Hi Andreas,
I dont think that I create new objects on the reload of table data. I
something like the following:
I add a table Model with some columns
> this.tableModel = new flare.ui.table.SimpleTableModel();
> this.tableModel.setColumns(["x","y","z"]);
Then I create a table:
> this.table = new qx.ui.table.Table(this.tableModel);
with (this.table) {
// set column renderer, widths etc.
}
I add this Table to my layout and have a button that calls the following
function to load the data of the table from the database.
qx.Proto.updateTable = function(updateObject, selectedKstString)
{
var rpc = new qx.io.remote.Rpc();
rpc.setTimeout(120000);
var mycall = null;
rpc.setUrl(CONFIG["jsonRpcPath"]);
rpc.setServiceName("SERVICE");
rpc.setCrossDomain(true);
mycall = rpc.callAsync(function(result, ex, id) {
mycall = null;
if (ex == null && result != null)
{
_this.tableData = [];
for(i = 0; i < result.length; i++)
{
if(result[i][6])
{
result[i][6] = new
qx.util.format.DateFormat('yyyy-MM-dd').parse(result[i][6]);
}
else
{
result[i][6] = "--";
}
...
.....some more of this....
_this.tableData.push(Array(parseInt(result[i][5]..............),
}
_this.tableModel.setData(_this.tableData);
_this.table._updateStatusBar();
_this.table._updateScrollBarVisibility();
}
That is infact what I am doing. The only objects I create are the DateFormat
objects and some additional stuff.
I tried to dispose this.table or this.tableModel bevor I updated the data
but that doesnt work at all. I get some errors on loading the table or the
memory usage is already increasing.
I also think that I don`t have to dispose the Table, when I reload the table
data. Do I have to call a function to iterate throug this.tableData an
dispose every object inside bevor I add new data? Do I have to dispose every
object I create in the updateTable function?
Thanks for any help
Philipp
