99437c4761 [text] Don't interpret the unicode value when the control modifier is on
When a letter key is pressed with the control key held down one of
three things will happen :-

a) If the stage is embedded within a GtkClutterEmbed the unicode value
   will be filled from gdk_keyval_to_unicode. This will be the same
   value as if control was not pressed (so Ctrl+V will be 'v').

b) If the stage is not in a GtkClutterEmbed and Clutter is running on
   the X11 backend then it will try to fill in the unicode value from
   XLookupString. This *will* take into account the control so the
   unicode value will represent a control character (Ctrl+V will be
   '\x16').

c) Most other backends will not bother to fill in the unicode
   value. Therefore clutter_keysym_to_unicode will be used which also
   does not take into account the control key (so Ctrl+V will be 'v').

For cut and paste to work in Nbtk, the control keys need to bubble up
to the parent NbtkEntry container. This works fine for 'b' but not 'a'
and 'c'.

This patch makes ClutterText always allow the event to bubble if the
key is not handled by the binding pool and the control modifier is
down.

Ideally ClutterText would always get a unicode value that takes into
account the modifiers but this is probably best left up to the input
methods.

5d7c2e7c44 Set LD_LIBRARY_PATH when running g-ir-compiler
g-ir-compiler currently opens the library for the .gir it is compiling;
to make that work we need to set LD_LIBRARY_PATH before running
g-ir-compiler to include .libs.

(I think this may have been working earlier because there was a
hack that substituted .so with .la and tried opening that; that
works for the incorrect libclutter-glx-1.0.so but not for the
correct libclutter-glx-1.0.so.0)

4c1248c5e9 Full fix for the G-I support in Clutter
Update the sed hack for the shared library to be more robust.

Remove the --shared-library command line argument from g-ir-scanner,
as no distribution will ever ship the .la files. This effectively
reverts commit 68f8a98cfb.

366e0f9cd7 Update Clutter to use G-I 0.6.4
Following bug #1762, the syntax of g-ir-scanner was changed in
gobject-introspection, so Clutter does not build anymore with 0.6.4.

See the bugzilla bug:

  http://bugzilla.gnome.org/show_bug.cgi?id=591669

GObject-Introspection now uses a different mechanism to extract the
SONAME when building the gir file and it needs the libtool archive as
option.

90d8f31831 [units] Do not be locale-dependant on string conversion
When dumping a ClutterUnits structure to a string we are using a bare
g_strdup_printf(), which unfortunately is locale dependant. So, for
instance, a type of CLUTTER_UNIT_EM and a value of 42 are stringified
as:

        C:      42.00 em
        en_GB   42.00 em
        it_IT   42,00 em
        fr_FR   42,00 em

This would not be a problem -- clutter_units_from_string() allows both
'.' and ',' as fractionary part delimiters. The test suite, on the
other hand, does not know that, and it checks for exact matches with
the C locale.

Calling setlocale(LC_ALL,"C") at the beginning of the conformance test
suite is not a good idea, because it would prevent external testing; and
it's a lame cop out from doing exactly what we have to do -- pick a format
and stick with it.

Like other platforms, languages and frameworks before us, we opt to
be less liberal in what we create; so, we choose to always stringify
ClutterUnits with fractionary parts using '.' as the delimiter.

f7edc97d8d Add new Atom atom_NET_WM_PID to set pid info
Clutter advertises itself on X11 as implementing the _NET_WM_PING protocol,
which is needed to be able to detect frozen applications; this allows us to
stop the destruction of the stage by blocking the CLUTTER_DELETE event and
wait for user feedback without the Window Manager thinking that the app has
gone unresponsive.

In order to implement the _NET_WM_PING protocol properly, though, we need
to add the _NET_WM_PID property on the Stage window, since the EWMH states:

  [_NET_WM_PID] MAY be used by the Window Manager to kill windows which
  do not respond to the _NET_WM_PING protocol.

Meaning that an unresponsive Clutter application might not be killable by
the window manager.

f25cdf066c [actor] Allow unsetting width and height separately
It is possible to unset the size of an actor specified with set_width()
and set_height() by using:

  clutter_actor_set_size (actor, -1, -1);

Which works by unsetting the :min-*-set and the :natural-*-set properties.

Calling set_width(-1) and set_height(-1) separately, though, doesn't work
thus implicitly breaking the assumption that set_size() is nothing more
than set_width()+set_height(). This was obviously due to the face that
pre-1.0 set_width() and set_height() took an unsigned integer as an
argument.

