If the async query fails to reproduce a file info,
we still need to thaw the model, otherwise it ends
up frozen forever.
This was deduced by reading the code, I haven't
actually seen it happen.
We can use the new collation property of GtkStringSorter,
and get the benefit of sort key caching. This commit
also fixes an accidental leak of all sorters, and
removes the sorter from the location column - we never
show that column when individual colummns are sortable.
This reverts commit 34752a15a71597d00a8d08befc545ac1c178b81b.
Leaving out the drag source portion as that needs a total
reimplementation. The GtkDropTarget only required minor
modifications.
Put a filter model between the selection model and
the filesystem model, and make it filter on the
filechooser::visible attribute. This makes the filer
combo in the filterchooser and the 'show hidden files'
item work. But we need to prod the filter to trigger
a refiltering every now and then.
Provide the filtered-out and visible bits as a file attributes
under the names filechooser::filtered-out and filechooser::visible,
so that we can filter on it.
To track changes of the selected items in a selection
model, we need to listen to both ::selection-changed
and ::items-changed.
This fixes the open button not turning sensitive
when initially loading a new folder.
When a list item is activated, we activate the default widget.
Unfortunately, due to some other bug, sometimes the open button
is not made sensitive, and then default.activate falls back
to activating the focus widget (which is the item we are just
coming from). Boom
Soon GtkFileSystemModel will not be a GtkTreeModel implementation,
so preemptively remove any usage of this interface. Populate the
list store using the GListModel's 'items-changed' signal.
This has to be the shortest-living object in GTK history!
It helped us greatly during the transition to GtkColumnView, but
now we can remove it in favour of GFileInfo directly. Perhaps I
could have never introduced GtkFileSystemItem in the first place,
but we're 30 commits deep and it's too late to just redo the whole
thing that will get us exactly here anyway.
We now start a mini-series of commits that will ultimately remove
the GtkTreeModel implementation of GtkFileSystemModel.
As a first step, port GtkSearchEngineModel iter through the files
using GListModel API.
Now that most of the treeview usage is gone, remove the remaining
code that uses it - mostly event handling code, which for now won't
work, but will be fixed by next commits - and drop the tree view
entirely.
So far, GtkFileChooserWidget has relied on GtkTreeView's selection
management. This commit moves it away from GtkTreeView, and that's
a massive surgery - sorry :(
The most important aspect of this commit is that 'selection_model'
is now the main model we deal with. Changing between directories,
recent files, and search, all sets the selection_model's model.
Selections are entirely handled by GtkSelectionModel now.
React to column view's 'activate' signal, instead of treeview's
'row-activated'. It doesn't handle file sensitivity yet, but that
will probably be dropped later.
Move the entire location column, which only contains the location
renderer, to the column view. The code to generate locations from
the current folder is essentially intact.
This commit moves the icon loading code into a new private
widget called GtkFileThumbnail, which is bound to the GFileInfo
of the model, and asynchronously loads the file icon from that.
Replace the 'list' page of the main stack with another page, this
one containing a GtkColumnView. This, again, is the very minimal
code to achieve a column view - and validate the GListModel code
introduced in the previous commit - but there's a long way until
this column view covers the full range of features of the file
chooser.
The tree view still lives in an unused 'list2' page. From now on,
commits will "cannibalize" the treeview, each commit porting any
particular feature - be it a column, an event controller, etc -
to the column view, and dropping the corresponding feature from
the treeview.
This is a trivial implementation of the GListModel interface. It
does not do anything fancy, like filtering out hidden files, nor
sorting.
The purpose of this minimal implementation is to bootstrap the
initial work to port GtkFileChooserWidget to GtkColumnView.
On platforms like NixOS, the libX11 installation prefix may differ from /usr/share,
breaking the hardcoded placeholders. Let’s re-use the X11 path definition from imcontextsimple.

