public class isolation_semantic_lens
extends focus_semantic_lens

Class to implement dragging and drawing for a semantic lens. When this object is drawn, it does a traversal of the subtree rooted at the parent of this object. That traversal does an alternate rendering (semantic redraw) of the subtree within the bounds of this object. This redraw can be done on top of the normal draw (by setting clear_back false, which is the default), or the normal drawing can be cleared and replaced the alternate rendering. Alternate renderings are done via a "interactor_predicate" object that parameterizes this object and is passed to a traverse_and_collect() of the parent.

This object provides a title bar (with an optional text title) that can be used to move the lens, as well as a small grow handle to resize it. For complete operation, this object should be placed under a semantic_lens_parent object (the object will work with other parents, but redraw anomalies for dynamically moving objects within the lens can occur). This lens provides crosshairs to focus it on a particular interactor.

                               int wv,

Simplest constructor. Defaults to 0,0 : 100x100 with non-cleared background.

Method Detail

isolation_sem_draw_kind

public int isolation_sem_draw_kind()
Identifier for the particular kind of semantic redraw pass being done here.
Returns:
int a unique identifier for this kind of redraw.

callback

public void callback(interactor from_obj,
                     event evt,
                     int callback_num,
                     java.lang.Object callback_info)
Overrides:
callback in class focus_semantic_lens

draw_self_local

protected void draw_self_local(drawable d)
Override draw_self to do a semantic lens. This works by going up one level to the parent, then doing a sem_draw traversal from there down. the sem_draw traversal draws a semantically modified rendition of the sub-tree on our drawable.

Note, this drawing is done inside our bounds, but the drawing corresponding to each individual object found in the traversal starting from our parent is not limited to their bounds. This requires special processing in damage_self within our parent.

Parameters:
drawable - d the drawing surface we draw on.
Overrides:
draw_self_local in class focus_semantic_lens
