Description
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().
Creating a paned widget with minimum sizes.

Functions
gtk_paned_new ()
GtkWidget *
gtk_paned_new (GtkOrientation orientation);
Creates a new GtkPaned widget.
Since 3.0
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_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_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 Details
The “max-position” 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.
Flags: Read
Allowed values: >= 0
Default value: 2147483647
Since 2.4
The “min-position” property
“min-position” gint
The smallest possible value for the position property. This property is derived from the size and shrinkability of the widget's children.
Flags: Read
Allowed values: >= 0
Default value: 0
Since 2.4
The “position” property
“position” gint
Position of paned separator in pixels (0 means all the way to the left/top).
Flags: Read / Write
Allowed values: >= 0
Default value: 0
The “position-set” property
“position-set” gboolean
TRUE if the Position property should be used.
Flags: Read / Write
Default value: FALSE
Child Property Details
The “resize” child property

The "resize" child property determines whether the child expands and shrinks along with the paned widget.
Flags: Read / Write
Default value: TRUE
Since 2.4
The “shrink” child property
“shrink” gboolean
The "shrink" child property determines whether the child can be made smaller than its requisition.

Default value: 5
Signal Details
The “accept-position” signal
gboolean user_function (GtkPaned *widget, gpointer user_data)
The ::accept-position signal is a keybinding signal which gets emitted to accept the current position of the handle when moving it using key bindings.
The default binding for this signal is Return or Space.
Parameters
widget |
the object that received the signal |
|
user_data |
user data set when the signal handler was connected. |
Flags: Action
Since 2.0
The “cancel-position” signal
gboolean user_function (GtkPaned *widget, gpointer user_data)
The ::cancel-position signal is a keybinding signal which gets emitted to cancel moving the position of the handle using key bindings. The position of the handle will be reset to the value prior to moving it.
The default binding for this signal is Escape.
Parameters

the object that received the signal |
|
user_data |
user data set when the signal handler was connected. |
Flags: Action

gboolean user_function (GtkPaned *widget, gboolean reversed, gpointer user_data)
The ::cycle-child-focus signal is a keybinding signal which gets emitted to cycle the focus between the children of the paned.
The default binding is f6.
Parameters
widget |
the object that received the signal |
|

The “cycle-handle-focus” signal
gboolean user_function (GtkPaned *widget, gboolean reversed, gpointer user_data)
The ::cycle-handle-focus signal is a keybinding signal which gets emitted to cycle whether the paned should grab focus to allow the user to change position of the handle by using key bindings.
The default binding for this signal is f8.
Parameters
widget |
