示例1: __init__

# 需要导入模块: from qtpy.QtWidgets import QTableView [as 别名]
# 或者: from qtpy.QtWidgets.QTableView import setSortingEnabled [as 别名]
    def __init__(self, plotted_lines, *args, **kwargs):

            table_view = QTableView()

            # disabling sorting will significantly speed up theWidget
            # plot. This is because the table view must be re-built
            # every time a new set of markers is drawn on the plot
            # surface. Alternate approaches are worth examining. It
            # remains to be seen what would be the approach users
            # will favor.

    # in wavelength, and consequently difficult to read and use, so
    # having a sorting option is useful indeed. It remains to be seen
    # what would be the approach users will favor. We might add a toggle
    # that users can set/reset depending on their preferences.

    # to sort by wavelength on load. Doesn't seem to affect performance
    # by much tough.
