                                                                                                      #[account(seeds = [user_data.deposit_last.as_ref(), &[user_data.__nonce]])]
                                                                                                      

                                                                                                      There is something not correct above, then Anchor fails to read the associated account's values

                                                                                                      const userData = await program.account.userData.associated(wallet1, usdcMint);
                                                                                                      

                                                                                                      So what is the correct way to replace this soon-to-be-deprecated #[associated] above the associated account struct?

                                                                                                      You will need a function that initializes the seed with the below init and payer trait. payer should also be the same user who is actually paying the for transaction.

                                                                                                      Please note that #[instruction(bump: u8] is matching the signature of the function here, hence you will need to pass in the bump in the signature as the first argument.

                                                                                                      #[instruction(bump: u8)]

                                                                                                      So I'm try to use ScrollViewReader to programmatically scroll a horizontal scroll view. I thought it would work like scrollToItem with .centeredHorizontally in UIKit, and for the most part it does, but the last few elements in the scroll view are being forcefully scrolled to the center of the screen, despite the fact that the scroll view isn't normally able to scroll that far over (without snapping back after releasing the drag, at least). This ends up creating white space across the trailing half of the screen.

                                                                                                      I've seen some other questions about this and it seems like the general opinion is that it's not a bug? On the one hand I suppose we're telling the scroll view to center the item, and it's doing just that -- so, not a bug? On the other hand, that's not how similar functionality worked in UIKit. Also, this behavior is only happening on the trailing end of the scroll view! If it was the intended behavior I would expect that scrolling to the first element in the scroll view using .center anchor would force it into the center of the screen and leave leading white space, but this doesn't happen.

                                                                                                      Is there an elegant solution to this? Or do we have to calculate the width of our elements + spacing and figure out based on the screen width whether we should anchor .center or just scroll to the last element with anchor .trailing in order to replicate the UIKit behavior?

                                                                                                      Usage examples can be seen on the repository page, but here's a quick minimal example.

                                                                                                      ScrollView(.horizontal) { scrollProxy in

You'll need to create two deployments (say, dev and uat), and use them when referring to a step:

                                                                                                      I recently came across this website (https://sunteccity.com.sg/promotions) where the href value of a tags of each item cannot be found, but the redirection still works. I'm trying to figure out a way to grab the items and their corresponding links. My typical python selenium code looks something as such

                                                                                                      Are there any ways around getting the links of all these items?

                                                                                                      based on the answer from Thingamabobs below, the approach simply turns out to be making sure the elements you spawn are allocated to correct parents.

                                                                                                      It is worthwhile to create a frame just to hold every scrollable element since you can't move widgets around between parents when using pack/place. So a common parents between all movable elements will give you the freedom to move them around, again just create a holder frame. See the answer and discussion below for more details.

                                                                                                      EDIT2

                                                                                                      Bryan's answer below has very good info and an alternate approach using just a canvas. The core concepts still stand the same.

                                                                                                      original question begins here

                                                                                                      The situation

                                                                                                      So based on this answer by Bryan, I used this approach to spawn widgets on a scrollable frame (which is basically a Canvas wrapping a frame inside as we know cause Frames don't have scroll attributes).

                                                                                                      The widgets in this case are just tk.Buttons which I spawn in a loop using lambda to preserve state. That aspect is completely fine.

                                                                                                      The issue

                                                                                                      Now everything works fine except when I spawn more elements (again just buttons), they seem to be cut off. and I can't seem to scroll down to see the remaining ones. I am only able to scroll upwards only to see empty space.

                                                                                                      please see the video below to see what I mean (excuse my horrible color choices, this is for a quick demo)

                                                                                                      In the video, there are more elements below template47 but I can not scroll to them. I can scroll upwards but it's just lonely up there. All the names are actually buttons with zero bd and HLthickness.

                                                                                                      what I have tried

                                                                                                      To begin, my first instinct was to attach a ttk.scrollbar to the canvas+frame, which I did but observed the exact same behavior.

                                                                                                      Then I tried to see if i could use .moveTo('1.0') to scroll down to last entry and then since upward scrolling works already, shouldn't have an issue. But this didn't do anything either. Still the elements were cut off, and it obviously messed up upward scrolling too.

                                                                                                      I don't think I can use pack/grid geoManagers since as the answer by bryan i linked to above suggests, using place with its in_ arg is the preferred way. If it is possible otherwise, let me know though.

                                                                                                      my use case in a nutshell

                                                                                                      as depicted in the answer linked above, I also have two frames, and I'm using the on_click callback function to switch parents (a lot like in example code in answer). Turned out place was the best bet to achieve this. and it is, all of that aspect is working well. It's just the scroll thingy which doesn't work.

                                                                                                      some code (dare i say MCVE)

                                                                                                      The main issue is that you are using place and with place you will be the allmighty over the widget, means there will be no requested size to the master or any other magic tkinter provides in the background. So I do recommand to use another geometry manager that does that magic for you like pack. Also note that I set the anchor to nw.

                                                                                                      In addition it appears that you can only use the optional argument in_ in a common master. So the key of that concept is to have an holder frame that is used as master parameter and use the in_ for children that are able to hold widgets.

                                                                                                      I don't know if the title is worded correctly, but I will try my best to explain my problem. I now have a function that updates the current user's location, which works fine. The problem is that the painted pointer remains at that exact position because the decoration is painted once inside the widget and never changes.

                                                                                                      I have looked at how google does it with the marker object, but that didn't seem to work for my app because I am not using a normal map.

I should have probably pointed this out beforehand, but I am a complete beginner trying to learn by doing some self-coding, and any problems that I might have missed or incorrect code is highly appreciated if anyone would point it out. Thanks in advance, and happy Christmas to anyone reading.

                                                                                                      I want to retrieve the entire sentence that surrounds a link, delimited by punctuation (such as . or ! or ? or newline).

                                                                                                      The purpose is to provide a better context for the link.

                                                                                                      So for example if i have this...

                                                                                                      $input = "I don't want this piece! This is the sentence I want. In don't want this piece either";
                                                                                                      $filter = "https://example.com/my-sentence";
                                                                                                      

                                                                                                      ... I need to get to that...

                                                                                                      $output = "This is the sentence I want.";
                                                                                                      

                                                                                                      So far, I managed to isolate a sentence that doesn't contain tags, like this:

                                                                                                      $input = "I don't want this piece. This is the sentence I want. In don't want this piece either";
                                                                                                      $filter = "sentence";
                                                                                                      $regex = '/[A-Z][^\\.;]*('.$filter.')[^\\.;]*/';
                                                                                                      if (preg_match($regex, $input, $match))
                                                                                                      $output = $match[0];
                                                                                                      

                                                                                                      This works just fine. Next, I don't know how to get around the punctuation inside the url.

                                                                                                      I explored isolating the anchor first and regexing that, which works on any single example but may generate collisions in the wild (anchors duplicating other anchors or random text).

                                                                                                      Another way to go seems to be strip_tags, something like...

                                                                                                      $input = strip_tags($input);
                                                                                                      

                                                                                                      ... the problem being that I need them both stripped and not stripped at the same time.

                                                                                                      Maybe a more specific regex or some smart wrapping of the functions could bring an easy way out of this, or maybe it's a dead end and some other approach is required, I don't know, but right now I'm stuck, please help!

                                                                                                      I want to control whether a link is clickable or an error should be displayed (Based on result of an ajax call).

                                                                                                      I get to the point where I am able to set the link as "allowed to be clicked":

                                                                                                      // Authorized
                                                                                                      anchor.data("authorized", true);
                                                                                                      

                                                                                                      However when I run this code, the link still does not open. Ideally once the ajax call is complete, it should invoke the click event. I believe the issue is in this line.

                                                                                                      // Trigger Anchor

                                                                                                      This is the entire code:

                                                                                                      
                                                                                                      

                                                                                                      Notes: I am using class instead of id in the anchor because I have various links that will trigger this event. However as you can see, this should not be an issue since I am always referring to the individual object:

                                                                                                      I think we cannot overwrite the default behavior of the anchor tag but we can work around it. In this solution, I have replaced href with data-link. And mimic the anchor mechanism with window.open.

                                                                                                      Code :

                                                                                                      Please note :

                                                                                                      1. New note for security: As you can see we are using quite a visible data-link and anyone with enough effort can visit the link whether it is authorized or not. If the above answer gets you through the popup blocker, the next few things you can do is maybe only fetch accessible links from the start OR add a "show links" button and then fetch only accessible links to the user. You can do it via ajax. and also you will not need this JS/Jquery code. OR assign a random number to data-link and then fetch in your PHP code see if it is authorized if it is then only return accessible HTTP link. many ways to improve.
                                                                                                      2. You can use CSS to style the anchor tags, which I have not in the solution
