            For the past few days I have been attemping to set up JavaFX on my M1 Mac. I was able to get it working using Java 18, but unfortunately I need to be using Java 11 for school.

            I don't have an M1 Mac to test, but did you try the build of JDK 11 with JavaFX included that Azul provides? I saw that you mentioned zulu-11, just not sure if you picked the version with JavaFX bundled.

            Be sure to choose “macOS”, “ARM 64-bit”, and “JDK FX” in the various pop-up menus of the download page.

            Issue firing a valid cancel CellEditEvent when editing from one cell to another
            Asked 2022-Mar-24 at 22:42

            I am implementing an editable TableView which relies on the CellEditEvents for cancel, start & commit events.

            In the below example, the city column is editable, and the corresponding events are triggered when:

            • Cancel: Pressing escape in text field or when the focus is lost from text field.
            • Commit: Pressing enter in text field.

            The start and cancel events are triggering properly when I traverse from an editing cell to the RadioButton. But it is throwing error when traversing from one cell to another.

            Please check the below gif(for steps) and the console output.

            Ok.. as I have to look for a workaround till I upgrade to JavaFX 17, below are the changes I came up with (for JavaFX 8):

            Firstly, adding a null check for TablePosition in the onCancelEdit event handler to ensure no errors are thrown because of the internal bug.

            Unable to delete .mp3 file due to javaFx MediaPlayer
            Asked 2022-Mar-20 at 00:05

            I am working on my Hhighschool capstone. It is a program where the user can download songs from the internet and store them in an organized manner and play them. My program must contain a feature where the user may delete a specified .mp3 file by simply pressing a button. I have tried the .dispose() method on the MediaPlayer, and then trying to delete the file which doesn't seem to be working. It creates an error saying that the .mp3 file is still being used. How would I stop Javafx from accessing the file? I have searched online for answers but none of them have answers which fit my needs. If anyone could provide me with some code to fix my problem that would be greatly appreciated! Here's a Mini Reproducible Example below!

            Thank you to @Slaw for providing a solution to my problem. To solve my issue, I created a deletionQueue ArrayList which would hold the paths to the files I would like to delete. Once .dispose() is used on the MediaPlayer, after a certain amount of time has passed, those files would be automatically deleted.

            What is an audio block?
            Asked 2022-Feb-27 at 18:33

            I've seen some sentences including a word 'block'.

            Pd lightens its workload by working with samples in blocks rather than individually. This greatly improves performance. The standard block size is 64 samples, but this setting can be changed. (http://pd-tutorial.com/english/ch03.html)

            Rendering an audio graph is done in blocks of 128 samples-frames. A block of 128 samples-frames is called a render quantum, and the render quantum size is 128. (https://www.w3.org/TR/webaudio/#rendering-loop)

            So, what I wonder are:

            (1) What is wrong with handling samples individually? Why audio samples are grouped by a block of a some size (64, 128) ?

            (2) Why the block size is a power of 2? // 2^6 = 64, 2^7 = 128

            (3) After grouped, to where the samples go? Are they then played by a sound card or something?



            Answered 2022-Feb-27 at 03:22

            A audio block is an array of floating point numbers representing audio. Where the numbers range from [1, -1] and where 0 (not 0.xxxx) is no sound.

            1. What is wrong with handling samples individually? Why audio samples are grouped by a block of a some size (64, 128) ?

            From my understanding handling samples in frames is better because of how web audio api runs in the browser due to performance. Different frame sizes can vary on the users performance on their PC. This is similar to fps on a video. In web audio there is node called ScriptProcesssorNode which allows you to create custom audio processing in a event handler at specific buffer/frame size. However the buffer size only ranged from 256 - 16384 or undefined for system preferred. It's simple on each function call it contains a new frame of audio. Basically it's a loop.

            Now these days the ScriptProcessorNode is now deprecated/obsolete because of bad performance. This is because of the event handler onaudioprocess function is on the main thread which can block a lot of things. This is replaced with a AudioWorklet which is similar to the ScriptProcessorNode but each process call is only 128 frames and save better performance on the main thread because the AudioWorklet runs on the worker thread in background.

            2. Why the block size is a power of 2? // 2^6 = 64, 2^7 = 128

            I honestly don't exactly know but my best guess is that it is easier to calculate since in 8 bit alike numbers such as 8, 16, 32, 64, 128, 256 etc.

            3. After grouped, to where the samples go? Are they then played by a sound card or something?

            Web audio api is node graph system where sample frames (a.k.a 128 frame block) is passed through different nodes such as effects like BiquadFilterNode or custom processing blocks like AudioWorkletNode, etc. There is a node called AudioDestinationNode which is the speaker hardware output of the users PC. Any connection is connected to this particular node, (if there is sound), It will produce sound from that connection. Think of these nodes as a connect the dots with point A is the start and point B is the end. Each dot is a processing block like the AudioWorklet, etc, where point A is the source like a mic or a mp3/wav file and point B is the speaker destination. Connect them together, boom! You got amazing sounds.

            I hope this makes sense and what your looking for :)
            Feel free to correct me if have it wrong.

            Answered 2021-Dec-15 at 20:11

            The way to avoid this problem is to write the .hometext1 class style as you see fit in the blocks below. The test application is available at this link. You are having problems because the @media block you added continues to be applied when the page is minimized. Delete the @media block you added and apply the styles you expect when the page gets smaller, using the following structure.

            You can just mutate the data set using your xml_scraper function. You need do the mutate "rowwise", since your function isn't vectorized.
