Thank you for you answer Hugh,
I did a search for _focusedRow and found that qx.ui.table.pane.Pane
holds the last focused row information as well.
The information about the selected row is spread over four classes :-(
qx.ui.table.Table
qx.ui.table.selection.Manager
qx.ui.table.pane.Pane
qx.ui.table.pane.Scroller
The following code parts should reset the selection information to the
initial state:
1. qx.ui.table.Table: the constructor contains the following initial code:
this._focusedCol = 0;
this._focusedRow = 0;
2. qx.ui.table.selection.Manager: the clearSelection method call should
be sufficient.
3. qx.ui.table.pane.Pane: the _focusedCol and _focusedRow attributes are
uninitialized so we have to delete them.
4. qx.ui.table.pane.Scroller: : the _focusedCol and _focusedRow
attributes are uninitialized so we have to delete them.
I ended up with the following method for qx.ui.table.Table for the
ultimate de-selection of table rows:
clearSelection : function()
{
this._focusedCol = 0;
this._focusedRow = 0;
var scrollerArr = this._getPaneScrollerArr();
for (var i = 0; i < scrollerArr.length; i++) {
delete scrollerArr[i]._focusedRow;
delete scrollerArr[i]._focusedCol;
delete scrollerArr[i]._tablePane._focusedRow;
delete scrollerArr[i]._tablePane._focusedCol;
}
this.getSelectionModel().clearSelection();
},
