I guess the question is: how should normal client or user code that used to do something like Smalltalk at: #Point be written ? Should we just do Smalltalk globals or self environment. In the last case, there is the question whether an instance method would be needed. Sven

[Pharo-project] Latest Polymorph improvements

by Gary Chambers

Time for another accumulated bunch of things ;-) Attached change set Summary: AlphaImageMorph can now answer effective image bounds for a rectangle in display bounds allows use of on-screen crop tools etc. to specify area in image terms with respect to layout/scaling etc. CheckboxButtonMorph always honour explicit click/move handlers CheckboxMorph extra property to facilitate taking keyboard focus on click (can be used in conjunction with text editors to accept on (keyboard) focus change) shrink horizontally by default update enablement on label change DropListMorph support wrapSelector on underlying list FileDialogWindow update file list when directories added/removed ListModel extra change/update aspect for list order (allows using a list model to reorder a list via drag/drop) MorphicUIManager openModel uses detected modal morph rather than blocking World by default PSMCPatchOperationWrapper use summary of definition (avoid MNU on #selector for reorganisation operations) PluggableButtonMorph extra property to facilitate taking keyboard focus on click PluggableSliderMorph avoid possible ZeroDivide on bad parameters PluggableTextFieldMorph minor performance, reuse already calculated string ToggleMenuItemMorph centre text when vertical extent more than minimum UITheme Use a PanelMorph for label groups (allows disablement of group... ideally would want a major rework for parent enablement dependency though) Regards, Gary

As i said before, Text (class) model is a very limited and don't scales for big texts (multiple pages etc). Because if you imagine you editing 300kb text (book), any operation like insertion of a single character will require copying 300 thousands of characters into a new space holder. IMO Text is good for a couple lines of text (like smalltalk code). But for something bigger, like Word it should be completely different and require completely different approach and modelling. >> >> (i would just throw it away ;) >> > Yes. > > Â Â Â Â Marcus > > -- > Marcus Denker -- http://marcusdenker.de > -- Best regards, Igor Stasenko.

Re: [Pharo-project] Accessing the OS Environment Variables

by HernÃ¡n Morales Durand

Some time ago I've added some extensions to FileSystem to resolve path's using OS variables, I don't know if they were integrated. With ProcessWrapper you may use in Windows: ProcessWrapper new useStdout; startWithShellCommand: 'echo %programfiles%'; upToEnd then you need to trim the output.

It is likely that it has never been used outside of this Demo. The idea was that morphs could be the building blocks of a text layout system like we see in Pages or Word (or better example FrameMaker). So if you want to have two paragraphs on one page, put two textmorphs and let the text flow beteen them. No model, the morphs are the model and the view at the same time.

That's for the flowing of text between several morphs (like columns, or what prepress applications do) I believe?

I certainly not such kind of person, who would do such job: picking random issue and sending an individual mail to some random person taken from 'bugfixers list' :) I think you can do such job pretty easily by youself: open an issue tracker , close your eyes , randomly move the mouse and then click.

Actually it would be nice to have a bot which automatically closing unattended issues after month of inactivity, and mark them as 'closed (unresolved due to inactivity)'. Because if there's nobody who wants to fix it, why we should keep it listed? -- Best regards, Igor Stasenko.
