How do I create a progress bar?

[DataJuggler]

I finally created my first extension, where I load a cube and copy it to 100 rows and 100 columns. It takes quite a while, like 5 minutes or more to create 10,000. Not sure if there is any way to speed this up.

A progress bar would be nice to show, but I don’t know how to create / use it.

I tried looking through docs, but I haven’t found it yet.

Thanks

@DataJuggler There is an omni.ui.ProgressBar in the omni.ui doc. Here is the snippet:

progressbar = ui.ProgressBar(width=300)
progressbar.model.set_value(progress)   # Set float value, and maximum is 100.
progressbar.get_value_as_float()  # Get its progress.

Or you can define it’s model to customize the format string of progress.

class CustomProgressModel(ui.AbstractValueModel):

  def __init__(self):
      super().__init__()
      self._value = 0.0

  def set_value(self, value):
      """Reimplemented set"""
      try:
          value = float(value)
      except ValueError:
          value = None
      if value != self._value:
          # Tell the widget that the model is changed
          self._value = value
          self._value_changed()

  def get_value_as_float(self):
      return self._value

  def get_value_as_string(self):    # Format string
      return str(int(self._value * 100)) + "%"

Then, you can initialize progress bar like progressbar = ui.ProgressBar(CustomProgressModel(), width=300).

Thank you, I will look at this in the morning.
