CurvierCurves-wiz
by Peace Jerome 09 Jan '05

09 Jan '05

Hi Ned, This is a followup on our pre holiday correspondence. I finished up my next iteration of CurvierCurves-wiz. It has the changes you requested. Subclasses of Polygon get to be curvier unless they specifically ask not to. The new play with me project was generated in 3.7g2. I also loaded it into 3.9a a made sure it worked there. The bug you challenged me to find a fix for it now #0000807 on mantis. (bug fix was adding an 'asColor' to the appropriate place.) I expect the bug fix to be included way before the guides are convinced to add Curvier so it is not included in the Curvier release. I've published the play with me project on sm. And at Bob's superSwiki (http://209.143.91.36/super/649). The superSwiki has the cs as a standalone download as well. And they are attached here. This is my last work on this until its added to squeak. I'll fix any bugs I've introduced that are pointed out to me of course. But the quality of my time changes dramaticly as I go back to my day job monday. So again any help you can give me getting this into the squeak stream is appreciated. Thanks in advance. Yours in service, -- Jerome Peace __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

How to update the appearance of a morph in mid-method?
by Jim Rosenberg 08 Jan '05

08 Jan '05

I have a morph that I want to have "flash" its border color in blue for a couple of seconds and then restore itself to its prior state. I know how to change the border color. I know how to achieve a delay. Everything works if I "do something" to interrupt the method at the point of the color change. But if I let it run, the display seems to be caching the state of the display in such a way that I never see the color change. After the color change I'm trying sending the morph layoutChanged, sending its owner layoutChanged, even going so far as to try Project current world restoreDisplay -- nothing works. Sigh. There has to be a simple way to do this. How do you tell a morph to show itself "right now" in its current condition -- in mid-method? -Thanks, Jim --- Jim Rosenberg http://www.well.com/user/jer/ WELL: jer Internet: jr(a)amanue.com

[ENH] FlapTab performance improvement
by Michael Latta 07 Jan '05

07 Jan '05

When working with some performance tests I noticed that FlapTab was consuming too much time repositioning itself when morphs in the world view resized. The attached change list cuts the time for FlapTab>>ownerChanged by about 33%. With 9 tabs on my image it amounted to a 3% overall improvement. The changes involve testing for position changes before making them so it does not reposition to the same location, and using symbols rather than strings, and == rather than collection>>includes:.

[BUG][FIX] Global Flaps Fix
by Hernan Tylim 07 Jan '05

07 Jan '05

Tried on the latest 3.8 gamma and 3.9 alpha. Here is my fix for dealing with the global flaps disappearance. BTW, in 3.8 the font used for the thumbnail labels doesn't render well in small font sizes. This fix is also registered on Mantis.

"Change Set: GlobalFlapsFix-hpt Date: 28 December 2004 Author: Hernan Tylim This is a .cs with only a postscript that will reinstate the global flaps on Squeak 3.8 (and 3.9). I must say that I don't know if how I am doing it is the right way to do it, but I figured that if after all this months nobody else tried to fix this problem then I should make an attempt to it.

About halos
by stéphane ducasse 07 Jan '05

07 Jan '05

hi I have been creating my own halos and I found quite strange that a lot of the code for halospec and haloMorph is located in Preferences and not on the class side of HaloMorph or HaloSpec. I could of course change that but are people concerned by that or prefer to keep a clunky system? Stef

Input requested on approach to better graphics model
by Michael Latta 07 Jan '05

07 Jan '05

I have been playing with Balloon for several days and encountered several issues. I would like input on how to proceed. 1) The 3.7 image I am working from does not support transformed text. If you try using a TransformMorph that encloses text it does not draw. 2) The TTCFont only deals with integral pixel glyphs. While this makes sense since it caches forms for each glyph, it means that smooth scaling of text is not possible. I would like to see a system that has fractional text metrics. It looks like this can be done with a different font class using the same TT descriptors as TTCFont. I presume I should work with my own font class as there is likely to be a performance issue relative to the cached fonts currently in use, at least for a while. Handling of the scaling of text requires changes to the canvas class. Should I create a subclass of BalloonCanvas? This seems the safest approach, but means that this feature will not be available in places where a BalloonCanvas is currently used. Since no one has missed this feature so far, I guess this is not an issue for anyone. It is not clear if the plug-in can handle glyphs that start at fractional positions, I am hoping this is not an issue, only time will tell. Let me know what you think. If I do all my work in subclasses then of course I can package it more easily. But, then things get bigger when the package is loaded. Michael
