show_or_hide_handles() tries to disable visibility when the popover is
shown, although it triggers a bit late, and lets the handles flash briefly
if both popover and handles try to show at the same time (eg. when
pressing on the selection of a previously unfocused textview, the handles
were previously hidden, so they try to show again on focus in).
The handles might fall outside the visible area, and shouldn't be shown
then. Just call gtk_text_view_update_handles() which will perform these
checks, and keep the handle conveniently hidden.
This was leading to unexpectedly visible handles (and in the
wrong/previous position, the handle code doesn't relocate the widget
it's about to hide) when "select all" was selected in the popover on
a textview needing scrollbars.
and extending the selection beyond the view above and/or below.
The buttons on the popover where stealing the focus from the text
view on click, causing the popover to be dismissed before the action
was taken. Fix this by making the buttons not take focus on click.
Use the drag-started signal to differentiate between drags that
move a handle and taps on a handle. Show the touch selection popup
for the latter, but not the former.
Hide the handles when the popover appears, and brind them back
when it disappears. This will need revisiting if we start using
the popover for mouse interaction as well, where we may not
want handles to show up.
We don't want the popover to appear spontaneously, so eventually
the timeout may go away altogether. For now, shorten it to 50ms,
to avoid rewriting all the places where the timeout is set or
unset.
Update style for touch selection in GtkEntry and GtkTextView
according to https://wiki.gnome.org/Design/OS/Selections
Add 'Select All' to the default actions, change actions
to use icons and move the popover to the bottom. If there is
no selection, just offer to paste.
Text insertion/pasting might trigger scroll, so we'd have to wait
until the text was revalidated and the scrolling truly happened
before we can check the new handle(s) position.
Just use the last coordinates given on XdndPosition/drag_motion() in
order to trigger scrolling.
When running on Xwayland, the pointer position is unknown at this
stage on the X11 side, so the coordinates given here are bogus.
This change avoids both roundtrips and this situation.

The magnifier is now set enough height to show the line being currently
manipulated, which makes it just big enough to show the layout height at
that size and magnification.
- It is not possible anymore to trigger text DnD through touch, pressing
and dragging from within the selection will instead extend it. Text
shrinking is still available through the handles
- The selection mode for touch is per-word, char-level manipulation is
still available through the handles.
- Tapping within the selection will bring in text handles, and toggle
text selection popover.
This mode could also shrink the selection, plus the starting point would
seem somewhat arbitrary (actually dependent on the dragging direction of
the last selection).
Made this mode more consistent by only allowing it to extend the selection,
only in one direction for each operation, and so it keeps the current
selection as a minimum.
Instead of passing a GdkEvent and let the function figure out whether the
selection should be extended, let that to the caller and just pass a
boolean here.
This is a convenient shortcut for a common case. It is implemented
by adding a .monospace style class to the text view, and letting
the theme decide about the monospace font to use.
- gtk_style_context_get_background_color()
- gtk_style_context_get_border_color()
Those functions shouldn't be used anymore, because they don't represent
anything from the CSS styling we support. The background color often
isn't used due to background images and there are actually 4 different
border colors (1 for each side) - if there isn't also a border image in
use.
Try to tidy up how the background is set on the textview:
*) the .view class should be applied only to the text window, not
to the margins
*) when setting the background on the margins we must use .left etc
*) use context_set_bg instead of manually setting the color

The timeout ID used to be unset after we got the targets from the
clipboard, but there's still a moment between the clipboard request and
the GDK_SELECTION_NOTIFY event that the ID points to an already gone
timeout.
That gesture is meant to handle clicks on multiple buttons, so unset
the GDK_BUTTON_PRIMARY default. Also, remove unnecessary boilerplate
with the new GtkGestureSingle/GtkEventController defaults.

An animation may be scheduled while the textview content changed in size, so the resize
queued would just unset the animation and set the adjusments with a current value,
defeating gtk_text_view_scroll_to_iter(). In this case, just avoid the adjustment change,
as there is a target value on the way.

This allows subclasses to render things below and above the text
in the text view. This allows e.g. GtkSourceView to highlight the
cursor row and to render overlays for colum 80. This used to be done
by rendering before/after chaining up to the parent, but that doesn't
work anymore since the view now renders a background, and due to the
use of the pixel cache.
This reverts commit 1ac13435b7.
We want to instead replace this with special vfunc for drawing
below/above the main text so that gtksourceview can use it.
There was this hack, taken verbatim from GtkCList according to the comment,
that would recursively translate the allocation during scrolling, and set
it on children widgets through the direct gtk_widget_set_allocation() setter.
Since commit 4f89eb05cf, this has caused the wrong clipping areas to children
widgets of a textview. The reasons for this seem lost in time, and the approach
seems indeed wrong for windowed widgets as the repositioning of those windows
couldn't happen.
So replace all of this with just a gtk_widget_size_allocate() call, which does
work ok for the children widgets embedded in the "multiple views" gtk demo, and
ought to work for every other widget.

Use the adjustment target value when repositioning the cursor, and remove the
checks that ensured the cursor was made onscreen immediately, as there will
be definitely a delay on animated adjustment changes.
