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.
