1 == What It Is ==
2
3 Click to Open (C2O) allows you to open components in Eclipse directly from the running application in your browser! Click to Open appears in the lower left corner of browser as part of the pages of your running application. Clicking on this component, and then on an object in the browser window, opens the relevant WOComponent in Eclipse. This makes life easier for UI designers and for developers getting familiar with new projects. It also provides some other very slick debugging tools.

5 Check out the [[screencast at the mDimension build site>>http://webobjects.mdimension.com/wolips/preview/WOLipsFramework.m4v]]
6
7 Click to Open is a browser based extension to WOLips found in [[Project Wonder>>WONDER:Home]]. All of the Wonder ERD2W components support Click to Open.
8
9 **Note that click-to-open support is expensive, because it has to dig around your component HTML quite a bit, so you will take a performance hit in development to have it enabled.**
10
11 == What You Need ==
12
13 You need the **WOLips** framework that is part of Project Wonder. You also need the **ERExtensions** framework that is part of Project Wonder on the class path at runtime. If you already use Project Wonder, are you almost done.
14
15 If you are not using Project Wonder, you can download it from [[mDimension's site>>http://webobjects.mdimension.com/wonder/]], untar the frameworks, and copy just the WOLips.framework and ERExtensions.framework to where you have the rest of your frameworks (usually /Library or ,,/Library).,,
16
17 == Getting Set Up ==
18
19 === Add the WOLips.framework ===
20
21 Follow the [[tutorial>>Add a Framework Dependency]] on adding a framework to add WOLips.framework to your application.
22
23 === Add Support to Component Base Class ===
24
25 If your components extend Wonder's ERXComponent, you can skip this step. Once again, using Wonder makes your life easier.
26
27 If you don't have a custom component base class, you really should. Using com.webobjects.appserver.WOComponent as the super-class for your pages and components is just going to leave you doing the same things over and over. If you don't have one, you might want to start using the ClickToOpenComponent below.
28
29 You will need to add the appendToResponse(WOResponse, WOContext) method below to your component base class, or add this code to your appendToResponse method if you already have one.
30
31 Here is an example implementation of a component base class and of Click to Open support:
32
33 {{code value="java"}}
34
35 package net.com.foo.bar;
36
37 import com.webobjects.appserver.*;
38
39
40 /**
41 * Support for "Click to Open" navigation from the browser to the template in Eclipse. To enable this,
42 * launch with:
43 * <pre>
44 * -Der.component.clickToOpen=true
45 * </pre>
46 */
47 public class ClickToOpenComponent extends com.webobjects.appserver.WOComponent {
48
49 public static final boolean isClickToOpenEnabled = Boolean.getBoolean(System.getProperty("er.component.clickToOpen", "false"));
50
51 public ClickToOpenComponent(WOContext context) {
52 super(context);
53 }
54
55 public void appendToResponse(WOResponse response, WOContext context) {
56 ERXClickToOpenSupport.preProcessResponse(response, context, isClickToOpenEnabled);
57 super.appendToResponse(response, context);
58 ERXClickToOpenSupport.postProcessResponse(getClass(), response, context, isClickToOpenEnabled);
59 }
60 }
61
62 {{/code}}
63
64 For components that can't sub-class ClickToOpenComponent (directly or indirectly), you can enable Click to Open by adding this method to your component:
65
66 {{code value="java"}}
67
68 public void appendToResponse(WOResponse response, WOContext context)
69 {
70 ERXClickToOpenSupport.preProcessResponse(response, context, ClickToOpenComponent.isClickToOpenEnabled);
71 super.appendToResponse(response, context);
72 ERXClickToOpenSupport.postProcessResponse(getClass(), response, context, ClickToOpenComponent.isClickToOpenEnabled);
73 }
74
75 {{/code}}
76
77 **Note that when isClickToOpenEnabled is false, the ERXClickToOpenSupport methods are no-ops.**
