GtkPaned has two panes, arranged either horizontally or vertically. The division between the two panes is adjustable by the user by dragging a handle.
Child widgets are
added to the panes of the widget with gtk_paned_pack1()
and
gtk_paned_pack2()
. The division between 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
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 gtk_paned_set_position()
.

GtkPaned has a main CSS node with name paned, and a subnode for the separator with name separator. The subnode gets a .wide style class when the paned is supposed to be wide.
In horizontal orientation, the nodes of the children are always arranged from left to right. So :first-child will always select the leftmost child, regardless of text direction.

GtkWidget *
gtk_paned_new (GtkOrientation orientation
);
Creates a new GtkPaned widget.
Since: 3.0
void gtk_paned_add1 (GtkPaned *paned
,GtkWidget *child
);
Adds a child to the top or left pane with default parameters. This is
equivalent to
gtk_paned_pack1 (paned, child, FALSE, TRUE)
.
void gtk_paned_add2 (GtkPaned *paned
,GtkWidget *child
);
Adds a child to the bottom or right pane with default parameters. This
is equivalent to
gtk_paned_pack2 (paned, child, TRUE, TRUE)
.
void gtk_paned_pack1 (GtkPaned *paned
,GtkWidget *child
,gboolean resize
,gboolean shrink
);
Adds a child to the top or left pane.
void gtk_paned_pack2 (GtkPaned *paned
,GtkWidget *child
,gboolean resize
,gboolean shrink
);
Adds a child to the bottom or right pane.
GtkWidget *
gtk_paned_get_child1 (GtkPaned *paned
);
Obtains the first child of the paned widget.
Since: 2.4
GtkWidget *
gtk_paned_get_child2 (GtkPaned *paned
);
Obtains the second child of the paned widget.
Since: 2.4
void gtk_paned_set_position (GtkPaned *paned
,gint position
);
Sets the position of the divider between the two panes.
paned |
a GtkPaned widget |
|
position |
pixel position of divider, a negative value means that the position is unset. |
gint
gtk_paned_get_position (GtkPaned *paned
);
Obtains the position of the divider between the two panes.
void gtk_paned_set_wide_handle (GtkPaned *paned
,gboolean wide
);
Sets the “wide-handle” property.
Since: 3.16
