Re: [Pharo-users] ProfStef, Lesson 25 - Unknown selector

by Joachim Tuchel

Hi, I am not sure whether Pharo implements or once implemented a special method like executeMethod: but in Smalltalk the selector for sending a message to an object is #perform: so you should probably try to replace #executeMethod with #perform: . But I am sure somebody more familiar with ProfStef and Pharo will comment on your issue more specifically.

Hi all, Reading ProfStef at lesson 25 (Reflections), when I try to run the last statement <code>ProfStef default executeMethod: (ProfStef lookupSelector:#next).</code>, the error pops up saying <error>Unknown selector executeMethod:</error>.

Shortcut to "Browse Class"

by Bahman Movaqar

Hi all, As an absolute beginner, when using a workspace, most of the times I don't know the type of the value returned by a piece of code or its methods. So I have to select the value, right-click on it, from the menu (BTW is there a name for this menu?), select "Explore" and then select "Browse Class" or "Browse Full". Is there a shortcut to this functionality? TIA, -- Bahman Movaqar (http://BahmanM.com) ERP Evaluation, Implementation & Deployment Consultant PGP Key ID: 0x6AB5BD68 (keyserver2.pgp.com)

Writing a GUI - Where to start?

by Bahman Movaqar

Hi all, I need to build a typical GUI application (menus, buttons, modal dialogs, ...). I'd appreciate if you could point me to where should I start and what are the choices for a UI framework in Pharo?

ImageMorph scaling

by Sean P. DeNigris

How would I get an ImageMorph to automatically resize inside a Spec UI? I put it in a PanelMorph with various layout attempts, the latest being: image := PanelMorph new changeTableLayout; hResizing: #spaceFill; vResizing: #spaceFill; yourself. Where image above is an accessor referenced in #spec Then I added: imageMorph := ImageMorph new image: form; hResizing: #spaceFill; vResizing: #spaceFill; yourself. image addMorph: imageMorph. The form shows up as the full original size, but strangely if I bring up the halos on the ImageMorph and just wiggle the scaling halo, it resizes to fit the PanelMorph. But then if I resize the window again, the image doesn't rescale. Thanks. ----- Cheers, Sean -- View this message in context: http://forum.world.st/ImageMorph-scaling-tp4719248.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Multicolumn text view with spec

by Benjamin

An old version of spec is usable in 2.0 The 3.0 version is _far_ better. You may want to use MultiColumnListModel (itâs the widget used in the senders/implementors UI) Otherwise, you can indeed use the scroll sync example to sync to lists together.

I'd appreciate any suggestions for those libraries. HTTP is, of course built in. For JSON parsing, you can use NeoJSON. Open the Configuration Browser and install is.
