DatasetDialog

This module provides a dialog widget to select a HDF5 dataset in a tree.

class DatasetDialog(parent=None)[source]

This QDialog uses a silx.gui.hdf5.Hdf5TreeView to provide a HDF5 dataset selection dialog.

The information identifying the selected node is provided as a silx.io.url.DataUrl.

Example:

dialog = DatasetDialog()
dialog.addFile(filepath1)
dialog.addFile(filepath2)

if dialog.exec():
    print("File path: %s" % dialog.getSelectedDataUrl().file_path())
    print("HDF5 dataset path : %s " % dialog.getSelectedDataUrl().data_path())
else:
    print("Operation cancelled :(")
