Since gtk_table_attach() is
somewhat cumbersome, there's a simpler version called
gtk_table_attach_defaults(),
shown in Figure 18.
This version attaches the child with the options GTK_EXPAND and GTK_FILL, and no padding.
It's tempting to use
gtk_table_attach_defaults() all the time to save
typing, but really you shouldn't; in fact, it's
probably fair to say that it's rarely used. The
function is only useful if the defaults happen to be
exactly the settings you want. Most of the time, you
need to carefully tweak your table attachment
parameters to get really nice behavior when your window
is resized. Always try resizing your window to be sure
you've designed your layout well.
