GtkPaned
is the base class for widgets with two panes,
arranged either horizontally (GtkHPaned
) or
vertically (GtkVPaned
). Child widgets are
added to the panes of the widget with
gtkPanedPack1
and gtkPanedPack2
. The division
beween the two children is set by default from the
size requests of the children, but it can be adjusted
by the user. A paned widget draws a separator between the two
child widgets and a small handle that the user
can drag to adjust the division. It does not
draw any relief around the children or around
the separator. (The space in which the separator
is called the gutter.) Often, it is useful
to put each child inside a GtkFrame
with the
shadow type set to GTK_SHADOW_IN
so that the
gutter appears as a ridge. No separator is drawn
if one of the children is missing. Each child has two options that can be set,
resize
and shrink
. If resize
is true, then when the
GtkPaned
is resized, that child will expand
or shrink along with the paned widget. If shrink
is true, then when that child can be made smaller
than its requisition by the user. Setting shrink
to FALSE
allows the application to set a minimum
size. If resize
is false for both children, then
this is treated as if resize
is true for both
children. The application can set the position of the slider
as if it were set by the user, by calling
gtkPanedSetPosition
. Creating a paned widget with minimum sizes.
