Added GtkTreeMenu class to automatically render
a GtkTreeModel into a GtkMenu hierarchy (will be
used by GtkComboBox for its dropdown menus). Included
an accompanying testcase tests/testtreemenu
The 'Properties' button here is not really modifying the property
in any way, so it doesn't make sense to disable it just because
the object can only be set at construction.
This lets us poke at e.g. the cell area of an icon view.
This commit does a number of things:
- remove some dead wchar configury from configure.ac and gdkconfig.h
- repurpose gdkconfig.h as header that contains GDK_WINDOWING_foo
macros for each included backend, include it in gdk.h and install
it in $includedir instead of below $libdir
- drop the backend from the library names
- build libgdk-3.0.la as a convenience lib and include it in libgtk-3.0.la
It does not yet enable building multiple backends at the same time.
Now a cell can either have a "fixed" size or it can have
an "aligned" starting point or both. "fixed" size cells take
no space when they are invisible.
This argument allows the caller to specify that only an editable
cell should start editing but an activatable cell should not toggle
it's state, this is important for public apis like
gtk_tree_view_set_cursor_on_cell() which are only intended to
programatically bring attention to the editing of a specific
row or cell but not actually change any data.
GtkTreeView & CellAreaScaffold updated for the last minute api change.
Some details:
- button_request was not needed, consult the minimum request of the button
- gtk_tree_view_column_get_button() needed to be public as people can set
tooltips on the button (and libgail accesses the button).
It's a better test case if the scaffolding only displays the rows from top
to bottom and doesnt line up the cells from left to right (because it shows
that height-for-width still works with vertically oriented areas).
- When we reach a cell that is out of the render area, break out
of the loop (for columns user resized too small)
- CLAMP the size of the last renderer to fit into the area
(so that renderers get a chance to ellipsize when rendered
with a space less than allocation, same reason as above).
- Hand out remaining space in the render area to the last cell,
this is for shallow rows in the expand column which may recieve
more than the allocated width.
Introduce a 'custom-item-activated' on the widget, which behaves
similairly to GtkEntryCompletion::action-activated, i.e. is emitted when
a custom item is chosen from the dropdown list.
Clients can use the name provided when adding the item as a detail for
the signal, to get notified when that specific item is activated, or use
the signal without details to get notifications for all custom items.
The GtkSwitch widget is a simple UI control that has two states: on and
off. Toggling between the states is possible by clicking the widget or
by dragging the handle.

Turns out theres not much reason to do this in a separate api,
now we just sum up the sizes of aligned cell groups in GtkCellAreaContextBox
when pushing the group size.
This commit adjusts the app chooser code to GTK+ coding style:
- line up prototypes
- remove some excess {}
- remove tabs and trailing whitespace
- add docs
It is really bad code, mostly unused and no one stepped up to fix it.
Note that Gtk developers do not object to a ruler widget in priciple,
just to the current implementation. If someone wants to propose a sane
version, please don't hesitate.

Like GtkFileChooser does; GtkOpenWith is a generic interface, which is
now implemented by both GtkOpenWithDialog and GtkOpenWithWidget (and in
the future also by GtkOpenWithComboBox).
CellAreaScaffold now also reflects how cell_area should be
passed to gtk_cell_area_activate() and gtk_cell_area_event()
and how the background area for gtk_cell_area_renderer() should
be created.
- Added gtk_cell_area_aligned_cell_area() to get the aligned
internal area use by a cell (for focus painting and for
event areas).
- Provide the event area in "editing-started" signal
- Fire "remove-editable" when editing is canceled by the user,
an implementing layouting widget need only catch "editing-started"
and "remove-editable" now.
- CellAreaScaffold/testcellarea now edit textrenderers.
Now GtkCellAreaBox handles the click event to activate renderers
and checks if the area is in a sibling of a focus renderer, possibly
activating the proper focus sibling renderer.
Also GtkCellArea gains a "focus-changed" signal to allow it to
change the currently focused row according to the button events.
