public class simple_grow_container
extends uni_container
implements pressable, grow_draggable

A container class for one object that provides a grow handle. This establishes constraints on its child so that it follows the size of this object as it grows.

Field Summary
`protected loaded_image`	`_handle` Image for the grow handle

Constructor Detail

simple_grow_container

public simple_grow_container(int x,
                             int y,
                             int w,
                             int h,
                             loaded_image hnd_img)

Full constructor. The boolean parameter controls whether the container does bounding box feedback, or simply grows with no other specific feedback.

Parameters:: int - x the initial x position of this object.; int - y the initial y position of this object.; int - w the initial width of this object.; int - w the initial height of this object.; loaded_image - hnd_img an image for the grow handle.

Method Detail

handle

public loaded_image handle()

Image for the grow handle.

Returns:: loaded_image the current image for the grow handle.

set_handle

public void set_handle(loaded_image himg)

Set the image used for the grow handle.

Parameters:: loaded_image - himg the new image for the grow handle.

set_child

public void set_child(int at_indx,
                      interactor chld)

Override set_child to establish and/or remove constraints.

Parameters:: int - at_indx the index to place the child at.; interactor - chld the child interactor.
Overrides:: set_child in class base_interactor

remove_child

public interactor remove_child(int at_indx)

Override remove_child to drop constraints.

Parameters:: int - at_index index of child to remove.
Returns:: interactor the removed child.
Overrides:: remove_child in class base_interactor
