Why is this program not working?
I am not sure how you expect us to know: you have not told us what you expect it to do, or in what way it is "not working."

Attempting to create a directory with no name is unlikely to be useful. Providing a name is going to do nothing.

i when clicked "Create Dir" button, then i write a name, folder not created :(

[BalaQT]

if(!name.isEmpty())
return ;
model->mkdir(index,name);



if(!name.isEmpty()) this should be like this
if(name.isEmpty()).


When the name is not empty, you need to create the folder.

you need to remove the ! before name. isEmpty will return true when the string is empty.


hope it helps,
