ForceLayout is slow for too many elements.
by Demian Schkolnik 30 Jul '15

30 Jul '15

Hi all! I want to make a visualization of a graph (nodes and edges), but applying ForceLayout to it takes forever, because the graph has too many elements. if I apply TreeLayout, for example, the view renders almost instantly. Is there some other Layout, similar to ForceLayout, but faster, for so many elements? Thanks!

Hi, Few days ago I built a view using the class RTData. With the last version of Roassal.. puff... disappeared… I read the discussion 'New RTData class in Roassal’ and it looks is the one to use. Am I right? Cheers, R

Hello, I was checking on FAMIXSQL and there is this test class that fails becuase it depends on the PetitSQLIslandParser package. I think this class is not belong here. Can we move it into a PetitSQLIslandParser package? Thanks and cheers, Fabrizio

Conditional layout
by Alexandre Bergel 29 Jul '15

29 Jul '15

Dear all, I have created a class RTConditionalLayout and it is into the Layout Builder. Consider the following example: -=-=-=-=-=-=-=-=-= v := RTView new. es := (RTEllipse new size: 30; color: [ :value | value odd ifTrue: [ Color red ] ifFalse: [ Color blue ] ]) elementsOn: (1 to: 4). v addAll: es. l := RTConditionalLayout new condition: [ :element | element model odd ]; thenLayout: RTVerticalLineLayout new; elseLayout: RTHorizontalLineLayout new. l on: es. v -=-=-=-=-=-=-=-=-= The idea is to have a layout that segregate some elements that match a particular condition. This is supported in the Layout builder, which allows one to do (using RTMondrian in that case): -=-=-=-=-=-=-=-=-= b := RTMondrian new. b shape rectangle fillColor: Color white; borderColor: Color lightGray; withTextAbove: #name. b nodes: Collection withAllSubclasses forEach: [ :cls | b nodes: cls methods. b edges connectToAll: #dependentMethods. b layout ifElement: #isConnected then: RTTreeLayout new; else: RTGridLayout new. ]. b edges connectFrom: #superclass. b layout tree. b -=-=-=-=-=-=-=-=-= The issue here is that I have introduced a mechanism to do ‘if’ statements. I am not sure this is the best things… Comments are welcome :-) Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Rewrite of RTEdgeBuilder
by Alexandre Bergel 29 Jul '15

29 Jul '15

Dear All, RTEdgeBuilder has been completely rewritten. You can now specific objects and elements from where edges begins and edges. The API is about 70% the same I believe. Migration of your code should be fairly easy. Else, ask for help. In any case, the old builder is named: RTEdgeBuilderDeprecated Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Glamour Tabs not updated when update is called
by Gareth Cox 28 Jul '15

28 Jul '15

Hi All Not sure if this is a bug, but here goes. Looking through the Glamour examples in Pharo4 I come across the Updateable Browser example. This example has a line that, when the collection is greater than 1, shows a list tab, the title of which is List, col size printString. This indeed comes up and shows: 'List: 2' but if you continue to add, it doesn't change. The text will change but not the title. I came across this when I couldn't get my browser to add tabs, even though entity gets updated. Example from Glamour below. | browser collection| collection := GLMAnnouncingCollection new. collection add: 1. browser := GLMTabulator new. browser column: #preview. browser act: [:b | b entity add: (b entity size + 1). b update ] icon: GLMUIThemeExtraIcons glamorousAdd entitled: 'Add an item in the collection'. browser act: [:b | b entity removeLast. b update ] icon: GLMUIThemeExtraIcons glamorousRemove entitled: 'Remove last item from the collection'. browser updateOn: GLMItemAdded from: #yourself; updateOn: GLMItemRemoved from: #yourself. browser transmit to: #preview; andShow: [ :a | a list title: [:col | 'List: ', col size printString ]; *"This isn't updating"* when: [:col | col size > 1 ]. a text title: 'Text'; format: [:col | 'Current collection: ', col printString, '. Add more items to show the list'] ]. browser openOn: collection KR -- Gareth Cox IT Manager/Developer Inspired Org (PTY) Ltd email: gareth(a)inspired.org <mailto:gareth@inspired.org>

Roassal TRDrag events should be conditioned by TRMouseEnter and RTLayoutTranslator
by Peter Uhnák 27 Jul '15

27 Jul '15

Hi Alex, I think that TRDrag* events should require that you are over the dragged element with your mouse, because now the behavior is that if the mouse gets outside the element, drag events are still being fired. But maybe I should fix this on my side. To better illustrate my point look at this https://www.youtube.com/watch?v=4rHdiwGdr4s When the mouse is completely out of the element the resizing is still occurring (because the drag event is still being applied), and then compare it to the behavior of resizing Playground -- there it happens only where it makes sense. I haven't found any applicable example directly in Roassal, but you can look into my smalltalkhub peteruhnak/roassal-contrib repo (same as we used before for moving stuff from dynacase) at DCRTResizable>>example On another note: I added methods for moving to RTLayoutTranslator for all sides, so you can probably move it to Roassal if it looks ok to you. Thanks, Peter

What DCRTFocusable is about?
by Alexandre Bergel 26 Jul '15

26 Jul '15

Hi! I do not get an example with DCRTFocusable. What does this interaction do? I tried the following and it does not seem to do much. -=-=-=-=-=-= b := RTMondrian new. b shape rectangle width: #numberOfVariables; height: #numberOfMethods. ns := b nodes: RTShape withAllSubclasses. es := b edges connectFrom: #superclass. es @ DCRTFocusable. b layout tree. b -=-=-=-=-=-= Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Roassal observing click on any and all elements
by Peter Uhnák 25 Jul '15

25 Jul '15

Hi Alex, I'm trying to find a way how to observe all mouse clicks regardless of elements. I can do this easily on my side, because I have control over everything I create, but doing that would prevent certain things like RTResizable from working in pure Roassal... Currently all Trachel mouse events are created in Morphic (TRMorph), however events themselves are fired from shapes' announcers so there is no convergence point. So, would it be possible to basically fire the event twice, once from the shape's announcer and once from probably view or canvas (or some TROverseer class or whatever). As far as performance goes this shouldn't be a problem if you consider that just mouse movement can trigger 10 events every second. What do you think? Is it worth for you to change/implement it? If not I will resolve it on my side. Thanks, Peter
