Hello,
Programmatic change of selection state of node in TreeVirtual does not
select the appropriate row in the table. The following patch can eliminate
the problem.
qx.Class.patch(qx.ui.treevirtual.SimpleTreeDataModel,
qx.Mixin.define("patch.qx.ui.treevirtual.SimpleTreeDataModel",
{
members :
{
setState : function(nodeReference, attributes)
{
var nodeId, node;
if (typeof(nodeReference) == "object")
{
node = nodeReference;
nodeId = node.nodeId;
}
else if (typeof(nodeReference) == "number")
{
nodeId = nodeReference;
node = this._nodeArr[nodeId];
}
else
{
throw new Error("Expected node object or node
id");
}
for (var attribute in attributes)
{
// Do any attribute-specific processing
switch(attribute)
{
case "bSelected":
var nRowIndex =
this.getRowFromNodeId(nodeId);
var selectionModel =
this.getTree().getSelectionModel();
var bChangeSelection = (typeof(nRowIndex)
=== "number"
&& this.getTree().getSelectionMode() !=
qx.ui.treevirtual.TreeVirtual.SelectionMode.NONE);
// The selected state is changing. Keep track
of what is selected
if (attributes[attribute])
{
this._selections[nodeId] = true;
// Add selection range for node
if (bChangeSelection && !
selectionModel.isSelectedIndex(nRowIndex)) {
selectionModel.setSelectionInterval(nRowIndex, nRowIndex);
}
}
else
{
delete this._selections[nodeId];
// Delete selection range for node
if (bChangeSelection &&
selectionModel.isSelectedIndex(nRowIndex)) {
selectionModel.removeSelectionInterval(nRowIndex, nRowIndex);
}
}
break;
case "bOpened":
// Don't do anything if the requested state is
the same as the
// current state.
if (attributes[attribute] == node.bOpened)
{
break;
}
// Get the tree to which this data model is
attached
var tree = this.__tree;
// Are we opening or closing?
if (node.bOpened)
{
// We're closing. If there are listeners,
generate a treeClose
// event.
tree.createDispatchDataEvent("treeClose",
node);
}
else
{
// We're opening. Are there any children?
if (node.children.length > 0)
{
// Yup. If there any listeners, generate
a "treeOpenWithContent"
// event.
tree.createDispatchDataEvent("treeOpenWithContent", node);
}
else
{
// No children. If there are listeners,
generate a
// "treeOpenWhileEmpty" event.
tree.createDispatchDataEvent("treeOpenWhileEmpty", node);
}
}
// Event handler may have modified the opened
state. Check before
// toggling.
if (!node.bHideOpenClose)
{
// It's still boolean. Toggle the state
node.bOpened = !node.bOpened;
// Clear the old selections in the tree
tree.getSelectionModel()._clearSelection();
}
// Re-render the row data since formerly
visible rows may now be
// invisible, or vice versa.
this.setData();
break;
default:
// no attribute-specific processing required
break;
}
// Set the new attribute value
node[attribute] = attributes[attribute];
}
}
}
})
);
Best regards,
Denis
