Here we create two widgets and display them both. Mylink = widgets.jslink((text, 'value'), (slider, 'value')) This is known as "synchronization of attributes". What this means is that when one widget is updated, the other will be too. For example, you can link a FloatText widget to a FloatSlider widget. Some Jupyter widgets can be linked together. When you run this code, you will see that the widget looks a bit different: For example, if we wanted to, we could set a few of our Slider's properties when we create it:ītn = widgets.IntSlider(value=10, description='My Slider', Widgets also support setting properties when you instantiate the widget.

If you run this code, you will see the slider update its value and description. So if you wanted to set the slider to a new value and add a description, you could do the following:

For the full list of a widget's keys, you can consult the documentation for the widget, read the source or just run this:Īlso worth mentioning is that you can also set a property to a new value. Widgets also have keys, which are such things as `description`, `min`, and `max` and `disabled`. When you run this, it will print out the current value of the slider. Then create a new cell and enter the following code: Try adjusting the slider to something above zero. If you ran this new cell, you would get output like this:

Let's say you put the code above in a new cell just below the cell that contains the code for your `IntSlider` widget. If you want to get a full listing of widgets properties and methods, you can use Python's dir()įunction to introspect the widget for you: Jupyter widgets follow a set of rules for their properties. If you want to remove the widget, just clear the cell. You can close a widget by calling its close() method. Of course, if you had created two IntSliders and assigned them to unique variable names, then you could move them independently of each other.
You can think of these two sliders are two views to the same object. The actual visible widgets are both pointing to the same object underneath, so when you move one you are effectively moving the other. The reason that this happens is that we only create ONE slider object. You will quickly discover that when you move one slider, the other slider also moves. If you put the code above into a cell in your Notebook and run it, you should see two sliders: Now let's back up a second and create that slider again, but this time around we will use display to show it twice: Finally we called the display function and passed it the widget object. Note that we had to specify its description so that the button would have a label. Here we add the extra import that we need to display a widget and we create a simple Button. If you want to save the widget to a variable, then you will need to tell Jupyter to show the widget using the display function:ītn = widgets.Button(description='Press Me') When you run the cell, you should see something like this:Īs you can see, the default value is zero for the slider. Create a new Jupyter Notebook and put the following code into a cell: Let's create a simple slider for demonstration purposes. Creating a WidgetĪ widget can be created really easily. In this tutorial we will create the widgets directly and learn more about how they work.

We looked briefly at how to create widgets using the interact and interactive functions in the previous article. The widgets synchronize stateful and stateless information between Python and Javascript. If you haven't, then let's just take a second to define what they are for.Ī widget is used to create an interactive graphical user interface for your user. If you have ever created a user interface in the past, then you probably already understand what a widget is.
Or you can run the following code in your Notebook: For a full list you can check out the documentation. We won't cover every type of widget in this article, but we will get to see a fairly wide range of them in action. Jupyter supports a fairly wide array of widgets including the following:
What are Jupyter widgets? A widget is an "eventful python object" that in the case of Jupyter Notebook, resides in the browser and is a user interface element, such as a slider or textbox.
