Hejsan,
I am building dynamic Tree Widget. First Level I done with no problem
so it look like:
+ Atletics
+ Ice Hockey
+ Chess
+ Footbal
+ Golf
Functionality must be like when you click on sport must roll up/show
off list of countries like:
+ Atletics
+ Ice Hockey
+ Canada
+ USA
+ Russia
+ Chess
+ Footbal
+ Golf
and when click to some country then show off League like
+ Atletics
+ Ice Hockey
+ Canada
+ Tournaments
+ Extra league
+ 1.league
+ 2.league
+ USA
+ Russia
+ Chess
+ Footbal
+ Golf
PROBLEM is that I need get level of selected TreeItem to for each
different level will fire up different query so for example for
selected Ice Hockey need get information that it's 1 level of tree so
use databases select to find out all countries for "Ice hockey".
When click to "Canada" TreeItem, it's level 2 I call select to find
out all leagues level for "Canada".
I create handler for Tree like:
// Add a handler that automatically generates some children
statTree.addOpenHandler(new OpenHandler<TreeItem>() {
public void onOpen(OpenEvent<TreeItem> event) {
// tree item that was clicked
TreeItem itemSelected = event.getTarget();
if (itemSelected.getChildCount() == 1) {
// Close item immediately
itemSelected.setState(false, false);
// Add a random number of children to
the item
String itemText =
itemSelected.getText();
// request to database according
selected tree item level
// dummy data
for (int i = 0; i < numChildren; i++) {
// tree item to be added
TreeItem childDescendant =
itemSelected
.addItem(itemText + "." + i);
System.out.println("\ncildDescendant index: "
+
itemSelected.getChildIndex(childDescendant));
childDescendant.addItem("");
}
// Remove the temporary item when we
finish loading
itemSelected.getChild(0).remove();
// Reopen the item
itemSelected.setState(true, false);
}
}
});
Please help me some one I'll do appreciate it.
Thank you
