Example text

Emit is a Qt macro that will immediately trigger the connected slot with what we passed in a parameter. As we said earlier, removed(Task* this) has no function body, its purpose is to notify the registered slot of an event. Lambdas are a great addition to C++. They offer a very practical way of defining short functions in your code. Technically, a lambda is the construction of a closure capable of capturing variables in its scope. params: This is the function parameters type list that can be passed to the lambda scope.

Using a QDialog We deserve something better than an untitled task. The user needs to define its name when it's created. The easiest path would be to display a dialog where the user can input the task name. Fortunately Qt offers us a very configurable dialog that fits perfectly in addTask(): #include ... append(task); ui->tasksLayout->addWidget(task); } } The QinputDialog::getText function is a static blocking function that displays the dialog. When the user validates/cancels the dialog, the code continues.
