  1. POUpdating a specific cell in a JTable using a ComboBox
    text
    copied!<p>I am reading in data using DOM Parser to update a <code>JTable</code>. I have a Column (ValidValues) that may not necessarily be located in the XML. </p> <p>However, if this tag is located when reading in from the XML, I take the value and use this to from an SQL query to return a vector of the records available. </p> <p>I then wish to populate the JTable with a specific combo box of the values returned on the correct row that the tag was read. E.G I may not read a tag until the 17th row has been read in from the XML document.</p> <p>I have already completed two similar JCombo boxes in the same code but they remain constant, so there is no issue with them. </p> <p>As this changes between cells I'm unsure of how to proceed, I looked through Oracle tutorials but they only seem to demonstrate how one column can be changed. Further research has found nothing relating to this area either. </p> <p>Code for constant JComboBox updated through vector:</p> <pre><code> propColumn = table.getColumnModel().getColumn(ENV_PROPERTIES_COLUMN); propComboBox = new JComboBox(); propComboBox.addItem(""); constructEnvProperties(); propColumn.setCellEditor(new DefaultCellEditor(propComboBox)); public void constructEnvProperties(){ IWM781EnvProfilePropertiesCtl ctl = new IWM781EnvProfilePropertiesCtl(); Vector&lt;IWM781EnvProfileProperties&gt; recordSet = ctl.getRecordSet("TestEnvXXX", con); for(int i = 0; i &lt; recordSet.size(); i++){ logger.debug(recordSet.get(i).getProp781Property()); propComboBox.addItem(recordSet.get(i).getProp781Property()); } } </code></pre> <p>Attempt at a variant combo box:</p> <pre><code>if(tableEntryElement.getElementsByTagName("ValidValues").item(0) != null){ // Build combo box based on &lt;SystemCode&gt; tag logger.debug(tableEntryElement.getElementsByTagName("ValidValues").item(0).getTextContent()); TableColumn optionColumn = table.getColumnModel().getColumn(OPTION_COLUMN); JComboBox optionComboBox = new JComboBox(); optionComboBox.addItem(""); constructOptions(tableEntryElement); optionColumn.setCellEditor(new DefaultCellEditor(optionComboBox)); } </code></pre> <p>I know the issue here will be:</p> <pre><code> TableColumn optionColumn = table.getColumnModel().getColumn(OPTION_COLUMN); </code></pre> <p>as it's referencing the entire column, but any ideas would be greatly appreciated.</p> <p>I've also briefly read the API for <code>TableColumn</code> which I'm still in the middle of to see if I can find a way to reference the row of the column.</p> <p>Thanks in advance</p>
