inspect window not on top
by Ralph Boland 30 Sep '18

30 Sep '18

I have morph. I have implemented for that morph the method: yellowButtonActivity: shiftState ^self inspect This brings up an inspector on the morph which as expected. However, if the location of the inspector overlaps the morph, the morph covers the inspector so that the inspector is partially or totally hidden by my morph. I also tried this with a submorph of my main morph and the same thing happens. In trying to figure this out I determined that method "Morph>>morphicLayerNumber" is invoked and returns value 100. Here is the code: Morph>>morphicLayerNumber "helpful for insuring some morphs always appear in front of or behind others. smaller numbers are in front" ^(owner isNil or: [owner isWorldMorph]) ifTrue: [ self valueOfProperty: #morphicLayerNumber ifAbsent: [100] ] ifFalse: [ owner morphicLayerNumber ]. "leave lots of room for special things" I assume a value < 100 must be set for the the morphicLayerNumber for the inspector But I don't know who is supposed to do this? or how I tell "who" to do it. Every place I can find that sends <inspect> just sends the message; no preparation code for the inspect is applied. I am lost and could use some enlightenment. Thanks for your time Ralph Boland

I have an application running on Mac which I am trying to port to run on Windows. PipeableOSProcess fails on an know issue. Is Process Wrapper a viable option? It requires adding SmartSyntaxInterpreterPlugin, and ProcessWrapperPlugin.dll. All I want to do is run an .exe and capture the output. Any suggestions? - jrm

Saving the font settings
by Marc Hanisch 27 Sep '18

27 Sep '18

Hello, I'm a new Squeak user, so please be patient ;-) I'm using Squeak on a Laptop with a FullHD display. The standard font sizes are too small for my eyes and the Demo-HiDPI-theme is too large. When I adjust the fonts, is there a way to save these settings also outside the image? So that I can reload the settings with every new image without to adjust the font sizes again and again? Thanks for your replies and have a nice weekend! :-) Marc

by Holly Styles 27 Sep '18

27 Sep '18

Hi, I CTRL + d the following from the metacello githhub readme in a workspace of a fresh download of squeak on Windows 10. "Get the Metacello configuration (for Squeak users)"Installer gemsource project: 'metacello'; addPackage: 'ConfigurationOfMetacello'; install. "Bootstrap Metacello Preview, using mcz files (#'previewBootstrap' symbolic version" ((Smalltalk at: #ConfigurationOfMetacello) project version: #'previewBootstrap') load. "Load the Preview version of Metacello from GitHub" (Smalltalk at: #Metacello) new configuration: 'MetacelloPreview'; version: #stable; repository: 'github://Metacello/metacello:configuration'; load. "Now load latest version of Metacello" (Smalltalk at: #Metacello) new baseline: 'Metacello'; repository: 'github://Metacello/metacello:master/repository'; get. (Smalltalk at: #Metacello) new baseline: 'Metacello'; repository: 'github://Metacello/metacello:master/repository'; load. But it errors with: Could not resolve: ConfigurationOfMetacelloPreview [ConfigurationOfMetacelloPreview] in c:\smalltalk\squeak\package-cache github://Metacello/metacello:configuration ERROR: 'GoferRepositoryError: can''t find EOCD position. What do I need to do? Ultimately I want to get Seaside but, apparently I need this first. Thank you. Holly.

TextMorph not showing all text...
by Christian Kellermann 18 Sep '18

18 Sep '18

Hi! I have hit another issue I don't understand by browsing the system alone. I have a TextMorhph inside a PasteUpMorph inside a ScrollPane inside a SystemWindow. When I fill it with text exceeding a certain size it gets cut off: Scrolling goes not to the end of the text. When inspecting the TextMorph I see that the content is there fully so the display logic must be somehow responsible for this. Any hints on how I could further debug this? Kind regards, Christian -- May you be peaceful, may you live in safety, may you be free from suffering, and may you live with ease.

How to create a TextMorph with Text containing links
by Christian Kellermann 15 Sep '18

15 Sep '18

Hi List! I want to program a gopher client in squeak and I am a bit stuck on how to do the rendering. I got the hint that I could use a TextMorph since there links are a text attribute. However I am a bit clueless on how this is supposed to fit together. What I did atm was that for gopher menus I have an OrderedCollection of MenuItems. Those in turn have implemented their #asText methods. For links I am returning TextURL objects there. This is all collected in a GopherPage's #asText method where said orderedCollection is #join'ed together. As it turns out though, the TextMorph will render my URL as if the #printOn: message has been sent to it. TextURLs will show up in the TextMorph as 'a TextURL'. My guess is that the #join is responsible for this. How am I supposed to add URLs into Text? Kind regards, Christian -- May you be peaceful, may you live in safety, may you be free from suffering, and may you live with ease.

Question about Etoys Custome Events and Triggering Objects
by Jeremy Landry 09 Sep '18

09 Sep '18

This question pertains to Etoys 5. I'm trying to set up communication between two objects using event triggers, but cannot seem to understand what I'm doing wrong. Here is the project: https://drive.google.com/open?id=1hQ9VqRkQu4VeH75dxV0inwL4HXGMDZFg Here is the description of desired effect: The playfield tells all Enemy objects (just one in this case) to 'bounceAround'. Then following that, tells all BGTile objects to 'beSolid'. If the Enemy object overlaps any BGTile object with it's variable of 'isSolid' set to True, that BGTile object triggers an event the Enemy object responds to. The problem is that the trigger isn't seen by the Enemy object as having come from BGTile but from the entire playfield! I set up a variable within Enemy to figure out why setting Enemy's Bottom to Enemy's Triggering Object's Top would send the Enemy completely off the screen. Is this because the originating script that is ticking is the Playfield's script? If so, how should I set this up to create a situation where sibling objects can find specifically which ones actually collided if the Triggering Object will always be the originating ticking script? Thanks for any help and I hope this makes sense. I left the offending scripts open along with the Enemy viewer flap so that the triggering object variable is seen.

Etoys and BIG CUSTOM FONTS. :)
by Jeremy Landry 07 Sep '18

07 Sep '18

I made this project for Etoys 5 showing a solution to doing custom lettering with mindset of reusing creations a little more efficiently. While the instructions/how-to are in the project itself (along with a demo as always), there's ways to improve it via scripting beyond the tiles however, I did keep it Etoys tile scripting capable only, which means it's rather labor-some to some degree, but still rather useful. I hope anyone using Etoys for presentations checks it out as I think they'd find it useful and if not, well, at least you get a cool futuristic graphical font I made. :) https://drive.google.com/file/d/1XQtFlm4KK3EBYEMqnMLGgNZgfqYdLKZ-/view?usp=…