420ed353b5 [x11] Do not ask to destroy an empty Window
The fix for bug 1750 inside commit b190448e made Clutter-GTK spew
BadWindow errors. The reason for that is that we call XDestroyWindow()
without checking if the old Window is None; this happens if we call
clutter_x11_set_stage_foreign() on a new ClutterStage before it has
been realized.

Since Clutter-GTK does not need to realize the Stage it is going to
embed anymore (the only reason for that was to obtain a proper Visual
but now there's ClutterBackendX11 API for that), the set_stage_foreign()
call is effectively setting the StageX11 Window for the first time.

ad7dcc9896 [color] Fix HLS to RGB colorspace conversion
The HLS to RGB conversion in case the S value is zero is:

  R = G = B = luminance

ClutterColor uses a byte (0 to 255) for the R, G and B channels
encoding, while luminance is expressed using a floating point value
in the closed interval [0, 1]; thus the case above becomes:

  R = G = B = (luminance * 255)

The clutter_color_from_hls() code is missing the final step of
de-normalizing the luminance value, and so it breaks the roundtrip
colorspace conversion between RGB and HLS.

6a1506bd5f [text] Queue a redraw when the selection is cleared
If you select all the text in a ClutterText, there is an invisible
cursor position either at the beginning or end. If it's at the beginning,
the bug is that left arrow won't clear the selection. If it's at the end,
the bug is that the right arrow won't.

Here are the ways to reproduce it:

a. Ctrl-A selects all and moves the hidden cursor position to the left.
b. For single line: End, Shift-Home does the same.
c. Or manually moving to the end and doing Shift-Left Arrow to the
   beginning.

These all put it in the state where right arrow will properly clear
selection and move to cursor position 1, but left arrow fails to clear
the selection.

For b and c above, the opposite will give you the end case where right
arrow doesn't work.

Anyway, it turns out clear_selection is getting called, it just doesn't
show up because it's not doing a queue_redraw. So the attached patch
seems to fix things.

It might be desirable for some applications and/or platforms to get
every motion event that was delivered to Clutter from the windowing
backend. By adding a per-stage flag we can bypass the throttling

7b811f8be4 [stage] Force an allocation before showing the stage
A lot of applications change the size of the stage from the default
before the stage is initially shown. The size change won't take affect
until the first allocation run. However we want the window to be at
the correct size when we first map it so we should force an allocation
run before showing the stage.

There was an explicit call to XResizeWindow in
clutter_stage_x11_show. This is not needed anymore because
XResizeWindow will already have been called by the allocate method.

It would be useful inside a custom actor's paint function to be able to
tell if this is a primary paint call, or if we are in fact painting on
behalf of a clone.

In Mutter we have an optimization not to paint occluded windows; this is
desirable for the windows per se, to conserve bandwith to the card, but
if something like an application switcher is using clones of these windows,
they will not get painted either; currently we have no way of
differentiating between the two.

To help us handle sliced textures; When flushing materials there is an
override option that can be given to replace the texture name for layer0
so we may iterate the slices without needing to modify the material

Since improving the journal's ability to batch state changes we added a
_cogl_material_equals function that is used by the journal to compare
materials and identify when a state change is required, but this wasn't
correctly considering the layer0 override resulting in false positives that
meant the journal wouldn't update the GL state and the first texture name
was used for all slices.

df4429462f [cogl matrix stack] Create a client side matrix stack for the projection matrix
The cost of glGetFloatv with Mesa is still representing a majority of our
time in OpenGL for some applications, and the last thing left using this is
the current-matrix API when getting the projection matrix.

This adds a matrix stack for the projection matrix, so all getting, setting
and modification of the projection matrix is now managed by Cogl and it's only
when we come to draw that we flush changes to the matrix to OpenGL.

This also brings us closer to being able to drop internal use of the
deprecated OpenGL matrix functions, re: commit 54159f5a1d

37bd35f592 [actor] Allow changing the transformations matrix
Currently, the transformation matrix for an actor is constructed
from scenegraph-related accessors. An actor, though, can call COGL
API to add new transformations inside the paint() implementation,
for instance:

  static void
  my_foo_paint (ClutterActor *a)
  {
    ...
    cogl_translate (-scroll_x, -scroll_y, 0);
    ...
  }

Unfortunately these transformations will be completely ignored by
the scenegraph machinery; for instance, getting the actor-relative
coordinates from event coordinates is going to break badly because
of this.