78
79 === Add Support to Application ===
80
81 If your Application.java class extends Wonder's ERXApplication, you can skip this step too. Otherwise, add a developmentMode() method like this:
82
83 {{code value="java"}}
84
85 private Boolean isDevelopmentMode;
86 public boolean developmentMode() {
87 if (isDevelopmentMode == null) {
88 isDevelopmentMode = new Boolean(System.getProperty("er.extensions.ERXApplication.developmentMode", "false"));
89 }
90 return isDevelopmentMode.booleanValue();
91 }
92
93 {{/code}}
94
95 === Set Application Properties ===
96
97 In your application's Properties file, add this line:
98
99 {{code}}
100
101 wolips.password=yourpassword
102
103 {{/code}}
104
105 If you need to, you can also change these default values:
106
107 {{code}}
108
109 wolips.host=localhost
110 wolips.port=9485
111
112 {{/code}}
113
114 === Provide prototype.js ===
115
116 WOLips.framework needs a prototype.js. If you are using Ajax framework, you don't need to do anything, because it will default to use Ajax.framework's prototype.js. However, if you are not, add this to your application's Properties file (as an example, change the values as appropriate):
117
118 {{code}}
119
120 wolips.prototype.framework=app
121 wolips.prototype.fileName=prototype.js
122
123 {{/code}}
124
125 === Add WOLToolBar to Your Pages ===
126
127 In your page wrapper's HTML template, add
128
129 {{code value="html"}}
130
131 <wo:WOLToolBar/>
132
133 {{/code}}
134
135 and you're done. If you don't have a [[page wrapper>>WO:Web Applications-Development-Examples-Page Layout]], you will have to add this to every page. Hint: page wrappers make your life easier.
136
137 If you are using the old WO template syntax, add this to the .html file:
138
139 {{code value="html"}}
140
141 <webobject name="WOLToolBar" />
142
143 {{/code}}
144
145 And add this to the .wod file:
146
147 {{code value="html"}}
148
149 WOLToolBar: WOLToolBar{
150 }
151
152 {{/code}}
153
154 === Configure WOLips Server ===
155
156 You must be using a recent version of WOLips that supports the **WOLips Server**. In your WOLips preferences, you must enable the WOLips Server and set the communication password. This password must match the ##wolips.password## in the **Set Application Properties** section above.
157
158 **Turning on the WOLips Server requires Eclipse to be restarted.**
159
160 [[image:WOLipsServerPreferences.png]]
161
162 You can optionally change the port number. If you do change the port number, see ##wolips.port## in the **Set Application Properties** section above.
163
164 === Enable Click to Open ===
165
166 And add **-Der.component.clickToOpen=true** and **-Der.extensions.ERXApplication.developmentMode=true** to the launch arguments:
167
168 [[image:EnableClickToOpen.png]]
169
170 == Using Click to Open ==
171
172 Run your application and look in the lower, left hand corner. You should see a link like this:
173
174 [[image:ClickToOpenLink.png]]
175
176 If you don't, check that the page has the WOLToolBar on it and that the ##er.component.clickToOpen## property is set to true and the ##er.extensions.ERXApplication.developmentMode## property is set to true.
177
178 \\
179
180 Click on this component to open the Click to Open UI:
181
182 [[image:ClickToOpenExpanded.png]]
183
184 **EditDisplayAd** is the page in the browser. Click on this link to open this page in Eclipse.
185
186 \\
187
188 If you are looking for a sub-component of this page, click on the **Click to Open** link. As you move your mouse over the page, the bread crumb of components will change to show you where you are. Just click to open the component under the mouse in Eclipse. It is that easy!

193
194 === Additional Functionality ===
195
196 * Esc is a shortcut for getting out of click-to-open mode
197 * hold down the Cmd key while you move the mouse around and it will highlight the component
198 * Cmd-click it will popup the stack of components and you can pick from the stack:
199 [[image:ComponentStack.png]]
200 * you can the binding ##expanded=true;## on WOLToolBar so it's open by default, instead of closed
