My understanding is faulty.
The "final" keword gave me grief so I moved the button and textbox
definitions "outside". I am only seeing "change" BrowserEvents being
triggered. I am using GWT 2.0, eclipse 3.5 with the GWT plugin. I am
on the most recent or a very recent Ubuntu box and am displaying this
test in a firefox 3.5.7 browser.
So, the app starts with an empty textbox and disabled button. I use
the mouse to select some text and then either I:
- move the mouse to the textbox and just paste or
- move the mouse to the textbox, click the textbox and then paste
In either case onBrowserEvent is not triggered... as far as I can tell.
After the paste, if I click outside the textbox then I get a "change"
event alert message from onBrowserEvent.
The new test is:
public class Test implements EntryPoint {
Button sendButton = new Button("Send");
TextBox nameField = null;
public void onModuleLoad() {
nameField = new TextBox() {
public void onBrowserEvent(Event event)
{
Window.alert(event.getType());
if (event.getTypeInt() == Event.ONPASTE) {
if (nameField.getValue().equals("")) {
sendButton.setEnabled(false);
} else {
sendButton.setEnabled(true);
}
}
}
};
sendButton.setEnabled(false);
nameField.addChangeHandler(new ChangeHandler(){
@Override
public void onChange(ChangeEvent event) {
if (nameField.getValue().equals("")) {
sendButton.setEnabled(false);
} else {
sendButton.setEnabled(true);
}
}
});
RootPanel.get("nameFieldContainer").add(nameField);
RootPanel.get("sendButtonContainer").add(sendButton);
}
}
