GtkWindow has a focus_widget that points to the current input focus.
GtkWidget has a focus_child that points to the child that contains
the input focus. Following the focus_child chain from the toplevel
always leads to the focus_widget. We never unset focus_child, we only
set it. We bubble focus change events.
Make the function that determines initial visibility
look at whether the class implements GtkRoot. That is
the eventual goal for this check. For now, allow
popovers in here as well.
It can be a bit confusing to have an indicator
and an action next to each other, and with the
peek icon, the need for the Caps Lock warning is
reduced, since you can just reveal the text to
see that it is capitalized.
Therefore, only show the Caps Lock warning if
the peek icon is disabled.
Add a ::show-peek-icon property and show a clickable
icon when it is set. Clicking it toggles the visibility
of the content. The same functionality is also accessible
via a context menu item.
This is a common feature of password entries.
We don't want it to appear clickable, but we still
need to keep it pickable for the tooltip to work,
so explicitly give it the same cursor that we use
for the text.
Make the API expect a tranform of the proper category instead of
doing the check ourselves and returning TRUE/FALSE.
The benefit is that the mai use case is switch (transform->category)
statements and in those we know the category and don't need to check
TRUE/FALSE.
Using the wrong matrix will now cause a g_warning().
In case the theme doesn't set a height/min-height for the treeview
separator the treeview drawing gets confused and draws rows on top of each
other depending on the redraw area.
This is due to gtk_tree_view_get_row_height() assuming that a node with a
height <= 0 is not set and not a separator and it will default to the
expander size.
Ideally gtk_tree_view_get_row_height() would know if it operates on a separator,
but there are too many calls/levels, so just make sure the separator height
is at least 1 (Adwaita already sets "min-height: 2px", so no change there)
Cherry-picked from !614 to master
Picking is done by drawing a line along the parent's z axis and picking
at the intersection with the child's z=0 plane.
However, the previous code was casting a ray along the child's z axis.
This patch actually transforms the line to pick into the target's
coordinate system and then computes the corrrect intersection with the
z=0 plane.
Using graphene_point3d_interpolate() to compute the final intersection
point is a bit of abuse of that function, but I found no better way in
Graphene to achieve the same thing.
