| <h1>How to extract an SWT widget from ECL command?</h1> |
| <p></p> |
| |
| <div class="panel panel-default"> |
| <div class="panel-body"> |
| <i> I am trying to make a custom ECL command to extract a data from table in order to make my custom assertions on that data. |
| I want to use the result of: get-table | ...<br> |
| But when I read an object from process.getInput().read(), I get an object of the class ControlHandlerImpl and I don't know how to handle this further. |
| Do you have some examples using the input pipe?</i> |
| </div> |
| </div> |
| |
| <p>When RCPTT passes controls around (like in 'get-view "..." | get-tree), it does not operate on widgets, instead, a special descriptor EMF objects used. |
| There is a special command get-object, which allows to extract an actual widget object and pass it to other command.<br> |
| Therefore, while writing custom command, it is better to declare an input parameter in EMF model as EJavaObject and then use it like this:<br> <br></p> |
| |
| <div class="panel panel-default"> |
| <div class="panel-body"> |
| get-view "Package Explorer" | get-tree | get-object | my-custom-tree-command |
| </div> |
| </div> |
| |
| <p>A good starting point to look at might be an <a href="http://download.eclipse.org/rcptt/release/1.5.4/doc/ecl/index.html#invoke">invoke</a> command, which takes a Java object from input and invokes methods via reflection.</p> |
| |
| <p>It's model is described like this:</p> |

| An implementation of <a href="http://download.eclipse.org/rcptt/release/1.5.4/doc/ecl/index.html#invoke">invoke</a> command can be found at RCPTT repo.</p> |
