TreeGrid is draw?

[sonnerdev]

Hi guys


At startup, my application do somenthing like this:
...
TreeGrid treeGrid = new TreeGrid();
treeGrid.setDataSource(DataSource.getInstance());
treeGrid.fetchData();
selectNode(presenterName);
....


public void selectNode(String presenterName) {
Tree tree = menuTreeGrid.getData();
TreeNode treeNode = (TreeNode) tree.find("presenterName",
presenterName);
if(treeNode != null) {
menuTreeGrid.selectSingleRecord(treeNode);
}
}

That code never works at startup because treeNode is null. Looks like the treeGrid its not draw yet or something like that. If I create a simple test button that calls selectNode(...) its works. The tree.find(...) returns a valid treeNode.

I tried use this:

treeGrid.addDataArrivedHandler(new DataArrivedHandler() {
public void onDataArrived(DataArrivedEvent event) {
//...
selectNode(...);
}
}

but dit not work too.

So, how the hell I know the time to call selectNode(...) ?

you answered your question in the subject line alone: addDrawHandler()
