setRowStretch() dynamically change?

[Schiho]

After Creating a Grid-Layout i would like to change the setRowStretch() dynamically, when adding new Elements. How is that possible. It seems that the setRowStretch() is frozen, when i once set it and start the application.

Hi,

Can you share a sample code where you setup your QGridLayout and call setRowStretch ?

[Schiho]

spacerItem = QSpacerItem(20,80,QSizePolicy.Minimum,QSizePolicy.Expanding)

n = self.grid.rowCount() + 1
self.grid.addItem(spacerItem, n, 1)
self.grid.setRowStretch(n, n)

Theoretically, everytime i call t his function, the last element will be stretched the most right?

It won't make the row itself bigger, it will allow it to grow more if needed.
