void Goocanvas::ItemModel::add_child ( const Glib::RefPtr< ItemModel >&  child,
int  position 
)

Adds a child at the given stack position.

Parameters
childThe child to add.
positionThe position of the child, or -1 to place it last (at the top of the stacking order).

void Goocanvas::ItemModel::animate ( double  x,
double  y,
double  scale,
double  degrees,
bool  absolute,
int  duration,
int  step_time,
AnimateType  animate_type 
)

Animates a model from its current position to the given offsets, scale and rotation.

Parameters
xThe final x coordinate.
yThe final y coordinate.
scaleThe final scale.
degreesThe final rotation. This can be negative to rotate anticlockwise, and can also be greater than 360 to rotate a number of times.
absoluteIf the x, y, scale and degrees values are absolute, or relative to the current transform. Note that absolute animations only work if the model currently has a simple transform. If the model has a shear or some other complicated transform it may result in strange animations.
durationThe duration of the animation, in milliseconds (1/1000ths of a second).
step_timeThe time between each animation step, in milliseconds.
animate_typeSpecifies what happens when the animation finishes.

void Goocanvas::ItemModel::set_parent ( const Glib::RefPtr< ItemModel >&  parent)

This function is only intended to be used when implementing new canvas item models (specifically container models such as Goo::CanvasGroupModel).

It sets the parent of the child model. <!–PARAMETERS–> <note><para> This function cannot be used to add a model to a group or to change the parent of a model. To do that use the Goo::CanvasItemModel::property_parent() property. </para></note>

Parameters
parentThe new parent item model.
virtual void Goocanvas::ItemModel::set_parent_vfunc ( const Glib::RefPtr< ItemModel >&  parent)
protectedvirtual
void Goocanvas::ItemModel::set_simple_transform ( double  x,
double  y,
double  scale,
double  rotation 
)

A convenience function to set the item model's transformation matrix.

Parameters
xThe x coordinate of the origin of the model's coordinate space.
yThe y coordinate of the origin of the model's coordinate space.
scaleThe scale of the model.
rotationThe clockwise rotation of the model, in degrees.
void Goocanvas::ItemModel::set_style ( const Glib::RefPtr< Style >&  style)

Sets the model's style, by copying the properties from the given style.

Parameters
styleA style.
virtual void Goocanvas::ItemModel::set_style_vfunc ( const Glib::RefPtr< Style >&  style)
protectedvirtual
void Goocanvas::ItemModel::set_transform ( const Cairo::Matrix transform)

Sets the transformation matrix of an item model.

Parameters
transformThe new transformation matrix, or 0 to reset the transformation to the identity matrix.
