Hi guys! I solved a trouble a I need to broadcast it!!
First you need to put a <div tag> with a ID like this in your html
code
<div id="main">
</div>
Second in your ImageViewer.java you have to add a VerticalPanel (you
can use GWT designer it is very easy) see the code below
public class ImageViewer implements EntryPoint {
private VerticalPanel VLayout;
private TabPanel tabPanel;
private Button btnNewButton;
public void onModuleLoad() {
RootPanel rootPanel = RootPanel.get();
rootPanel.setSize("800", "600");
rootPanel.add(getVLayout(), 156, 52);
THIS IS THE MAGIC I AM PUTING ALL MY VLayout INTO MY
HTML DIV
RootPanel.get("main").add(VLayout);
}
private VerticalPanel getVLayout() {
if (VLayout == null) {
VLayout = new VerticalPanel();
VLayout.setSize("340px", "221px");
VLayout.add(getTabPanel());
}
return VLayout;
}
private TabPanel getTabPanel() {
if (tabPanel == null) {
tabPanel = new TabPanel();
tabPanel.setSize("287px", "169px");
tabPanel.add(getBtnNewButton(), "New tab", false);
}
return tabPanel;
}
private Button getBtnNewButton() {
if (btnNewButton == null) {
btnNewButton = new Button("New button");
btnNewButton.setSize("104px", "33px");
}
return btnNewButton;
}
}
I am a begginer but it was very hard to me discovery that!! Thank you
every one guys
