We were trying to avoid selecting a label initially, but the code
was sometimes leaving labels selected when the focus eventually
ended up on a button instead.
Seems commit 7b42d4feda makes
GtkSpinner a direct subclass of GtkWidget but forgets to
update the header file to include gtkwidget.h instead and
declare the instance and class structures properly (assuming
this was just a missed file in the commit).
Originally the GtkSizeRequestIface patches left GtkSizeGroup working
only by bumping the minimum sizes - this commit fixes size groups to take
both minimum and natural requests into account.
Since the location button is hidden in save mode, we need to add the
path bar to the size group too. The location button still has to be in
the group though, because it's larger than the path bar (when
shown). Instead of using the recent/search icons, add their hboxes so
that themed widget spacings don't introduce variations.
With this new approach at request and allocate time, the average child size
is used to determine a good guess at how many columns will fit the box
width; afterwards extra columns are appended and checked to fit.
Then the row heights are calculated based on height-for-width of each
child in the row which now may have individual widths.
The detail strings now have more "detail" by default, so gtkstyle.c
needed to be updated to properly handle this. Tests like testtreeview,
testtreesort now have proper background drawing again.
This strncmp trick was the best I could think of so quickly, if anybody
has an idea to do this in a better way, let me know.
h-align = START,END,CENTER,FILL
v-align = START,END,CENTER,FILL
margin-left,right,top,bottom
margin
These should obsolete all such similar properties on
layout containers, GtkMisc, GtkAlignment, GtkContainer::border-width
Margin is outside the size request.
If margin were not outside the set_size_request() it would not work the
same way as container-supplied (child property) padding.
Conceptually set_size_request() forces the value from the subclass
(the original unadjusted request) and then we go on to adjust
the request further by adding the margin.
A subclass calls gtk_container_class_handle_border_width()
in its class_init
This marks the subclass as expecting GtkContainer to deal with
border width automatically, which GtkContainer then does.
Use these new methods to handle set_size_request (aka aux_info)
inside gtkwidget.c, instead of having external code mess with it.
The virtual functions can be used for other purposes in the
future. For example, GtkContainer::border_width could be
automatically implemented for all container subclasses.
Did not update uses in other files because the plan is to
get rid of those other uses anyhow. So don't want to make
this function available in the header.
This is better than peeking aux info then testing != NULL
in several ways:
- it returns const aux info so if we don't create we can't write
- it ensures that the default we assume if aux_info is NULL is
the same as the default we set if we've created the aux info
- it avoids typing in != NULL checks
