PyQt collapsible GroupBox or Layout

[Christian Akesson]

Really sorry to hit this group with a question regarding PyQt, but I know there is a lot of skillz in here that does not only pertains to pyMel.

I have grown very accustomed to Maya's collapsible frame layout functionality and having the collapse action recalculating and setting the window size. 

Transitioning over to (py)Qt, I was disappointed to find that nothing seems to be collapsible in Qt land (at least not according to my Google searches).
I actually need this functionality outside of Maya as well as in Maya, so I need to find a Qt solution and not a Maya solution.

Has anyone managed to get PyQt layouts, GroupBox (preferred) or anything to collapse and give space in the UI for more functionality?
Would really appreciate any pointers.

Thanks,

/Christian

You can create a signal between the value 'toggled(bool)' of the checkbox from a QGroupBox to the 'setVisible(bool)' of a QFrame, which will function like a collpasible area.

example attached.

You could subclass QWidget and add a collapse button that handles the problem by changing the size of your widget and possibly hiding the children.

Thanks for the replies guys.

Judah, I would be interested in this approach for a more complete approach, but I am not quite sure how to go about this or where to start. Would you have any good pointers?

I ended up with an interim solution for the time being using the checkbox of the QGroupBox. I found that object.sizeHint() is really nice as it tells you what width, height the object should be. I ended up setting the height so that it would work for anything inside the groupBox.

Added code example below...a bit hacky, but it works.

/Thanks

# Signal Connection

self.connect(self.aGroupBox, SIGNAL("clicked()"), lambda gBox = "self.aGroupBox": self.collapse(gBox))

def collapse(self, gBox):

""" Collapses a QGroupBox """

# Find out if the state is on or off

gbState = eval(gBox + '.isChecked()')

if not gbState:

eval (gBox + '.setFixedHeight(15)') 

                # Set window Height

self.setFixedHeight(self.sizeHint().height())

else:

oSize = eval(gBox + '.sizeHint()')

eval(gBox + '.setFixedHeight(oSize.height())')

                # Set window Height

self.setFixedHeight(self.sizeHint().height())
