OK so years ago I wrote a package that uses for better words a grid control , not necessarily connected to a data base directly but filled with the result of a querry. If the user clicked on a line it presented a smaller form that allowed the user to edit the data in the form and save if allowed, subject to user access rights with in the program.
DOES IT EXIST YET???
it’s been in the roadmap for quite some time now …
It really depends on what you want to do and your OS. Both PiDog Software and Graffiti Suite have a listbox like grid. On macOS you can use NSTableView from the MBS plugin, too. NSTableView also lets you use containers in a listbox. You can then use popovers for editing.
I have made a filter where I can add and remove fields out of some code that was originally for areas that can be opened and closed (StackView). More recently I did something grid like in html because I needed a listbox with variable heights. I still have to finish that.
I also once tried to make such a grid for containers:
I vote for PiDog. It has everything that grids in frameworks costing 10x as much have.
