Hi again :)
i try to make some sort of model, view , controler with a login
window,
but i have a little problem.
In my Application.js i create an instance of my Controler like this :
var loginContrl = new firstapp.controler.loginControler();
loginContrl.showLogin();
The source of the Controler looks like :
qx.Class.define("firstapp.controler.loginControler",
{
extend : qx.core.Object,
construct : function()
{
this.loginWindow = new firstapp.ui.loginBox("LoginWindow",null);
},
members :
{
loginWindow : null,
performLogin : function()
{
alert("blub");
},
showLogin : function()
{
this.loginWindow.open();
this.loginWindow.addLoginListener(this.performLogin);
}
}
});
Additionally i have a loginWindow class, that looks like this :
/*
************************************************************************
Copyright:
License:
Authors:
************************************************************************ */
/*
************************************************************************
#asset(firstapp/*)
************************************************************************ */
/**
* This is the main application class of your custom application
"firstapp"
*/
qx.Class.define("firstapp.ui.loginBox",
{
extend : qx.ui.window.Window,
/*
*****************************************************************************
MEMBERS
*****************************************************************************
*/
construct : function(name,icon)
{
this.base(arguments,name,icon);
this.set
({
modal : true,
showMinimize : false,
showMaximize : false,
allowMaximize : false,
allowClose : false
});
this.addContent();
},
members :
{
loginButton : null,
loginListener : null,
/**
* This method contains the initial application code and gets
called
* during startup of the application
*/
addContent : function()
{
var windowLayout = new qx.ui.layout.VBox(10);
this.setLayout(windowLayout);
this.setMinWidth(300);
var loginField = new qx.ui.form.TextField("Enter
Login").set({width: 260});
var passField = new qx.ui.form.PasswordField("Enter
Passw").set({width : 260});
loginButton = new qx.ui.form.Button("Login");
this.add(loginField);
this.add(passField);
this.add(loginButton);
this.addListenerOnce("resize", this.center, this);
},
addLoginListener : function (listener)
{
this.loginListener = listener;
this.loginButton.addListener("execute",this.loginListener());
}
}
});
When the loginControler is instantiated, it creates an instance of
the
login window, registers a listener for the button and then it opens
the
window. But the registered listener is not called, when i press the
button. Nothing happens ? Is it not allowed to hand over a function
pointer from another class as listener ?
Thank you
Tom
