    <p>C++ does not offer any kind of functionality for that, unfortunately, you have to write the getters and setters manually.</p> <p>Since the language offers no kind of support for this kind of thing, there are a few rules of thumb you need follow to produce better quality code:</p> <ul> <li><p>All member variables should be non-public. If they need to be accessed, write a getter and/or setter. This allows you to easily modify how that variable is accessed later on, without too much trouble.</p></li> <li><p>Only members that are part of the interface (i.e.: which need to be visible) should have getters/setters. Don't start writing a getter/setter pair for every member in your class and call it encapsulation, 'cause it's not.</p></li> <li><p>If you need a setter or a getter for a variable, it doesn't automatically mean you need the other as well. In principle, only add something if you need it: it's easy to add new things, but it's hard to remove them once you already have code that uses that feature. </p></li> </ul> <p>In general, here's how getters and setters work in C++:</p> <pre><code>class Person { public: const std::string&amp; name() const { return name_; } void name(const std::string&amp; name) { name_ = name; } private: std::string name_; }; int main() { Person pers; pers.name("John"); std::cout &lt;&lt; pers.name(); return 0; } </code></pre> <p>A lot of people like to name those functions <code>getName()</code> and <code>setName()</code>, but I prefer to have it like this. Also remember to always make your getters <code>const</code> (eg.: at the end of <code>const std::string&amp; name() const</code>) &mdash; this will signal to the compiler that the function won't modify the <code>Person</code> object.</p> <p><strong>Edit:</strong> As you can see, in C++ getters and setter are just like any other method, there's absolutely nothing special about them.</p>

    1. COWhy would you need to expose the name? For printing? Then make the stream operator a friend. There is no need to expose name. You are creating a tight coupling to your class that you will need to maintain even if it is never required.

    2. CO@LokiAstari Just an example. Anyway, what use would the class be if I can't read anything about it (I have no getters)?

    3. COYou expose the action that can be performed on the class via methods. There is practically never a reason to expose the implementation to anything but the interface.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
