Morning….

Having a bit of trouble with a custom widget added to a column of a kivy gridlayout. I still learning kivy/kivyMD and was able to previously do this quite easily with PYQT6.

When my main page opens I’m reading a SQLite Database and loading the record contents in a gridlayout. I know you achieve this by setting the background properties for each widget added but in my case my custom widget has Buttonbehavior and an Image widget which I’m using to display and clickable image within the gridlayout. I read a posting saying you can set the background by setting the background_normal to “” and background_color to a color list but this did not work for me. I tried dynamically setting the canvas.before and canvas.after while loading the record contents but this as well messed up my screen.

What’s currently happening is the image does properly display in my gridlayout but the background color is not working. The background color for the odd row setting was originally a color list of [.78, .85, .92, 1] which also did not work.

As usual any suggestions greatly appreciated.

thanks
