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
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.
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
gtk_paned_set_position()
.
Example 45. Creating a paned widget with minimum sizes.

Functions
gtk_paned_add1 ()
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)
.
gtk_paned_add2 ()
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)
.
gtk_paned_gutter_size()
#define gtk_paned_gutter_size(p,s) (void) 0
gtk_paned_gutter_size
is deprecated and should not be used in newly-written code.
Old name for gtk_paned_set_gutter_size()
.
gtk_paned_pack1 ()
void gtk_paned_pack1 (GtkPaned *paned
,GtkWidget *child
,gboolean resize
,gboolean shrink
);
Adds a child to the top or left pane.
gtk_paned_pack2 ()
void gtk_paned_pack2 (GtkPaned *paned
,GtkWidget *child
,gboolean resize
,gboolean shrink
);
Adds a child to the bottom or right pane.
gtk_paned_get_child1 ()
GtkWidget *
gtk_paned_get_child1 (GtkPaned *paned
);
Obtains the first child of the paned widget.
Since: 2.4
gtk_paned_get_child2 ()
GtkWidget *
gtk_paned_get_child2 (GtkPaned *paned
);
Obtains the second child of the paned widget.
Since: 2.4
gtk_paned_set_gutter_size()
#define gtk_paned_set_gutter_size(p,s) (void) 0
gtk_paned_set_gutter_size
is deprecated and should not be used in newly-written code.
In older versions of GTK+, this function used to set the width of the gutter (the area between the two panes). It does nothing now.
gtk_paned_set_position ()
void gtk_paned_set_position (GtkPaned *paned
,gint position
);
Sets the position of the divider between the two panes.
Parameters
paned |
a GtkPaned widget |
|
position |
pixel position of divider, a negative value means that the position is unset. |
gtk_paned_get_position ()
gint
gtk_paned_get_position (GtkPaned *paned
);
Obtains the position of the divider between the two panes.
gtk_paned_get_handle_window ()
GdkWindow *
gtk_paned_get_handle_window (GtkPaned *paned
);
Returns the GdkWindow of the handle. This function is useful when handling button or motion events because it enables the callback to distinguish between the window of the paned, a child and the handle.
Since: 2.20

property
“max-position” gint
The largest possible value for the position property. This property is derived from the size and shrinkability of the widget's children.

property
“min-position” gint

Default value: 0
Since: 2.4
The “position”
property
