These ended up square in the various refactors. Make them again L-shaped
by extending these along the edge being checked. This means we have to
check for corner positions in all edges, though.
In order to do this, leverage smooth scroll handling into the capture
phase scroll controller, controlled by ::scroll-begin in the propagation
phase controller.
There's 2 cases here:
- A child widget handles scroll. The scrolled window does not get
::scroll-begin, the child widget handles the full scroll sequence.
- No child handles scroll, the scrolled window gets ::scroll-begin,
and transfers control of scrolling to the capture phase controller.
As scrolling is performed, the pointer may fall into scrollable children,
but the scrolled window will be capturing the scroll events, so these
won't be seen by the child widgets.
Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/593
We let smooth scroll events that don't trigger a ::scroll signal through.
This is unintended, these are handled, even if just accumulated.
This fixes cases like GtkSpinButton inside GtkScrolledWindow, where both
would handle events, until the GtkSpinButton eventually shifts away from
underneath the pointer.

This code was here in gtk3 to cater for the completion window being
positioned. That was only to meant once as long as the completion window
was shown.
This doesn't work as well for gtk4, ::size-allocate gets propagated from
the toplevel, so happens much more often for the completion window, this
ends up with the completion position being reset to the first row
frequently.
Do this simply once when popping up the completion, instead.

The coordinates are already widget-local here, not transformed by the
adjustment positions. Using the adjustment value here ends up pushing
the entry far from the left border.
The correct minimum value here is 0, which matches the treeview left
border.

Let model buttons handle unpaired releases, these may happen indirectly
e.g. due to other child menus being opened at the time. Clicking would
dismiss the menu, but the menu item beneath the pointer would not get
activated.
We can handle that button release though via ::unpaired-release, so
there's no second click required.
Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/3463
Tracking it through the GtkGestureClick becomes a bit cumbersome for
handling of simultaneously pressed buttons. We can track ::stopped,
but that also emits for a number of situations where we want drag to
continue.
However, the GtkGestureDrag is grouped with the click gesture, and
knows better when to finish the drag gesture (not just because of a
button release), so hook drag and zoom mode finalization there.

Having a property with the same name of a method makes some languages
which put properties and method names in the same flat namespace not
really happy about our choices. To avoid collisions, let's put the the
"fullscreen" property into the past, alongside the "maximized" property.
Drop the "don't write code that crashes" folksy bit; don't start
sentences with conjunctions; remove copy-pasted references to
"iconified" states; point to the corresponding property notification in
a consistent manner.
Currently, the implicit grab is broken on the first button release,
in the case of pressing multiple buttons simultaneously. This means
that we emit crossing events early, and the next button releases
are sent to the pointer focus widget instead.
Consider the implicit grab effective until all buttons are released,
and only unset the pointer implicit grab (and emit crossing events)
after there are no further buttons pressed. We do this by checking
event modifiers, given button release events do contain the modifiers
in effect at the time the event was generated, we have to look for
exactly one active button modifier.
Fixes weird pointer states after pressing multiple buttons on a
widget.

