I thought of this option but even that wont work out. I have a
TreeGrid object and to populate it I have created a class which
extends DataSource.
TreeGrid treeGrid = new TreeGrid();
TaskXmlDS taskXmlDS = TaskXmlDS.getInstance();
treeGrid.setDataSource(taskXmlDS);
import com.smartgwt.client.data.DataSource;
import com.smartgwt.client.data.fields.DataSourceIntegerField;
import com.smartgwt.client.data.fields.DataSourceTextField;
public class TaskXmlDS extends DataSource {
private static TaskXmlDS instance = null;
public static TaskXmlDS getInstance() {
if (instance == null) {
instance = new TaskXmlDS("taskXmlDS");
}
return instance;
}
public TaskXmlDS(String id) {
setID(id);
setRecordXPath("/tasks/task");
DataSourceTextField taskNameField = new DataSourceTextField
("taskName", "Task Name" , 128);
DataSourceTextField taskNameDesc = new DataSourceTextField
("taskDesc", "Description", 100);
DataSourceTextField taskStartTime = new DataSourceTextField
("taskStartTime", "Start Time", 80);
DataSourceTextField taskEndTime = new DataSourceTextField
("taskEndTime", "End Time", 80);
DataSourceIntegerField taskIdField = new DataSourceIntegerField
("taskId", "Task ID");
taskIdField.setPrimaryKey(true);
taskIdField.setRequired(true);
DataSourceIntegerField taskParentId = new DataSourceIntegerField
("taskParentId", "Parent ID");
taskParentId.setRequired(true);
taskParentId.setForeignKey(id + ".taskId");
taskParentId.setRootValue("1");
setFields(taskIdField, taskParentId, taskNameField,
taskNameDesc,
taskStartTime, taskEndTime);
setDataURL("tasks.data.xml");
setClientOnly(true);
}
}
In the second last line of code I need to pass the name of an XML
file.
This is why I want to create a XML file.
