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 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().
Example 91. Creating a paned widget with minimum sizes.

GtkWidget * gtk_paned_new (GtkOrientation orientation);
Creates a new GtkPaned widget.
|
the paned's orientation. |
Returns : |
a new GtkPaned. |
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).
|
a paned widget |
|
the child to add |
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).
|
a paned widget |
|
the child to add |
void gtk_paned_pack1 (GtkPaned *paned,GtkWidget *child,gboolean resize,gboolean shrink);
Adds a child to the top or left pane.
|
a paned widget |
|
the child to add |
|
should this child expand when the paned widget is resized. |
|
can this child be made smaller than its requisition. |
void gtk_paned_pack2 (GtkPaned *paned,GtkWidget *child,gboolean resize,gboolean shrink);
Adds a child to the bottom or right pane.
|
a paned widget |
|
the child to add |
|
should this child expand when the paned widget is resized. |
|
can this child be made smaller than its requisition. |
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.
|
a GtkPaned widget |
|
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.
|
a GtkPaned widget |
Returns : |
position of the divider |
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.
|
a GtkPaned |
Returns : |
the paned's handle window. [transfer none] |
Since 2.20
"max-position" property"max-position" gint : Read
The largest possible value for the position property. This property is derived from the size and shrinkability of the widget's children.
Allowed values: >= 0

Since 2.4
"min-position" property"min-position" gint : Read
The smallest possible value for the position property. This property is derived from the size and shrinkability of the widget's children.

"resize" child property"resize" gboolean : Read / Write
The "resize" child property determines whether the child expands and shrinks along with the paned widget.
Default value: TRUE
Since 2.4
"shrink" child property"shrink" gboolean : Read / Write

Width of handle.
Allowed values: >= 0
Default value: 5
"accept-position" signalgboolean user_function (GtkPaned *widget,
gpointer user_data) : Action
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.
