<span class="sd"> Manage tracks and viewers on a screen (Pygame surface.)</span>
|
||||
|
||||
<span class="sd"> The size and number of tracks are defined by passing in at least two</span>
|
||||
<span class="sd"> ratios, e.g. Display(screen, 1, 4, 4) would create three tracks, one</span>
|
||||
<span class="sd"> small one on the left and two larger ones of the same size, each four</span>
|
||||
<span class="sd"> times wider than the left one.</span>
|
||||
|
||||
<span class="sd"> All tracks take up the whole height of the display screen. Tracks</span>
|
||||
<span class="sd"> manage zero or more Viewers. When you "grow" a viewer a new track is</span>
|
||||
<span class="sd"> created that overlays or hides one or two existing tracks, and when</span>
|
||||
<span class="sd"> the last viewer in an overlay track is closed the track closes too</span>
|
||||
<span class="sd"> and reveals the hidden tracks (and their viewers, if any.)</span>
|
||||
|
||||
<span class="sd"> In order to facilitate command underlining while mouse dragging the</span>
|
||||
<span class="sd"> lookup parameter must be a function that accepts a string and returns</span>
|
||||
<span class="sd"> a Boolean indicating whether that string is a valid Joy function name.</span>
|
||||
<span class="sd"> Typically you pass in the __contains__ method of the Joy dict. This</span>
|
||||
<span class="sd"> is a case of breaking "loose coupling" to gain efficiency, as otherwise</span>
|
||||
<span class="sd"> we would have to e.g. send some sort of lookup message to the</span>
