Model: ItemIsUserCheckable

[weepdoo]

Hye all

I'm still trying to create my own ItemModel for my data structure in PyQt.
This model is quiet "readable only" (and now it works great thanks to you ).
But I would like my users to be able to check a check box (that represent a boolean value).

For this column, I use the flag:
QtCore.Qt.ItemIsEnabled | QtCore.Qt.ItemIsSelectable | QtCore.Qt.ItemIsUserCheckable | QtCore.Qt.ItemIsEditable

The data are correctly display, but my user can't 'check' this check box.
I add a setData method to my model, but it do not seems to be called at all.

What am I doing wrong ?

Ok, I should be (a very bit?) stupid!

The fault was in my "delegate" where I do only something like this:

def editorEvent(self, event, proxyModel, option, proxyIndex):
        eventType = event.type()
        if eventType == QtCore.QEvent.MouseButtonDblClick:
            [...] # <- we do not care
            return True
        return False

def editorEvent(self, event, proxyModel, option, proxyIndex):
        eventType = event.type()
        if eventType == QtCore.QEvent.MouseButtonDblClick:
            [...] # <- we do not care
            return True
        return False

To copy to clipboard, switch view to plain text mode 

Should I do something "else" ?

When I replace my delegate by a simple QItemDelegate, the 'check' behavior is as I excepted, but when I had only the method:

def editorEvent(self, event, proxyModel, option, proxyIndex):
    eventType = event.type()
    if eventType == QtCore.QEvent.MouseButtonDblClick:
        [...] # <- we do not care
        return True
    return False

def editorEvent(self, event, proxyModel, option, proxyIndex):
    eventType = event.type()
    if eventType == QtCore.QEvent.MouseButtonDblClick:
        [...] # <- we do not care
        return True
    return False

To copy to clipboard, switch view to plain text mode 

The check do not work anymore...
Any idea ?

Well, filtering out mouse events is not a very good way of implementing "read-only" functionality.

• If you want the whole view to be non-editable, adjustQAbstractItemView::EditTriggers.
• If you want only certain items to be non-editable, don't return "ItemIsEditable" for them!
