Re: [Pharo-project] Dynamic GUI possible?

by Gary Chambers

You might investigate using a Groupbox with a getContentSelector. That way your model can replace the group content depending on your conditions. A simple example is attached. File in and doit on ExampleModel new open; inspect In the inspector bottom pane doit for: self aVariable: #one or self aVariable: #two or self aVariable: #blank (or anything else for that matter) Your model should implement a method that answers the content (morph) for the group depending on your conditions. Doing "self changed: <selector>" (<selector> being the name of that method) in the model object will cause the group to change its contents appropriately. Hope that helps! Any questions, do ask, though not around at weekends! Regards, Gary ----- Original Message ----- From: J. P. L.

I've never tried that, however using Tools > Finder > Selectors to search for 'visible', I see Morph>>toggleVisible and friends. Since #newButtonFor... eventually returns PluggableButtonMorph, perhaps you try.... ---- newRow: {button1 := (builder newButtonFor: self action: #listaPrestamos label: 'Prestamos' help: 'Listar Prestamos'). ---- ...and then later try button1 toggleVisible. No guarantees this will work, but at least something to chew on. cheers -ben J. P. L.

[Pharo-project] Fwd: How can the main window title in Squeak and Pharo be set?

by Torsten Bergmann

>From the history of Squeak and Pharo you can: 1. Squeak.exe (VM for Windows) was always able to set this using the Setting "WindowTitle" in Pharo.ini - see http://squeakvm.org/win32/settings.html This was implemented by Andreas Raab (maintainer of SqueakVM) 2. Later there was the idea in Squeak for a project called "Areithfa Ffenestri" that should add more support code to Squeak to allow access to the native window or open new ones: http://wiki.squeak.org/squeak/3862 This is a VM plugin that is not in all VM's and even after years AFAIK not fully implemented on all platforms. If it is available then you can do what Bert Freudenberg suggested here: http://lists.squeakfoundation.org/pipermail/squeak-dev/2013-January/167766.… Dont know if the Pharo VM maintainers added this plugin too. You have to ask Igor or Esteban. 3. While Squeak tries to stay platform independent and encapsulate platform dependent logic mostly into VM plugins to unify the access there is some other idea in Pharo now: With the growing need to easily access platform logic of the underlying OS or access external libraries written in other languages there is a new FFI plugin which is (since Pharo 2.0) will be included in the standard distribution. This new Foreign Function Interface (FFI) is called NativeBoost and will move more logic into Smalltalk itself. So you dont have to write/compile a plugin. You just need a VM with NativeBoost support (NBCog.exe on Windows) Using native Boost (when in Pharo 2.0) you can (already!) write: NBWin32Window getFocus setWindowText: 'Hello using Native Boost' to change the window title. Internally I just call the Windows Win32-API function "SetWindowTextA" using the window handle. If someone from other platforms implements an NBUnixWindow, NBMacWindow, NBRiscOSWindow, ... we can also implement a common interface class (NBPharoWindow for example). Hope this helps a little bit Bye T.
