Re: Access specific link from dynamically build FlexTable

I think that is different from the answer, but I thought that I if to hint.

I, using cookies, we implement this.

To set the cookie in the message, we try to show the message to people who do not have the message cookie.

public static Panel createInfomation(){

final VerticalPanel p_vp = new VerticalPanel();

final List<M_RpcInfo> p_not_read= new ArrayList<M_RpcInfo>();

final Label p_status = new Label("確認中");

p_vp.add(p_status);

final ServiceCommonAsync greetingService = GWT.create(ServiceCommon.class);

RpcCommuObj prc = RpcCommuObj.createObjListInfo(null, 1,new String[]{}, new String[]{}, "", 5, "info", false);

greetingService.getDaialogInfomationListForPanel(prc, new AsyncCallback<List<M_RpcInfo>>(){

@Override

public void onFailure(Throwable caught) {

p_status.setText(caught.getMessage());

}

@Override

public void onSuccess(final List<M_RpcInfo> result) {

final StringBuffer cnt=new StringBuffer();

cnt.append("0");

for(int i=0;i<result.size();i++){

String isRead=Cookies.getCookie("IS_READE_ID_"+result.get(i).getValue("id")+"_"+result.get(i).getValue("value01"));

if(isRead==null){

int p_cnt =Integer.valueOf(cnt.toString()).intValue()+1;

cnt.delete(0, cnt.length());

cnt.append(""+p_cnt);

p_not_read.add(result.get(i));

}

}

p_vp.remove(p_status);

HorizontalPanel p_hp2 = new HorizontalPanel();

Button p_btn = new Button("お知らせを表示");

HTML p_info= new HTML("未読<font style=\"color:red;\">" +cnt +"</font>件");

p_hp2.add(p_btn);

p_hp2.add(p_info);

p_vp.add(p_hp2);

p_btn.addClickHandler(new ClickHandler(){

@Override

public void onClick(ClickEvent event) {

final VerticalPanel p_vp_info = new VerticalPanel();

DialogBox p_dialog =KutTool.createDialog(p_vp_info);

if(Integer.valueOf(cnt.toString()).intValue()>0){

//p_vp.add(new Label("未読のお知らせが "+cnt +" 件あります"));

for(int i=0;i<p_not_read.size();i++){

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) {

...

}

});
