Hi David,
Out of curiosity I tried that one and it works. Actually you shud first set
the widget of the tree item as text box, then call the setSelected(true) for
the tree item and then set the focus to the text box. This works in FF.
*package* litty.test.client;
*import* com.google.gwt.core.client.EntryPoint;
*import* com.google.gwt.user.client.Window;
*import* com.google.gwt.user.client.ui.FocusListenerAdapter;
*import* com.google.gwt.user.client.ui.KeyboardListenerAdapter;
*import* com.google.gwt.user.client.ui.RootPanel;
*import* com.google.gwt.user.client.ui.TextBox;
*import* com.google.gwt.user.client.ui.Tree;
*import* com.google.gwt.user.client.ui.TreeItem;
*import* com.google.gwt.user.client.ui.TreeListener;
*import* com.google.gwt.user.client.ui.Widget;
*public* *class* Home *implements* EntryPoint, TreeListener {
Tree homeTree;
*public* *void* onModuleLoad() {
init();
}
*private* *void* init() {
homeTree = *new* Tree();
TreeItem root1 = *new* TreeItem("ABC");
root1.addItem("ABC1");
root1.addItem("ABC2");
root1.addItem("ABC3");
TreeItem root2 = *new* TreeItem("DEF");
root2.addItem("DEF1");
root2.addItem("DEF2");
TreeItem root3 = *new* TreeItem("EFG");
root3.addItem("EFG1");
root3.addItem("EFG2");
root3.addItem("EFG3");
homeTree.addItem(root1);
homeTree.addItem(root2);
homeTree.addItem(root3);
homeTree.addTreeListener(*this*);
RootPanel.*get*().add(homeTree);
}
*public* *void* onTreeItemSelected(*final* TreeItem item) {
*if* (!(item.getWidget() != *null* && item.getWidget() *
instanceof* TextBox)) {
*final* String originalText = item.getText();
*final* TextBox box = *new* TextBox();
box.setText(originalText);
item.setWidget(box);
item.setSelected(*true*);
box.selectAll();
box.setFocus(*true*);
box.addKeyboardListener(*new* KeyboardListenerAdapter() {
*public* *void* onKeyPress(Widget sender, *char*keyCode,
*int* modifiers) {
*if* (keyCode == *KEY_ENTER*) {
item.setText(box.getText());
} *else* *if* (keyCode == *KEY_ESCAPE*) {
item.setText(originalText);
}
}
});
box.addFocusListener(*new* FocusListenerAdapter() {
*public* *void* onLostFocus(Widget sender) {
Window.*alert*("Focus lost");
item.setText(box.getText());
}
});
}
}
*public* *void* onTreeItemStateChanged(TreeItem item) {
// *TODO* Auto-generated method stub
}
}
Hope this helps.
