Hi, GLMCompositePresentation does not understand #wrapper anymore in P8 (valid in P7). More, the class GLMWrapper vanished (present in P7). In DrGeo a custom script browser is build to edit script, in this browser when clicking on a script there is now this error. I tool a look to the I don't understand much this framework. How should the code bellow be rewritten to work on P8? |methodsIn: composite Â composite /*wrapper*/ title: 'Methods' translated; Â show: [ :wrapper | Â Â wrapper fastList Â Â Â display: [ :aClass | aClass methods collect: [ :m | m asRingDefinition ]]; Â Â Â format: [ :aCompiledMethod | aCompiledMethod selector asString ] ]. Â composite /*wrapper*/ title: 'Script data' translated; Â show: [ :wrapper | Â Â wrapper fastList Â Â Â display: [ :aClass | aClass class methods collect: [ :m | m asRingDefinition ]]; Â Â Â format: [ :aCompiledMethod | aCompiledMethod selector asString ] ]. Â composite Â updateOn: MethodModified from: [ SystemAnnouncer uniqueInstance ]; Â updateOn: MethodAdded from: [ SystemAnnouncer uniqueInstance ].

Hi, RubPluggableTextMorph replaced the old PluggableTextMorph. acceptOnCR: and changedAction: are not valid any more. For the former never mind. For the latter how should it be rewritten? I read these self textArea announcer when: RubTextChanged send: #whenTextChangedInTextArea: to: self. and whenTextChangedInTextArea: anAnnouncement Â Â Â self announcer announce: anAnnouncement It looks like we have both the old and new word of changes propagation. I am wondering how to propagate it in DrGeo (pre-Announcement era) Thanks newDescriptionMorph Â Â Â ^(self Â Â Â Â Â Â newTextEditorFor: self Â Â Â Â Â Â getText: #description Â Â Â Â Â Â setText: #description: Â Â Â Â Â Â getEnabled: nil) Â Â Â Â Â Â acceptOnCR: false; Â Â Â Â Â Â setBalloonText: 'A description of the script. To help the user, describe carefully what the script does and the input arguments to select to use it.' translated; Â Â Â Â Â Â changedAction: [:text | self changed: #isValid ]; Â Â Â Â Â Â selectAll -- Dr. Geo http://drgeo.eu
