            Hide subcategories from woocommerce category BLOCK widget on WP 5.8
            Asked 2022-Apr-02 at 09:04

            With the update to WP 5.8 and WC 5.6 the "woocommerce_product_categories_widget_args" filter no longer works, which hook should I use to be able to customize the new product categories block widget?

            The solution mentioned in this post Hide subcategories from woocommerce category widget it worked before upgrading to WP 5.8, and it still works if I install the Classic Widget plugin, but I want to use the new block widgets available from WP 5.8 version without using Classic Widget plugin:

            ANSWER

            Answered 2022-Apr-02 at 09:04

            You have to use the Classic Widget plugin, or you need to write your own code. The current widget block, that displays the categories, does not have any filter hook points included, that allow you to modify it.

            Your last resort option may be to extend the class ProductCategories in the Blocks src folder, which is now responsible for rendering the list.

            Audio widget within Jupyter notebook is **not** playing. How can I get the widget to play the audio?

            Regarding the Free Spoken Digit Dataset, I managed to track the error with your usage of activeloop hub and audio display.

            adding [:,0] to 9th line will help fixing display on Colab as Audio expects one-dimensional data

            iOS widget background-image goes black after couple of minutes
            Asked 2022-Feb-02 at 07:54

            I am currently developing an iOS widget with SwiftUI and have a strange behaviour of the background-image of my medium-sized widget.

            I am setting a background-image depending on the current color mode of the device, which works most of the time. But when the app is in the background for a couple of minutes, the background-image goes black, which makes the text unreadable. Any other UI-elements are still visible. When I resume to my app, the widget refreshes itself and the background-image is visible again.

            The background-images are included in my image.assets of my widget-extension, so it should be always accessible for the widget, shouldn’t it?

            This widget is available for iOS 14 and above.

            This is how I set the background-image:

            Since the problem only occurs with these two specific images it seems like the files are either

            1. Not correctly added to the assets folder
            2. Broken or corrupt

            Try to generate a completely new file for both pictures (e.g. take screenshots) and replace them with the current images in the assets folder. That should most likely fix your issue.

            Kivy widget generation very slow
            Asked 2022-Jan-25 at 08:32

            I'm making a kivy app to find the rhyming words for a word entered by the user. It displays all the rhyming words as OneLineListItems in an MDList which is inside a kivy RecycleView. On clicking on one of these OneLineListItems it displays the definition of the word on the right-hand side of the screen. However, when I click on a OneLineListItem its definition takes very long to appear and sometimes it lags so badly that the app closes. Am I doing something wrong or is it just my computer?

            Asked 2022-Jan-21 at 19:20

            digging in the ipyleaflet code, it seems that the shadow is mandatory as it's only set in this css file. The different options are set in the js file meaning that shadow cannot be removed from python code.

            As an ugly fix I forced some css directly on the top cell before import ipyleaflet:

            How to better position Next/Back button in shiny glide, in order to eliminate large white space?
            Asked 2022-Jan-18 at 15:22

            The Shinyglide package is just what I need, using a carousel for grouped radio buttons giving the user many choices for data parsing.

            However, the "Next" (and "Back") button occupies a large white space. I'd like to shift the button in line with the glide row (see image at bottom). Does anyone know how to do this? Is there a CSS trick? Reading through the Glide manual, the only choices are "top" and "bottom".

            If moving the Next/Back button isn't possible, a secondary option is to insert (a somewhat superfluous) line of text but in line with the Next/Back buttons, to at least cover up the annoyingly large white space.

            The actual panel this is for has much more information presented than in this example, so I'm trying to make the page as clean as possible.

            Please see image at bottom that better explains what I'm trying to do.

            You could use a custom control element with custom_controls, and then have it hover over the displayed screen on the top right with a container set to absolute positioning. Setting a limited width for the container will ensure that the back button won't fly too far out.

            How do you take a screenshot of a particular widget in Tkinter?
            Asked 2022-Jan-04 at 14:52

            How do you take a screenshot of a particular widget? I keep on getting "how to take screenshot of whole screen" or "how to take screenshot of the window" when searching, but I want to know how to take screenshot of a widget, a Frame, to be exact. I'm afraid that this forum would require me to give them a code snippet, when in reality I don't know what to do. So I'm just asking if this is possible, and how to do it.

            PS: I would really appreciate if it is possible to just give a function the widget variable, and then it would go searching for that widget and then take a precise screenshot of it. I know that there is pyautogui which searches for images, I just don't know what I need to do exactly, since this frame isn't an image and it always changes from now and then, so the automation might get confused.

            It's not a bug. As I remember, the "onTap" callback of PopupMenuItem calls Navigator.pop to close the Popup. In that case, when you tap on the PopupMenuItem and call "showDialog", the dialog will be popped immediately, and leaves the Popup open.

The problem is that the painted pointer remains at that exact position because the decoration is painted once inside the widget and never changes.

            Original answer

            This happens through the use of a build system. Usually in Gnome, this is the Meson Build System (before it was Autotools).

            As a very simplified explanation, this tool, when run, will look at the various meson.build files (for example, this one for the views) and build a Makefile to build the project. Inside these files, dependencies between files and resources are described. In reality, there is much more to Meson than this, and I encourage you to read about it.

            This is the meson.build file residing under the gui directory:
