I'd like to make a grid of drag and drop displayables of dynamically generated text, with background images.

The following doesn't work:

Code:

init python:
    from string import ascii_letters

    caps = ascii_letters[26:]
    
    def puzzle_screen(grid_size=8, **kwargs):
        ui.grid(grid_size, grid_size, id='puzzle_grid')
        for i in caps[0:grid_size]:
            for j in range(grid_size):
                drag_id = i + str(j)
                drag_child = ui.textbutton(drag_id, id='_' + drag_id, xminimum=50, yminimum=50, xpadding=0, background='rectangle.png')
                ui.drag(d=drag_child, drag_name=drag_id, id=drag_id)
        ui.close()
    renpy.define_screen('puzzle_screen', puzzle_screen)

Code:

Exception: Widget <renpy.display.dragdrop.Drag object at 0x03441230> expects a child.

How should I pass a child to ui.drag()?

And, is there a better way to create a displayable of text with background then ui.textbutton()? Should I create a custom displayable?

1) You're not going to be able to put ui.drags inside a grid. Well, it will work, but it'll be pointless. Drags position themselves relative to the enclosing area, which are the cells of the grid - so a drag in a grid won't move. You want to create a drag, and then call snap on it to put it into the grid.

2) For ui.drag, you want to omit the d parameter, and call ui.textbutton directy. So the code would look like:

Code:

    drag = ui.drag(drag_name=drag_id, id=drag_id)
    drag.snap(x, y)
    ui.window(xminimum=50, yminimum=50, xpadding=0, background='rectangle.png')
    ui.text(drag_id)
