Hey,

I made a little GUI using PySide2 QtWidgets and I have a QLineEdit that I want to be able to populate using information from a node.

For example, I'd like to drag a Filecache node over the input field and then have the input field populated with the output location of the filecache.

I've seen similar functionality inside Houdini itself.

I've added:

self.setAcceptDrops(True)
and
self.bgeoInput.setDragEnabled(True)

But that only works if a drag a file from windows explorer onto my input field.


Has anyone done this before?

Thanks,

Hi,

unfortunately at the moment it doesn't seem to be possible to get drag and drop events to fire in a QtWidget outside of a python panel… are you launching a dialog or such from the tool shelf?

PS… really happy if I'm wrong though

Hey,

I'm running an external script from inside Houdini yeah, but no worries - I'll work around it.

Thanks for the reply

Hey, I ended up just populating it by opening up an Explorer window to a specific location (to allow the user to select a file):

def selectInputFileSeq(self):
    textboxValue=QtWidgets.QFileDialog.getOpenFileName(self, 'Select file from bgeo sequence', currentHipFileLocation, '*.bgeo.sc')
    if textboxValue:
        try:
            bgeo = str(textboxValue[0]).split(".")[:-3][0] + ".$F4.bgeo.sc"
            self.bgeoInput.setText(bgeo)
        except:
            print "Please slecet a .bgeo.sc file!"
    else:
        print "Nothing selected!"

Not what you're after exactly, but I hope it helps.
