Re: [Win32lib] setPenColor

Since no one responded to my last blurb about this, I put a printf() behind
every call to xSelectObject() in win32lib,
then ran the following code in both an onOpen[], then an onPaint[], with
conflicting results.
In an onOpen[], there were 8 calls to xSelectObject(), as I expected, but in an
onPaint[], there were only 5 ( per
'paint' event ).
If the 'rule' regarding SelectObject() is to be taken literally, should the
results not be the same ???

< An application should always replace a new object with the original, default
object after it has finished drawing with
the new object. >

This is clearly happening in an onOpen[], so why not an onPaint[] ?
Perhaps someone could enlighten me ...

-- simple code --
setPenColor(w,Red)
drawLine(w,10,10,120,120)
setPenColor(w,Green)
drawLine(w,10,10,40,140)
setPenColor(w,Blue)
drawLine(w,10,10,140,10)
setPenColor(w,Black)
drawLine(w,10,10,60,100)
