(Un)ChechkingAll from Tree View

@Karoluss96
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.

[Karoluss96]

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.

Please provide a minimal script a minimal script that creates your tree view and its content. We will then be able to reason on it properly to help you achieve your goal.

OK, so I attached it;

 def kontrolBDOTread(self): #BDOT is a name of database
        path = str(self.controlPath).replace('\\','/') + '/' + self.dlg.comboBox_4.currentText()
        
        tree = et.parse(path)#parsing XML
        root = tree.getroot()   
        wersjaSzablonuKontroli = root.get('version')
        self.dlg.label_8.setText('Wersja szablonu: '+str(wersjaSzablonuKontroli)
        model = QStandardItemModel()
        model.setHorizontalHeaderLabels(['Lista kontroli'])#Nagłówek
        self.dlg.treeView.setModel(model)
        self.dlg.treeView.setUniformRowHeights(True)
        
        i = 0
        for grupaKontroli in root:
            parent = QStandardItem(grupaKontroli.get('name')) 
            model.appendRow(parent)
            parent.setCheckable(True)
            parent.setCheckState(Qt.Checked)
            parent.setUserTristate(True)
            for kontrola in grupaKontroli:
                child = QStandardItem(kontrola.get('name'))
                child.setCheckable(True)
                child.setCheckState(Qt.Checked)
                parent.appendRow([child]) 
            self.dlg.treeView.setFirstColumnSpanned(i, self.dlg.treeView.rootIndex(), True)
            i = i + 1   
        self.dlg.treeView.show()

And how its looks like

[SGaist]

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

[Karoluss96]

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)

[SGaist]

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.

[Karoluss96]

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:

Please, a minimal script

import sys

from QtXxx.QtWidgets import QTableView
# additional imports

app = QApplication(sys.argv)

model = QStandardItemModel()
# populate your model
table_view = QTableView()
table_view.setModel(model)
# finish the ui

sys.exit(app.exec())
