<td colspan=2><tt>Displayables are objects which are displayed on the screen.<br>
<br>
This is just the abstract class, defining basic operations<br>
such as resizing, printing, changing colors.<br>
Subclasses of displayable can extend these methods:<br>
<br>
<a href="#Displayable-draw">draw</a>() -- draw the object. Is only called if visible.<br>
<a href="#Displayable-poke">poke</a>() -- is called just before <a href="#Displayable-draw">draw</a>(), even if not visible.<br>
<a href="#Displayable-finalize">finalize</a>() -- called after all objects finished drawing.<br>
<a href="#Displayable-click">click</a>(event) -- called with a MouseEvent. This is called on all<br>
visible objects under the mouse, until one returns True.<br>
<a href="#Displayable-press">press</a>(key) -- called after a key press on focused objects.<br>
<a href="#Displayable-destroy">destroy</a>() -- called before destroying the displayable object<br>
<br>
Additionally, there are these methods:<br>
<br>
<a href="#Displayable-__contains__">__contains__</a>(item) -- is the item (y, x) inside the widget?<br>
<br>
These attributes are set:<br>
<br>
Modifiable:<br>
focused -- Focused objects receive <a href="#Displayable-press">press</a>() calls.<br>
visible -- Visible objects receive <a href="#Displayable-draw">draw</a>() and <a href="#Displayable-finalize">finalize</a>() calls<br>
need_redraw -- Should the widget be redrawn? This variable may<br>
be set at various places in the script and should eventually be<br>
handled (and unset) in the <a href="#Displayable-draw">draw</a>() method.<br>
<br>
Read-Only: (i.e. reccomended not to change manually)<br>
win -- the own curses window object<br>
parent -- the parent (<a href="#DisplayableContainer">DisplayableContainer</a>) object or None<br>
x, y, wid, hei -- absolute coordinates and boundaries<br>
settings, fm, env -- inherited shared variables<br> </tt></td></tr>
