Writing [[[ in a class comment

by Alexandre Bergel

Hi! I am trying to follow Peterâs coding convention and writing some pillar code in a class comment. However, currently, it is a bit cumbersome. If I type three times the key â[â and press enter I have: [ [ [ ] ] ] Is there a way to have [[[ |<â cursor here ? ]]] Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Re: [Pharo-users] Where do selected morphs get their emphasizing frame from

by Nicolai Hess

The SelectionMorph itself uses the default border width. You can change that by adding for example borderWidth := 4 in the initialization method. the thin border around the selected elements is created by the a 4 times shifted drawing (in drawOn:) (0@0) fourNeighbors do: [:d | form1 displayOn: form2 at: d rule: Form under]. 2015-09-03 22:09 GMT+02:00 christofbuerger via Pharo-users < pharo-users(a)lists.pharo.org>: > > > ---------- Weitergeleitete Nachricht ---------- > From: christofbuerger <christof.buerger(a)googlemail.com> > To: pharo-users(a)lists.pharo.org > Cc: > Date: Thu, 3 Sep 2015 12:55:20 -0700 (PDT) > Subject: Where do selected morphs get their emphasizing frame from > Hello, > tried honestly the whole day to figure out > how morphs in world get their thicker frame from, when they are selected by > a SelectionMorph. > > I wanted to copy/inherit that behaviour and make the frame for such > selected > items thicker than it is done by standard. > > Can anyone please give me a hint?! > > Thank you very much and > Best Regards > Christof > > > > -- > View this message in context: > http://forum.world.st/Where-do-selected-morphs-get-their-emphasizing-frame-… > Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com. > > >

Where do selected morphs get their emphasizing frame from

by christofbuerger

Hello, tried honestly the whole day to figure out how morphs in world get their thicker frame from, when they are selected by a SelectionMorph. I wanted to copy/inherit that behaviour and make the frame for such selected items thicker than it is done by standard. Can anyone please give me a hint?! Thank you very much and Best Regards Christof -- View this message in context: http://forum.world.st/Where-do-selected-morphs-get-their-emphasizing-frame-… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
