Connecting a function to a tab in Wt

Vote count:

I am using the Wt library to write in C++ a website. I would like to use tabs on that website. To do so I use the WTabWidget.

In the documentation they make a tab and link each tab to a function :

Wt::WTabWidget *examples = new Wt::WTabWidget(this);
examples->addTab(helloWorldExample(), "Hello World");
examples->addTab(chartExample(), "Charts");
examples->addTab(new Wt::WText("A WText"), "WText");

Based on that I wrote this :

WTabWidget *myTab = new WTabWidget(); myTab->addTab(test(), "Test Tab");

But my compiler tells me :

error: cannot initialize a parameter of type 'Wt::WWidget *' with an rvalue of type 'void'

My "test" function has return type void. It's logic an rvalue of type void cannot be assigned to a parameter of type "WWidget*".

But if they show that example in the documentation, why can't I do it?

that : examples->addTab(chartExample(), "Charts");

Thanks for your help!
