Seems the redraw was not happenning from keynav when set_focus_cell()
was called because keynav already updates the focus-cell. Now we
just unconditionally redraw the focus item when set_focus_cell() is
called.
Icon View was not initially setting focus on a cell when
focus initially comes into the view. Focusing into whatever
is the first cell in the cursor item when set_cursor_item
is called with a NULL cell fixes this.
GtkIconView sets the minimum width of the text cell to be at least 50
pixels and otherwise twice the width of the first pixbuf cell found
in the icon list.
GtkIconView should have a "grow-only" mode to handle optimization to
only allow icons to grow in width when rows change, however since
GtkIconView still does not handle large numbers of rows for now we'll
just relayout the whole thing whenever a series of rows change.
Also fixed up to watch the context incase of implicit resets.
of each row.
GtkIconView now properly calculates the height of each row separately
using a separate GtkCellAreaContext stored in an array which it can
always easily index with the item->row index for all purposes.
However, I'm going to have to figure a way to store the alignments
for rows separately, this may involve using a separate GtkCellAreaContext
for each row, unfortunately.
Some things still not sorted out, GtkCellAreaContext is not allocated
so icons dont recieve alignments yet, focus navigation is not exactly
what it used to be (maybe we can work around that by observing the
item orientation and explicitly setting focus to the same cell when
navigating in the wrong orientation).
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.
It is just too annoying to have to implement these properties in
every scrollable. Instead, we now have ::min-content-height/width
in GtkScrolledWindow.
We also add GtkScrollablePolicy to determine how to size the
scrollable content.
The GtkScrollable interface provides "hadjustment" and "vadjustment"
properties that are used by GtkScrolledWindow. It replaces
the ::set_scroll_adjustment signal. The scrollable interface
also has ::min-display-width/height properties that can be
used to control the minimally visible part inside a scrolled window.
Remove the check for GTK_TREE_MODEL_LIST_ONLY and make the view
display only the first level of the tree, ignoring all insert, remove
etc. events on the model's branches. This enables generic application
code which always produces GtkTreeStores (also for flat lists) to
display grids of these flat trees.
gtk_icon_view_layout(), which can resize the bin window and thus
underlying surfaces, could be called from gtk_icon_view_draw(). So
we have to make sure that layouting is done before the draw handler is
called. We use the same construction as in tree view here, the layout
idle handler is installed with a higher priority than
GDK_PRIORITY_REDRAW and we wrap the call to gdk_window_process_updates()
in a new function that will flush the layout queue beforehand.
This mostly goes to keep consistency with the changes to GtkSizeRequest
in the last patch, as GtkCellSizeRequest requires GtkCellRenderer and
GtkCellRenderer implements GtkCellSizeRequest there's no use in keeping
them separate.
This patch renames the functions:
gtk_cell_size_request_get_request_mode()
=> gtk_cell_renderer_get_request_mode()
gtk_cell_size_request_get_width()
=> gtk_cell_renderer_get_preferred_width()
gtk_cell_size_request_get_height()
=> gtk_cell_renderer_get_preferred_height()
gtk_cell_size_request_get_size()
=> gtk_cell_renderer_get_preferred_size()
gtk_cell_size_request_get_width_for_height()
=> gtk_cell_renderer_get_preferred_width_for_height()
gtk_cell_size_request_get_height_for_width()
=> gtk_cell_renderer_get_preferred_height_for_width()
... and moves the corresponding vfuncs to GtkCellRenderer.
The patch also renames the implementations of these functions in cell
renderers to include the word "preferrred".
It doesn't make sense to keep them separate as GtkSizeRequest requires a
GtkWidget and GtkWidget implements GtkSizeRequest, so you can never have
one without the other.
It also makes the code a lot easier because no casts are required when
calling functions.
Also, the names would translate to gtk_widget_get_width() and people
agreed that this would be a too generic name, so a "preferred" was added
to the names.
So this patch moves the functions:
gtk_size_request_get_request_mode() => gtk_widget_get_request_mode()
gtk_size_request_get_width() => gtk_widget_get_preferred_width()
gtk_size_request_get_height() => gtk_widget_get_preferred_height()
gtk_size_request_get_size() => gtk_widget_get_preferred_size()
gtk_size_request_get_width_for_height() =>
gtk_widget_get_preferred_width_for_height()
gtk_size_request_get_height_for_width() =>
gtk_widget_get_preferred_height_for_width()
... and moves the corresponding vfuncs to the GtkWidgetClass.
The patch also renames the implementations of the vfuncs in widgets to
include the word "preferrred".