In order to make the scenegraph aware of the potential of additional
transformations, we need a ::apply_transform() virtual function. This
vfunc will pass a CoglMatrix which can be used to apply additional
operations:

  static void
  my_foo_apply_transform (ClutterActor *a, CoglMatrix *m)
  {
    CLUTTER_ACTOR_CLASS (my_foo_parent_class)->apply_transform (a, m);
    ...
    cogl_matrix_translate (m, -scroll_x, -scroll_y, 0);
    ...
  }

The ::paint() implementation will be called with the actor already
using the newly applied transformation matrix, as expected:

  static void
  my_foo_paint (ClutterActor *a)
  {
    ...
  }

The ::apply_transform() implementations *must* chain up, so that the
various transformations of each class are preserved. The default
implementation inside ClutterActor applies all the transformations
defined by the scenegraph-related accessors.

Actors performing transformations inside the paint() function will
continue to work as previously.

Fixes and adds a unit test for creating and drawing using materials with

_cogl_material_flush_layers_gl_state will bind the fallback texture for any
COGL_INVALID_HANDLE layer, later though we could explicitly check when the
current blend mode does't actually reference a texture source in which case
binding the fallback texture is redundant.

33400c0aae [cogl] Improve ability to break out into raw OpenGL via begin/end mechanism
Although we wouldn't recommend developers try and interleve OpenGL drawing
with Cogl drawing - we would prefer patches that improve Cogl to avoid this
if possible - we are providing a simple mechanism that will at least give
developers a fighting chance if they find it necissary.

Note: we aren't helping developers change OpenGL state to modify the
behaviour of Cogl drawing functions - it's unlikley that can ever be
reliably supported - but if they are trying to do something like:

   - setup some OpenGL state.
   - draw using OpenGL (e.g. glDrawArrays() )
   - reset modified OpenGL state.
   - continue using Cogl to draw

They should surround their blocks of raw OpenGL with cogl_begin_gl() and
cogl_end_gl():

   cogl_begin_gl ();
   - setup some OpenGL state.
   - draw using OpenGL (e.g. glDrawArrays() )
   - reset modified OpenGL state.
   cogl_end_gl ();
   - continue using Cogl to draw

Again; we aren't supporting code like this:
   - setup some OpenGL state.
   - use Cogl to draw
   - reset modified OpenGL state.
When the internals of Cogl evolves, this is very liable to break.

cogl_begin_gl() will flush all internally batched Cogl primitives, and emit
all internal Cogl state to OpenGL as if it were going to draw something
itself.

The result is that the OpenGL modelview matrix will be setup; the state
corresponding to the current source material will be setup and other world
state such as backface culling, depth and fogging enabledness will be also
be sent to OpenGL.

Note: no special material state is flushed, so if developers want Cogl to setup
a simplified material state it is the their responsibility to set a simple
source material before calling cogl_begin_gl. E.g. by calling
cogl_set_source_color4ub().

Note: It is the developers responsibility to restore any OpenGL state that they
modify to how it was after calling cogl_begin_gl() if they don't do this then
the result of further Cogl calls is undefined.
2009-06-30 17:13:38 +01:00
Robert Bragg
6d9498da7c Adds a cogl_flush() to give developers breaking into raw GL a fighting chance
This function should only need to be called in exceptional circumstances
since Cogl can normally determine internally when a flush is necessary.

As an optimization Cogl drawing functions may batch up primitives
internally, so if you are trying to use raw GL outside of Cogl you stand a
better chance of being successful if you ask Cogl to flush any batched
geometry before making your state changes.

cogl_flush() ensures that the underlying driver is issued all the commands
necessary to draw the batched primitives.  It provides no guarantees about
when the driver will complete the rendering.

This provides no guarantees about the GL state upon returning and to avoid
confusing Cogl you should aim to restore any changes you make before
resuming use of Cogl.

If you are making state changes with the intention of affecting Cogl drawing
primitives you are 100% on your own since you stand a good chance of
conflicting with Cogl internals.  For example clutter-gst which currently
uses direct GL calls to bind ARBfp programs will very likely break when Cogl
starts to use ARBfb programs internally for the material API, but for now it
can use cogl_flush() to at least ensure that the ARBfp program isn't applied
to additional primitives.

This does not provide a robust generalized solution supporting safe use of
raw GL, its use is very much discouraged.

87f99e214a [cogl-material] Be more carefull about flushing in cogl_material_remove_layer
Previously we would call _cogl_material_pre_change_notify unconditionally, but
now we wait until we really know we are removing a layer before notifying the
change, which will require a journal flush.

Since the convenience functions cogl_set_source_color4ub and
cogl_set_source_texture share a single material, cogl_set_source_color4ub
always calls cogl_material_remove_layer.  Often this is a NOP though and
shouldn't require a journal flush.

This gets performance back to where it was before reverting the per-actor
material commits.

Since the journal puts material colors in the vertex array accumulated for

means using cogl_set_source_color4ub is no longer a concern.
