[solved]QAbstractListModel - update data in table view [linux]

[s_z_p]

Yes it is a list but I didn't paste the whole code. There is only one cell in this code. What do you mean "connection doesn't make sense", which part?

[SGaist]

fileChanged gives you the path of the file that changed, not it's content, so basically you are replacing your list by a string.

Also, why are you using the model/view approach if you only have one entry ?

[s_z_p]

Model view approach is needed for let's say full version of the script.

I think I get your point about string. Let me check that.

[SGaist]

The signal will just tell you that the file has changed, it will not reload the content for you. You'll have to parse the file again and update stockdata with what you just read from it

[s_z_p]

One more thing.
file_check = QtCore.QFileSystemWatcher(['/home/user/Desktop/plik.txt'])
file_check only checks if file was changed if was:

file_check.fileChanged.connect(resetItems)
it sends signal to 'resetItems' and 'resetItems' should reload data, true?
and I have to find a way how accept the string parameter emitted by fileChanged..

[s_z_p]

Is it better ? but I have got error like that:
AttributeError: 'StockListModel' object has no attribute 'beginResetModel'

@def init(self, stockdata = [], parent = None):
QtCore.QAbstractListModel.init(self, parent)
self.stockdata = stockdata
self.file_check = QtCore.QFileSystemWatcher(['/home/user/Desktop/file.txt'])
self.file_check.fileChanged.connect(self.resetItems)

    def getItems(self):
       return stockdata

    @QtCore.pyqtSlot(str)
    def resetItems(self, path):
       self.beginResetModel()
       ....

You have to the data reloading yourself. Like in your main function.

As for beginResetModel I don't know why it's saying that

[s_z_p]

I cannot find a solution for this error.
@SGaist, writing "reloading data" do you mean file with data?

[SGaist]

Yes, that's what I mean. On you program startup you are reading that file and put it's content in the stockdata variable. When the QFileSystemWatcher triggers, you must do that parsing again.

[s_z_p]

Finally solved. 'beginResetModel', 'end...' and 'self.stockdata' in 'resetItems' are not needed. It can be done without it. Thank you for support.

You're welcome !
