Hi there,

How can I disable the add data dialog window when I drag and drop .mrml files into Slicer? Is there a command I can put into slicerrc.py to prevent the dialog pop-up window from appearing everytime and drag and drop? ![Adddatadialog](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/5/5/559c5ee6fd223198d473346e3a3d569adcfa966d.png)

Thanks

@Sam_Horvath just mentioned something about needing to do this in her own custom app - maybe she can comment, but I don’t think it was something one could override in python but I could be wrong on that.

Recently I did some overriding of the drop event in Python. See this post [Add Drag and drop import to slicelet?](https://discourse.slicer.org/t/add-drag-and-drop-import-to-slicelet/9382/4)

This is very useful, thanks a lot! I’ve used it now to make DICOM loading simpler: if you drag-and-drop files or folders while DICOM module is active then they will be always loaded as DICOM (the user does not have to choose) - see [https://github.com/Slicer/Slicer/pull/1316](https://github.com/Slicer/Slicer/pull/1316)
