Sadly BitBlt and/or Balloon don't support much so we're stuck with GradientFills and rectangles for shapes (where the double-dispatched "puting the behaviour in the fill style" is concerned, unless the low-level shape drawing types are all dispatched)... As for the original question, BoundedGradientFillStyle simply allows for an extent so that, as part of a composite, it can be limited to only part of the drawing area. This makes it possible to make composites that have different corner images (for example) along with gradients for the "stretchy bits" in between... In respect of the isXXX methods, these could be refactored properly such that the morph informs its fillStyle of bounds changes. For simple colours this would be effecitvely a no-op, gardients would adjust their origin etc. Regards, Gary ----- Original Message ----- From: "Igor Stasenko" <siguctua(a)gmail.com> To: <Pharo-project(a)lists.gforge.inria.fr> Sent: Saturday, March 14, 2009 9:13 AM Subject: Re: [Pharo-project] [ANN] 10252 > 2009/3/14 Igor Stasenko <siguctua(a)gmail.com>: >> 2009/3/14 StÃ©phane Ducasse <stephane.ducasse(a)inria.fr>: >>> I will let gary reply and rollback if necessary. or even better >>> integrate next fixes :) >>> I thought it was ready for integration. >>> >> I didn't said its not ready.. >> I just wanted to point out, that it is half-done, in the way how i see >> it should be done. >> It works, of course, but not so elegant as it should be :) >> >>> stef >>> On Mar 14, 2009, at 2:15 AM, Igor Stasenko wrote: >>> >>>> 2009/3/13 StÃ©phane Ducasse <stephane.ducasse(a)inria.fr>: >>>>> Added BoundedGradientFillStyle. >>>> >>>> can to elaborate , what is it? :) >>>> >>>> We duscussed the fill styles with Gary a while ago, and the result of >>>> a discussion is to make fill styles to know what they need to do to >>>> fill the given shape i.e. fill style could be seen as a function: >>>> f(shape, canvas) >>>> > > going further with that, all drawings (not only fills) on canvas could > be represented by such function > f(shape, canvas) > but it would require a deep refactorings in bitblt/morphic engine to > do such unification. > > With such approach, it would be easy to introduce a new fill styles, > such as bevel/emboss, blur , etc. > While old fillstyles implementation is quite limited, because > fillstyle used as a dumb state holder and drawing engine performs > different tests (isXXXX) to do the right thing. > >>>> and, to use a fill style, in general form, you simply should use: >>>> myfillStyle fill: someShape on: canvas. >>>> >>>> This concept were introduced into Polymorph, and as first proof of it, >>>> Gary implemented a composite fill styles. >>>> But it's far from complete.

Re: [Pharo-project] Setting package test

by Adrian Lienhard

Hi Alain, Nice to see you making progress! I've taken a quick look at the GUI and the code. Here some feedback: - When I change a value, why do I get a red border (for me this indicates that the change is invalid)? - Set to default doesn't do anything - Dropdown lists are displayed at the wrong position on the screen (I'm using the default theme, Watery2) - At first I didn't recognize the slider control (glyph contrast setting) - Instead of using the old change notification mechanism, you could use Announcements - The method #domainValues: looks a bit fishy with the isKindOf: checks - The method #maxNameWidthForFont: can be simplified by using #detectMax: A search/filter would certainly be useful.

Re: [Pharo-project] Setting package test

sound good. I really like the idiom to have a class var on a package this is really a nice way to let the dev think that a preference is not a system global variable (aka old preference) but a local to the package references. This way we will be able to slowly arrive to have preference as a top layer :) Stef On Mar 14, 2009, at 1:38 AM, Alain Plantec wrote: > Hi all, > Preference is now renamed as Setting. > Please, can you can load these two packages and play with the > settings. > 'SettingTree open' open the browser. > Examples of setting are located in the Setting-SandBox category. > You can use <pharo> or <setting> as pragma. > the pragma list the browser is able to recognize is now a parameter. > (see SettingCollector class side). > as an example, It will be possible for an application to use its own > pragma symbol.

[Pharo-project] Setting package test

by Alain Plantec

Hi all, Preference is now renamed as Setting. Please, can you can load these two packages and play with the settings. 'SettingTree open' open the browser. Examples of setting are located in the Setting-SandBox category. You can use <pharo> or <setting> as pragma. the pragma list the browser is able to recognize is now a parameter. (see SettingCollector class side). as an example, It will be possible for an application to use its own pragma symbol. Thus, the browser will be able to show application specific settings. I will add 'saving', 'saving as', choose, open, and 'filtering' features (by package or by setting name as available in current preference browser). If you have more ideas or needs, please let me know. Cheers alain
