Maybe I don't understand what you're doing, but it seems a rather clumsy
way to center vertically.
Here is a fragment from a script I wrote to center text vertically in a
frame by adjusting the Top text distance value. This is the logic part
that centers the text in the frame. It requires fixed linespacing to
work properly.
lines = scribus.getTextLines(textbox)
distances = scribus.getTextDistances(textbox)
linespace = scribus.getLineSpacing(textbox)
dimensions = scribus.getSize(textbox) # (width, height)
if (scribus.textOverflows(textbox, 1) > 0):
scribus.messageBox('User Error', "This frame is already
overflowing", scribus.ICON_WARNING, scribus.BUTTON_OK)
sys.exit(2)
newtopdist = (dimensions[1] - linespace * lines)/2
scribus.setTextDistances(distances[0],distances[1],newtopdist,distances[3],textbox)
scribus.moveObject(-4,0,textbox)
scribus.moveObject(4,0,textbox)
The last 2 lines compensate for a display problem in Scribus. If they're
not there you may not see the text shifted as it should. It's only a
display problem, since if you save your document and reload, you see the
text shifted. I also noted that if you move the frame, the text moves in
the display to where it should be, so the script has a built-in shift,
then unshift to manage the same thing.
