Pour joindre un élément graphique enfant à l'emplacement gauche, superieur dans un créneaux de taille largeur, hauteur donné, utilisez la méthode attach(enfant, superieur, gauche, largeur, hauteur). S'il y a déjà un élément graphique sibling à cette place, utilisez la fonction attach_next_to(enfant, sibling, side, largeur, hauteur), où side est l'une des positions Gtk.PositionType.LEFT, Gtk.PositionType.RIGHT, Gtk.PositionType.TOP, Gtk.PositionType.BOTTOM.
insert_row(position) and insert_column(position) do exactly what they say; children which are attached at or below this position are moved one row down, and children which span across this position are grown to span the new row. insert_next_to(sibling, side) inserts a row or column at the specified position. The new row or column is placed next to sibling, on the side determined by side; if side is Gtk.PositionType.TOP or Gtk.PositionType.BOTTOM, a row is inserted, if side is Gtk.PositionType.LEFT or Gtk.PositionType.RIGHT, a column is inserted.
Les méthodes set_row_homogeneous(True) et set_column_homogeneous(True) vérifient que chaque ligne ou chaque colonne a la même largeur ou la même hauteur.
set_row_spacing(spacing) and set_column_spacing(spacing) force a spacing between (respectively) rows or columns. The value of spacing can be between 0, which is the default value, and 32767.
Dans cet exemple, les éléments suivants sont utilisés :
GtkApplication
GtkApplicationWindow
GtkLabel
GtkImage
