Hello -
I am working on GwtExt sample codes (POC) so that I can use it in one
of my projects. I have written a GwtExtTest.java file which has code
as below :- (This code has been picked from GWT-EXT sample codes)
public class GwtExtTest implements EntryPoint
{
public void onModuleLoad()
{
LayoutDialog dialog = new LayoutDialog(new LayoutDialogConfig()
{
{
setTitle("Basic Dialog");
setModal(true);
setWidth(500);
setHeight(300);
setShadow(true);
setMinHeight(300);
setMinHeight(300);
}
}, new LayoutRegionConfig());
//first way to add button
Button saveBtn = dialog.addButton("Submit");
saveBtn.disable();
//another way to add button
dialog.addButton(new Button("Cancel", new ButtonConfig() {
{
setText("Cancel");
/*
setButtonListener(new ButtonListenerAdapter() {
public void onClick(Button button, EventObject e) {
dialog.hide();
}
});
*/
}
}));
//add content to the center region
BorderLayout layout = dialog.getLayout();
ContentPanel contentPanel = new ContentPanel();
contentPanel.add(new HTML("<h1>Hello World!!</h1>"));
layout.add(contentPanel);
Button button = new Button("Hello World");
/*
button.addButtonListener(new ButtonListenerAdapter() {
public void onClick(Button button, EventObject e) {
dialog.show(button.getEl());
}
});
*/
}
}
For some reason, when I try to execute this code it gives me an error
message as below :-
[ERROR] Unable to load module entry point class

Can anyone help me with this problem.
