Instead of just passing the GdkContentFormats, we are now passing the
GdkContentProvider to gdk_drag_begin().
This means that GDK itself can now query the data from the provider
directly instead of having to send selection events.
Use this to provide the private API gdk_drag_context_write() that allows
backends to pass an output stream that this data will be written to.
Implement this as the mechanism for providing drag data on Wayland.
And to make this all work, implement a content provider named
GtkDragContent that is implemented by reverting to the old DND
drag-data-get machinery inside GTK, so for widgets everything works just
like before.
Instead, pass the actions as part of gdk_drag_begin() and insist DND is
always managed.
A new side effect is that gdk_drag_begin() can now return %NULL.
This is the replacement for selection usage.
Backend implementations for X11 (missing support for backwards compat
formats like COMPOUND_TEXT) and Wayland are included.
GTK code should be adapted to use gdk_drop_read_*() functions instead
of gtk_drag_get_data().
Drop the screen argument from gdk_dnd_find_window_for_screen
and rename the function to gdk_dnd_find_window. The screen
argument does not add anything here since the drag context
is already tied to the display. Update all backends, and
update all callers.
We should conform to a minimal set of reasons for the gtk side to emit
a better GtkDragResult than GTK_DRAG_RESULT_ERROR. This fixes the notebook
tab DnD feature, where we rely on GTK_DRAG_RESULT_NO_TARGET.
In the wayland side, unfortunately we can't honor either NO_TARGET nor
USER_CANCELLED, we don't know of the latter, so we could return false
positives on the former.
https://bugzilla.gnome.org/show_bug.cgi?id=761954
We've traditionally left GTK+ to handle the input side of things,
letting GDK only manage the windowing-specific messaging. This
way of splitting responsibilities is not compatible however with
some backends, we must fold then input management at the DnD stage
into GDK (and backends) domain.
The gdk_drag_context_manage_dnd() call is meant to be the entry
point for this mode of operation, if the drag and drop operation
becomes managed, the caller (i.e. gtkdnd.c) doesn't need to perform
grabs, nor manage input events itself.
As a consequence of this, different aspects now belong to the
backend GdkDragContext implementation:
- Because the caller doesn't see keyboard events anymore,
keyboard navigation must be managed in GDK, so is the decision
of the current action based on modifiers/button pressed.
- Because the caller won't see input events in general, the lifetime
of the drag and drop operation is now communicated through the
::drop-performed, ::dnd-finished and ::cancel events
- Because the caller doesn't participate anymore on the action
being chosen, the pointer cursor must be set by the backend.
The caller is rather notified of the final action through the
::action signal.
The caller is still responsible of dealing with the corresponding
GdkSelection, ensuring its ownership and communicating the supported
mimetypes.
Add a variant of gdk_drag_begin that takes the start position
in addition to the device. All backend implementation have been
updated to accept (and ignore) the new arguments.
Subsequent commits will make use of the data in some backends.
The previous function gdk_drag_get_protocol_for_display() took native
window handles, so it had to be changed. Because it didn't do what it
was named to do (it didn't return a protocol even though it was named
get_protocol) and because it doesn't operate on the display anymore but
on the actual window, it's now called gdk_window_get_drag_protocol().
This commit hides GdkDragContext and GdkDragContextClass, adds
vfuncs for most drag context functionality, and turns the X11 DND
implementation into GdkDragContextX11. We also add vfuncs to
GdkDisplay for gdk_drag_get_protocol and to GdkWindow for
gdk_drag_begin, and implemenet them for X11.
Other backends need similar treatment and are broken now.

platforms, as GdkNativeWindow has been guint32 for them
already.

2000-06-14 Havoc Pennington <hp@redhat.com>
* gdk/Makefile.am: add gdkpixmap.c
* gdk/gdk.c: s/gdk_window_init/_gdk_windowing_window_init/

