Different of deviceWidth() between QScreen in Qt4 and Qt5

victor wang

I have an example that using function "deviceWidth".
This example is develop on qt4.
But now i'm using qt5 to develop it.
And i got some problem!
I didn't know is there any similar function which is in qt5 and same as the function "deviceWidth()" at qt4.
Please help!

I'll be as vague in my answer as you are in your error description and answer:

Yes

@victor-wang said in the different of deviceWidth() between Qscreen in qt5 and in qt4:

And i got some problem!

That is not much to go by, I could guess... but that that doesn't help me nor you.

@victor-wang "And i got some problem!", "Please help!" - I would like to help you, but I can't as you did not say what the problem is ("And i got some problem" - is not a problem description).

Hi, as you can see from the other responses
the wording of the post is not optimal :)

I assume you mean.

In the Qt4 sample, the function deviceWidth() is used.
What function can i use instead in Qt5 ?

To that, i think , this will give the same info

QScreen *screen = QGuiApplication::primaryScreen();
QRect  screenGeometry = screen->geometry();
int height = screenGeometry.height();
int width = screenGeometry.width();
