open a folder with Qt

[Alex22]

Hi, sorry i searched this in net but i fund nothing! how can i open a folder in Qt?
for example in this path:"c:\newfolder" I want to open "newfolder" folder by clicking a PushButton.

Do you want to open the folder in the system's file manager? If so, QDesktopServices::openUrl() looks promising.

this is exactly that i want. last question: i need also if "newfolder", in path "c:\newfolder", is not exist then first create "newfolder" and then open it and if it is exist, only open it.
thanks for any help

Have a look at the QDir class. It has a method that creates a path.

@yeye_olive, Thanks
I fund this:

QDir("newfolder").exists();
 
//To create "newfolder"
QDir().mkdir("newfolder");

QDir("newfolder").exists();

//To create "newfolder"
QDir().mkdir("newfolder");

To copy to clipboard, switch view to plain text mode

I hope you understand that your "solution" only works if you want to examine or create something in your current working directory. The QDir() constructor with no arguments returns a QDir instance pointing to the current working directory.
