Polymorph help text
by Jeff Gray June 3, 2012

June 3, 2012

I am building a UI with polymorph. It's all working well. One curious thing is that the hover help over my controls displays with a carriage return just before the last character. I'm using 1.4 on linux 64bit. Anyone else seen this? -- View this message in context: http://forum.world.st/Polymorph-help-text-tp4633024.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

how to test forked morph rendering
by Tudor Girba June 2, 2012

June 2, 2012

Hi, I have a piece of code that builds a morph in a parallel process, and I would like to test that it builds the right thing. The building of the morph can take long. My current solution is to add a delay, but this is ugly and unreliable: "setup and trigger the morph building" (Delay forMilliseconds: 1000) wait. "assert that the morph is correct" The question is if there is a better way. Cheers, Doru -- www.tudorgirba.com "We are all great at making mistakes."

ZnClient>>#close & socket semaphores
by Paul DeBruicker June 1, 2012

June 1, 2012

I ran into an out-of-external semaphores error when testing the Tropo API. It uses ZnEasy to post data to their api servers. I know I can raise the semaphore limit by running: Smalltalk vm maxExternalSemaphoresSilently: 3000. then saving. But I wondered if changing ZnClient>>#close to this: close "Close any HTTP network connection that I might have kept open." connection ifNotNil: [ connection close: self isOneShot. connection := nil. state := #closed ]. lastUsed := nil And then adding these two methods: ZdcAbstractSocketStream>>#close: close: andDestroy "Close the stream, flush if necessary" self flush. socket isNil ifTrue: [ ^ self ]. self socketClose: andDestroy. socket := nil ZdcAbstractSocketStream>>#socketClose: andDestroy andDestroy ifTrue: [ socket closeAndDestroy ] ifFalse: [ socket close ] might enable ZnClient to clean up after it issues 'one shot' requests in a safe manner. I can submit a change if so ( an a test! ). Thanks Paul

FreeTypeFontProvider current updateFromFileEntry: (FileDirectory default entryAt: 'UnDotum.ttf') directory: FileDirectory default locationType: #imageRelative. FreeTypeFontProvider current buildFamilies. FreeTypeFontSelectorDialogWindow new open. "to see the loaded font" StandardFonts balloonFont: (LogicalFont familyName: 'UnDotum' pointSize: 10). StandardFonts defaultFont: (LogicalFont familyName: 'UnDotum' pointSize: 11). Hilaire -- Dr. Geo -- http://www.drgeo.eu
