Hi Veronika,
welcome to the community.
I have no idea, why you have problems with your custom renderer and the remote
table model. I would try to test only the remote table model implementation and
remove the custom renderer. This should help to detect which implementation
doesn't work.
Now to you tree question. It is not clear for me what exactly is your problem
with the virtual three. Normally you use a change selection for triggering the
logic and not a click event. Maybe you can provide a running Playground
example. This could help to see what you are try to achieve and what's the
current problem.
Thanks,
Chris

Betreff: [qooxdoo-devel] RowRenderer in remote table model
Hello,
firstly i want to thank you for such nice framework and great work!
I'm newbie in qooxdoo and just learning it. I have two questions:
1. I'm trying to use remote table model and custom RowRenderer, which is based
on data from table. I wrote example with table, which model was Simple and
everything worked fine! However, when i changed table model from Simple to
Remote, Rowrenderer stopped to work normally. On table load it returns error:
057196 qx.io.remote.RequestQueue[287-0]: Request qx.io.remote.Request[831-0]
handler _oncompleted threw an error: TypeError: rowInfo.rowData is null
But in the same time it marks rows in needed color and returns error showed
above. As i understood the problem could be in fact, what getrowcount at remote
tablemodel don't get all rows, just cached ones or even 0 in new releases...
How to resolve this? My code is:
---> table model:
var tableModel = new app.RemoteDataModel(folder);
tableModel.setColumns([qx.locale.Manager.tr<http://qx.locale.Manager.tr>("Status"),
qx.locale.Manager.tr<http://qx.locale.Manager.tr>("Surname"),
qx.locale.Manager.tr<http://qx.locale.Manager.tr>("Name")], [ "status",
"surname", "name"]);
var table = new qx.ui.table.Table(tableModel);
table.setShowCellFocusIndicator(false);
table.setHeight(300);
table.setDataRowRenderer(new app.InvoiceListRowRender(table));
--> app.InvoiceListRowRender(table) is taken from previous examples in this
mailing list
qx.Class.define("app.InvoiceListRowRender", {
extend : qx.ui.table.rowrenderer.Default,
members : {
// overridden
updateDataRowElement : function(rowInfo, rowElem)
{
this.base(arguments, rowInfo, rowElem);
var style = rowElem.style;
if (!(rowInfo.focusedRow && this.getHighlightFocusRow()) &&
!rowInfo.selected) {
style.backgroundColor = (rowInfo.rowData.status > 0) ?
this._colors.bgcolEven : this._colors.bgcolOdd;
}
},
// overridden
createRowStyle : function(rowInfo)
{
var rowStyle = [];
rowStyle.push(";");
rowStyle.push(this.__fontStyleString);
rowStyle.push("background-color:");
if (rowInfo.focusedRow && this.getHighlightFocusRow())
{
rowStyle.push(rowInfo.selected ? this._colors.bgcolFocusedSelected :
this._colors.bgcolFocused);
}
else
{
if (rowInfo.selected)
{
rowStyle.push(this._colors.bgcolSelected);
}
else
{
rowStyle.push((rowInfo.rowData.status > 0) ? this._colors.bgcolEven :
this._colors.bgcolOdd);
}
}
rowStyle.push(';color:');
rowStyle.push(rowInfo.selected ? this._colors.colSelected :
this._colors.colNormal);
rowStyle.push(';border-bottom: 1px solid ', this._colors.horLine);
return rowStyle.join("");
}
}
});
How to avoid this error: rowInfo.rowData is null in remote table case?
2. question is related to virtual tree and click event
I have menu, which is based on virtual tree and when user clicks on folder
event returns value to function, which creates a widget and adds it to the main
Dock layout. However when user clicks on other folder in virtual tree widget is
not recreated in layout, but added. How to recreate widget? The best example of
this situation is qooxdoo demobrowser with tree on left side and test on the
right side. Could you please provide simple code example to achieve this
functionality?
Thanks!
Best Regards,
Victoria
