still a GdkColor style property
and since we use only GdkRGBA for rendering it needs to be converted
and applied, probably a new rgba version of the style property should
also be introduced.

This commit adds tests/testtextview that must be run from the tests/
directory to show translucent text in action.

c647085e76 textview: Translate the cairo context instead of keeping y value
This avoids overflow when transforming a large value to a pango unit.
To reproduce the problem:
seq 200000 > test.txt && tets/print-editor test.txt
Then scroll to around line 140.000 to see it (depends on font size of
course).

001697a22a Move the get_cursor_color in GtkStyleContext
Move the private get_cursor_color method belongs to StyleContext. Change
the api so that retrieving both primary and secondary color is possible.
I left the method private for now, though it should probably be public
as all the other getters.

ab656b3f7a Obtain the fg color from the renderer
prepare_run must have been called before draw_shape, so we can avoid
