[Glamour] default selection in ListPresentation
by Cyrille Delaunay
Hello,
Is there a way to set a default selection to a list presentation? so that
when I open the browser, the morphic list has already a value selected.
I tried that:
|tmpBrowser|
tmpBrowser := GLMTabulator new.
tmpBrowser row: #list.
tmpBrowser transmit to: #list; andShow: [:a |
a list
display: [:input | input];
selection: #a;
yourself
].
tmpBrowser openOn: #( b c d v a d f r).
but the list still open with nothing selected

Theme aware-ish TRMorph
by Peter Uhnák
Hi,
since I wanted to use DarkTheme I played around with TRMorph (since seeing
giant white rectangle in dark theme is not very nice).
What I have done is moved the background color setting to `surface clear:`
(instead of the original aCanvas fillRectangle).
And then if theme background luminance is dark (>0.5), I invert all the
colors in the visualization.
For dark theme the background is black, and not the theme background - at
least to me it seems that black is much clearer.
Is this something that could be incorporated?
And the modified code:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
"protocol: drawing"
TRMorph>>drawOn: aCanvas
"aCanvas is a FormCanvas"
self checkSession.
"aCanvas fillRectangle: bounds color: trachelCanvas color."
trachelCanvas playAnimations.
"The drawing has to be done when a change in the shapes occured or when
there is an animation."
surface drawDuring: [:cs |
surface clear: trachelCanvas color.
"We display the elements that are subject to the camera"
cs pathTransform
translateBy: (self extent / 2) asFloatPoint;
scaleBy: trachelCanvas camera scale asFloat;
translateBy: trachelCanvas camera position negated asFloatPoint.
trachelCanvas shapes do: [ :trachelShape |
trachelShape drawOn: cs.
].
"We display the elements that are _NOT_ subject to the camera"
cs pathTransform loadIdentity scaleBy: 1.001.
trachelCanvas fixedShapes do: [ :trachelShape |
trachelShape drawOn: cs.
].
].
self theme backgroundColor luminance < 0.5 ifTrue: [
surface drawDuring: [ :cs |
cs paintMode restoreAfter: [
cs setPaint: Color white.
cs paintMode difference.
cs drawShape: (0 @ 0 extent: surface extent)
]
]
].
"aCanvas translucentImage: surface asForm at: self bounds origin."
"asForm creates a new Form, which is likely to be expensive. This can be
cached"
aCanvas image: surface asForm at: self bounds origin sourceRect: (0 @ 0
extent: surface extent) rule: 34.

broken Roassal2Spec Adapter
by Peter Uhnák
Hi,
apparently we broke MorphicRoassalAdapter when cleaning Spec, I attached a
fix.
However my question is - does anybody (except us) actually use the
Roassal2Spec package? Because otherwise we could clean it a bit. For
example I'm not sure of the use case of script:/lastEvent:.

Parallel coordinates like diagram
by Manfred Kröhnert
Hi everyone,
some time ago I saw a diagram consisting of two columns of words and lines
showing associations between the words in both columns.
It looked similar to the "parallel coordinates" diagram from this link:
http://homes.cs.washington.edu/~jheer/files/zoo/ but with only two columns.
Now, I am not sure if I saw this in an email on a Pharo or Moose list and
wanted to ask if it is already possible to create such diagrams with
Roassal.
Thank you very much,
Manfred

Weird lines implementation
by Yuriy Tymchuk
Hi everyone,
I guess because of a rapid evolution some parts of Roassal are weird. For example RTAbstractLine>>#updateFor:trachelShape: implements the shape drawing, so theoretically RTLine has to only override #trachelShapeClass to return TRLine. Instead RTLine overrides #trachelShapeFor: and does it incorrectly, because width cannot be used as a block but only as a number.
We have to handle this somehow, because 1) RTLine works incorrectly. 2) RTLine ignores the implementation strategy coded into RTAbstractLine.

Following the mouse cursor in Grapher
by Alexandre Bergel
Hi!
I relaxed a bit by implementing something that was missing in Grapher.
Consider the following code:
-=-=-=-=-=-=-=-=-=-=-=-=
b := RTGrapher new.
ds := RTDataSet new.
ds points: #(5 10 6 2 -2.5).
b add: ds.
“below is the magic line"
b addDecorator: RTCursorFollower new.
b
-=-=-=-=-=-=-=-=-=-=-=-=
This “magic line” add two bar that follows the mouse cursor. Here is a screenshot:
Here is on a larger example:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
| methods trachelMethods b ds |
methods := Collection withAllSubclasses flatCollect: #rtmethods.
trachelMethods := TRObject withAllSubclasses flatCollect: #rtmethods.
b := RTGrapher new.
b extent: 200 @ 200.
"Data set 1"
ds := RTDataSet new.
ds interaction popup.
ds dotShape circle color: (Color red alpha: 0.3).
ds points: methods.
ds x: #numberOfLinesOfCode.
ds y: [ :m | m getSource size ].
b add: ds.
"Data set 2"
ds := RTDataSet new.
ds interaction popup.
ds dotShape circle color: (Color blue alpha: 0.3).
ds points: trachelMethods.
ds x: #numberOfLinesOfCode.
ds y: [ :m | m getSource size ].
b add: ds.
b axisX withThousandsSeparator; title: 'LOC'.
b axisY noDecimal; title: 'Size'.
b addDecorator: RTCursorFollower new.
b build.
^ b view
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
Maybe this cursor follower should be per default in all produced chart. Any opinion?
Cheers,
Alexandre

