Determining that Num Lock is on

[LepaBrena]

Is there a way to determine that Num Lock is on?

Install an event filter or monitor key events and check for Qt:: Key_NumLock. This will only work when your app or a widget within it has the input focus. Most likely if the user presses the NumLock key when a different app has input focus, your app won't be notified. I do not know if there is a way to determine a priori if the NumLock key is pressed during a normal key event.

You can do this with the help of native system functions. Ask uncle Google.

I need to check it before user presses any numpad key.

I ask uncle Google before any post. I did not find the answer for this, so I asked.
Can you write me link where I can find solution?

I'll be malicious: somewhere they should learn how to ask Google :p

You are right. Need some instructions for google search and for writing posts too :)
This is solution for win and linux, but I'm looking something for android (working platform: win).
