How to move QTreeWidget realtive to "main form" ?

Anonymous_Banned275

The following code is in a respose to action of button (Disolay BT devices ) in main layout.
I like to move it relative to selected point IN THE layout - for example next to the button pushed.
How ?

Secondly I do not need the "full window" display - with title, min / max etc.
Just a tree view with frame.

Please excuse me if I am not using correct Qt terms, I am still a greehorn and obviously having problems combining Qt Designer and with plain code.

Code :

// print bluetooth data to tree view
QTreeWidget *treeWidget = new QTreeWidget();
tree process here
move ?? relative to some point
treeWidget->show(); // show blank form

@AnneRanch What about https://doc.qt.io/qt-5/qwidget.html#pos-prop ?
But why do you want to position manually? Why don't you want to use layouts?
Or do you mean you want to position/move the whole window (you can do it with move() also)?

Mainly because I still do not understand the interaction , or lack of it, between Qt Designer and Qt Creator.
The example I am working on puts the whole form tree (??) at random place .
Yes, I can move it relative to desktop.
I asked for help to move it relative to main window / form.
In Qt terminology I need to have the tree CODE as "child" of "main window".
Qt Designer does not let me , I need CODE designer.
I am currently looking at QDIalog class and I think it will do what I want - in CODE.

To show your dialog at a specific point, you need to use mapToGlobal to retreive the position of the clicked button relative to the screen:

connect(button,&QPushButton::clicked, [button] (bool clicked)
       {
       QPoint xy=button->mapToGlobal(button->pos());
       xy+=QPoint(0,30);  // move down 30px
       qDebug()<<"clicked"<<xy;
       
       QDialog dial;
       dial.move(xy);
       dial.exec();

       });
