Enter points coordinates and generate it by pushing button

Hello!
I'm beginner and that's why I need your help((
I made dialog window like this and I want generate inputting data, but I don't know how...
I think about using QVector3D, can you help me please?
-
@Christin You can use QVector3D, or you can use 3 variables: x, y, z.
Where exactly do you need help? -
@jsulm I don't know how to use QVector3D))) I read some documentation and came across QVector3D and since I'm beginner I'm not good at coding
@Christin But what exactly is the problem? You create an instance of QVector3D and set x,y,z using https://doc.qt.io/qt-5/qvector3d.html#setX
https://doc.qt.io/qt-5/qvector3d.html#setY
https://doc.qt.io/qt-5/qvector3d.html#setZ -

@jsulm I think creating is the problem, I don't understand how I must do it... I use EditLines for inputting data, then via QString I get it like text, but I need to make coordinates array
-
From your choice of using
QEditTextyou can convert digits typed in into numbers via QString::toInt(). -
If you use instead
QSpinBoxes, you get the numbers done for you in QSpinBox::value().
Then you put those numbers into some array as required.

@JonB thank you so much for your help!! I'll try... But using this way will project understand that it is coordinates?

In the nicest way, you need to do some reading/understanding about basic programming: "and since I'm beginner I'm not good at coding". This site is not a tutorial for learning to program, you need to do that for yourself or go to suitable forums.
Computer programs don't "understand" anything (even less than e.g. football supporters/babies/world leaders). You will (have to do whatever to) use the numbers you get as coordinates --- or for that matter as money or apples --- from the library calls you make/whatever you pass the numbers to. The answer is "yes, you will be able to use those numbers as coordinates".
