AthensCairoCanvas>>setPaint: receiving a "Color transparent"

hernanmd
I am using stable branch of Roassal2 in Pharo 5 and Win 8.1 to draw a figure for a paper (but the problem is the same loading the latest versions SmalltalkHub).

When trying to open a grapher, I get a yellow-cross red morph window inside #setPaint: . The transparent color passed as argument came from AthensCairoSurface>>clear

The same figure used to open without problems some months ago.

All the Roassal examples open without problems. That's why here is the link to the fuel out stack with the halt previous to the crash : https://dl.dropboxusercontent.com/u/103833630/Debugger-Stack-AthensCairoCanvas-2017-02-15-192251.zip

Is this a well-known bug? Any suggestion?

Cheers,

Hernán

Hi Hernan,

I am not able to import the fuel error. I get the following:

Maybe you can share the image?
How can I reproduce your error?

Hi Alex,

I have uploaded an image to dropbox with the expression causing the hang, here is the link:

Hi Hernán,

I am not able to reproduce your problem since I cannot open your image (I use OSX), and apparently there is a problem with the font. I cannot open a code browser.
However, I suspect that the problem is that a nil value is used as a color.

Check this:

v := RTView new.
shape := RTBox new color: nil.
v add: shape element.
v

Executing this code seems to produce the same error. Maybe you want to add a check on your side?

Cheers,
Alexandre

Re: AthensCairoCanvas>>setPaint: receiving a "Color transparent"

Hi Alex,

I think this is too deep into Trachel and Athens. I am debugging the TRMorph>>drawOn: method and there is no way I can figure out which one of my Grapher objects should I change its color. The trachelCanvas has 22385 shapes, how they match with my higher-level grapher object?.

However, I "solved it" by lazy initializing TRShape>>color to Color transparent and then adding self color in setPaint:

TRAbstractBoxShape>>drawOn: athensCanvas
    self shouldBeDrawn
        ifFalse: [ ^ self ].
    athensCanvas pathTransform
        restoreAfter: [
            athensCanvas pathTransform
                multiplyBy: matrix asFloatTransform.
            athensCanvas
                setPaint: self color;
                drawShape: self path.
            self drawStrokeIfNecessaryOn: athensCanvas ]

Hi, 
I traced this back to RTLegendColorItem, that is initialized with "population Color" but that is nil in your  model

Thank you Nicolai.

I thought is was not possible to go from trachel objects to grapher objects, I will check with debugger again, and my model.
Cheers,

Hernán
