Using the Qt5 connecy syntax

[bnosam]

When I try to use the newer syntax:

connect(ui->actionOpen_Script, &QAction::triggered(), OpenScript);

connect(ui->actionOpen_Script, &QAction::triggered(), OpenScript);

To copy to clipboard, switch view to plain text mode 

or

connect(ui->actionOpen_Script, &QAction::triggered(), &MainWindow::OpenScript);

connect(ui->actionOpen_Script, &QAction::triggered(), &MainWindow::OpenScript);

To copy to clipboard, switch view to plain text mode 

I get errors:

error: C2352: 'QAction::triggered' : illegal call of non-static member function

error: C2352: 'QAction::triggered' : illegal call of non-static member function

To copy to clipboard, switch view to plain text mode 

What's going on?

What's going on?

Remove the parens like this:

connect(ui->actionOpen_Script, &QAction::triggered, &MainWindow::OpenScript);

connect(ui->actionOpen_Script, &QAction::triggered, &MainWindow::OpenScript);

To copy to clipboard, switch view to plain text mode 

Hope that helps.

I get this error now:

To copy to clipboard, switch view to plain text mode 

Solution:

connect(ui->actionOpen_Script, &QAction::triggered, this, &MainWindow::OpenScript);

connect(ui->actionOpen_Script, &QAction::triggered, this, &MainWindow::OpenScript);

To copy to clipboard, switch view to plain text mode 

That fixed it.

Glad you got it to work. I was focused on the problem at hand and didn't notice you were missing the object for the slot...
