Not better, just different. In the general case, shortcuts with ctrl use cmd on Mac (like ctrl-c, ctrl-v, etc), but some navigation shortcuts (like previous / next word) use alt on osx where windows use ctrl. So having both meta and alt-meta bindings as I described, lets you represent both, but, due to the nature of alt, some care/restrictions would need to be applied to alt-meta that are not necessary for meta. -- View this message in context: http://forum.world.st/GT-Spotter-dive-in-shortcut-tp4899612p4901704.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Re: [Pharo-dev] GT-Spotter dive in shortcut

by Tudor Girba

Hi, Command is an actual key on Mac next to Option(which is Alt) and Control. So, Command is a concrete key and mapping it logically to another key on another platform is mixing semantics. I propose to have two distinct layers in the image: 1. the raw layer is about having a distinct selector for each concrete key that is found on the keyboard. Right now, it seems to me that the VM does a bit of interpretation and mapping, and if it does, I think it should just provide a distinct code for each distinct key. 2. the portable layer is about having a couple of selectors (e.g., #meta, #secondaryMeta) that provide consistent mappings to the raw keys. So, in this way, #command/#control/#alt would belong to layer 1. and #meta/#secondaryMeta (we could find a better name) would belong to layer 2. Does this make sense?

This works on windows and linux. Cleaning up the shortcut handling, would make it easy to change this to ctrl+backspace (there is already an issue about this, for windows, but this applies to linux as well: 13882 <https://pharo.fogbugz.com/f/cases/13882/Under-Windows-the-key-to-remove-a-w…> Under Windows the key to remove a word is not SHIFT+Backspace but CTRL + Backspace)

AthensCairoSurface not getting garbage collected

by J.F. Rick

I'm using Athens rendering for my multi-touch applications on Pharo5. As part of that, I create a surface: surface := AthensCairoSurface extent: bounds extent asIntegerPoint. Though the object creating that surface is deleted, the surface sticks around. So, each time I run the app, I get another instance of AthensCairoSurface hanging around. That means all the forms stick around as well. So my image can quickly grow towards the 1GB size. Is there anything I can do about that? Can I manually get the surface to delete itself? Cheers, Jeff