Re: [Pharo-dev] GanttChartMorph openOn: aCollectionOfActivities ?
by Alexandre Bergel
Hi Hannes!
Here is a first shoot paired-programmed with Juraj using Roassal:
-=-=-=-=-=-=-=-=-=-=-=-=
b := RTTimeLine new.
b addEntry: (RTTimeLineEntry new identifier: #WP1; start: 0; end: 5).
b addEntry: (RTTimeLineEntry new identifier: #WP2; start: 5; end: 8).
b addEntry: (RTTimeLineEntry new identifier: #WP3; start: 7; end: 10).
b axisX numberOfLabels: 5.
b
-=-=-=-=-=-=-=-=-=-=-=-=
Here some slightly more elaborated example:
-=-=-=-=-=-=-=-=-=-=-=-=
“One color per entry"
| b d |
b := RTTimeLine new.
b addEntry: (RTTimeLineEntry new identifier: #c1; start: 0; end: 5).
b addEntry: (RTTimeLineEntry new identifier: #c1; start: 6; end: 8).
b addEntry: (RTTimeLineEntry new identifier: #c2; start: 0; end: 5).
b addEntry: (RTTimeLineEntry new identifier: #c2; start: 8; end: 10).
b addEntry: (RTTimeLineEntry new identifier: #c3; start: 0; end: 10).
b addEntry: (RTTimeLineEntry new identifier: #c4; start: 5; end: 10).
b addEntry: (RTTimeLineEntry new identifier: #c5; start: 5; end: 8).
d := RTVerticalTickLineDecorator new.
d shape line color: Color white.
b addDecorator: d.
b axisX
numberOfLabels: 5;
labelRotation: -45;
labelConversion: [ :v | Date year: 2015 day: v ].
b shape color: (RTMultiLinearColorForIdentity new objects: b entries).
b
-=-=-=-=-=-=-=-=-=-=-=-=
One color per timeline
-=-=-=-=-=-=-=-=-=-=-=-=
| b |
b := RTTimeLine new.
b addEntry: (RTTimeLineEntry new identifier: #c1; start: 0; end: 5).
b addEntry: (RTTimeLineEntry new identifier: #c1; start: 6; end: 8).
b addEntry: (RTTimeLineEntry new identifier: #c2; start: 0; end: 5).
b addEntry: (RTTimeLineEntry new identifier: #c2; start: 8; end: 10).
b addEntry: (RTTimeLineEntry new identifier: #c3; start: 0; end: 10).
b addEntry: (RTTimeLineEntry new identifier: #c4; start: 5; end: 10).
b addEntry: (RTTimeLineEntry new identifier: #c5; start: 5; end: 8).
d := RTVerticalTickLineDecorator new.
d shape line color: Color white.
b addDecorator: d.
b axisX
numberOfLabels: 5;
labelRotation: -45;
labelConversion: [ :v | Date year: 2015 day: v ].
b shape color: (RTMultiLinearColorForIdentity new command: #identifier; objects: #(c1 c2 c3 c4 c5)).
b
-=-=-=-=-=-=-=-=-=-=-=-=
Age of some classes:
-=-=-=-=-=-=-=-=-=-=-=-=
| b |
b := RTTimeLine new.
b extent: 500 @ 500.
((RTShape withAllSubclasses sortedAs: #ageInDaysRounded) select: #hasMethods)
do: [ :cls |
e := RTTimeLineEntry new.
e identifier: cls.
e start: cls computeYoungestMethod ageInDays.
e end: cls computeOldestMethod ageInDays.
b addEntry: e ].
b
-=-=-=-=-=-=-=-=-=-=-=-=
All these examples are in the Roassal time line example menu.
This is still an early version. Let us know how it goes!

DeepTraverser
by Nicolas Anquetil
Anybody can explain the changes that occured over DeepTraverser ?
(Ideally how can we switch from old to new traverser?)
We have an "old" (1 year) bit of code that use the deepCollect: method
However, the changes in DeepTraverser break our code :-(
