a View which can hold DisplayObjects, can make selections, move them around etc.
|
|
|
44 |
this is an abstract class providing common mechanisms - actual instances are
|
|
|
45 |
DrawView, DirectoryView, LogicView or DocumentView.

|

Instance variables:
|
|
|
48 |
|
|
|
49 |
contents <Collection> the objects. The order in which
|
|
|
50 |
these are in that collection defines
|
|
|
51 |
their appearance in the z-plane:
|
|
|
52 |
an object located after another one
|
|
|
53 |
here will be drawn ABOVE the other.
|
|
|
54 |
|
|
|
55 |
sorted <Boolean> if set, redraw and picking methods
|
|
|
56 |
assume that the objects are sorted by
|
|
|
57 |
>= y-coordinates. These operations are
|
|
|
58 |
a bit faster then, since a binary search
|
|
|
59 |
can be done. (use with care).
|
|
|
60 |
|
|

61 |
lastButt <Point> last pointer press position
|
|
|
62 |
(internal)
|
|
|
63 |
|
|
|
64 |
pressAction <Block> action to perform when mouse pointer
|
|
|
65 |
is pressed. Can be set to something like
|
|
|
66 |
[self startCreate], [self startSelectOrMove]
|
|
|
67 |
etc.
|
|
|
68 |
|
|
|
69 |
releaseAction <Block> action to perform when mouse pointer is
|
|
|
70 |
released. Typically set in one of the
|
|
|
71 |
startXXX methods.
|
|
|
72 |
|
|
|
73 |
shiftPressAction <Block> like pressAction, if shift key is
|
|
|
74 |
pressed.
|
|
|
75 |
|
|
|
76 |
doublePressAction <Block> same for double-clicks
|
|
|
77 |
|
|

78 |
motionAction <Block> action to perform on mouse-pointer
|
|
|
79 |
motion.

|
|
81 |
keyPressAction <Block> action for keyboard events
|
|
|
82 |

canDragOutOfView <Boolean> if true, objects can be dragged out of the

this view.

aligning <Boolean> if true, pointer positions are

115 |
aligned (snapped) to the point
|

|
116 |
specified in gridAlign
|
|
|
117 |
|

118 |
gridAlign <Point> if aligning is true, this point

defines the snapping. For example,

typically, ObjectViews are not used on their own, but instead
|
|
|
130 |
subclassed and thereby provide the common functionality for
|
|
|
131 |
views which show (possibly overlapping) objects.
|
|
|
132 |
The methods here provide all mechanisms to handle redraws, picking
|
|
|
133 |
(i.e. finding an object by position), gridding, moving objects with
|
|
|
134 |
minimum redraw etc.
|
|
|
135 |
Also, zooming and scrolling is handled.
|
|
|
136 |
All objects which respond to the DisplayObject protocol can be handled
|
|
|
137 |
by ObjectView - therefore, you can add almost any object and have it
|
|
|
138 |
displayed and handled here. (as an example, try to copy a LogicGate
|
|
|
139 |
from a LogicView and paste it into a DrawTool - it will work).
|
|
|
140 |
|
|
|
141 |
Reminder: ObjectViews are not to be used as below, but instead to be
|
|
|
142 |
subclassed. Therefore, the examples below are somewhat untypical.
|
|
|
