    text
    copied!<p>I'm making an Eclipse (3.6.2) CDT (7.0.2) Plugin which uses my own wizard page (extending MBSCustomPage). This wizard page shows a Table filled with some TableItems that can be checked or unchecked by clicking on them (as usual). <strong>The problem is that I'm always receiving two events when a TableItem checkbox is cheked (or unchecked)!</strong>. In the first event received, I have a (SelectedEvent)e.detail == SWT.CHECK, even if the TableItem was checked first, and in the second event, the (SelectedEvent)e.detail == 0!. So I have no way to know if the TableItem is really checked or not. This is my code (somewhat):</p> <pre><code>final Table table = new Table( composite, SWT.BORDER | SWT.SINGLE | SWT.FULL_SELECTION | SWT.CHECK ); table.setHeaderVisible(true); table.setLinesVisible(false); (...) table.addSelectionListener(new SelectionAdapter() { public void widgetSelected(SelectionEvent e) { CheckThatOnlyOneItemCanBeCheckedAtTime(e.item); //If someone check on me, save the item data value in a "container" if( e.detail == SWT.CHECK ) { MBSCustomPageManager.addPageProperty(PAGE_ID, "SDK_Path", ((ISdk)((TableItem)e.item).getData()).getPath() ); } else { //Otherwise, unset the saved value MBSCustomPageManager.addPageProperty(PAGE_ID, "SDK_Path", "" ); } } }); </code></pre> <p>Why is widgetSelected() being called two times when I click on the checkbox of a TableItem? I tested that the events are fired even if there is no code inside the widgetSelected() method. I didn't find anything Googling around or looking in Eclipse Bugzilla database... really strange to me, but I'm not an experienced Eclipse plugin coder (not even Java) :)</p> <p>Thanks!</p>
