Widgets exist for displaying integers and floats, both bounded and unbounded. The integer widgets share a similar naming scheme to their floating point counterparts. By replacing Float with Int in the widget name, you can find the Integer equivalent. The FloatLogSlider has a log scale, which makes it easy to have a slider that covers a wide range of positive magnitudes.
The min and max refer to the minimum and maximum exponents of the base , and the value refers to the actual value of the slider. The numerical text boxes that impose some limit on the data range, integer-only impose that restriction when the user presses enter. There are several widgets that can be used to display single selection lists, and two that can be used to select multiple values. All inherit from the same base class.
You can specify the enumeration of selectable options by passing a list options are either label, value pairs, or simply values for which the labels are derived by calling str. Selection widgets no longer accept a dictionary of options. Pass a list of key-value pairs instead. The following is also valid, displaying the words 'One', 'Two', 'Three' as the dropdown choices but returning the values 1, 2, 3. The value, index, and label keys are 2-tuples of the min and max values selected.
The options must be nonempty. There are several widgets that can be used to display a string value. The Text , Textarea , and Combobox widgets accept input. The Label widget can be used to construct a custom control label. The Password widget hides user input on the screen.

A file like object with a read method. BytesIO pd. I've been looking into this, and it seems there are two reliable solutions. Important to remember that this will place the data in the HTML page and therefore the user's browser, so trying to put a lot of data there could lock up their system.

You signed in with another tab or window. But I am not sure how much this can help me in general. In my case, the file doesn't exist when init the button, instead, it's computed after clicking the button. I am actually looking for a way to let the button trigger both of the computation and downloading.
Button : """Download button with dynamic content The content is generated using a callback when the button is clicked.
This is great - I've started to use this in my implementation s now. Thank you! Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password. Post as a guest Name. Email Required, but never shown.
