| Create Python Enum referencing a list with TkImages Posted: 07 Apr 2022 11:12 AM PDT I've got a couple of Images in a folder and each of these gets resized and turnded into a Image for Tkinter. I want to use these images in other python scripts as a enum. This is how i create the Images. ''' import os from PIL import Image, ImageTk from enum import Enum #Resize All Images and turn them into TkImages def ResizeImages(): PieceImages = [] for images in os.listdir('Resources'): cImage = Image.open('Resources/' + images) cImage = cImage.resize((80, 80), Image.ANTIALIAS) PieceImages.append(ImageTk.PhotoImage(cImage)) return PieceImages #Called from outside to create PNGS list AFTER Tkinter.Tk() was called def InitializeImages(): global PNGS PNGS = ResizeImages() #This is the part where I'm lost class Black(Enum): global PNGS Queen = PNGS[3] King = PNGS[4] Tower = PNGS[5]
''' I want to create a Tkinter Button with these images on like this: ''' #PieceImages is the .py file above import PieceImages import Black form tkinter import * root = Tk() root.geometry('800x800') someButton = tk.Button(root, image=Black.Tower).place(x=100, y=100)
''' My Question is: Is it even possible to create enums of this type and if so, how? Thanks to everyone who takes his time for this :) |

| matching two elements of two arrays in react Posted: 07 Apr 2022 11:12 AM PDT I need to match two elements of two arrays in react, it's like matching exercises. the problem is that i don't even understand the logic and i don't have any idea. I have 2 arrays, an array of questions and an array of answers which are inside div, so when i click on a question i can choose the matching answer by clicking on it. this what i've tried so far const [selectedQuestion, setSelectedQuestion] = useState(); const [selectedAnswer , setSelectedAnswer] = useState(); const [couple , setCouple] = useState(); const [matches , setMatches] = useState([]);
The idea is that after generating a couple i will add it to the matches array, but i have to test first if a couple if generated and that he has a question and an answer, second thing. In the case when user clicks question and clicks another question we have to replace the qestion choosen. please help i'm new to react and i'm struggling |

| How can I seamlessly and descretely communicate new URI launch parameters to a currently running application in Windows? Posted: 07 Apr 2022 11:11 AM PDT Case: Click a URL in the browser and a video game that is currently running on user's desktop can ingest that data and do something. I've been working on this for some time, but I don't know if I'm on the right path. What I currently have: A clickable URI in a webpage that can have different arguments for the client to recieve. The URI scheme is registered in Windows. When clicking URI in the browser it will launch a c++ console 'launcher' or 'bridge' app that is already installed on the user's PC. This 'launcher' is a middle-man that parses the URI arguments and communicates them to the main 'user' app (a video game) via IPC named pipes. How do I: In terms of UX, make the whole process descrete and seamless? Specifically, I need to: Keep launcher hidden from the user - no pop-up. Needs to be only capable of running a single instance, even when invoked with new URI parameters. Do I just exit the current and create a new one? User can click another URI in the webpage and the launcher will process the new arguments without displaying itself to the user. Tech constraints: Windows. Preferably needs to be C++. C# could be a possibily. Existing example: Zoom conferencing software appears to works similar to this. Clicking a URL in the browser launches a 'launcher' which starts the main app to video conference. Closing that 'launcher' will minimize it into the system tray. Clicking on a new link while the launcher is running does not start a new launcher, but it does start a new meeting. How does something like this normally work? |

| Fix aspect ratio of a scatter plot with an image Posted: 07 Apr 2022 11:12 AM PDT I've to plot multiple scatter and table in a grid space and I'm having a couple of issues with the relative position but most important with defining and maintaining the aspect ratio of the scatter plot. I've written a script with "fake" data on it to describe my problem and a minimum "not working" example below. What I have is a dataframe with x, and y positions of objects, and what I want to do is to put the corresponding image below. Since the image can have an arbitrary aspect ratio I need to read the aspect ratio and construct the scatter plot in that way but I'm unable to make it work. Another problem is connected with the invert_xaxis and invert_yaxis that don't work (I need that command since the scatter data are inverted. I've used the following commands, and as far as I've understood each of them should block the aspect ratio of the scatter plot to the same ratio of the figure but they do not work. The aspect ratio becomes corrected only when the figure is plotted but that eliminates the effect of axis inversion. I've had a similar problem with setting the aspect ratio of plots without the addition of a figure, sometimes it worked but not with tight_layout. It is obvious that I'm missing something important....but I'm unable to figure it out. This is the fake data code: ############################################################################### # fake data #general data aspect ratio image_height= 5 #4270 image_width = 10 # 8192 pix2scale = 0.3125 data_AR = image_height / image_width #random data generation data_width = image_width* pix2scale data_height = image_height * pix2scale data1x = np.random.uniform(-data_width/2, data_width/2, size=(40)) data1y = np.random.uniform(-data_height/2, data_height/2, size=(40)) data2x = np.random.uniform(-data_width/2, data_width/2, size=(40)) data2y = np.random.uniform(-data_height/2,data_height/2, size=(40)) temp_df1 = pd.DataFrame([data1x,data1y,['random1']*40],index = ['x','y','label']).T temp_df2 = pd.DataFrame([data2x,data2y,['random2']*40],index = ['x','y','label']).T df = pd.concat([temp_df1,temp_df2],axis = 0, ignore_index = True) del temp_df1, temp_df2 #sample image generation of variable aspect ratio img_size = (image_height, image_width) R_layer = np.ones(shape= img_size)*0.50 G_layer = np.ones(shape= img_size)*0.50 B_layer = np.ones(shape= img_size)*0.50 A_layer = np.ones(shape= img_size) img = np.dstack([R_layer,G_layer,B_layer,A_layer]) #add a mark at the top left of the image for k in range(0,3): for i in range(0,int(image_width*0.2*data_AR)): for j in range(0,int(image_width*0.2)): img[i,j,k] = 0 #add a mark at the center of the image # get center coordinates of the image center = [[2, 4], [2, 5]] for k in range(0,3): for point in center: if k == 0: img[point[0],point[1],k] = 1 else: img[point[0],point[1],k] = 0 #show image fig, ax = plt.subplots() ax.imshow(img) ###############################################################################

