Changes from Dojo 0.4 dojo.widgets to new dijit project
|
|
|
2 |
=======================================================
|
|
|
3 |
|
|
|
4 |
The widgets and widget infrastructure have been separated into separate project,
|
|
|
5 |
vastly streamlined and with a new directory structure. There are many other changes.
|
|
|
6 |
|
|
|
7 |
Markup
|
|
|
8 |
------
|
|
|
9 |
|
|
|
10 |
dojoType="button" replaced by dojoType="dijit.Button" Must use fully qualified class name,
|
|
|
11 |
and it's case-sensitive.
|
|
|
12 |
|
|
|
13 |
Need to manually dojo.require("dojo.parser") to get parsing
|
|
|
14 |
|
|
|
15 |
Widget namespaces and widget auto-loading are desupported.
|
|
|
16 |
|
|
|
17 |
onClick="foo" now overrides (ie, replaces) the default onClick() function rather than attaching to it,
|
|
|
18 |
so widget designers should make empty onClick() functions (when appropriate).
|
|
|
19 |
|
|
|
20 |
Programmatic creation
|
|
|
21 |
---------------------
|
|
|
22 |
Create widgets via
|
|
|
23 |
|
|
|
24 |
new dijit.Button(params, srcNodeRef)
|
|
|
25 |
|
|
|
26 |
createWidget() call removed since multiple renderers are no longer supported (see next section).
|
|
|
27 |
|
|
|
28 |
At least for the dijit widgets, all widgets are guaranteed to work programmatically, which in
|
|
|
29 |
effect means that all widgets must have templates, unless the default <div> works.
|
|
|
30 |
|
|
|
31 |
Renderers
|
|
|
32 |
---------
|
|
|
33 |
Removed support for multiple renderers (svg & vml & a11y) for a single widget.
|
|
|
34 |
If a widget wants to render differently on different platforms, there must be
|
|
|
35 |
branching code inside the widget, or it needs to call a library that branches
|
|
|
36 |
based on the browser type (like dojo.gfx or dojo.charting).
|
|
|
37 |
|
|
|
38 |
|
|
|
39 |
Templates
|
|
|
40 |
---------
|
|
|
41 |
"this." is no longer used within ${} substitution notation. See ticket #2905.
|
|
|
42 |
dojoRoot,buildScriptBase,dojoModuleUrl are no longer supported, but
|
|
|
43 |
any JavaScript properties on the widget's 'this' may be referenced with dotted notation.
|
|
|
44 |
The attributes dojoOn* are desupported (including dojoOnBuild);
|
|
|
45 |
also can't use id attribute to affect a dojoAttachPoint.
|
|
|
46 |
|
|
|
47 |
dojoAttachEvent is case sensitive, so capitalization matters. You will probably have
|
|
|
48 |
to change
|
|
|
49 |
|
|
|
50 |
dojoAttachEvent="onClick"
|
|
|
51 |
|
|
|
52 |
to
|
|
|
53 |
|
|
|
54 |
dojoAttachEvent="onclick: onClick"
|
|
|
55 |
|
|
|
56 |
(given that the event name is lowercase, and assuming that the method name is camel case)
|
|
|
57 |
|
|
|
58 |
lists within dojoAttachPoint, dojoAttachEvent, waiRole, and waiState are now comma-separated
|
|
|
59 |
(not separated by semi-colons)
|
|
|
60 |
|
|
|
61 |
Standard HTML attributes like 'id', 'name', 'lang', etc. are carried over programmatically
|
|
|
62 |
by the _Widget constructor and do not need to be declared in the template (see _Widget.attributeMap)
|
|
|
63 |
|
|
|
64 |
Parent/Child relationships
|
|
|
65 |
--------------------------
|
|
|
66 |
By default widgets exist as islands, not knowing about their parent widget or children widgets.
|
|
|
67 |
The exception is the destroy() function which will also delete all descendant widgets.
|
|
|
68 |
Some widgets like Tree and SplitContainer will know about their children, but those widgets
|
|
|
69 |
will use the special mixins in Container.js / Layout.js.
|
|
|
70 |
|
|
|
71 |
Widget.js base class
|
|
|
72 |
--------------------
|
|
|
73 |
|
|
|
74 |
- Widget.js, Domwidget.js, HtmlWidget.js combined into dijit.base.Widget, with TemplatedWidget mixin
|
|
|
75 |
for widgets with templates
|
|
|
76 |
|
|
|
77 |
- on widget creation, postMixInProperties(), buildRendering() and postCreate() is called.
|
|
|
78 |
fillInTemplate() is no longer called. In addition, those functions call signatures have changed.
|
|
|
79 |
No arguments are passed. To get the source dom Node, just reference this.srcDomNode.
|
|
|
80 |
When postCreate() is called the widget children don't yet exist.
|
|
|
81 |
|
|
|
82 |
- The TemplatedWidget mixin defines buildRendering(). widgetsInTemplate not ported yet.
|
|
|
83 |
|
|
|
84 |
- onResized() removed
|
|
|
85 |
|
|
|
86 |
- the whole parent/child relationship thing is gone
|
|
|
87 |
|
|
|
88 |
- extraArgs[] is gone
|
|
|
89 |
|
|
|
90 |
- postCreate() called but child widgets don't exist yet
|
|
|
91 |
|
|
|
92 |
- templateCssPath ignored. User must manually include tundra.css file
|
|
|
93 |
