Relative placement of child group fails #12

Closed hchauvet closed 6 years ago

hchauvet commented 6 years ago

Placement of a child group relative to it's parent fail. The following code produces an error:


with slide('test group relative position'):

    with group(x='center', y='center') as g1:
        text('inside first group')

        with group(x=g1.left+0, y=g1.bottom+0):
            text('inside second group')

This is a bug in the slide.newrender() method, where distribute() function is called as the parents position is not resolved because the group size is not yet known.

To solve it perhaps we need to introduce a recursive position solver in the positionner class...

This issue is partially fixed in version 0.4.8 with the commit: 7daca02

It is partially solved, because refering to a parent group with positions set to 'auto' or 'center' and width or height set to None can't be done accuratly, as we need to place the child group to compute parent group width or height and place it.

The fix, print a warning for this situation, and use the slide.curwidth as width and document._height as height. This will allow to compile the presentation but with unexpected parent group position.
