Hi, There are a lot of videos on youtube about pharoâ¦ from conferences, demos, jamesâ Smalltalk4U, fosdem, ESUG, and others. I am (very slowly) adding playlists for all of them to the Pharo Youtube channel: https://www.youtube.com/channel/UCp3mNigANqkesFzdm058bvw/playlists If you have videos that you want to see added, send me a mail. The channel itself is here: https://www.youtube.com/channel/UCp3mNigANqkesFzdm058bvw It could use some more subscribers ;-) Marcus

Multiple-selection drag-and-drop
by Martin Dias Feb. 24, 2014

Feb. 24, 2014

Hi, I'm looking for a "kind-of-list" spec model (or morph) in Pharo 3 that supports multiple-selection drag-and-drop. I tried with TreeModel, NewListModel and ListModel... they don't support. Note: NewListModel even doesn't support single-selection drag-and-drop... is this a known issue or should I report it? Thanks, MartÃn

At the moment I'm moving, so I have very little time to do something about it. Current state is described in a thread from end of last year: http://forum.world.st/have-a-question-for-morphic-Designer-in-pharo-td47313… Stephan

Drag&drop on a button
by Martin Dias Feb. 24, 2014

Feb. 24, 2014

Hi, I wonder if either there is something wrong in my code below, or if I found a bug in morphic or spec. I expect to get a halt when drag&dropping an item from the tree into the button but nothing happens: | buttonModel treeModel ui uiLayout | ui := DynamicComposableModel new. treeModel := ui newTree roots: (1 to: 15); dragEnabled: true; yourself. buttonModel := ui newButton label: 'Drop here'; dropEnabled: true; icon: Smalltalk ui icons smallAddIcon; action: [ self halt ]; acceptDropBlock: [ self halt ]; wantDropBlock: [ self halt ]; dragTransformationBlock: [ self halt ]; yourself. ui assign: treeModel to: #treeModel. ui assign: buttonModel to: #buttonModel. uiLayout := SpecLayout composed newColumn: [ :column | column newRow: #treeModel; newRow: #buttonModel height: ui class buttonHeight ]; yourself. ui openWithSpecLayout: uiLayout. Thanks, MartÃn

SysLogSender / UDP
by Pharo4Stef Feb. 24, 2014

Feb. 24, 2014

Hi all Iâm integrating the SysLogSender of Goran as an extension of SystemLogger and my system gets blocked when I try to send something. I just did the same as in the original version (and know nothing about upd and port). I suspect that on mac is not working the same. https://developer.apple.com/library/mac/documentation/macosx/conceptual/bps… Does any of you have some ideas? my code look like that: | logger | logger := SysLogSender new addHost: 'localhost' port: 514. Log dispatcher addLogger: logger. Log dispatcher startAllLoggers. send: message to: host port: port "Send formatted UDP message to host and port." | sock | sock := Socket newUDP. sock setPeer: NetNameResolver localHostAddress port: port. sock sendData: message. sock waitForSendDoneFor: Socket standardTimeout. sock close Stef

LargePositiveInteger indexIfCompact isZero (inconsistency)
by Martin Dias Feb. 24, 2014

Feb. 24, 2014

Hi, I found this comment in TBehavior>>indexIfCompact : "Verify if the compactClassesArray and indexIfCompact are coheren Smalltalk compactClassesArray doWithIndex: [:c :i | c == nil ifFalse: [c indexIfCompact = i ifFalse: [self halt]]] " Since it *does* halt, I rewrote to: | inconsistencies | inconsistencies := OrderedCollection new. Smalltalk compactClassesArray doWithIndex: [ :class :index | class ifNotNil: [ class indexIfCompact = index ifFalse: [ inconsistencies add: { class. index. class indexIfCompact } ]]]. inconsistencies."---> an OrderedCollection({LargeNegativeInteger. 4. 0} {LargePositiveInteger. 5. 0})" I checked that in Pharo 2 they are consistent, so I guess this should be fixed. I ignore deep vm internals so... how would you fix this? I tried to #becomeUncompact to then #becomeCompact again, but it didn't work out-of-the-box. Cheers, MartÃn

ScrollPane vs. GeneralScrollPane
by Sean P. DeNigris Feb. 24, 2014

Feb. 24, 2014

GeneralScrollPane's class comment says "A scroll pane that handles its contents accurately". As opposed to what? Was it intended as a replacement for ScrollPane, or does it cover a different case? Also, the examples show scrolling a single Morph that is too big for the container, which is easy, but for a list requires creating an extra morph (not a big deal). "GeneralScrollPane new scroller" returns a TransformWithLayoutMorph, which is "A transform morph that allows the use of a layout policy to arrange submorphs". That sounds like I could do something like: s := GeneralScrollPane new. s scroller changeTableLayout. (1 to: 50) do: [ :e | s scroller addMorphBack: (SimpleObjectMorph on: e ) ]. s openInWindow. Although it lays out the object morphs vertically in the scroll pane, there is a blue morph above them and the scroll bars only appear when the pane is smaller than this morph. ----- Cheers, Sean -- View this message in context: http://forum.world.st/ScrollPane-vs-GeneralScrollPane-tp4743443.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
