I just tried it out at now it is definetly faster. It
is fast enough to be usable. The dragging is still a bit slow but that matter of seconds
not minutes as before. Would it be possible to have a scrollable visualization instead of
a draggable one?
Having scrollbars is on our todos for a long time. Juraj will implement one on some
point.
In the meantime, have you tried the minimap? This is pretty cool.
Doit the following and press the key m:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
"Source code: ROMondrianExample>>miniMapOn:"
"Preambule. It includes the initialization. "
| view rawView |
rawView := ROView new.
view := ROMondrianViewBuilder view: rawView.
"-------------"
"-------------"
view raw @ (ROMiniMap new targetView: view stack).
"press m to open the view minimap "
view shape rectangle
width: [ :cls | cls numberOfVariables * 5 ];
height: #numberOfMethods;
linearFillColor: #numberOfLinesOfCode within: Collection withAllSubclasses.
view interaction popupText: [ :cls |
cls name, (String with: Character cr),
cls methods size printString, ' methods', (String with: Character cr),
cls instVarNames size printString, ' variables', (String with: Character cr),
cls numberOfLinesOfCode printString, ' LOC' ].
view interaction action: #browse.
view nodes: Collection withAllSubclasses.
view edgesFrom: #superclass.
view treeLayout.

"Below is the initiation of the menu and opening the visualization"
ROEaselMorphic new populateMenuOn: view.
view open

Stupid problem it was. The ROView object keeps a
list of elements that are visible within the window. In the drawing loop, the view
iterates over each elements and check if the element is visible before drawing it.
However this is completely unnecessary.
why? because when you explain it it looks something smart to do :)
But there are still some optimizations to be done

https://www.iam.unibe.ch/mailman/listinfo/moose-dev Hi Fabrizio,
Can you try again?
It should be significantly faster, even though we are still rendering elements that are
not visible.
Cheers,
Alexandre

opens in 1 second but that I cannot touch is useless. I tried to open a name cloud

open up but than even to display a popup window with a mouse over an element take seconds.
Not to mention that I cannot scroll the view or I have to wait minutes sometimes.
