Hello,
I'm creating a menu, and I basically need my UserInfo object already set
(based on the username) before creating the menu and doing the initWidget().
Basically I have the username, and based on this, I query the DB and get
everything else based on that username.
But I am using an RPC call for the backend part. How can I make sure that
userInfo is set before proceeding to the createMenu() and initWidget() part
?
private static UserInfo userInfo;
public UserPanel() {
container = new MaterialContainer();
container.setFontSize("1em");
setUserInfo("someUsername");
Widget mainMenu = createMenu();
initWidget(mainMenu);
}
public void setUserInfo(String username) {
DBGetUserInfoAsync rpcService = (DBGetUserInfoAsync)
GWT.create(DBGetUserInfo.class);
ServiceDefTarget target = (ServiceDefTarget) rpcService;
String moduleRelativeURL = GWT.getModuleBaseURL() + "DBGetUserInfoImpl";
target.setServiceEntryPoint(moduleRelativeURL);
rpcService.getUserInfo(username, new AsyncCallback<UserInfo>() {
@Override
public void onSuccess(UserInfo result) {
UserPanel.userInfo = result;
}
@Override
public void onFailure(Throwable caught) {
// Window.alert(caught.getMessage());
}
});
}
