public class switch_lens

extends semantic_lens

implements callback_object

Class to implement dragging and drawing for a simple lens that works with a lens_switch_container object. During drawing, this lens takes its drawable and wraps it in a lens_info_drawable containing an integer (choosen from via its controls) telling any lens_switch_container object that recieves it which of its children to draw. It then invokes draw_self() on its parent with this new drawable (taking care not to recursively draw itself in the process). Unlike other lenses, this one will work with any parent type and does not in fact use the rest of the lens infrastructure at all.

Field Summary

protected int	_current_choice Current selection among our choices
protected spacer	blank
protected column	checkbox_column
protected text_toggle_collection	checkboxes
protected shrink_wrap_container	control_palette
static int	DRAW_KIND unique identifier for traverals

Method Detail

set_fixed

public void set_fixed(boolean b)

Overrides:

set_fixed in class semantic_lens

current_choice

public int current_choice()

public void pick(int pt_x,
                 int pt_y,
                 pick_collector pick_list)

Override pick to just work on handles and let center of lens pass through.

Parameters:

int - pt_x x coordinate of picking point

int - pt_y y coordinate of picking point

pick_collector - pick_list result list

Overrides:

pick in class semantic_lens

press

public boolean press(event evt,

draw_self_local

protected void draw_self_local(drawable d)

Override draw_self to do our special drawing. We basically wrap the drawable with a lens_info_drawable which we tag with the number of our current choice. We then do a redraw of our parent with that (setting a flag so when we are invoked again, we don't recurse.

Overrides:
