á§ And then, as if by magic, the problem vanished! I think the problem must have been something I was doing wrong at the Google end. Everything now works. Thanks Sven

Re: [Pharo-users] Roassal2 orthogonal lines, attach points and self-lines.

by Peter UhnÃ¡k

Hi Alex, I've refactored it a bit and created a RPControllable as a descendant of RTInteraction. You can see it in http://smalltalkhub.com/#!/~peteruhnak/RoassalPrototypes/ I also moved the >>resetShape method to Roassal's RTEdge as an extension package. But the way I reset the line remains quite daft. There's a simple usage example in RPControllable class side and a comment. Also there may be problems with the fact that I am basically hiding both shapes of the controlling elements and RTMultiLine. This could be solved with accessors, but my question is more conceptual - should the interaction be even responsible for creating those shapes - especially RTMultiLine? But than again RTLabelled creates Label itself too. Anyway... off to play with the grid now.

Hi, The Bootstrap wrapping project for Seaside now has also support for the Jasni Bootstrap extension (see http://jasny.github.io/bootstrap) Seaside Examples can be found on the following URL's http://pharo.pharocloud.com/bootstrap/browser/Jasny%20-%20Button%20Label http://pharo.pharocloud.com/bootstrap/browser/Jasny%20-%20Input%20Mask http://pharo.pharocloud.com/bootstrap/browser/Jasny%20-%20Navmenu Hope this is useful.

Re: [Pharo-users] Updatable trees in Moose browsers (It was Re: Rephrasing my question on Stackoverflow ...)

by Offray Vladimir Luna CÃ¡rdenas

Hi Nicolai and Doru and community, This is working like a charm. I can add an remove nodes to selected nodes on any place of the tree, as you can see in this screenshot: http://www.enlightenment.org/ss/e-53eff22637d2c7.34692752.jpg I have some questions: - I have an issue still and is that once I have deleted a particular node, its parent should be now the selected node. If this doesn't happen, deleting and adding nodes with nothing selected becomes problematic. How can I reassign the selection to a node's parent? - This is more like a curiosity on good practices. The more I write on UbakyeBrowser>>buildBrowser, the more a lateral panel becomes red. I imagine that this is related with the extension of the code and some kind of reminder for modularization. Being the tree and its behaviour the more complex part of the interface I think that is the first candidate for this to happen. There is any reading I can see for advice on this? Following the advice of Doru, here is a way to see the code and launching the last version in a default Moose: =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Gofer new smalltalkhubUser: 'Offray' project: 'Ubakye'; package: 'Ubakye'; load. UbakyeBrowser open. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Some time ago I said that I was approaching to the fun part of the Smalltalk joyride, and now if feels even closer! :-) https://twitter.com/offrayLC/status/493979407011561473/photo/1 Thanks, Offray On 08/14/2014 12:11 AM, Tudor Girba wrote: > Hi, > > The important visual objects, such as the selection, are reflected on the ports > of the pane containing the presentation. > > The tree has two ports that are relevant for selection: > - #selection will give you the selected node > - #selectionPath will give you the path from the selected node to the root > > You can do like this: > a tree > act: [:treePresentation | treePresentation selection inspect ] entitled: > 'Inspect selection'; > act: [:treePresentation | treePresentation selectionPath inspect ] entitled: > 'Inspect selection path' > > > Cheers, > Doru > > > > On Thu, Aug 14, 2014 at 1:32 AM, Nicolai Hess <nicolaihess(a)web.de > <mailto:nicolaihess@web.de>> wrote: > > Hi Offray, > > some notes about your code: > > > browser > act: [:newNode | > newNode := UbakyeNode > header: 'nuevoNodo' body: ''. > mainTree addNode: newNode.] > > this would change the block parameter "newNode", but the block parameter is > supposed to deliver the object you'll act on, the browser for example. > I think you wanted to write this code: > > browser > act: [ :b | |newNode| > > newNode := UbakyeNode > header: 'nuevoNodo' body: ''. > b entity addNode: newNode . > > if you call "b update" like you did in the "remove action" your browse tree > update will work. > > changing OrderedCollection to GLMAnnouncingCollection should work, but > you'll have to define > the appropiate announcer source #children instead of #yourself. #yourself > gives the mainTree, and that > does not work as your mainTree is not a GLMAnnouncingCollection. > > updateOn: GLMItemAdded from: #children > > There are two things I don't understand > > 1. > setting updateOn: on the browser does not work: > > browser updateOn: GLMItemAdded from: #children. > > but setting it on the tree > > (browser transmit) > to: #preview; > andShow: [ :a | > a tree > "-->" updateOn: GLMItemAdded from: #children; > > title: mainTree header; > children: [:eachNode | eachNode children ]; > > format: [:eachNode | eachNode header ]. > a text > title: 'Text']. > > > updates the tree when adding an element by the + button > > 2. is there a way to get the currently selected tree node?
