    Why, and what do you expect this to achieve? @SGaist said you should call setCheckState() on each QStandardItem, what about that?

      You don't put checkboxes in the model.

      In your original code snippet you are correctly making the item checkable. This will trigger the view to show checkboxes. When you want to change them all, go through all the items in your model and call setCheckState on them.

      Now i have in function checkall that:

      checkBoxList= QStandardItem() 
       checkBoxList.setCheckState(Qt.Checked)
      

      no error, but when I unchecked some boxes in TreeView they don't chacked after cliking this button

        @Karoluss96
        Why would you name a single QStandardItem() as checkBoxList? Won't that just confuse you and me?

        You seem to be creating a QStandardItem into a local variable. I really don't know what you are doing with that item, if anything. You are supposed to be calling setCheckState() on each item in your model, which is what the view is displaying.

        While I notice it, you showed originally:

                for checks in checkBoxList:
                    if  checkBoxList.CheckState():
                        checkBoxList.setCheckState(Qt.Checked)
                        print(checkBoxList)
        

        What is the point of a for checks in checkBoxList loop if you only access checkBoxList inside it?

          I need an access for data in tree View, which is make in a different function.
          I'll show on attached photo: Przechwytywanie.PNG
          is in polish so: "zaznacz wszystko"="check all"
          odznacz wszystko ="un check all".
          Right, I thought that loop will be better, but all times
          but I have an error: " 'QStandardItem' object is not iterable"

            Exactly, it is not. If a single QStandardItem, or a single checkbox, is named checkBoxList it's not helpful. There is no list and nothing to loop over.

            I don't know what to say that @SGaist has not stated clearly in:

            My suggestion is that you use that QStandardItemModel directly and go through all the items you want/need to modify their value.

            calling setCheckState(Qt.Checked) on each item.

              yes, the variable name 'checkBoxList' is confusing, but it doesn't matter for that I need a loop for all Checkboxes as I shown in the print screen above

                Then change it, and get rid of " " 'QStandardItem' object is not iterable"" error.

                I need a loop for all Checkboxes as I shown in the print screen above

                And I referred you to @SGaist's answer to that, which is what you need to do.

                    When you want to change them all, go through all the items in your model and call setCheckState on them.

                    1. Do you know how to go through all the items/rows in your model? Suppose you wanted to print out (or change) the text of each item, like Kontrola atrybutowe, Kontrola 1, Kontrola 2, etc. How would you do that?

                    2. Once you have the loop for 1, presumably you know how to call setCheckState(Qt.Checked) on each item visited.

                      1. If put print (QStandardItemModel()) I gain: <PyQt5.QtGui.QStandardItemModel object at 0x00000229EA8F7160>
                        all data in Tree View come from parsed xml (to variable tree) file (I can't publish them), by

                      and later

                        No. I'm afraid you do not seem to have a grasp of models/what is going on. You might benefit from reading up on this in the documentation.

                        The answer to, for example, how do I set every checkbox in my model would be:

                        for i in range(model.rowCount()):
                            model.item(i).setCheckState(Qt.Checked)
                        

                        If you want to only check items in and below some one particular node you would need to recurse down its descendants. But you asked for check every item.

                          Looks useful, pretty and short, but I still didn't see its results- It need to take data from treeView!

                            A QTreeView does not store any data. It's a view onto a model. The model is where you store the data. @SGaist has said this, I have said this. I suggested you might like to read up on Qt model/view architecture.

                                    By minimal script, I meant a script that we can run ourselves on our machines which is not possible with what you posted.

                                      Well, it's a UI plugin. It need to be a part of QGIS program (it's free on download by: https://qgis.org/pl/site/forusers/download.html)

                                        The fact that you need to write a plugin for QGIS is currently unrelated to your issue hence why I am requesting a minimal script that creates a QTreeView with the model and the buttons you want. With that we can fix the current issue you have and you can then update your plugin code with that.

                                          aaaa Ok,
                                          The whole code is too long, as this tab is one of 5 which make this plugin, so I put only that what is here important:

                                           def __init__(self, iface):
                                                  """Constructor.
                                          
                                                  :param iface: An interface instance that will be passed to this class
                                                      which provides the hook by which you can manipulate the QGIS
                                                      application at run time.
                                                  :type iface: QgsInterface
                                                  """
                                                  # Save reference to the QGIS interface
                                                  self.iface = iface
                                                  # initialize plugin directory
