[Pharo-project] Class Browser

by Torsten Bergmann

Hi Anthony, I guess there is no documentation (refcard or the like) since the icon may change and are specific to the OB Browser. You can even have your own. Since Smalltalk is very, very dynamic it is often the case that it is much easier to look at the system itself than to ask for up to date documentation. For the icons you should search for the implementors of the method #browserIcon. You can do this using "Tools" -> "MethodFinder". In my image I have - Collection and subclasses (three objects) - Exception and subclasses (a flash) - Magnitude and subclasses (a sum sign) - Morph and subclasses (a morph) - OBAnnouncement and subclasses (a bubble) - String and subclasses (a paragraph sign) - TestCase and subclasses (dynamic icon, depend on the sucess of running the test green, yellow or red) The implementation in TraitDescription and ClassDescription who return a blank icon just assure that there is no icon displayed for traits and classes by default. If you want to know about the inner workings of this mechanism: The #browserIcon returns a symbol that is a method selector on class OBMorphicIcon returning the icon using a form instance. Just have a look at class OBMorphicIcon. To implement an own icon on your class: - create an icon (typical 12x12) in your paint program and save it as PNG or GIF - use the following snippet to generate code from the image: | image stream | image := ColorForm fromFileNamed: '/path/to/icon.gif'. stream := WriteStream with: String new. image storeOn: stream. stream contents inspect. - create an "icon" method by pasting this code in a custom extension method on OBMorphicIcon (put it in a method category with * and the name of your Monticello package). For instance the "OB-SUnitIntegration" package does just this by providing the test case icons in a method category "*ob-sunitintegration" on class OBMorphicIcon. If this is still magic for you, you should learn about Monticello source code packaging using "pharobyexample.org" - implement #browserIcon on you custom class to return the selector of your "icon method" If in doubt, just ask.

The exception are tests which have a bullet with the SUnit result color of the last run, or gray if there is no data is available. Methods have a green arrow pointing upwards if there is a super implementation, and a green arrow pointing downwards if there are sub implementations. You can click on these icons to see the hierarchy and navigate to the actual implementations of these methods. If the method is flagged a blue flag is displayed instead. If there is a breakpoint a red flag is displayed instead. Finally, if this is a test method, then a bullet with the SUnit result color is displayed. Depending on what you have loaded in your image you might see different icons. Packages can override #browserIcon and #browserIcon:selector: to add custom icons for classes and methods. Seaside for example does that. Lukas -- Lukas Renggli http://www.lukas-renggli.ch

Re: [Pharo-project] Class Browser

by Anthony G. Anton III

Correction (sorry for the confusion)... My apologies if I have overlooked obvious sources which provide the answer to the question... Where is there documentation to be found describing the meaning of list entry icons (on left side of lists) in the Class Browser? I am poking around in the "Pharo1.0-10508-rc2dev10.01.2" image and am not coming up with answers. I've been able to guess at the meaning of some but others escape me. -- ---------------------------------------------------------------------- Anthony Anton 3800 243rd Place SE Phone: 425-313-1024 Issaquah, WA 98029 Cell: 425-444-3084 Concept Systems agantoniii(a)earthlink.net FAX: 425-313-1024

Connect to squeaksource.com with an ordinary web browse. Select "register member" and register yourself with a new account. You will have your own user ID and password that you can use for making the MCHttpRepository connections. Yuu can use the ordinary web browser for setting up your account and project, and once that is done you can use Monticello in Pharo/Squeak to save versions of your project. Dave

Not really, you can drag and drop any changes file onto any image and it'll popup the same changes editor that recover lost changes does.

The default one MCHttpRepository location: 'http://www.squeaksource.com/' user: 'squeak' password: 'squeak' doesn't seem to work. I don't mind hosting my own, but I am definitely a noob at squeak source control.
