Question

I have no idea how to force pyuic4 to generate QSpacerItem’s as a class members in a .py file. Everything else is generate as a members of a class, for example gridLayout

self.gridLay = QtGui.QGridLayout()

Everything except QSpacerItem

spacerItem = QtGui.QSpacerItem(20, 0, QtGui.QSizePolicy.Minimum, QtGui.QSizePolicy.Minimum)
self.gridLay.addItem(spacerItem, 0, 2, 1, 1)

Any idea how to correct that?

PS I don’t ask how to correct it manually ;).

Answer 1

There’s nothing you can do to change this behaviour through the pyuic4 interface.

However, pyuic4 is written in PyQt, so if you feel like hacking, the relevant code is in PyQt4/uic/uiparser.py. Specifically, the createSpacer and setupObject methods of the UIParser class. The setupObject method is what is normally used to create attributes for objects, but obviously the createSpacer method doesn’t currently use it.

I’m not sure why things are currently done this way. To get a definitive answer, you’d probably have to ask the project maintainer (Phil Thompson) on the PyQt Mailing List.

Also note that, if you know the spacer’s position in the grid-layout, you can access it like this:

self.gridLay.itemAtPosition(row, column).spacerItem()
