|
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
|
|
gtk_paned_pack1() and gtk_paned_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.
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
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 it's 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.
|
|
</para>
|
|
<para>
|
|
The application can set the position of the slider
|
|
as if it were set by the user, by calling
|
|
gtk_paned_set_position().