| Source Generator Testing Posted: 07 Apr 2022 11:11 AM PDT I'm trying to develop a source generator that I can theoretically add to my projects, and for the given project have it find classes that are marked up with a specific attribute, and then build a corresponding generated file for each. I've set up unit tests that effectively use GeneratorDriver to instantiate and run generators and evaluate their output. Problem Classes exist in a secondary project referenced from the test project. The compilation does not appear to include syntaxTree's for the other project. I've tried calling CreateCompilation with a simple program.cs body, and calling .AddReferences(MetadataReference.CreateFromFile(typeof(User).Assembly.Location), and then passing that to the in driver. At runtime, my syntax trees are still all the same (perhaps because I assume that reference is treated like an assembly reference. I assume in normal situations, generators will run with the context of projects they are referenced from as an Analyzer, but for the purposes of my unit testing, is there a way I can effectively set the compilation to be another project, or reference another project (such that when I walk the different syntax trees, I can access those classes marked with attributes in an external assembly)? |
| parse json file to Pydntic model Posted: 07 Apr 2022 11:12 AM PDT I created a model of Pydantic. But it does not convert and outputs an error Please tell me,what is wrong. classDTO:

I tried to solve the problem with Custom Root Types: Pydantic models can be defined with a custom root type by declaring the field. __root__ The root type can be any type supported by pydantic, and is specified by the type hint on the __root__ field. The root value can be passed to the model __init__ via the __root__ keyword argument, or as the first and only argument to parse_obj. |

| Pure JavaScript Datepicker displays calendar only once to never do it again in a Shopify cart page Posted: 07 Apr 2022 11:11 AM PDT To achieve greater performance with our Shopify store, we decided to minimize use of jQuery across the site. In cartpage, I added a pure JavaScript datepicker that sometimes displays the calendar just once and never afterwards. I ensured only one version of jQuery loads in the theme, thinking multiple instances from other Shopify apps might be causing this issue. But even with a single jQuery instance being loaded now in the theme, the issue still persists. I don't see any console errors. Please add a product to the cart and go to the cart page to see this issue by clicking the date picker. Below is the link to the preview theme. Following is the datepicker code for pickaday plugin. <div class="cart-attribute__field"> <p> <label for="ship_date">Ordering early? Pick a future ship date here:</label> <input id="ship_date" type="text" name="attributes[ship_date]" value="{{ cart.attributes.ship_date }}" /> </p> </div> <p class="shipping-text">If you are placing an order with <b>a future ship date</b> that <u>also</u> includes multiple addresses please email <a href="mailto:support@packedwithpurpose.gifts" target="_blank">support@packedwithpurpose.gifts</a> upon placing your order to confirm your preferred ship date.</p> <!-- Added 11162020 --> <p class="shipping-text">Please note that specifying a date above ensures your gift is packaged and shipped on that date. <b>This is not a delivery date.</b> As we work with third party shipping agencies, your delivery date is subject to the specific carrier selected as well as your shipping destination.

| Mongoose with TypesScript slows down VSCode code completion Posted: 07 Apr 2022 11:11 AM PDT I have seen that Mongoose supports TS. I have followed their official getting started guide: https://mongoosejs.com/docs/typescript.html And since then, my code completion are very slow - unless I remove this package. |
| Ordinal numbers replacement Posted: 07 Apr 2022 11:12 AM PDT I am currently looking for the way to replace words like first, second, third,...with appropriate ordinal number representation (1st, 2nd, 3rd). I have been googling for the last week and I didn't find any useful standard tool or any function from NLTK. So is there any or should I write some regular expressions manually? Thanks for any advice |
