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.
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).
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.
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.
