- Removed most of GtkCellLayout implementation in favor of ->get_area()
- This allows GtkBuildable cell layout implementation to implement
the child "cell-properties"
- Also allows feeding a custom/different GtkCellArea implementation to
layout cells.
- Share the internal area with the created GtkTreeViewColumn.
Now consult gtk_cell_area_context_get_preferred_height().
It can be that height-for-widths requested here were too large
when multiple cells are in play because of the alignments stored
in the context... removing the temporary focus-line-width hack.
Allow feeding treeviewcolumn a custom cell-area (or not a custom one,
but allow sharing the cell-area with say, the combo-box area).
This patch also:
- Fixes signal connections to the area (now they do eventually get
disconnected at dispose time, they are handled regardless if a
treeview is set but execute safely, at least there is only one
connection/disconnection).
- Fixes refcounting on the cell_area (GtkCellArea is GInitiallyUnowned).
- Adds a constructor() in order to build the cell-area if one has
not been provided by the caller before hand at g_object_new()
construct time.
This fix has evolved in the staging branch since all column members are
on a private structure, but since it causes warnings when closing the
windows of the testcellarea test (because the combo-boxes use a treeviewcolumn)
I thought it nice for now to just manually include the fix.
The fix is just proper bookkeeping of delegate objects at dispose() time.
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.
If the area has no activatable cells and has focus when
focus should be cycled, immediately focus out of the area
(because focus in that case is given to the entire area).
Thomas Wood pointed out that the original MxGtkLightSwitch widget upon
which I based the behaviour of GtkSwitch was not written by him; the
original authors are:
Joshua Lock
Robert Staudinger
Jussi Kukkonen
My apologies to all of them.
Based on a patch by Matthias, add an "active-id" property for
GtkComboBox and add some convenience API for GtkComboBoxText.
Also, add a test case to gtk-demo.
ATK provides macros to the same effect as G_DEFINE_TYPE; using these
macros has the advantage of removing tons of duplicated code and
reducing the maintainership burden.
The widgets with inline accessibility implementation should switch to
these macros, and clean up the code.