Just relying on GAppInfo leads to suboptimal

In overwrite mode, every typed character gets

We can get spurious focus-out/-in pairs when
the editable label is in a popover that gets
a Wayland keyboard enter event as a result of
clicking the editable label.
A timeout isn't a great solution, but nothing
better is available right now.
Fixes: #4864
Only clear a queued move_focus if the widget
we are focusing is actually visible.
This was happening in some cases when popovers
are dismissed by clicking outside, and it was
causing us to miss proper focus updates that
were already queued.
This partially undoes changes from 3dbf5038fa.
That commit did two things:
1) Move the focus update to after-paint time
2) Change from grabbing focus to the visible parent
to calling move_focus (TAB)
The second part did have the unintended consequence
of moving focus laterally.
Fixes: #4903
GtkSingleSelection will only emit either of those signals if they
change. But it is possible that only one of those properties changes,
and in those cases we want to only notify for that property changing in
the dropdown, too.
We don't want to notify::selected or notify::selected-item if they
didn't change.
This will bring performance benefits on frequently changing lists.
In particular, if lists get filtered or reordered, but the selected item
stays in the list, not doing a notify::selected-item will avoid updates
in connected handlers like GtkDropdown (and its handlers), thereby
avoiding lots of unnecessary updates.
There is a widespread need to access the CSS foreground
color for custom drawing in snapshot functions, so make
it available after gtk_style_context_get_color was
deprecated with a new widget api.
The notable exception here are the global provider apis,
which are needed in some form and don't have a replacement
yet. Move them to gtkstyleprovider.[hc], so we can wholly
deprecated gtkstylecontext.[hc].
Move the implementations from gtksnapshot.c to
gtk/deprecated/gtkrender.c and deprecated these
functions. We want to get rid of them.
These functions are still used in some of our widgetry,
so use G_GNUC_BEGIN/END_IGNORE_DEPRECATIONS around
them.
It doesn't require one generally anyway, because only the root can
change scale and when that happens the root will queue a redraw.
But even if the root doesn't queue a redraw, render nodes (the only
thing discarded by queue_draw()) are scale-independant.
The template use in the inspector was not properly
disposing all widgets. gtk_widget_dispose_template
will only unparent widgets that have been named
as template children, so we need to make the toplevel
elements in the ui file named children, or manually
dispose them. This commit does the former.
These are a family of pretty specialized widgets, and
are very rarely used. Instead of porting them away
from GtkTreeView and GtkComboBox, deprecate them.
This reverts commit 11829fe7d0.
The mkenums_simple function can't properly handle headers
in subdirectories currently, so go back to the template
version.
For the same reasoning as the preceding commit.
Also don't make GtkColumnView focusable. Its internal list view
is already focusable, which is enough to take care of the empty
view case.
The container view itself being focusable makes keyboard navigation
slower by adding a useless focus step.
It also means if an item gets removed, the focus jumps back to the view,
instead of jumping to the next item, as seen in nautilus bug report:
https://gitlab.gnome.org/GNOME/nautilus/-/issues/2489
Instead of making the GtkListBase container itself focusable, override
the .grab_focus() vfunc. This way, calling gtk_widget_grab_focus() on
the view container keeps working sucessfully, but focuses the focus
item directly instead.
This is particularly useful to have because applicaiton authors do
not have direct acess to this class's children, so they can't call
gtk_widget_grab_focus() on them directly.
We connect to the inserted-text signal for the entry's buffer.
During the lifetime of the entry, the buffer changes. This is
literally the example used for GSignalGroup in the docs.
MinimumIncrement is an AT-SPI-ism that has no counterpart in the ARIA
specification, so it should not live inside public API. Additionally,
it's not really a useful method because it collapses two values on the
adjustment API.
The only method in the GtkAccessibleRange interface should be the
set_current_value(), which allows ATs to control the current position in
a ranged widget.
The AT-SPI implementation can now use all the accessible properties,
including the VALUE_TEXT one, mapped to the Text property on the
AtSpi.Value interface.
Signal handlers ust return their preferred action and that one must be
unique.
Shout at them if they don't do that, before gdk_drop_status() does
tesame thing.

"left of right" should be "left or right".
There's a small (subjective?) English nit in there as well: I believe
that buttons are placed (for example) "on the right" rather than "at the
right".
Doing reset() on the text widgets after commit and delete_surrounding
is still too eager for some IMs (e.g. those that expect being able
to commit text while keeping a preedit buffer shown).
However, reset() is more of a "synchronize state" action on Wayland,
and it is still desirable to do that after changes that do come from
the IM (e.g. requesting the new surrounding text and cursor/anchor
positions). Notably here, the text_input protocol may still come up
with a preedit string after this state synchronization happens.
Shuffle the code so that the text widgets do not reset() the IM
context after text is deleted or committed, but the Wayland IM does
apply its practical effects after these actions happen. This keeps
the Wayland IM fully up-to-date wrt text widget state, while not
altering the ::commit and ::delete-surrounding-text behavior for
other IM context implementations.

