identifying Exception classes
by Nicolas Anquetil 22 Aug '12

22 Aug '12

It seems there is no way to identify classes (java) that are Exceptions. Even the one that are used. There are ThrownException / DeclaredException / CaughtException , all pointing to the exceptionClass, but there is no opposite property in the exception class that one could use to test whether a given class is used as an exception. So the only way is to test whether Exception is an ancestor of a given class ? nicolas

Roassal hover popup on edges
by Ben Coman 21 Aug '12

21 Aug '12

With the following script, in Mondrian when you hover over edges a popup appears showing the name of the edge. Is the same possible with Roassal? view shape rectangle size: 20. nodes := view nodes: (1 to: 20). view edges: (2 to: 20) from: 1 to: #yourself. view circleLayout. cheers, Ben

ROMondrianViewBuilder versus native Roassal
by Ben Coman 20 Aug '12

20 Aug '12

Is there anything (at all) to gain in my continuing to use ROMondrianViewBuilder versus "native" Roassal? Is ROMondrianViewBuilder "just" for backward compatability to ease the transition and draw people into the new system? Or... is there stuff that ROMondrianViewBuilder does better than "native" Roassal - in terms of conciseness, ease of use, flexibility, access to layouts, features, etc... I am trying to determine whether putting effort into the perhaps easier step of going from Mondrian to ROMondrianViewBuilder may be wasted leaving me missing out on any new power of Roassal, or require more effort later to rework for native Roassal. You may have gone over this before, but how do the purpose and architecture of the two differ? cheers -ben

Roassal internals >> ROShape>>removeShape:
by Ben Coman 20 Aug '12

20 Aug '12

Just recording a bit of my learning the internals of Roassal, since it helps me flesh out my understanding. [ROShape>>removeShape:] does not have a test to reference for my understanding of this, but it appears to not work as expected. For example in workspace... b := ROBox new. c := ROCircle new. b addLast: c. b removeShape: ROCircle. b inspect results in a linked list of: aROBoxShape --> aROCircleShape --> aROChildrenShape. Actually the semantics of [removeShape:] seem problematic. What should be the result of... b := ROBox new. b removeShape: ROBox. b inspect. I would guess that 'b' should hold aROChildrenShape, except you can't change the value of 'b' from inside the [removeShape:] method. (In my limited knowledge of 'slots', I wonder if this is something they might help with.) I am relying on the guess that you could have aROChildrenShape as the only shape on an element, for subviews without a border, but could you clarify this. Naively I thought to just try... removeShape: aShapeClass ^ (self isKindOf: aShapeClass) ifTrue: [ next become: next next ] ifFalse: [ next removeShape: aShapeClass ] but the danger of #become hit me and locked my image. btw, something else just while I am feeling evil, what should happen with the following... b := ROBox new. b removeShape: ROChildrenShape. b inspect. cheers -ben

Running CodeCity in Pharo?
by Torben Knerr 20 Aug '12

20 Aug '12

Hi everybody, is there a Pharo port of Code City? I am wondering because the use of VisualWorks Smalltalk and the license restrictions that come with it make it impossible to use Code City in a commercial setting (if I understand it right). Cheers, Torben

popUpView in Roassal
by Usman Bhatti 19 Aug '12

19 Aug '12

Hello all, I'm having trouble to apply proper layout in popUpView in Roassal. The problem can be seen with the output of the following scripts: both manipulating same entities, the first one drawing entities without popUp (and producing correct layout), the second one is using popUpView (problem with the produced layout): myView := ROMondrianViewBuilder new. myView node: 'test' forIt: [ myView shape rectangle. myView node: #innerNode forIt: [ myView shape rectangle. myView node: #first forIt: [ myView nodes: #(1 2 3) ]. myView shape rectangle. myView node: #second forIt: [ myView nodes: #(1 2 3) ]. myView shape rectangle. myView node: #third forIt: [ myView nodes: #(1 2 3) ]. myView verticalLineLayout center ]. myView gridLayout ]. myView open ========================================================== view := ROMondrianViewBuilder new. view shape label. view interaction popupView: [ :entity :myView | myView node: 'test' forIt: [ myView shape rectangle. myView node: #innerNode forIt: [ myView shape rectangle. myView node: #first forIt: [ myView nodes: #(1 2 3) ]. myView shape rectangle. myView node: #second forIt: [ myView nodes: #(1 2 3) ]. myView shape rectangle. myView node: #third forIt: [ myView nodes: #(1 2 3) ]. myView verticalLineLayout center ]. myView gridLayout ]. ]. view nodes: #(0 9 8). view open Could you please see if there is a bug or I am doing it wrong? tx, Usman
