Class Box
This is the base class of HBox and VBox. It has the code necessary to
maintain the contained list of widgets, but it does not position them.
Box uses a notion of
packing. Packing refers to adding widgets
with reference to a particular position in a Container. For a Box, there are
two reference positions: the start and the end of the box. For a VBox, the
start is defined as the top of the box and the end is defined as the bottom.
For a HBox the start is defined as the left side and the end is defined as
the right side.
Use repeated calls to
packStart
to pack widgets into a Box
from start to end. Use
packEnd
to add widgets from end to
start. You may intersperse these calls and add widgets from both ends of the
same Box.
boolean | getHomogeneous() - Returns whether the box is homogeneous (all children are the same size).
|
int | getSpacing() - Gets the spacing between the children of the box.
|
static Type | getType() - Retrieve the runtime type used by the GLib library.
|
void | packEnd(Widget child) - Adds child to the box, packed with reference to the end of box.
|
void | packEnd(Widget child, boolean expand, boolean fill, int padding) - Adds child to the box, packed with reference to the end of box.
|
void | packStart(Widget child) - Adds child to the box, packed with reference to the start of box.
|
void | packStart(Widget child, boolean expand, boolean fill, int padding) - Adds child to the box, packed with reference to the start of box.
|
void | reorderChild(Widget child, int position) - Moves child to a new position in the list of box children.
|
void | setHomogeneous(boolean homogenous) - Sets the homogeneous field of Box, controlling whether or not
all children of box are given equal space in the box.
|
void | setSpacing(int spacing) - Sets the number of pixels to place between children of the box.

getHomogeneous
public boolean getHomogeneous()
Returns whether the box is homogeneous (all children are the same size).
- TRUE if the box is homogeneous.
getSpacing
public int getSpacing()
Gets the spacing between the children of the box.
getType
public static Type getType()
Retrieve the runtime type used by the GLib library.
- getType in interface Container
packEnd
public void packEnd(Widget child)
Adds child to the box, packed with reference to the end of box. The child
is packed before any other child packed with reference to the end of box.
This method takes the default values for expansion, fill and padding.
child
- The widget to be added to the box.
packEnd
public void packEnd(Widget child,
boolean expand,
boolean fill,
int padding)
Adds child to the box, packed with reference to the end of box. The child
is packed after any other child packed with reference to the end of box.
This method allows you to define the properties of the packing.
child
- The widget to be added.expand
- TRUE if the new child is to be given extra space allocated to
box. The extra space will be divided evenly between all
children of box that use this option.fill
- TRUE if space given to child by the expand option is actually
allocated to child, rather than just padding it. This
parameter has no effect if expand is set to FALSE. A child is
always allocated the full height of a HBox and the full width
of a VBox. This option affects the other dimension.padding
- Extra space in pixels to put between this child and its
neighbors, over and above the global amount specified by
spacing in Box. If child is a widget at one of the reference
ends of box, then padding pixels are also put between child
and the reference edge of Box.
packStart
public void packStart(Widget child)
Adds child to the box, packed with reference to the start of box. The
child is packed after any other child packed with reference to the start
of box. This method takes the default values for expansion, fill and
padding.
child
- The widget to be added to the box.
packStart
public void packStart(Widget child,
boolean expand,
boolean fill,
int padding)
Adds child to the box, packed with reference to the start of box. The
child is packed after any other child packed with reference to the start
of box. This method allows you to define the properties of the packing.
child
- The widget to be added.expand
- TRUE if the new child is to be given extra space allocated to
box. The extra space will be divided evenly between all
children of box that use this option.fill
- TRUE if space given to child by the expand option is actually
allocated to child, rather than just padding it. This
parameter has no effect if expand is set to FALSE. A child is
always allocated the full height of a HBox and the full width
of a VBox. This option affects the other dimension.padding
- Extra space in pixels to put between this child and its
neighbors, over and above the global amount specified by
spacing in Box. If child is a widget at one of the reference
ends of box, then padding pixels are also put between child
and the reference edge of Box.
reorderChild
public void reorderChild(Widget child,
int position)
Moves child to a new position in the list of box children.
A widget's position in the box children list determines where the widget
is packed into box. A child widget at some position in the list will be
packed just after all other widgets of the same packing type that appear
earlier in the list.
child
- The widget to moveposition
- The new position for child in the box, starting from 0. If
negative, the end of the list is used.
setHomogeneous
public void setHomogeneous(boolean homogenous)
Sets the homogeneous field of Box, controlling whether or not
all children of box are given equal space in the box.
homogenous
- A boolean value, TRUE to create equal allotments, FALSE for
variable allotments.
setSpacing
public void setSpacing(int spacing)
Sets the number of pixels to place between children of the box.
spacing
- The number of pixels to put between children.
