PyQt absolute position of QWidget

Question

I have a QDialog which has a layout, in this layout there are multiple QWidgets. Now I have a button, if the user presses this button I want to display a "tooltip" which displays some more information. This "tooltip" has to contain a layout.

For this I wanted to use a QWidget with an absolute position. When I put together the code mentioned in this question the solution does not work for me. I have also tried to use the QtWidget.raise_() function but the QWidget is not being displayed.

I stripped down my code to the following example:

# creating content layout = QtWidgets.QVBoxLayout() for i in range(0, 10): layout.addWidget(QtWidgets.QLabel("line {} - bla bla bla bla bla bla".format(i))) widget = QtWidgets.QWidget() widget.setLayout(layout) # creating dialog and apply the layout dialog = QtWidgets.QDialog() dialog.setLayout(layout) # creating the absolute positioned widget absolute_layout = QtWidgets.QVBoxLayout() absolute_layout.addWidget(QtWidgets.QLabel("Absolute positioned QWidget")) absolute_layout.addWidget(QtWidgets.QLabel("With some widgets in itself")) absolute_layout.addWidget(QtWidgets.QLabel("With some widgets in itself")) absolute_layout.addWidget(QtWidgets.QLabel("With some widgets in itself")) absolute = QtWidgets.QWidget(dialog) absolute.setLayout(absolute_layout) # show the absolute widget and move it absolute.show() absolute.move(10, 10) absolute.raise_() dialog.show()

The dialog is shown correctly with the content in the layout but the absolute is not being shown.

What am I doing wrong?

There is really no point in using widgets for such a trivial task as this. A tooltip can render html, so just use a <table> for laying out the text. — ekhumoro

@ekhumoro yes, I know that. The code written above is obviously not my real code. As I wrote I need to use a QLayout object in this "tooltip", this layout contains some custom widgets. With using html I cannot achieve the result I want to have. — miile7

By using...

absolute = QtWidgets.QWidget(dialog)

you have made absolute a child of dialog. Hence the geometry of absolute will always be governed to some extent by dialog. If you want to be able to specify the absolute geometry of a widget use...

absolute = QtWidgets.QWidget()

But don't I have to make the absolute a child of dialog? If I call the show() method of a QWidget which does not have a child it will be shown as a new window.

So with the help of @G.M. I found out that the solution is really easy:

absolute = QtWidgets.QWidget() absolute.setParent(dialog)

I was expecting that the QWidget::QWidget(QWidget * parent = 0, Qt::WindowFlags f = 0) constructor is calling the QWidget::setParent(QWidget * parent) method internally (which is not true?).
