I have a LazyVGrid and a NavigationBarItem button that changes the number of columns. It cycles through 1, 2, 3 then back to 1, etc. I use the .animation(.default) modifier to animate this change. When there is just one column I use a different cell structure that includes a small Map element. I have a contextMenu that works fine for 2 and 3 columns but crashes instantly when used on the single-column cell.

AnimationError[2652:855376] [Unknown process name] CGImageCreate: invalid image alphaInfo: kCGImageAlphaNone. It should be kCGImageAlphaNoneSkipLast

This crash occurs only on my iPhone 11 Pro real device, the simulators handle it fine. If I remove the animation, all is good.

A compilable, stripped-down version:

Below is an example of the data I want to manipulate in my select statement.

I have an error in my MySQL program, even though my friend doesn't get the error after he autogenerated it

I have a randomly generated array of colored tiles that I add to a gridpane for a game. As of yet, there is really no functionality, other than the tiles being toggle buttons. Here's a snippet.

I apologize for the obnoxious blue background. I added it just to further clarify my issue.

What you see is my tile images being applied to buttons. What I want is the button borders to (preferably) be nonexistent, or disappear somehow.

I just want to see my tile images as the buttons themselves.

I have tried fiddling with borders, clips, opacity, etc... I cannot get anything definitive.

Assuming all necessary imports are there and that the randomlyPopulate method in TileArray is called in another class...

Tile.java

The title may be a bit vague, so allow me to define it a little better. I have a working piece of code (down below): a simple main menu for a game I am working on. Everything works well, except for the Start button.

What I want to be able to do is click the Start button, and have a new scene appear on the same stage (window). I do not want to see a new window open. I have talked with someone more experienced in Java, and they told me to create separate classes for the MenuFX and the GameFX. If that is the case, I would need to call some start or launch method on the GameFX class from the MenuFX class, correct? Is this the best approach, or would I want to keep all FX-related code in one class? Also, I should keep the same stage for all FX work, no?

This post shed some light on things, but I am not well-versed in some of the terms discussed- for instance, I still do not understand the concept of Root.

Also, this post talks about a similar application, but I am not using FXML or SceneBuilder... I do not know if any of it is relatable.

MenuFX.java - I have removed some of the working code, simply for brevity. You can see that all I need help with is tying the Start button to some functionality that makes a new empty scene.

Below is the code sample, with other features left out. The code below encompasses the media player only. It's used on a menu screen for a project I'm working on. My issue is getting the musicButton (which is a toggle button- On/Off) to work properly. Using the following code, when I interact with the music toggle button, the playing music stops. When I click it again to resume playing, it does not resume. It stops once and stops altogether.

You can see I've tried simply using the boolean values of the toggle button in two if statements... If it's off and pressed, pause the music. If its on and pressed, resume the music. The problem is, as stated earlier, pausing the music works but it cannot be resumed. I've tried some combinations with loops, but nothing worked either.

I think if statements are too simple for this. I've scoured the JavaDocs and various online articles but I cannot find anything definitive. I've read a little about listeners, but they seem overly-complex for an on/off switch.

My question: How do I get the musicButton to pause/play the music, whenver the user clicks it?

Any help is appreciated, thanks.

i am making a filter for my page. Everything works but the only problem i cant get solved is how to give a style to the button i press on. When i try it with jQuery it gives all the buttons the style.

Here is the code I am using:
