Re: [Pharo-dev] Protrammatic selection in Glamour

by Tudor Girba

Hi Martin, GLMBasicExamples>>treeWithInitialSelection provides an example of how to set an initial selection programatically. Does this help?

Re: [Pharo-dev] compiling code on background / in parallel

by stepharo

If you code something else in parallel you may have problem with the source sanity. I do not think that this element is thread safe and it would be I think that it would block one of the possible several threads that would be wanting to get compiled.

Re: [Pharo-dev] Rearranging Pharo Tabs

by CodeDmitry

Ooh window groups really help! and I can rearrange the tabs by putting them in a tab and out. Would be nice if there was a transparency hint for when you are about to drop it in or not, it's kinda non obvious. By the way, really inspiring speaking there, I am really shy about making tutorial videos since I have a russian accent, and tend to zone out while speaking, but your video is clear and at the same time not accent-free. I should practice making tutorial videos. -- View this message in context: http://forum.world.st/Rearranging-Pharo-Tabs-tp4917802p4917806.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Rearranging Pharo Tabs

by CodeDmitry

I am often put into situation where I have many Pharo windows open, but I want to rearrange them. Is there a way to rearrange Pharo tabs(the ones at the bottom left of the screen)? I imagine it wouldn't be hard to add a new menu entry to the right click menus of them to make the tab swap with one on the left or one on the right. -- View this message in context: http://forum.world.st/Rearranging-Pharo-Tabs-tp4917802.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
