My question is related to the MVP pattern. I have a VerticalPanel in
which I add several CheckBox. The UI is build on the fly since it
depends on the user settings. The user clicks some of the checkboxes
and in my presenter I would like to know which one are selected. What
should I put in my view interface of the presenter. My current
approach is the following:
The presenter:
public interface MyView {
HasWidgets getTagsContainer();
void showTagsContainer(); // Do a setVisible in the view
HasValue<Boolean> getCheckBox(int i); // Return the ith checkbox
}
// Build the UI in the fly
HasWidgets tagsContainer = getView().getTagsContainer();
tagsContainer.clear();
for (Tag tag : currentUser.getTags()) {
tagsContainer.add(new CheckBox(tag.getTagName()));
}
getView().showTagsContainer();
The user clicks on some of the checkboxes
// Find the one which are checked
int i=0;
for(Tag tag: currentUser.getTags()) {
boolean checked = getView().getCheckBox(i).getValue();
i++;
}
What do you think of my approach? Is there a better way to achieve it?
I am learning the MVP pattern, so I try to get the best practices.
