Description
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
pack1() and
pack2() . 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.
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 set_position() .
