Hello,
First of all all widgets are not copyable so you can't put
them to STL containers!
The simplest way is to call form::attach(...) and add them dynamically
to the form as pointers (ownership is transferred to the form object)
Then you can render them as
<% foreach box in my_form.list_of_pointers_to_checkboxes %>
<ul>
<% item %>
<li><% form as_space *box %></li>
<% end %>
</ul>
<% end %>
Each one independently or you can use a sub form that you add
all dynamic widgets to it and render them in one command
<% from as_ul my_form.chckboxes_subform %>
For example:
class my_form : public cppcms::form{
cppcms::form checkboxes; // Subform
std::vector<cppcms::widgets::checkox *> boxes;
my_form()
{
add(checkboxes); // register to parent
for(int i=0;i<n;i++) {
cppcms::widgets::checkox *box = new cppcms::widgets::checkox();
checkboxes.attach(box); // transfer ownership and register to parent
box->message(...)
boxes.push_back(box);
}
}
}
Rendering
<% from as_ul my_form.checkboxes %>
Take a look on this as example:
