In Xfce-4.6 wird versucht in Dialog-Fenster, Abstände einzubauen. Das neue (4.6)-Einstellungs-Dialog benutzt diese Werte größten Teils einwandfrei.

• Toplevel GtkContainer::border-width = 6
• Notebook tab GtkContainer::border-width = 12
• GtkVBox::spacing = 6
• GtkHBox::spacing = 12
• Internal GtkBox::border-width = 6
• GtkButtonBox::spacing = 12 (Ich bin hierzu nicht sicher!)

• GtkTable::border-width = 0
• GtkTable::column-spacing = 12
• GtkTable::row-spacing = 6

• Indentation: use GtkAlignment, set:
  • padding-top = 0
  • padding-bottom = 6
  • padding-left = 12
  • padding-right = 0
  • border-width = 0
• For situations where the GtkAlignment is the first child of a GtkFrame, having no top padding looks a bit weird. In those cases, I set border-width to 6, padding-bottom to 0, and padding-left to 6. Should probably just use padding-top = 6, though, to avoid extra padding on the right.
