# Here's how this works: near the top of the file there are a bunch of
# functions that call setColor with a hex color code. All the functions
# in this file show up as separate macros in LibreOffice. So, just copy the
# file into your LibreOffice macros directory and then assign keyboard shortcuts
# to the colors you care about, as well as to showPen and hidePen. If you want
# to add colors, just copy one of the functions and change the color code.

import uno

# define colors here, just copy a function,
# change its name, and change the color. They're in
# HTML hex color format, first two bytes are red, then green,
# then blue

# each function shows up as an individual macro under My Macros -> Pen in
# LibreOffice

def red():
    setColor(0xff0000)

def green():
    setColor(0x00ff00)

def blue():
    setColor(0x0000ff)

def black():
    setColor(0x000000)

def white():
    setColor(0xffffff)

def purple():
    setColor(0xbb00bb)

def yellow():
    setColor(0xfff000)

def cyan():
    setColor(0x00ffd8)

def orange():
    setColor(0xff5e00)

## End definitions of colors
def getPresentation():
    return XSCRIPTCONTEXT.getDesktop().getCurrentComponent().getPresentation()

def setColor(color):
    if color < 0 or color > 0xffffff:
        return

    # TODO: What if it's not a presentation?
    pres = getPresentation()

    if pres.isRunning():
        pres.getController().PenColor = color

def showPen():
    pres = getPresentation()
    if pres.isRunning():
        pres.getController().UsePen = True

def hidePen():
    pres = getPresentation()
    if pres.isRunning():
        pres.getController().UsePen = False

    

Congratulations for the good work! This macro is going to be useful for me! :)

I installed it using the instructions given here, so I can find it on Tools -> Macros -> Organize macros -> Python. Also, I assigned key shortcuts to some of its functions, as seen here, but I can't get them to work... =/

Do you know whether your macro works on LibreOffice 4.3.5?
