I generally create custom Dialogs as their own uibinders and then
instantiate them from elsewhere. So I might use the code below, and
display it with "new MyDialog().center();"
Is this best practice? I'm not sure. I think there are some who hold
to the idea that you should let your dialog's content be its own
UiBinder, but that is not precluded by the strategy below. It's the
way we do things at my organization.
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder"
xmlns:g="urn:import:com.google.gwt.user.client.ui">
<g:DialogBox modal="true">
<g:caption>Dialog!</g:caption>
<g:HTMLPanel>
<g:Button ui:field="close">Close</g:Button>
</g:HTMLPanel>
</g:DialogBox>
</ui:UiBinder>
public class MyDialog {
private static MyDialogUiBinder uiBinder =
GWT.create(MyDialogUiBinder.class);
interface MyDialogUiBinder extends UiBinder<Widget, MyDialog> {}
DialogBox box;
public MyDialog() {
box = (DialogBox) uiBinder.createAndBindUi(this);
}
public void center() { box.center(); }
@UiHandler("close") void onClose(ClickEvent event) { box.hide(); }
}
