QUESTION
I have a simple component see below, that basically attempts to grab some data from the formik FormContext using the useFormikContext hook.
However when attempting to write unit tests for this component it wants me to mock the hook which is fine, however, mocking the hook with typescript means returning well over 20 properties most of which are a variety of methods and functions.
Has anyone found a better way of doing this? Just seems a bit annoying even if I get it to work as I only need 1 field from the hook.

Answered 2021-Dec-22 at 13:29I resolved this issue not 100% sure it is the best solution but have posted here in case it helps anyone with a similar issue.
I basically overwrote the FormikType allowing me to ignore all of the fields and methods I wasn't using, it clearly has some drawbacks as it is removing the type-safety, but I figured since it was only inside the unit test it is somewhat okay.

I have created a GUI app in Python tkinter for analyzing data in my laboratory. There are a number of buttons, figures, and canvas widgets. It would be helpful to take a screenshot of the entire window ('root') using just a single button that saves the filename appropriately. Example using Mac's built-in "screenshot" app here.
Related questions here, here, and here, but none worked successfully. The final link was almost successful, however the image that is saved is my computer's desktop background. My computer is a Mac, MacOS Monterey 12.0.1.

...ANSWER
Answered 2022-Jan-14 at 22:44First, I didn't have an issue with the grab showing my desktop, but it was showing an improperly cropped image.
I have found a hacky solution. The issues appears to be with the resolution. So the dimensions need some scaling.
What I did was get the output from ImageGrab.grab().save(full_file_name) ( no cropping ) and measure the size of the desired image area in pixels. These dimensions will be called x_pixels and y_pixels.
Then I measured that same area on the actual window in screen units. I did this by bringing up the mac screenshot tool which shows the dimensions of an area. I then call these dimensions x_screen and y_screen. Then I modified your screenshot function as follows.
QUESTION
I am very new to using Flutter and have never properly used an API without help. I want to make my application free (without tons of ads) so I was hoping to create a Patreon to support it's upkeep. When looking for tutorial videos online or any examples of code to use for either Flutter or any other languages I know how to use, I came up empty handed. So I was posting this question here hoping that someone could help me link the Patreon API to Flutter. The documentation doesn't say it connects directly to Flutter, so you'll have to use another language to access the information (best bet is Javascript or Python on my opinion) and relay that too Flutter.
I (and possibly other people) would need a button created for OAuth login through Patreon (that works on both iOS and Android). When the user goes through the login, it needs to grab which tier they are supporting, their username, and when their subscription will renew (monthly or yearly?). This then needs to be translated to Text widgets (displaying the tier and/or username) and a "visible:" property for Visibility widgets (displaying certain content based on the user's monthly subscription and making the same content invisible or put behind a newly visible lock page when their subscription ends/expires).
Sorry I know this is a lot to anwser, but I'm not very experienced with APIs and Flutter. I will appreciate any anwser that helps because I really want to make my app without tons of advertisements and I'm hoping this question will help other Flutter developers with the same goal of supporting their development financial without tons of advertising effecting the user's experiences on the app.
Patreon API OAuth Documentation https://docs.patreon.com/#oauth
Flutter JS (I think this may help connect with the Patreon API, but I'm not sure?) https://pub.dev/packages/flutter_js
Examples of code and a step by step guide would be fantastic, but anything will help. Thank you again!

QUESTION
I am using Panzoom JS to zoom in on a map. It is working just the way I need it for zooming in and out on mobile and desktop. When you click on an item on the map, I grab the x/y coordinates relative to the top left of the container taking into account any scale applied, then look up that location/page in the database and open it. This all works great on desktop, but not on touch. I need to be able to catch the touch up location (just as if you'd clicked with a mouse) but only if there was no touch move, so I can distinguish between a pan/move, a pinch/zoom and a tap/touch-up (click). I can't find any documentation to work this out. Any help would be appreciated.

QUESTION
Hello Stack Overflow!
This is my first time posting on the site so please bare with me and my question. My class was tasked with individually creating a password generator using JavaScript. Thankfully I had gotten most of the application operating correctly, but I've gotten stuck on a problem.
Example: The user chooses to have 8 characters in their password and chooses to include special, lowercase, and uppercase characters. When the password is generated sometimes it won't include all of the character selections. (Sometimes it'll generate a password with both special and uppercase characters, but not have a single lowercase character).
I've been finished with this assignment for a minute now, but my goal is to understand what I can do to fix this problem and complete this app anyway. I was thinking of potentially removing the passwordOptions object and turning each option into an array of their own, what are your thoughts?
Thank you so much for any suggestions! :D
...ANSWER
Answered 2022-Jan-14 at 12:19The best way I can imagine is to pick one character from each selected category, then select the remaining characters randomly, finally, shuffle the selected characters.

QUESTION
Thanks for taking the time to review my post. I hope that this post will not only yield results for myself but perhaps helps others too!
IntroductionCurrently I am working on a project involving pointclouds generated with photogrammetry. It consists of photos combined with laser scans. The software used in making the pointcloud is Reality Capture. Besides the pointcloud export one can export "Internal/External camera parameters" providing the ability of retrieving photos that are used to make up a certain 3D point in the pointcloud. Reality Capture isn't that well documented online and I have also posted in their forum regarding camera variables, perhaps it can be of use in solving the issue at hand?
Only a few variables listed in the camera parameters file are relevant (for now) in referencing camera positioning such as filename, x,y,alt for location, heading, pitch and roll as its rotation.
Currently the generated pointcloud is loaded into the browser compatible THREE.JS viewer after which the camera parameters .csv file is loaded and for each known photo a 'PerspectiveCamera' is spawned with a green cube. An example is shown below:
The challengeAs a matter of fact you might already know what the issue might be based on the previous image (or the title of this post of course ;P) Just in case you might not have spotted it, the direction of the cameras is all wrong. Let me visualize it for you with shabby self-drawn vectors that rudimentary show in what direction it should be facing (Marked in red) and how it is currently vectored (green).
Row 37, DJI_0176.jpg is the most right camera with a red reference line row 38 is 177 etc. The last picture (Row 48 is DJI_189.jpg) and corresponds with the most left image of the clustured images (as I didn't draw the other two camera references within the image above I did not include the others).
When you copy the data below into an Excel sheet it should display correctly ^^
...ANSWER
Answered 2022-Jan-02 at 22:26At first glance, I see three possibilities:
It's hard to see where the issue is without showing how you're using the
createCamera()method. You could be swappingpitchwithheadingor something like that. In Three.js, heading is rotation around the Y-axis, pitch around X-axis, and roll around Z-axis.Secondly, do you know in what order the
heading, pitch, rollmeasurements were taken by your sensor? That will affect the way in which you initiate yourTHREE.Euler(xRad, yRad, zRad, 'XYZ'), since the order in which to apply rotations could also be'YZX', 'ZXY', 'XZY', 'YXZ' or 'ZYX'.Finally, you have to think "What does
heading: 0mean to the sensor?" It could mean different things between real-world and Three.js coordinate system. A camera with no rotation in Three.js is looking straight down towards-Zaxis, but your sensor might have it pointing towards+Z, or+X, etc.
I added a demo below, I think this is what you needed from the screenshots. Notice I multiplied pitch * -1 so the cameras "Look down", and added +180 to the heading so they're pointing in the right... heading.
