[Code Request] ProgressBar morph widget
by Piero Campanelli 27 Feb '00

27 Feb '00

Hi. I am building a GUI for SUnit framework port. I'd like to add a progress bar widget(which tells how many tests have been done). Any of you is developing (or has developed) this widget ? Tnx

Hi, ftp://st.cs.uiuc.edu//Smalltalk/Squeak/2.7/files/Squeak2.8a-beo.zip has been updated with these changes. cheers bruce Dan Ingalls <Dan.Ingalls(a)disney.com> wrote: > Folks - > > Herewith a bunch of new updates for test pilots. > > A couple of notes: > Most simple Fabrik examples should now work again. > > We are about to release Andreas's new BitBlt, and these changes include a lot of compatibility work. There is a fair chance that something will not work exactly right (esp in MVC) after these changes, but also some nice things (like translucency in 8 bits) now DO work.

The primary intent is to provide a stronger fence between Morphic and BitBlt (since BitBlt is subject to change very soon). Everyone using lots of drawing methods from Canvas - repeat after me: > 'I will not use combination rules with a Canvas' > 'I WILL use a Color where I mean a Color' > Clients that require effects that are currently not part of the Canvas interface should setup their own BitBlt operations, fetching and restoring the portions of the destination form explicitly (see CornerRounder for an example). For getting the contents of the Canvas the methods #contentsOfArea: and #contentsOfArea:into: have been provided. > For stating the intent of displaying an image more clearly, the following methods have been added: > * drawImage:at:[sourceRect:] > Plainly draw the image (e.g., what used to be represented as Form>>over). > * paintImage:at:[sourceRect:] > Draw an image that has a certain source key to be treated as transparent (e.g., what used to be represented as Form>>paint) > * translucentImage:at:[sourceRect:] > Draw an image that might contain transparency values. This is an explicit hint for the canvas to choose a representation which is best suited for the target device (e.g., in a FormCanvas this may result in different combination rules depending on the source and target depth). > The public use of the following methods is highly disapproved: > * image:at: > [replaced by #paintImage:at:] > * imageWithOpaqueWhite:at: > [replaced by #drawImage:at:] > * image:at:rule: > [Obsolete] > * image:at:sourceRect:rule: > [Considered to be PRIVATE] > The methods are still kept for compatibility but will definitely go away at some time. > Additional notes: > * You will get errors when attempting to pass a bit pattern as a color.

From the open menu select filelist, choose your file, and then one of the menu options for that file is "File into a new changeset" cheers bruce

Any of you is > developing (or has developed) this widget ? Hi Piero, String has a method, #displayProgressAt:from:to:during:, that you might find useful. It might be enough to suit you and if it isn't, it may serve as a starting point for your new widget. http://www.windwardsolutions.com/People/Hirschfeld/Squeak/Squeak.html has a Squeak implementation of the SUnit framework. Don't mean to stop you from building your GUI, but do want to be sure you know about what exists. HTH, Steve

Comanche mailing list
by Aron Brener 27 Feb '00

27 Feb '00

I remember seeing somewhere something about a Comanche mailing list, but now I can't find any references to it. Can somebody tell me how to subscribe? Since there's probably a lot of people on both lists, let me ask my question here: I have to do a project that involves serving hdml pages (for browser enabled mobile phones.) I created a new module that for the moment just tries to serve a simple page (just for testing) My problem is that, for the life of me, I can't find a way to start the server so that it'll use my module!! Is there anything else I should know before creating my own modules? Let me say that the documentation on Comanche is very sparse and hard to find. In the image, the comment on ComancheServer says it uses HttpConnectionQueue, but that class doesn't exist any more. (just an example). Thank you in advance, I'm looking forward to implement this on squeak, once I get over the hump.
