If the style changes before we're realized we will delay the
style-updated signal until realize. However, we then lose
the changes bitmap. This means that gtk_widget_real_style_updated()
must treat a NULL change as "everything changed" and queue a resize.
The code was always adding a label widget as a child, but
then skipping over it in forall if a custom_title was present.
This confuses internal logic of GTK+ which assumes that it
can iterate over the entire widget hierarchy with forall,
to maintain state. Fix this by destroying the label when
a custom_title is set, and recreating it as needed.
The function update_window_buttons shows or hides the title header after it
has finished updating the visibility of the various buttons. Unfortunately
this
conflicted with the hiding of the title done when going fullscreen.
This solves the problem and fixes the rendering of fullscreen applications by
using update_window_buttons to control the visibility of the box in the
fullscreen case.
This reverts commit 30a1a79322.
This turns out to be unnecessary when you can set the titlebar
on the window and let GtkWindow handle the events. As a benefit,
we get the window menu on custom titlebars for free.
A new function that sets a custom titlebar on a GtkWindow.
With client-side decorations, the custom titlebar simply
replaces the one that GtkWindow would otherwise create itself.
With traditional decorations, we tell the window manager
to just decorate the window with a border. This works ok
at least with metacity and mutter.
For csd, we were subtracting the border width one too many
times from the child height, causing clipped off content e.g.
in the 'Properties' window in testgtk.
To clear the tooltip one is to set the tooltip to NULL. Though
the GtkEntryAccessible expect this tooltip to not be NULL in
gtk_entry_accessible_notify_gtk (already handling this case
in its _init).
Fixes:
** (epiphany:23914): CRITICAL **: atk_object_set_description: assertion
`description != NULL' failed
when epiphany g_object_set the entry icon tooltip to NULL (clear the
tooltip) in its find bar.

To extract the mnemonic key value, the string must contain the
underscore. But when the "gtk-auto-mnemonics" setting is true and when
the Alt key is not pressed, the underscore must not be displayed. The
problem was that the 'new_str' variable was used for both purposes:
extract the text to display, and extract the accelerator character.
When the underscore must not be visible, the underscores were removed
from the 'new_str' variable before extracting the accelerator character.
Now there are two strings, one for each purpose.

For now, nothing changes, we're using the sum of inner and
outer border everywhere.
In the future, we will make the inner border the visible
window frame, and the outer border the shadow/resize border.
Add a style property to control the presence and order of
window buttons. We allow buttons at the left and right side,
they can be specified like this: icon,close:minimize,maximize.
Also, change the default button layout back to have just a close
button on the right, use icons in buttons, and set style classes
on the buttons, to allow better theming.
Add window-minimize, window-maximize, window-restore and window-delete
icons to the builtin icon theme. These will be used for icons in
the window buttons, and the expectation is that the icon theme
will provide icons matching the desired decoration style.
window-delete is used instead of window-close, since window-close
is also used for GTK_STOCK_CLOSE, and the two may require different
styles when used inside the application vs in the window frame.
Hide the close button if the window is not deletable, hide the
maximize button if the window is not resizable, and hide all
buttons if the window is a dialog.
Update buttons when the window state changes.
Client side decorations can be enabled on non-Wayland platforms by
setting the GTK_CSD="1" environment variable.
We must ensure we have a GdkVisual that has an alpha channel since
the decorations rely on transparency. If we cannot get a visual with
an alpha channel then we do not enable client side decorations.
Otherwise we'll potentially get some background sticking through our rounded
corners in our decorations. The actual background will get drawn as part of
the decoration drawing.
This change comprises four main parts:
* the creation of the widgets that form the decorations,
* implementation of get_preferred_height/width, and the for_width/for_height
variants,
* taking the decorations into account when allocating,
* and drawing the decorations themselves.
Kristian did the bulk of the original work on this but any bugs are almost
certainly mine through the many refactorings and rebasings.
Update the documentation and users of this function to handle
the future case that that we have some internal decorations to the window and
useable allocation is thus smaller.
By having a separate out parameter there is no need to have an in/out function
and allows for greater robustness.
The current implementation simply returns the allocation provided.
For gtk_text_iter_get_char(), due to the "Returns" at the beginning of
the description, the description was not visible. So the first sentence
has been reworded.
If there are rows that contain only spanning children,
our algorithm was unnecessarily distributing extra space
to the other rows, even if they contain only non-expanding
children.
We improve the behaviour by treating rows containing only
spanning children as expanding.
... instead of taking the last one we find. This is necessary as
attached widgets (mostly menus) can be attached to an invisible widget,
but we still want to invalidate styles for them.

When setting new text on the label, the text-changed::delete signal
needs to be emitted before deleting the text (so that atk-bridge can
query the old text) while the text-changed::insert event needs to happen
afterwards (for the same reason). The old code using the notify signal
was only emitted after changing the text.
Both of them started to make use of round(), a C99 function. So, include
fallback-c89.c to provide a fallback implementation for round() for
compilers that don't have round()
