[reportlab-users] suggested patch to reportlab.platypus.paragraph._drawBullet

[Harald Armin Massa]

Hello,

in an actual projet I ran into the challenge to have the bullet text "moved
up" a little ... the bullet is a smaller fontsize ZapfDingbats-chr(110)
[=filled square], which must be pushed "higher" to be centered with the
text.

The required changes are minimal:

def _drawBullet(canvas, offset, cur_y, bulletText, style):
    '''draw a bullet text could be a simple string or a frag list'''
    tx2 = canvas.beginText(style.bulletIndent, cur_y)
    #tx2.setFont(style.bulletFontName, style.bulletFontSize) # replace this
version by
    tx2 = canvas.beginText(style.bulletIndent,
cur_y+getattr(style,"bulletOffsetY",0))
    tx2.setFillColor(hasattr(style,'bulletColor') and style.bulletColor or
style.textColor)
    if isinstance(bulletText,basestring):
        tx2.textOut(bulletText)
    else:
        for f in bulletText:
            tx2.setFont(f.fontName, f.fontSize)
            tx2.setFillColor(f.textColor)
            tx2.textOut(f.text)

    canvas.drawText(tx2)
    #AR making definition lists a bit less ugly
    #bulletEnd = tx2.getX()
    bulletEnd = tx2.getX() + style.bulletFontSize * 0.6
    offset = max(offset,bulletEnd - style.leftIndent)
    return offset


style grews a new possible attribute "bulletOffsetY", which makes it
possible to offset the bullet-text up and down.

this patch is put into public domain, and I would be very honoured if it
gets integrated into core reportlab.

Harald
