How can I calculate the current size of a Screen frame?

[SypherZent]

I have a screens code, like this:

Code: Select all

screen New_screen():

    frame:
        background None
        align (0.5,0.5)
        xmaximum 300

        text "This is a long string of text confined to a small frame and I want to know the exact height of the resulting frame, given font and text size."

   # I want to retrieve the height of that frame on this line of code, and store it in a variable

How can I calculate the height of that frame? Is it possible to give it an ID and call it in the same screen somehow?

Thanks.

Really depends what you need it for, and hope to do with it. I strongly advise against using this in anything outside of debugging and/or toy projects, but here is one possible way to get that information:

Code: Select all

label start:
    show screen New_screen()
    '[frame_size] var not available until next interaction'
    'frame size: [frame_size]'
    return

init python:
    def save_size(f):
        store.frame_size = f.window_size

screen New_screen():
    frame as myframe:
        background None
        align (0.5,0.5)
        xmaximum 300
        text "This is a long string of text confined to a small frame and I want to know the exact height of the resulting frame, given font and text size."

    timer .00001 action Function(save_size, myframe) # window_size isn't set until after render, so cheese it with a timer
