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.
