how to trigger context menu actions

[flashburn]

I manually added the following menu to my QTableWidget.

Here is what I have:

12115

Part of the code was setup using Qt Designer and I'm modifying it slightly in my code.

Here is the code that I've added to have a context menu:

self.group1RegistersTableWidget.addAction(self.act ionReadRegister)
self.group1RegistersTableWidget.addAction(self.act ionWriteRegister)
self.actionSeparator.setSeparator(True)
self.actionSeparator.setText("")
self.group1RegistersTableWidget.addAction(self.act ionSeparator)
self.group1RegistersTableWidget.addAction(self.act ionBinRegisterFormat)
self.group1RegistersTableWidget.addAction(self.act ionDecRegisterFormat)
self.group1RegistersTableWidget.addAction(self.act ionHexRegisterFormat)

self.group2RegistersTableWidget.addAction(self.act ionReadRegister)
self.group2RegistersTableWidget.addAction(self.act ionWriteRegister)


and here is the code that I used

I'm somewhat new to Qt. How do I process these actions. How do I know that Read/Write/Binary/Decimal/Hexadecimal has been clicked. As far as I understand I need to connect some signal to some slot, but I can't figure out which ones. Would someone be able to help me out. I'm using `PyQt4`, but C++ code would also be fine.

Any help is appreciated.

The actions objects have a "triggered()" signal.

I am not using PyQt myself but I think connect works something like


self.actionReadRegister.triggered.connect(self.som eMethod);

Thanks. I think you got it. How did you know where to look? I wasn't able to figure it out

You look at the Qt documentation, in this case for QWidget (which is where your addAction() method is defined). You see that the argument for addAction() is an instance of a QAction class. If you look at its documentation, you'll see a list of the signals; if the class inherits from another Qt class, look at the signals and slots for the base classes as well. Not only does QAction have a triggered() signal, but it also has 3 others, plus two inherited from QObject, its base class.

It also helps to look at the Qt examples and tutorials (http://doc.qt.io/qt-5/qtexamplesandtutorials.html) where almost anything you would want to do in Qt is demonstrated, at least at a basic level, in C++ and usually QML. The documentation for Qt 4.8 is also available if you google for it.