ref/unref
* gdk/gdkcolor.h: make GdkColormap a GObject subclass
* gdk/gdkcompat.h: remove GdkWindowType compat, since
GdkWindowType is now non-deprecated;
change gdk_window_get_type() compat to be
gdk_window_get_window_type().
* gdk/gdkdnd.h: make GdkDragContext a GObject.
* gdk/gdkdraw.c, gdk/gdkdraw.h: Convert GdkDrawable to a pure
virtual GObject. Make all functions call into the vtable.
Move gdk_image_put() guts in here. Remove GdkDrawableType
and gdk_drawable_get_type(), these are now GdkWindow-specific.
draw_image, get_depth, get_size, set_colormap, get_colormap,
get_visual added to the vtable.
* gdk/gdkgc.h, gdk/gdkgc.c: Convert GdkGC to a pure virtual
GObject. Virtualize everything.
(gdk_gc_new_with_values): remove check for destroyed window,
because now GdkWindow::create_gc will check this.
(gdk_gc_set_values): New function to set GC values, this
was already implemented but wasn't in the header
* gdk/gdkimage.h, gdk/gdkimage.c: Convert GdkImage to a GObject.
* gdk/gdkinternals.h: Remove _gdk_window_alloc(), remove
_gdk_window_draw_image(), remove _gdk_windowing_window_class,
remove _gdk_window_class; add _gdk_window_impl_get_type() and
_gdk_pixmap_impl_get_type(). Rename gdk_window_init to
_gdk_windowing_window_init, rename gdk_image_init to
_gdk_windowing_image_init.
* gdk/gdkpango.c: Reflect GObject-ification of PangoContext.
(gdk_draw_layout): Remove check for destroyed window,
because all the drawable methods already check it.
* gdk/gdkpixmap.h, gdk/gdkpixmap.c: Convert GdkPixmap to GObject.
Add gdkpixmap.c which contains implementation of GdkDrawable
virtual table (by chaining to a platform-specific implementation
object).
* gdk/gdkprivate.h: Remove GDK_IS_WINDOW, GDK_IS_PIXMAP,
GDK_DRAWABLE_DESTROYED. Add GDK_WINDOW_DESTROYED. Replace
GDK_DRAWABLE_TYPE with GDK_WINDOW_TYPE. Remove GdkDrawablePrivate,
GdkWindowPrivate, GdkImageClass, GdkImagePrivate, GdkGCPrivate,
GdkColormapPrivate.
* gdk/gdktypes.h: #include <glib-object.h>
* gdk/gdkwindow.h, gdk/gdkwindow.c: Convert GdkWindow to GObject.
Move most functionality to platform-specific implementation
object. GdkWindow itself now handles the backing store, then
chains to the platform-specific implementation.
(gdk_window_get_window_type): return GdkWindowType of the window.
(gdk_window_peek_children): New routine, returns the children of
a GdkWindow
(gdk_window_get_children): Was in X11-specific code and did
XQueryTree. Changed to simply return a copy of window->children;
so it can go in cross-platform code.
* gdk/x11/Makefile.am: fix broken MKINSTALLDIRS path
* gdk/x11/gdkcolor-x11.c: implement X-specific parts of
GdkColormap; just changed to use the new private data instead
of casting to GdkColormapPrivate.
* gdk/x11/gdkcursor-x11.c: added a couple typechecks to
gdk_cursor_new().
* gdk/x11/gdkdnd-x11.c: Change the way we access private fields
(private data member in the GObject).
(xdnd_manager_source_filter): Function had broken
error handling, fix it (use gdk_error_trap_push).
* gdk/x11/gdkdrawable-x11.c: This file now implements
a base class for GdkWindowImplX11/GdkPixmapImplX11. This
base class is purely for the convenience of the X port,
and not part of the interface to cross-platform GDK.
* gdk/x11/gdkevents-x11.c: Reflect various renamings.
* gdk/x11/gdkgc-x11.c: Implement a subclass of GdkGC that's
specific to X, and returned by the create_gc virtual method
of GdkDrawableImplX11.
(gdk_x11_gc_set_dashes): Change this to take an array of gint8
rather than gchar, this was also changed in the GdkGC vtable.
(gdk_x11_gc_values_to_xvalues): If GdkGCValues is NULL, or the
mask is 0, return immediately, instead of checking every flag.
This is faster, and keeps us from segfaulting if values is NULL
and the mask contains some nonzero flags.
* gdk/x11/gdkgeometry-x11.c: deal with all the rearranging of
GdkWindow.
* gdk/x11/gdkglobals-x11.c: change type of grab window, since
GdkWindowPrivate is gone.
* gdk/x11/gdkim-x11.c: rename things that got renamed.
* gdk/x11/gdkimage-x11.c: implement in terms of GObject, and
remove the image_put stuff that got transferred to GdkDrawable.
* gdk/x11/gdkinput.c: renamings
* gdk/x11/gdkmain-x11.c: #include <pango/pangox.h>
* gdk/x11/gdkpixmap-x11.c: GObject conversion
* gdk/x11/gdkprivate-x11.h: indentation fixes
* gdk/x11/gdkproperty-x11.c: renamings
* gdk/x11/gdkselection-x11.c: renamings
* gdk/x11/gdkwindow-x11.c: Restructuring and renaming; this now
implements the platform-specific "impl" object.
Moved gdk_window_get_children to gdk/gdkwindow.c
* gdk/x11/gdkx.h: Remove all the private structs and private datas
that no longer exist. Add declaration of GdkGCX11 object here.
Fix all the macros to still work.
* gtk/gtk-boxed.defs: Remove GtkStyle, GdkColormap, GdkWindow,
GdkDragContext from the boxed types since they are now GObjects.
* gtk/gtkstyle.h, gtk/gtkstyle.c: Converted GtkStyle to a GObject,
moved xthickness/ythickness into the instance. GtkStyleClass
functions are now in the standard vtable for GtkStyle, so you have
to create a GObject subclass to write a theme engine.
(gtk_style_copy): fixed a leaked PangoFontDescription
(gtk_style_init): renamed gtk_style_realize, so gtk_style_init
can be the standard GObject function.
* Throughout GTK:
s/style->klass->[xy]thickness/style->[xy]thickness
s/pango_layout_unref/g_object_unref/
* gtk/gtkrc.h, gtk/gtkrc.c: Converted GtkRcStyle to a GObject.
* gtk/gtksocket.c: Use gdk_window_get_user_data() instead of
accessing GDK internals.
* gtk/gtkwidget.c: Use gdk_window_peek_children() instead of
accessing GDK internals.
