Hello,
In my beginner app I build a table. The data comes from a database.
If you click on a button a new window open and shows the table and rows.
All works fine. For the first click the table shows 10 rows. But, if you
click the second time you see 20 rows. All data are duplicated. Next time
you see 30 rows.
I think I have a little logic problem :-)
The data from the remote request is ok, it is always 10 rows.
The code for the table model:
---------------------------------------------------
qx.Class.define("mytestapp.jobstatus",
{
extend : qx.ui.window.Window,
construct : function(UserID) {
// Call super class
this.base(arguments, this.tr("Job Status Information"));
var mycellrenderer = new mytestapp.MyCellRenderer();
// Enable logging in debug variant
if (qx.core.Variant.isSet("qx.debug", "on"))
{
// support native logging capabilities, e.g. Firebug for Firefox
qx.log.appender.Native;
// support additional cross-browser console. Press F7 to toggle
visibility
qx.log.appender.Console;
}
this.setLayout(new qx.ui.layout.VBox(10));
this.setStatus("Application is ready");
var tableModel = new qx.ui.table.model.Simple();
tableModel.setColumns([ this.tr("State"), this.tr("FileName"),
this.tr("FileSize"), this.tr("Date") ]);
var table = new qx.ui.table.Table(tableModel);
table.setLayoutProperties({top: 120});
table.setLayoutProperties({left: 200});
table.setWidth(500);
table.setHeight(200);
with (table) {
getSelectionModel().setSelectionMode(qx.ui.table.selection.Model.SINGLE_SELECTION);
setColumnWidth(0, 50);
setColumnWidth(1, 200);
setColumnWidth(2, 80);
setColumnWidth(3, 150);
};
this.add(table);
var rowcount = tableModel.getRowCount();
//alert('Table row count is:' + rowcount);
table.addListener('appear',function(){
var req = new qx.io.remote.Request(
"http://localhost/mytestapp/jobstatus.php";,
"GET",
"application/json");
req.addListener("completed", function(e) {
try
{
var content = e.getContent();
if (content.length > 0) {
//tableModel.setData(content);
var row;
var dateFormat = new
qx.util.format.DateFormat("dd.MM.yyyy
HH:mm:ss");
var tcm1 =
table.getTableColumnModel();
// set column 3 to date format
var cellrenderer = new
qx.ui.table.cellrenderer.Date();
cellrenderer.setDateFormat(new
qx.util.format.DateFormat("dd.MM.yyyy HH:mm:ss"));
tcm1.setDataCellRenderer(3,
cellrenderer);
for (var i=0; i<content.length;
i++) {
row = [];
row[0] = content[i][0];
row[1] = content[i][1];
row[2] = content[i][2];
row[3] =
dateFormat.parse(content[i][3]);
tableModel.addRows([row]);
}
}//if
}
catch (e)
{
alert("Fehler bei Erhalt des JobStatus: " +
e.toString());
}
});
req.setParameter("UserID", UserID);
//req.setParameter("UserID", 3);
req.send();
});
var tcm = table.getTableColumnModel();
// Use the custom cell renderer for column 1
tcm.setDataCellRenderer(0, new mytestapp.MyCellRenderer());
}//main function
//}//menbers
});
any idea where the problem is? Is there a need to reset the table rows?
best regards
Hans
