html - QTextBlockFormat.setLeftMargin(1em): How To? -


in html-list bullets, on change of fontsize via format.setfontpointsize() bullets drive out of editor. figured out bullets stay on same position on fontsize-change if set padding-left 1em (tried in html-editor). how can achieve list entry in qt? can set pixel value , not element value?

        fmt=cur.charformat()         charsize=fmt.fontpointsize()         if charsize==0.0:             charsize=14         if direction=="up":             fmt.setfontpointsize(charsize+1)             if textlist:                     blockformat=cur.blockformat()                     #blockformat.setleftmargin(blockformat.leftmargin()+0.4)                     blockformat.setleftmargin(1em)                     cur.mergeblockformat(blockformat)         else:             fmt.setfontpointsize(charsize-1)             if textlist:                     blockformat=cur.blockformat()                     #blockformat.setleftmargin(blockformat.leftmargin()-0.4)                     blockformat.setleftmargin(1em)                     cur.mergeblockformat(blockformat)         cur.mergecharformat(fmt)

you can set default indentation text lists in qtextdocument instance creating (i think default 40). multiples of value used each indentation level in list.

qtextdocument *doc = new qtextdocument(); doc->setindentwidth(20);  qtextcursor *cursor = new qtextcursor(doc);  qtextlistformat listformat; listformat.setindent(1); // first indent level, indent 20 cursor->insertlist(listformat); // insert items list  listformat.setindent(2); // second indent level, indent 40 cursor->insertlist(listformat); // insert nested list items
