Status of the GTK+ 2.0 port :

---------------------------

Remaining problems :

GtkList and GtkCList ==> GtkTreeView conversion :
|
|
- main.c :
|
|
|
|
- gtk_font_selection_dialog_set_filter doesn't exist anymore (but hasn't
|
|
been removed from the documentation). There is no way to filter the
|
|
font selection to get only fixed width fonts; in a message at

Owen Taylor explains why Pango (and hence GTK+ 2.0) doesn't know what
|
|
fonts are fixed-width and what fonts aren't:

|
|
|
|
Give us code that can distinguish reliably between monospaced and
|
|
not-monospaced fonts for Type1 and TrueType fonts and at that
|
|
point it becomes reasonable to think about such an API. It's
|
|
not all that easy to do.
|
|
|
|
Even then, there are still problems - Pango by default will
|
|
draw characters not in the main font using fallback fonts --
|
|
whose metrics almost certainly don't match your grid. So,
|
|
you'd have to be able to turn this off.
|
|
|
|
- the spacing between lines in the tree view is too big ;
|
|
|
|
- gdk_font_from_description() may return NULL. It would be better to use
|
|
pango and drop GdkFont (and functions which use it, like
|
|
gdk_string_width, gdk_draw_string).
