[ahmet kara]

Hi,

I am trying to develope a desktop application with gwt4air but I
coludn't make. I read wiki but not is working for me on that pages. Is
there a sample project that I can download and check?

Hi there, 

can you tell me what type of  desktop application are you trying to build ?

HTML/CSS/JS  or Flex based ? 

Thanks,

Alain

Hi nino,

Sorry I couldn't write back soon.

I went to http://code.google.com/p/gwt4air/wiki/GettingStarted and did
everything what was in there. Then I went to http://code.google.com/p/gwt4air/wiki/Notification
page and copied and pasted the sample codes to my new gwt sample
project. But I can't import the right things. For example the Button,
import com.ekambi.gwt.air.flx.client.spark.components.Button; or
import com.ekambi.gwt.air.flx.client.spark.components.Button; gives
error for the project. Sample is below.


package com.sample.client;

import com.ekambi.gwt.air.core.client.utils.notification.Notification;
import com.ekambi.gwt.air.flx.client.mx.controls.Button;

import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.event.dom.client.ClickEvent;
import com.google.gwt.event.dom.client.ClickHandler;
import com.google.gwt.user.client.ui.RootPanel;

/**
* Entry point classes define <code>onModuleLoad()</code>.
*/
public class GwtDesktopSample implements EntryPoint {

public void onModuleLoad() {
Button button = new Button("Click me");
button.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
Notification.get().displayMessage("Hello, World");
}
});
RootPanel.get().add(button);
}
}

what am I doing wrong??

Thankss...

Hello Ahmet, 

Looking at your code i see some issues here. 

Button button = new Button("Click me"); 
button.addClickHandler(new ClickHandler() { 
@Override 
public void onClick(ClickEvent event) { 
  Notification.get().displayMessage("Hello, World"); 
} 
}); 

button here is a regular gwt button. not the  com.ekambi.gwt.air.flx.client.mx.controls.Button.

The mxButton  class only provide a static method to create a button. Button b = Button.newInstance("Click Me");

Actually your code does not use any Flex api.

If you want to use  the flex module 

please use this wiki page instead : http://code.google.com/p/gwt4air/wiki/AirFlexSetup

Try remove the import  statements and the code should work. In the mean time i ll test it when i got home and let u know if it works for me.

Cheers,

Alain

Hi Alain,

Thanks for quick reply, I tried removing import but I got errors.

Line 27: The import com.ekambi.gwt.web cannot be resolved
Line 44: ClassUtil cannot be resolved
