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.
Added concept of "Focus Siblings" to GtkCellArea so that some
static text/icon may be included in the focus/click area of
an activatable or editable cell, implemented focus drawing
as well, updated testcellarea to reflect the changes.
- Fixed focus driving in GtkCellArea with refined apis
- Added gtk_cell_area_activate() to be called when the area has focus
(to activate or start editing the focused cell)
- Added support for this in cellareascaffold
- testcellarea now watches the "toggled" signal for a toggle renderer
and updates the model state accordingly, this currently works with
keyboard navigation, however focus is still not painted on cells.
This patch adds the GtkScrollablePolicy type property to GtkScrollable
and implements it in all subclasses. GtkScrolledWindow observes this
property to make a good guess about when to show/hide scrollbars for
height-for-width content.
Most scrollable children do not do height-for-width *yet* but
most certainly will (toolpalette, treeview, iconview, textview
widgets all TODO), for scrollable widgets that do have a minimum
and natural size, it's important for them to observe the state
of this property in order to properly drive the scroll adjustments
according to the desired GtkScrollablePolicy. This patch makes
GtkViewport do this.
Patch also adds tests/testscrolledwindow.c to display the effects
of this property.
alignment/margin vfuncs adjust_size_request/allocation
Now get_height_for_width() will internally update the for_width
before passing it to the real height_for_width() vfunc, allowing
margins and extra space for alignments to be stripped, thus requesting
sufficient height for greater than natural widths (and also accounting
for margins properly). Test case adjusted in testadjustsize to ensure
proper behavior.
