Qt no such slot base class

By Guest

If I try to connect the testSendQuuid(QUuid) signal to the slot, I get no such signal and no such slot as well. I cannot for the life of me figure out why Qt is denying the existence of a slot that is most definitely there!

The QLayout class is the base class of geometry managers. This is an abstract base class inherited by the concrete classes QBoxLayout, QGridLayout, QFormLayout, and QStackedLayout. For users of QLayout subclasses or of QMainWindow there is seldom any need to use the basic functions provided by QLayout, such as setSizeConstraint() or setMenuBar(). QHeaderView Class Reference - het.as.utexas.edu The QHeaderView class provides a header row or header column for item views. A QHeaderView displays the headers used in item views such as the QTableView and QTreeView classes. It takes the place of Qt3's QHeader class previously used for the same purpose, but uses the Qt's model/view architecture for consistency with the item view classes. Qt-Generator for YAKINDU SCT / Wiki / Home - SourceForge Add a new C++ class which derive the abstract class generated from the Qt generator. Implement this by deriving the base class with public visibility otherwise you cannot connect the Qt's signals and slots to the statemachine. Since the generated class does not implement any operation you have to do this inside this class. Slots — Vue.js

Pure virtual class with singals and slots. ... Either don't base on QObject, but use Q_SLOTS and Q_SIGNALS macros (I'm not sure if that would work, though), or make IGui into a QMainWindow, and inherit from it. ... I had a problem with a class like that, that worked using QT 4.7.something (no complier warning or error) and when updating to 4.8 ...

Salut à tous ! Je me penche actuellement sur le tuto de M@teo21 sur le QT et j'en suis arrivé au TP du ClassGenerator. Je suis heurté à un problème et même après quelques recherches sur Google (toutes infructueuses) et après avoir regardé la correction de M@teo21, le problème est toujours sans solution.

QPushButton Class | Qt 4.8 Small, typically square buttons that change the state of the window rather than performing an action (such as the buttons in the top-right corner of the QFileDialog) are not command buttons, but tool buttons. Qt provides a special class (QToolButton) for these buttons. Qt for Beginners - Qt Wiki

QTranslator Class | Qt Core 5.12.2

The class in it self contains one constructor and two slots. The constructor parameters are the standard Qt parameters - a parent and a name. The parent is used by the Qt memory management (and more) and the name is used when debugging. These parameters will be passed onto the base class in the implementation.