It was used by all surfaces to track 'is-mapped', but still part of the
GdkToplevelState, and is now replaced with a separate boolean in the
GdkSurface structure.
It also caused issues when a widget was unmapped, and due to that
unmapped a popover which hid its corresponding surface. When this
surface was hidden, it emitted a state change event, which would then go
back into GTK and queue a resize on popover widget, which would travel
back down to the widget that was originally unmapped, causing confusino
when doing future allocations.
To summarize, one should not hide widgets during allocation, and to
avoid this, make this new is-mapped boolean asynchronous when hiding a
surface, meaning the notification event for the changed mapped state
will be emitted in an idle callback. This avoids the above described
reentry issue.
This makes it possible to set 'maximized' to true in .ui files, and the
window will show up maximized.
gtk_window_is_maximized() will return the intended maximized state until
actually mapped, it will then show the actual maximized state. The same
applies to reading the property.
This commit changes the behavior of window size computation and the
default size properties to:
* The default-width and default-height properties are updated to the
current window size unless the size is fixed by e.g. being maxmized,
tiled etc.
* The compute-size semantics are to just pick the default size, or if
not adequate, use the measured size, and consequently update the
default size, unless unresizable.
* gtk_window_get_size() is removed, what's more likely relevant is the
gtk_window_get_default_size() which will now contain more sensible
values.
Various places that used gtk_window_get_size() were updated to use
gtk_window_get_default_size() to remember and restore previous sizes.
This also changes the default value of 'default-width' and
'default-height' from -1 to 0. The gtk builder simplify tool is taught
how to omit when the default size is set to both -1 and 0.
This fixes an issue where the focus of the window continuously received
fake motion events even when a popover was open, making input events end
up behind the popover.
It also adds a comment describing why motion events are requested. Note
that popovers won't work with this, and it's possible both in the past
and now that sporadic missplaced motion events will appear, e.g. when a
window changes allocation but a popover is open.
While the workaround hides majority of the issue there are still two big downsides:
- shadow does eat from the widget dimensions so alignment is broken
- situations like popover going upwards on screen edge break completely
The appropriate action is to revert these theme duct tape solutions to make room
for a proper fix.
This reverts commit b3dba1dca6.
Issue https://gitlab.gnome.org/GNOME/gtk/-/issues/1987
This removes the gdk_surface_set_shadow_width() function and related
vfuncs. The point here is that the shadow width and surface size can now
be communicated to GDK atomically, meaning it's possible to avoid
intermediate stages where the surface size includes the shadow, but
without the shadow width set, or the other way around.
This changes allocation of the widget trees to happen as a side effect
to the GdkSurface::layout signal, which first passes the GtkNative
instance where it is then forwarded to the implementations of the
GtkNative interface.
The implementations of GtkNative are the ones doing the actual
gtk_widget_allocate(), and they do so in their GtkNativeClass::layout
function.
The size should correspond what gtk_widget_measure() does, and it
measures what's within the window excluding the shadow; so make this
helper function correspond to this.
Showing before the child would result in bogus
gdk_drag_surface_present() with an "empty" (1x1) size. This can easily
be avoided by postponing showing until there is anything to show.
By moving popup layout emission to the layout phase, the current
GdkPopup::poup-layout-changed signal has no value on its own as it'd be
ignored by GtkPopover.
Make the Wayland backend communicate the popup layout changes via the
common signal; but leave the rest intact until other backends catch up.
Don't have GtkRoot listen directly to the layout signal on the frame
clock, but let it pass through GdkSurface. This will allow GdkSurface to
be more involved in the layout phase.
We need to tell people what signal will be emitted when calling
gtk_widget_activate(), and that the shortcuts API might be more
appropriate to what they are looking for.
Setting a field on a class structure is not always an easy task from
languages other than C. While bindings can provide access to the class
pointer, twiddling the fields in the class structure can be awkward.
Additionally, signal ids are not always readily available.
We can paper over the direct access to the class structure, as well as
the "signal name to id" mapping with a simple couple of setter
functions.
This broke when we started using GDK_PROFILER_CURRENT_TIME for
timekeeping - that gets defined to 0 when we're building without
sysprof, so we can use it to make such determinations. Go back
to using g_get_monotonic_time().
Fixes: #3438
This ensures that we don't leak window references inside the action muxer.
Otherwise, we risk not disposing the windows upon gtk_window_destroy()
and blocking the main loop from quitting.
Fixes#3419
This comes complete with animation support. For a good time, try:
@keyframes conic {
100% { background-image: conic-gradient(from 1turn, red, lime, blue, yellow, red); }
}
window {
background-image: conic-gradient(red, lime, blue, yellow, red);
animation: conic infinite linear 5s;
}
We only needed the widget to get its action muxer. And this way we don't
have to call gtk_widget_get_action_muxer() dozens of times, just once in
set_widget().
The get_size() vfuncs is deprecated in GTK3, and only used as a
fallback path for cell renderers that do not implement preferred
size virtual functions.
We have code in place to handle a NULL node in the state when dealing
with blend nodes, but we don't always check for NULL, which leads to
warnings in the CSS Blend modes demo.
Use the same initial check for the accessible object type that we use
when connecting the signal, in case we try to disconnect signals on
different widgets. Additionally, check before accessing data that might
have already been removed.
Fixes: #3403
The accessibility bus might not be available, and if it isn't the case,
it means something has failed at a level where the user can't do much
about it. There's no need to emit a critical warning.
We depend on GObject, which already depends on GLib; on older versions
of Meson, this ends up trying to depend on the system copy of GLib,
instead of the sub-project copy, in case the version of GLib we have
installed is too old.
To avoid bleeding edge deprecations we use GLIB_VERSION_MIN_REQUIRED and
GLIB_VERSION_MAX_ALLOWED. Since we depend on GLib 2.66, we cannot use
API introduced in 2.67, even when conditionally compiled.
- Reorder declaration blocks for code legibility.
- Don't lighten text color on :hover and :selected for better contrast.
- Add missing :focus-visible:focus-within styling to non-:selected row.
- Don't set the sidebar padding twice.
- Add padding to the assistant sidebar directly, as it doesn't have
.navigation-sidebar internally.
- Set missing margin to the sidebar separator.
See https://gitlab.gnome.org/GNOME/gtk/-/issues/3382
If an active grab gets undone on button press (e.g. closing a menu), we
will receive a button release on the new target even though it didn't handle
the button press, and disable ::active state.
This causes warnings when handling the button release, as it tries to undo
::active state that is not really there.
In order to fix this, check that the pointer focus actually had an implicit
grab at the time of receiving the button release, before trying to unset
the ::active state.
If the accessible object is hidden, we can skip the emission of the
AddAccessible and RemoveAccessible signals on the cache, as those
objects won't be visible in the accessibility tree.
Simplify getting the accessible role when checking if an accessible
implementation should present itself; this avoids going through
GtkAccessible twice to get the same data.
The GtkAtSpiContext is responsible for removing itself from the root,
which will remove itself from the cache. Any code path that leads to the
GtkAtSpiContext instance being collected passes through the
unrealization phase, which will also unregister the context from the
accessibility bus and from the cache.
- use the old Industrial style menuitems to make the design feel purposeful
- adjust corners to have compatible border-radii of child elements
- include sidebars and navigation sidebars to look consistent
(plus the assistant sidebar)

