If they have to be in a single query, you simply need to use the output values of ST_X and ST_Y in the ST_MakePoint function. If the x and y values are in columns or are the result of an operation, you simply need to pass these values in the function:

You could put a pair in the result, e.g.:

Disclaimer: novice here so take this with a pinch of salt. I've provided a solution below that certainly isn't the most elegant but will help you on your way without altering too much of your code.

• We can take the section of class 'fog' out entirely for the time being to simplify things a little.
• We then take the div of class 'absolute-bg' and place this immediately below the body, making sure that all of your remaining elements are within this div and therefore (visually) 'on top' of your background.
• We then set the 'absolute-bg' class to have a lower z-index than everything else (e.g. -1).
• Next, we can take the div of 'fog-container' and give it two simple CSS properties: position: fixed; top: 0;
• This removes the element from the Document flow and places it in a fixed position relative to the browser window, in this case, top: 0.
• Finally, you want to be able to click-through your div 'fog-container' which now sits 'on-top' of everything else when rendered, therefore, we can add these two properties to .fog-container: pointer-events: none; touch-action: none;

Hope this helps. Elegant, no? A push in the right direction? Hopefully!

Updating product quantity value in Cart_products class:

You need to create a variable final ValueChanged onProdQty; in Single_cart_product class and then where the quantity value changes use the callback like this widget.onProdQty?.call(here Pass the new quantity value). Also one last step is that in class Cart_products where you are calling Single_cart_product() add this in argument onProdQty: (value) => setState(() { Products_on_the_cart[index].qty = value; }),. By doing this whenever the callback is called the setstate would run in Cart_products class and wherever Products_on_the_cart[index].qty is used it would get updated.

Updating product quantity value in CartPage class:

Note: I'm not sure if these steps would work corectly as I have limited information about your project. But you will surely learn how to pass data around using callbacks:

• Follow steps of Updating product quantity value in Cart_products class and then continue.
• Add final ValueChanged onProdQty; in Cart_products class and then change Single_cart_product() argument in class Cart_products like this:

As noted, your xpaths need the namespaces. Here's an example of how to use namespaces with lxml. Note the u: and x: prefixes in the xpath.

When you write for i in expl_sounds:, you are iterating on the elements in expl_sounds, so you can just do:

I found the solution and posted it on my initial post on the nxp forum.

The error was in the driver :

You are defining two different list'. The one inside the list comprehension list'<- (zip [0..] list) shadows the previous one. Shadowing means you have two equal names in scope but the one lexically closer is the only one visible. You want something like:

An MutableImage is one you can mutate (change in place) - Images are immutable by default. You'll need some kind of monad that allows that though (see the documentation - there are a few including ST and IO).

To get an MutableImage you can use thawImage - then you can work (get/set) pixels with readPixel and writePixel - after you can freezeImage again to get back an immutable Image

If you want to know how you can rotate images you can check the source code of rotateLeft :
