Hello,
I have to implement a messaging system for my application. I want all my
conversations to be visible and the user should select one of those to open.
I'm creating a FlexTable from a List of Conversations returned to me via
RPC.
My ideea to select one conversation of all available was to link the
subject column with a normal servlet getting the id as a parameter.
But the ideea is I do not want to open another page to display the
conversation. I want to display it on the same page. I wan't to clear the
existing widget and create a new one with all the messages in the selected
conversation.
How can I do that ? Link to GWT what was clicked, in order for it to clear
the current widget and create a new one...
Or is there a better idea ? Like can it be done through RPC ?
Thanks in advance,
Andrei
DBGetAllConversationsAsync rpc = (DBGetAllConversationsAsync)
GWT.create(DBGetAllConversations.class);
ServiceDefTarget tar = (ServiceDefTarget) rpc;
String moduleURL = GWT.getModuleBaseURL() + "DBGetAllConversationsImpl";
tar.setServiceEntryPoint(moduleURL);
rpc.getAllMessages(userInfo, new AsyncCallback<List<Conversation>>() {
@Override
public void onSuccess(List<Conversation> result) {
DOM.getElementById("loading").getStyle().setDisplay(Display.NONE);
int start = 1;
for (Conversation conversation : result) {
int id = conversation.getId();
flexTable.setHTML(start, 0, String.valueOf(id));
flexTable.setHTML(start, 1, conversation.getDate());
String username = userInfo.getUsername();
String source = conversation.getSource();
String destination = conversation.getDestination();
flexTable.setHTML(start, 2, source.equals(username) ? destination : source);
flexTable.setHTML(start, 3,
"<a href=\"" + GWT.getModuleBaseURL() + "viewConversation?id=" + id + "\">"
+ conversation.getSubject() + "</a>");
flexTable.setHTML(start, 4, "0");
flexTable.setHTML(start, 5, "Unread");
start++;
}
}
@Override
public void onFailure(Throwable caught) {
...
}
});
