  1. POSmartGWT - Update ListGridRecord dynamically
    text
    copied!<p>I am using SmartGWT and I have a ListGrid populated with an array of ListGridRecords using the setData() call. I am trying to update a progress property of a single record (on a timer for testing) and have it update in the browser. I have tried various combinations of draw(), redraw(), markForRedraw() etc. to no avail. </p> <p>I also tried overriding the updateRecordComponent() method in my table class, but it only gets called when the records are first created (after createRecordComponent()).</p> <p>I should note that I do NOT want to accomplish this by binding to a DataSource. I just want to be able to update the attribute on the client-side.</p> <pre><code>ArrayList&lt;SegmentSortRecord&gt; mRecords; mRecords.add(new SegmentSortRecord("03312010_M001_S004")); mRecords.add(new SegmentSortRecord("03312010_M001_S005")); mRecords.add(new SegmentSortRecord("03312010_M001_S006")); mRecords.add(new SegmentSortRecord("03312010_M001_S007")); SegmentSortRecord[] records = new SegmentSortRecord[mRecords.size()]; mRecords.toArray(records); mSortProgressTable.setData(records); </code></pre> <p>. . .</p> <pre><code>mTestTimer = new Timer() { public void run() { mTestPercent += 5; if (mTestPercent &lt;= 100) { mSortProgressTable.getRecord(2).setAttribute(Constants.PROGRESS_COL_NAME, mTestPercent); //mSortProgressTable.markForRedraw(); //mSortProgressTable.redraw(); } else { mTestPercent = 0; } } }; </code></pre> <p>...</p> <pre><code>@Override protected Canvas createRecordComponent(final ListGridRecord aRecord, Integer aColumn) { String fieldName = getFieldName(aColumn); // Want to override the behavior for rendering the "progress" field if (fieldName.equals(Constants.PROGRESS_COL_NAME)) { Progressbar bar = new Progressbar(); bar.setBreadth(10); bar.setLength(100); // The JavaScript record object contains attributes that we can // access via 'getAttribute' functions. bar.setPercentDone(aRecord.getAttributeAsInt(Constants.PROGRESS_COL_NAME)); return bar; } </code></pre> <p>Thanks in advance for any help.</p>
