[Qt-interest] right mouse button and MacOS

[Robert Hairgrove]

On Windows and Linux, the right mouse button is often used to open a 
context menu. I never used a Mac, but heard that the mouse has only one 
button.

Is this still true, or is it a thing of the past? How does Qt implement 
context menus on Mac if there is only one button? i.e., how is it 
usually done on Mac with native applications?

Thanks!