The use of volatile was incorrect in GLib and has been that way for
a long time. Recently however that has changed, and this makes GTK
follow suit to avoid using volatile in the type registration.
See also: https://gitlab.gnome.org/GNOME/glib/-/merge_requests/1719
Combined with the above merge request for GLib, this fixes a large
number of compilation warnings when using Clang.
Since GTK4, the functions that used the GtkPackType enumeration,
`gtk_box_pack_{start,end}`, were replaced by `gtk_box_{append,prepend}`,
hence this enumeration isn't used anymore by any function within the
GtkBox type, and the child packing properties were also removed for GTK4.
So this commit adapts the documentation accordingly.
For readonly properties, we show the serialized value
in a label. If we don't take precautions, this can cause
our window to grow extremely wide, and break things.
So, ellipsize things at a reasonable size.
Fixes: #3278
GtkTreeView.get_tooltip_context() takes an inout X and Y coordinates,
but the "out" side is a side effect: the conversion from widget-relative
to bin window-relative coordinates is not documented, and can be done
using public API, if needed.
GtkIconView.get_tooltip_context() follows the same pattern, and takes
two inout arguments for the coordinates, but it does not change them any
more, after GtkIconView's bin window was dropped in commit 8dc5e13e.
There's really no point in having these `inout` arguments, and while
GtkTreeView and GtkIconView are certainly de-emphasised in GTK4, and we
nudge developers to move to the new list views, we should take advantage
of the API break to remove warts.
