Is there a tandard way to attach context menus
by Herbert König 04 Nov '11

04 Nov '11

Hello all, is there a standard way to attach a context menu to a morph? It's fairly easy to do by checking for yellowButtonPressed and manually firing up a MenuMorph. But it is sufficient to implement #addCustomMenuItems:hand: to get an enhanced Halo menu while #addYellowButtonMenuItemsTo:event: and #hasYellowButtonMenu don't help. So is there a predefined way without everybody doing his own? Thanks, Herbert mailto:herbertkoenig@gmx.net

Omnibrowser help
by Rob Rothwell 14 Aug '11

14 Aug '11

Are there some tips/documentation somewhere on getting the most out of the OmniBrowser? The MulitpleSelection browser looks interesting (sort of like the tabbed browser in VisualWorks), but I don't quite understand its behaviour and what method it decides to show in which pane when you move around or save changes. On the same topic, can anyone point me toward how I could add a new item to the class context menu in the OmniBrowser? I want to add a new template selection menu item (like "new class template" and "new trait template") because I have created a method that creates TWO classes at the same time for an Aida application (A domain model class AND its associated WebApp class). Thanks, Rob Rothwell

Immutable environments in blocks?
by Jeff G 26 May '11

26 May '11

Hi everyone, My question is about the semantics of block closures in squeak. I played around with scheme a bit in order to do some comparisons and one big question I have is how to alter the outer environment from a closure. An example of closure semantics given by Ian Piumarta on squeak-dev in 1999 is as follows. mkCounter := [:init ¦ [init := init + 1]]. b1 := mkCounter value: 42. b1 value. 43 b1 value. 44 I never get 44 returned from the current squeak trunk. I only ever get 43, which suggests to me that the assignment to init in the inner block is not actually ever over writing the init value in the outer environment. How would I go about altering the outer environment from inside a block if I desired to do so? Thanks for all your help, Jeff G.

Really silly newbie question..
by Junkie Junk 24 May '11

24 May '11

Hello, I have just installed and started playing with squeak 4.1 all-in-one edition. I have just found an annoyance, which I couldn't get rid of. There is a white text area at the bottom of the squeak main window. It seems to be up all the time and it is on top of all other components, i.e. menus, other windows within squeak goes under it. How could I get rid of this text area? I drew the border of that text area with a red rectangle as you can find in attachments. Thanks in advance.

All-in-one download of Squeak 4.2
by Joaquin Sitte 15 May '11

15 May '11

I have just installed Squeak 4.2 in Windows XP using the only available download option (All-in-One) from www.squeak.org It does not decompress as described under the link "Need installation help" which is a nuisance, but more importantly there is no apparent way to open Squeak with any other image than the one downloaded (4.2-10966). There is no menu option and all the ways described under the Windows installation page of the documentation do not work. How can I select the image I want to work with in 4.2?

Bert Freudenberg's Squeakfest 2010 presentation available
by Steve Thomas 14 May '11

14 May '11

If you want to see the power of Etoys (and squeak) and a great talk by Bert check this video of his Squeakfest 2010 presentation<http://www.youtube.com/watch?v=WUxMP46PM-I> . Its amazing how simple it is (once you know how ;) to create your own "tiles" and interface. FYI, one of the things Bert does is create a "Player" variable in Etoys. I tried this in Squeak 4.2 and after creating the variable for an object in the viewer I got an exception when I tried to "change value type" - "This message is not appropriate for this type of object".

Sprite animation in Morphic?
by Casey Ransberger 11 May '11

11 May '11

Hey all, I have a big pile of sprites (frames of bitmapped character animation with bit-masks) that I'd like to animate. I've done this before in the raw with C, but never with Morphic. I'm afraid I'm liable to reinvent the wheel unless I find a lead on what the right way to do this is in Morphic. Can anyone point me in the right direction? -- Casey Ransberger

Getting HPDF running
by Leo 08 May '11

08 May '11

Hi, I'm trying to build some PDF-Files from Squeak and stumbled over the HPDF- Framework, which seems to suit my purpose pretty well. So I installed the FFI and HPDF packages and tried the tests. Since the ones for HPDF fail, I assume that I have to use the libHaru Libraries and to combine them somehow with this FFI-thing... ...but actually I have no idea how to do that! :( Could anybody give me some advice? Probably that's a dumb question, but I would enjoy Your answer nontheless. ;) Best regards, Leo
