问题 I want to use bokeh widgets from within a jupyter notebook to update a bokeh plot. My (somewhat hacky) code looks like this: from bokeh.plotting import figure from bokeh.io import output_notebook, push_notebook, show from bokeh.models import CustomJS, Slider output_notebook() power = 0.5 x = [1,2,3] y = [i**power for i in x] fig = figure() plt = fig.circle(x, y) def update_plot(power): x = plt.data_source.data['x'] plt.data_source.data['y'] = [i**power for i in x] push_notebook(handle=bokeh

问题 I'm creating a widget with two buttons. One of them updates the content of the widget and the second one must launch an activity. I have two PendingIntent for each action, but I can't make them both work. If one works the other one doesn't. I've revised the code and can't understand what's wrong. Any help will be very appreciated. This is the code. RemoteViews controls = new RemoteViews(context.getPackageName(), R.layout.miwidget); Intent intent = new Intent("actony.com.ACTUALIZAR_WIDGET");

问题 I got the StreamBuilder to work properly. 1 thing, every time 1 of the elements change the entire list resets. So for example each Card has a counter that I would like to see add and subtract without the screen changing. How can I do this? Here is my code (updated with full file stack) ... final FirebaseAuth _auth = FirebaseAuth.instance; final fb = FirebaseDatabase.instance.reference(); final falQuery = fb.child('NumberOnes').orderByChild('Value'); final streamQuery = fb.child('NumberOnes')

问题 I want to get the text from a button to compare it using an if-statement. Say I have this button: my_button = Button(self, text = 'hi') my_button.grid(row = 0, column = 0, sticky = W) And want to do something like this: my_text = my_button.text So that the following if-statement evaluates as True: if my_text == 'hi': # do something How can I do this in an easy way? 回答1: You can simply do: my_text = my_button['text'] Tkinter allows you to access any option of a widget this way ( height , width

问题 I'm working with a group of other programmers on an open source project built using C++ and Qt. Now, we need a naming convention for widgets (and other variables generally) to use it as a standard in all of our code so that, the code gets better readability and we get better coordination between programmers. Any advice? EDIT: Am not talking about naming new classes, instead I am talking about naming instances of Qt Widgets, let's say I have a text edit for user name, should I name it

问题 I can not figure this out, I've been struggling with it for days now, and I'm so tired of it.. I'm changing the text size of a TextView on an AppWidget with a Spinner from a Configuration Activity, and I can't get it to update correctly. It does not update the first time I tell it to, but it does update the second and third and every time afterwards. I'll really really appreciate if someone would take a look at my code Thank you very much Config class: public class WidgetConfig extends

问题 I have a Dojo widget that I'm writing that adds a label and an input box to the user's page. The for attribute of a label requires an HTML ID value, but a Dojo widget should not contain IDs in case multiple instances are created on the same page. So, does anyone have any suggestions on how to work around these conflicting needs? 回答1: Out the box, this is how the dijit registry sets WidgetID (this.id) if the configuration parameter is not present while constructing: constructor: function(args)

问题 I'm trying to create a digital clock widget with custom typeface font. I got clues from here Solution was by extending TextView and put new attribute for custom font typeface. This is a good solution compared to drawing Canvas and Bitmap solution then pass it to RemoteViews.
