How to call a function.

[Tyler1234]

I need to know how to call a function from the function main. the function I want to call can be anywhere it can be put, I just want it to work!

This is C / C++ standard.
What exactly do you try to do?

If you want to call a function, call it. If you want to call a method, call it onthe object.

I am using c++
just call the function from main so the function runs soon as the program starts.

could you please give me an example.

As Qt is just C++, maybe you should read up how to program C++ before you dip your feet into the Qt libraries. Or learn them concurrently (no pun intended).

"This":http://www.cplusplus.com/ website has some great C++ tutorials.

The Qt examples that are packaged with the libraries are another great reference. They should be right in your Qt install directory under your Qt version.

I do know c++ but I am verry new to Qt

Are you saying it is the same as c++?

[giesbert]

Qt is just a C++ framework.
If you know C++, you know how to call a function.

What exactly do0 you want to achieve with this?

[Tyler1234]

Ok, thank you

To run some code when the program launches.

Write the function call in main() ... ?

Are you talking about a specific function? Or one from Qt?

Like Gerolf says this is basic C/C++, if you wanted to call a function from main it would be:

@
int main()
{
myFunc();
return 0;
}
@

But that has absolutely nothing to do with Qt.
