Your question is not quite clear to me. It seems to be about two issues: 1. auto-resizing of labels, 2, what containers to use for your layout. Regarding GtkLabels: automatic resizing is their default behaviour, regardless of which sort of container (Gtktable, GtkVBox, etc.) it is being put into. Example: when working with Glade, just create an empty dialog window. Drop a new GtkLabel into it (directly into the window, without additional layout containers). Make the window as small as possible (not via the "minimizie" button). You will see that you can't make the window smaller than the dimensions needed by the GtkLabel to have its text (should be "label1" or similar) fully visible. In Glade's "properties" window, when you type in additional text into the "Label" property of the GtkLabel, you can see the window grow as you type. Again, this is the default behaviour of GtkLabel (and most other types of widgets as well) and is not bound to particular containers like GtkTables or Boxes. However, if your texts may get "really long", this behaviour shouldn't actually be what you want. Especially if the label has disabled its wrapping property, restricting the label text to just one line, the horizontal size requirement by the label may easily exceed the screen's dimensions, making the window wider than the screen as well. This would make your application basically useless. There are three common strategies to consider if you're planning to deal with display of really long texts. They aim at avoiding unrestricted size requests by the GtkLabel: 1. enable the "wrap text" property of the GtkLabel 2. put the GtkLabel into a GtkScrolledWindow 3. use GtkTextView instead of GtkLabel, with "editable" property unset. Regarding the other aspect of your question: what layout containers to use and the extent of complexity is determined solely by what layout you actually want to achieve. For instance, having 20 rows with each one consisting of a GtkButton and a GtkLabel next to it, and all widgets aligned vertically, is quite a simple layout. You would only need one GtkTable with 2 columns and 20 rows for it. You could also easily use 10 rows with 4 columns (button, label, button, label) each with the same single table. More complex layouts require additional layout containers, of course. You didn't provide any idea what sort of complex layout hierarchy you want to achieve so I can't give more detailed recommendations. _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
