PyQt change Widget Parent

Question

I'm having trouble changing the parent of the widgets added directly to a frame on PyQt5

I have a grid of frames positioned in another frame without layout, this is because I need a free positioning mechanism instead of the girdLayout.

This is my process:

1. on a For Loop I Create multiple ClusterFrames and setParent(gridFrameContainer)
2. Create the widgets, buttons and labels for each ClusterFrame

Everything works ok, all the ClusterFrames are displayed, resized and repositioned when I use ClusterFrame[i].setGeometry

The problem is when I need to remove a ClusterFrame[i] from the frame, as you might know, it's very hard to delete a widget if I don't have a layout.

I've tried ClusterFrame[i].close(), ClusterFrame[i].deletelater del(ClusterFrame[i])...

Since nothing has worked for me, what I do is:

1. Create a topFrame
2. Create a stacked Layout for topFrame
3. Create gridFrameContainer
4. Add gridFrameContainer to stacked Layout
5. on a For Loop I Create multiple ClusterFrames and setParent(gridFrameContainer)
6. Create the widgets, buttons and labels for each ClusterFrame

Here works ok, no problems here.

When I want to change the quantity of ClusterFrames

1. On a For Loop I change the parent of each ClusterFrames as ClusterFrames[i].setParent(None or MainWindow)
2. On the StackedLayout I delete the current gridFrameContainer
3. On the StackedLayout I add a NewGridFrameContainer
4. On a For Loop I change the parent of each ClusterFrames as ClusterFrames[i].setParent(NewGridFrameContainer)

But they're not displayed anymore.

It seems like I can only set the Parent once, is that right? if so, the I need to delete each ClusterFrame and create it again?

When I create the widgets of ClusterFrames, I set the parent only of the frame, but never of each widget of the cluster like buttons, labels, I suppose that they belongs to the ClusterFrame parent right?

If I change the parent of the frame ClusterFrame, should I change the parent of his widgets?

Thanks

Here's an example: (Press the button to change the parent)
