Trying to create a file browser in pyqt but have error with qtreewidgetitem unexpected bool

Question

I am trying to get this: a link! in my pyqt program but it isn't working I have tryed a lot and resolved a lot of errors but with this one I don't know what to do. I am just tarting with pyqt and I do not have a lot of experience with python. And is there a way to automaticly start :(def load_project_structure) when the program starts insteat of using the temp testing button?

PyQt code:

Sorry didn't copy everything `Traceback (most recent call last): File "save location", line 24, in load_project_structure` Thats everything that comes before. — Robbe, Sep 18 '19 at 09:29
if you want to run `load_project_structure()` at start then run `self.load_project_structure(parameters)` in `__init__` — furas, Sep 18 '19 at 09:31
method `load_project_structure()` in class should have `self` as first parameter to correctly assign values to other variables - `def load_project_structure(self, startpath, FileStuckture):` — furas, Sep 18 '19 at 09:35
error shows that in `QTreeWidgetItem(...)` you use wrong values - one of them has wrong type. Error als o shows you what values it can accept. Maybe because you used name `FileStuckture` in `def load_project_structure(startpath, FileStuckture):` so it creates local variable `FileStuckture` and it removes `FileStuckture` which you declared in `PyQt` - `` — furas, Sep 18 '19 at 09:38
Oke, thanks for your great and fast response. Than I need to create a other variable than FileStruckture. I did that bud how do I define it? I took tree and replaced FileStruckture with it everywhare in the script. But now there is a error that tree isn't difined. — Robbe, Sep 18 '19 at 09:49
in ___init___ i have now `self.load_project_structure(self, startpath, tree)` and I changed load_project_stucture to: `def load_project_structure(self, startpath, tree):` — Robbe, Sep 18 '19 at 09:51
you are wrong - in `__init__` you have to run function with values which it will assign to variable `startpath, tree` and use inside function, don't use variables `startpath, tree` in `__init__` because they exist only inside `load_project_structure` — furas, Sep 18 '19 at 09:52

I can't run it but I think it should be

EDIT: I added self. to self.FileStuckture and to self.load_project_structure() inside def load_project_structure()

class MyWindow(QtWidgets.QMainWindow, Ui_MainWindow):

    def __init__(self):
        QtWidgets.QMainWindow.__init__(self)
        Ui_MainWindow.__init__(self)
        self.setupUi(self)
        self.load_project_structure("D:/DemoGIPhoofdmap", self.FileStuckture)


    def load_project_structure(self, startpath, tree):
        startpath = Path(startpath)
        for element in os.listdir(startpath):
            path_info = startpath / element
            parent_itm = QTreeWidgetItem(tree, [os.path.basename(element)])
            if os.path.isdir(path_info):
                self.load_project_structure(path_info, parent_itm)
                parent_itm.setIcon(0, QIcon('assets/folder.ico'))
            else:
                parent_itm.setIcon(0, QIcon('assets/file.ico'))

You should run load_project_structure in __init__ with values "D:/DemoGIPhoofdmap" and FileStuckture

self.load_project_structure("D:/DemoGIPhoofdmap", FileStuckture)

but don't use name FileStuckture in line

def load_project_structure(self, startpath, tree):

because it declares local variable FileStuckture and removes class FileStuckture which you declared in PyQt.

Oke thanks, I am also trying to understand it a litle bit more. now I get this error when I run your code: `Traceback (most recent call last): File "D:\Windows\OneDrive\OneDrive - Campus Sint-Ursula Lier\Schooljaar 2019-2020\GIP\Software\Program\code.py", line 34, in window = MyWindow() File "D:\Windows\OneDrive\OneDrive - Campus Sint-Ursula Lier\Schooljaar 2019-2020\GIP\Software\Program\code.py", line 18, in __init__ self.load_project_structure("D:/DemoGIPhoofdmap", FileStuckture) NameError: name 'FileStuckture' is not defined` – Robbe Sep 18 '19 at 09:56
It is defined in file with XML but I don't know how later it uses it to create these objects . Maybe it is defined as part of main windows and it is `self.FileStuckture` – furas Sep 18 '19 at 10:03
@furas Yes - all the widgets in the xml ui file will automatically become attributes of the object passed to `setupUi` in `__init__` (i.e. `self`, in this particular case). The attribute names are taken from the names defined in the ui file. So the tree-widget will be accessible as `self.FileStuckture`. This means the second argument of `load_project_structure` isn't needed - you can just replace all usages of `tree` with `self.FileStuckture`. (Of course, it would also help if the OP used more pythonic names in the ui file - but that's another story). – ekhumoro Sep 18 '19 at 12:03
@ekhumoro thank you for information. I couldn't be sure if it need only `self.` or it need some method like `FileStuckture = get_by_name("FileStuckture")` which I saw in some GUI in Python - probably in `Kivy`. As for use second argument in `load_project_structure` I now saw that there is recursion and `load_project_structure` runs again `load_project_structure` with different second argument so it is still needed. – furas Sep 18 '19 at 12:29
@furas Ah - you're right, I completely missed that. – ekhumoro Sep 18 '19 at 12:32
@Robbe If this answer solved your problem, do not forget to mark this answer as correct. – S. Nick Sep 18 '19 at 12:54
