Mouse Double-Click Event

tcampos

Hi there,

I have a doubt about the events that are generated by a mouse double click action since I've read on another forum that after the mouseButtonDblClick comes a second mouseButtonRelease. I'm getting only one mouseButtonRelease. Isn't it suppose to return another one after mouseButtonDblClick?

This is what i get in the following order:

mouseButtonPress;
mouseButtonRelease;
mouseButtonDblClick.

Thanks in advance.

The sequence is: press -> release -> double click (by default = press) -> release.

Are you really sure? I'm using a counter variable to count mouseButtonRelease events and each double click action with the mouse is returning only one release event...

AFAIK, this depends on the OS you are on. Mouse and keyboard events are typically processed by the OS and then send to Qt which creates the Qt events.

Of course I use the first platform I have: Windows XP ... but I could check too under linux.
You have right Gerolf it depends of the platform, however I doubt that Qt implement an extra 'press' if no 'release' is sent.

press -> release -> press (double click) [ -> press for the next ... ] breaks the invariant of press/release counts.