Doing clever things with objcopy is faster and seems to be reliable on

When the IM commands the GtkText to delete text, the cursor position

Update the label size request when setting the digits property
by calling the update_label_request () util function.
That util function works by measuring the size request of the
label with the lower and upper values of the adjustment, then
taking the max. That way the size requisition is constant
regardless of the actual displayed value.
Since the util function internally works by setting the text
of the label, let it also set the text at last by taking in
account the current adjustment's value. Most of its callers
do that anyway.

Do not perform coordinates transformation when gdk_event_get_position()

When reordering notebook tabs, updating the sensitivity state of the
arrow buttons is necessary if the tab is moved to the beginning or

When notebook tabs are reorderable, pressing the notebook arrow buttons to

Claim the event sequence after pressing an arrow button to avoid conflicts
with the motion/drag gesture used for reordering.
A typo resulted in the tab container widget being retrieved instead of
the tab widget. If an adjacent action widget was present, an infinite

Currently, the wayland IM context sends zwp_text_input_v3.commit from
a number of places, and some of them with partial data. In order to
make client state updates "atomic" and complete, make the communication
happen over an unified notify_im_change() function that happens on
a narrower set of circumstances:
- The GtkIMContext is reset
- The GtkIMContext is just focused
- The gesture to invoke the OSK is triggered
- The IM context is reacting to changes coming from the compositor
Notably, setting the cursor location or the surrounding text do not try
to commit state on their own, and now will be flushed with the corresponding
IM update or reset. But also, these requests won't be prevented from
happening individually on serial mismatch, instead it will be the whole
state commit which is held off.
With these changes in place, all client-side updates are notified
atomically to the compositor under a single .commit request.

c68247f63b introduced a scroll multiplier,
intended to be significantly lower than the GTK 4.6 behavior but higher
than 1. However, it was _higher_ than 4.6, since 4.6 also had a permanent
1/10 multiplier in GDK, so the cited multiplier values were really 6.4 and
9.7.
We may have situations where velocity is 0/0, but are overshooting. Places where
this happens are mouse wheels, and continuous scroll that ended up still before
finish. In this situation we also want to run the animation for overshoot, so
check for the corresponding axes to also set up the kinetic scroll helper.

The expected configurability is not going to arrive yet from compositors, and
it is precipitate for GTK to gain any configurability. We do know a factor of 1
feels way too slow, and we do know a factor of page_size * pow (2 / 3) feels way
way too fast.
With the previous multiplier, gtk4-demo at its default size had a vertical textview
factor of 64.332901, and maximized on a 1920x1080 screen a factor of 97.585365.
Pick a magic multiplier that is both significantly below these values and above 1,
and stick to it.
Future work will add the configurability of smooth scroll events where it belongs.
At that point this commit may be reverted so we don't pile up on magic numbers again.

Following what was done for pinch/swipe events, give hold gestures their
own distinct sequence as well. Without this it was NULL, which was already
distinct to other touchpad gestures.
This delaying of the cancel event was made to avoid intermediate cancellation
for >=2fg hold gestures followed by pinch/swipe gestures, and it worked as
long as everything was considered to have the same sequence.
Since each pinch/swipe pointer gesture now gets its own sequence, this no
longer applies, nor works. This results in zoom/rotate/swipe gestures being
stuck since the sequence for the touchpad events changes mid-gesture.
Sticking to this pattern of giving touchpad gestures their own sequence,
these hold events cannot be assumed to coalesce with other touchpad gestures,
it is better to let it propagate altogether so that both the hold gesture
and the incoming gesture trigger coherent begin and end/cancel phases.
In the worst case, this results in "::begin, ::cancel, ::begin , ..." before
triggering a touchpad gesture, but the extra begin/cancel ought to be a safe
no-op in widgets.
