It is enough to just set the parent (and make the parent
call gtk_native_check_resize in size_allocate).
This commit removes the relative_to argument to the
constructors of GtkPopover and GtkPopoverMenu, and
updates all callers.
The preview widget harks from a platform before time, when we didn't
have GIO, or a thumbnail specification.
Very few applications use it correctly, if at all; it has an horrid hack
to deal with the ownership of the widget's instance when accessed
through the getter function; it messes up the layout of the widget and
its label is less than useful when it comes to file names longer than a
dozen characters; it's a poor substitute for a proper thumbnail view.
GtkFileChooser's API predates GIO by a few years, so it started off with
filenames and URI as character arrays. After introducing GIO as a
dependency, the API included GFile-based entry points.
It's much more appropriate to use GFile everywhere, as we want to
encourage people to use GIO instead of passing random bytes to low level
POSIX API.

... and use one controller per button instead of using it on the
switcher and then going through lots of pain attempting to find the
right button for the location under the mouse.
Emit crossing events - with a new GTK_CROSSING_DROP type - like we do
for motion events. There is no more special casing for them.
Note that the gesture has not been updated yet, so some obscure behavior
may occur.
And in particular, only do it if the widget doesn't use ALIGN_FILL.
This avoids lots of measuring in the common case and speeds up
size_allocate() by about 25%.
And because size_allocate() is the bottleneck in the fishbowl, this also
gets ~25% more fishies.
Widgets should be given the actual size they will be allocated, so they
can do something with it.
If they want to clamp themselves to their natural size, nothing's
stopping them, they know their natural size after all.
It's the native's job to request a 1px x 1px size, not the job of
gtk_widget_size_allocate()
Also saves 10% of size_allocate() time because checking for an interface
is really expensive.
FIXME: Is this necessary?
Could the surfaces just clamp to 1x1 themselves?
We recently declared that surfaces can decide on whatever size they want
so natives need to inspect the size they requested anyway.
We are using (dddd) variants to store colors in variants,
which is dangerous now that GdkRGBA members are just floats.
Avoid passsing the GdkRGBA members directly to any varargs
functions.
We don't want to expose the GtkCrossingData struct, and manually
feeding events to event controllers is not something we want to
encourage, going forward.
Split the focus tracking into a separate
GtkEventControllerFocus, and change the API one more time.
We are back to having ::focus-in and ::focus-out signals.
Update all users.
Add fields for direct descendents to GtkCrossingData,
and populate them when emitting focus change events.
Also add accessors for these fields to GtkEventControllerKey,
and verify that they are set properly in the focus test.
Not done yet: Do the same for pointer crossing events.
Restructure the getters for event fields to
be more targeted at particular event types.
Update all callers, and replace all direct
event struct access with getters.
As a side-effect, this drops some unused getters.
Instead of relying on gdk's antiquated crossing events,
create a new GtkCrossingData struct that contains the
actual widgets, and a new event controller vfunc that
expects this struct. This also saves us from making sense
of X's crossing modes and details, and makes for a
generally simpler api.
The ::focus-in and ::focus-out signals of GtkEventControllerKey
have been replaced by a single ::focus-change signal that
takes GtkCrossingData as an argument. All callers have
been updated.
We want to make events readonly, so stop translating
their coordinates and instead pass the translated
coordinates separately, when propagating events.
This is triggered by typing / or hitting Ctrl+L. Since we don't have a
visual indicator for this mode right now anyway, the reason for not
allowing it in recent mode cited in the comment just above the
early-exit is irrelevant.
Closes#2178
Replace the gdk_surface_move_to_rect() API with a new GdkSurface
method called gdk_surface_present_popup() taking a new GdkPopupLayout
object describing how they should be laid out on screen.
The layout properties provided are the same as the ones used with
gdk_surface_move_to_rect(), except they are now set up using
GdkPopupLayout.
Calling gdk_surface_present_popup() will either show the popup at the
position described using the popup layout object and a new unconstrained
size, or reposition it accordingly.
In some situations, such as when a popup is set to autohide, presenting
may immediately fail, in case the grab was not granted by the display
server.
After a successful present, the result of the layout can be queried
using the following methods:
* gdk_surface_get_position() - to get the position relative to its
parent
* gdk_surface_get_width() - to get the current width
* gdk_surface_get_height() - to get the current height
* gdk_surface_get_rect_anchor() - to get the anchor point on the anchor
rectangle the popup was effectively positioned against given
constraints defined by the environment and the layout rules provided
via GdkPopupLayout.
* gdk_surface_get_surface_anchor() - the same as the one above but for
the surface anchor.
A new signal replaces the old "moved-to-rect" one -
"popup-layout-changed". However, it is only intended to be emitted when
the layout changes implicitly by the windowing system, for example if
the monitor resolution changed, or the parent window moved.
Changing the autohide property means the popover needs to be remapped.
Remapping may need user interaction, so lets just unrealize the popover
if the property changes, forcing the application to remap it should it
be shown again.
Add properties, and use string arrays instead of lists.
Among other things, this renames gtk_icon_theme_list_icons
to gtk_icon_theme_get_icon_names.

By running it in the capture phase, it will not be starved for events by
the button's click source and make drags actually start a color drag
operation.
Actually use GValues for the DND operation instead of sending GBytes of
pointer addresses through pipes.
This is a bit complicated because we need to special-case rootwindow
drops, because they're handled on the source side, so we need a custom
ContentProvider.
Enter the Emoji inseration in the undo history.
Also, stop stashing away the selection when we
pop up the Emoji chooser, and use the selection
as-is when we insert the Emoji.
The old code did mimetype checks everywhere when type compatibility has
since been moved to the GtkDropTarget::accept signal.
So the code can now just assume a compatible mime type exists.
Content providers are meant to be immutable, apart from very special
cases, but in those cases they need to emit
gdk_content_provider_content_changed().
Having a constructor that just uses a get_func invites abuse of this
by not making developers aware of those requirments.
In fact, all users in GTK failed to do this.
Instead, code should use the GtkDragSource::prepare signal to create
content providers when needed.
The same problem exists with gdk_content_provider_new_with_formats(),
but this commit doesn't touch that.
In Vala and JS at least, gtk_widget_get_css_name() and
gtk_widget_class_get_css_name() are resolved to
GtkWidget.get_css_name().
To avoid this problem, we rename the class version.
Accessors like these are weird to have and we can add widgets to the
content area via gtk_container_add() as well as add widgets to the
action area via gtk_info_bar_add_action_widget().
