All you really need is a panel, any basic type would do. And
dynamically add contacts to this pannel as hyper text or buttons.
Not sure you really need a stack panel for this.
Example:
private VerticalPanel myVerticalPanel = new VerticalPanel();
protected ArrayList<Button> myButtons = new ArrayList<Button>();
ClickHandler myButtonHandler = new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
if (button != null && button instanceof Button) {
String mytitle = button.getTitle();
// Use the title that has the name in it to do what you
need to do
} else {
//TODO: Some error
}
}
};
// Load the buttons into the panel
public void load();
myVerticalPanel.clear();
for (ButtonBase button : myButtons) {
myVerticalPanel.add(button);
}
}
// Add a button to the list
public void add(String name) {
Button myButton = new Button(name, myButtonHandler);
myButton.setTitle(name);
myButtons.add(myButton);
load();
}
The above simple example is an example. You can add and remove items
from the veritical panel, thus you would not have
to reload the complete panel everytime.
Hope this helps
private VerticalPanel myVerticalPanel = new VerticalPanel();
