We should have a single job for building both static and shared
versions of GTK. On the other hand, having a separate job for the
release build would be a plus.
Additionally, we shouldn't use an opaque script to build GTK; the only
step in the process that requires hand-holding is running the tests
suites under Xvfb, and having the build options visible from the YAML
file gives us a better idea of what kind of build we're running.
As pointed out in https://gitlab.gnome.org/GNOME/gtk/issues/1481
and seen from critical warnings with swinging revealers in widget-factory
there are some size allocation issues in GtkRevealer.
What happens is that we request a size of the revealer itself
based on the child natural size and the current stage of the transition
by applying a scale to the natural size. We then round up to nearest
int size. However, we want the widget to render as if it did get the
natural size so we can transform it, rather than the scaled down size.
For example, a label should not start ellipsizing in the animation.
So we inverse the scale when allocating the child.
Unfortunately, for very small scales the inversion of the scale can
result in very large sizes, and for such scales we rounded up the
requested size to 1, so we will be allocating huuuuge children.
In order to avoid such issue we pick an arbitrary maximum upscale
scale factor of 100. This means that in the case where the allocated
size is 1 we never allocate the child at > 100 px. This means
that in large downscaling cases we may run into the clipping issue
described above. However, at these downscaling levels (100 times!)
we're unlikely to notice much detail anyway.
I was getting assertions that normalize_angle() failed the
result < 260 check. Doing some research on this it turns out
to be a precision issue. If the incomming angle is very slightly
below zero, then adding 360 to it may end up with exactly 360.
I simplified the code a bit to avoid division and rounding, because in
practice most angles will be "just outside" the 0-360 degree anyway.
And i also added a workaround for the "result is 360" case by just
setting it to 0.
When rendering ops to an offscreen texture we take max-texture-size
in consideration and modify the scale we use such that the required
texture does not exceed the limit.
This means some rendering will be blocky/fuzzy, but that is better
than it being clipped.
We can't just use the outline rect and apply the border radius because
the outline box is the border box grown by the outline offset, which
will also grow the resulting border radius.
Fixes#2425
This tests was testing gestures by faking an event in the
middle of a window that has a hbox with an expanding image in it.
For me (and I guess this depends on all sorts of issues like whether
CSD is enabled, font sizes, etc) the hbox ended up centered horizontally
but not vertically (probably because of csd at the top), so no events
ever hit the inner widgets.
This is fixed by emitting the events at allocation.x/y of the
hbox, which should contain both the hbox and the image (as it expands).
All the code in e.g. init_randr15() divides the physical resolutions with
the screen scale, however if we get the screen scale from xsettings
rather than e.g. GDK_SCALE the initial setup is using the wrong value.
So, whenever the screen scale size is changed we need to trigger
a re-read of the randr data
We test this by looking at the produced render nodes now that
we don't actualluy scale the icon. Also, it turns out that this
code was broken due to some typos, so we also fix those.
If you called gtk_icon_theme_lookup(), then always return some useful
icon name from gtk_icon_paintable_get_icon_name(), even if we picked
an unthemed icon.
Also rewrite the gtk_icon_paintable_get_icon_name() docs to make this
clearer.
