ColorButton example with Parameter Tree?

[JMA 1]

I'm new to the package and python, which means I'm struggling a bit.  When trying the parameter_tree.py, the color button that is a child parameter does not specify a valid color.  When launched, the icon on the r.h.s of the parameter value indicates it's a changed value.  What is the valid syntax for applying a number?  When using the color-picker, it generates a color object not a number.  

examples:

{ 'name' : 'Coplor', 'type' : 'color', 'value' : "FF0", },

child.setValue( format??? )

"FF0", "0xFF0", "#332211", etc. do not seem to be the correct format

Any ideas?  

Thank you in advance.

Cheers,

Welcome to pyqtgraph!

The arguments for color value can be any valid argument for pyqtgraph.functions.mkColor. Here's the docstring for that function:

    """
    Convenience function for constructing QColor from a variety of argument types. Accepted arguments are:
   
    ================ ================================================
     'c'             one of: r, g, b, c, m, y, k, w                      
     R, G, B, [A]    integers 0-255
     (R, G, B, [A])  tuple of integers 0-255
     float           greyscale, 0.0-1.0
     int             see :func:`intColor() <pyqtgraph.intColor>`
     (int, hues)     see :func:`intColor() <pyqtgraph.intColor>`
     "RGB"           hexadecimal strings; may begin with '#'
     "RGBA"          
     "RRGGBB"      
     "RRGGBBAA"    
     QColor          QColor instance; makes a copy.
    ================ ================================================
    """

Hope that helps!

Also, if you're converting numbers into colors you may find pyqtgraph.functions.intColor to be useful.
