[Pharo-project] UIManager>>request: does not send ProvideAnswerNotification anymore
by Damien Cassou March 19, 2009

March 19, 2009

Hi, it seems that calling #request: does not trigger a ProvideAnswerNotification. This notification is used by #valueSuppressingMessages:supplyingAnswers: to automatically fill text requests. Can somebody check that? [UIManager default request: 'Please choose a username for\the application ' withCRs , 'config' printString] valueSuppressingMessages: Array new supplyingAnswers: (Array with: (Array with: '.*username.*' with: 'admin')) -- Damien Cassou http://damiencassou.seasidehosting.st

[Pharo-project] Composing UI layout question
by Igor Stasenko March 19, 2009

March 19, 2009

Hi folks, suppose you having a visual UI editing tool, where you can place morphs/controls and define their position(s). I have a model in mind, where coordinates can be defined by formal description, i.e. morph left: morph parent left + some offset morph width: morph parent width / 2 etc. but i wonder, in what way such relations can be represented by UI editor/design tool. I want that user could easily specify following: suppose i placing a button in form, and say that its corner (bottom/right) should be aligned to its parent corner, with some negative offset (-5 @ -5). And button width/height should be calculated by taking a button label text width & height. So, user by specifying two ordinates - corner and width & height, is fully describing a button visual layout. The problem is that button's label is submorph, and i not sure how to formally encode such relation i.e. parent width & height (or any other parent coordinate) depends on its submorph's fixed width/height. -- Best regards, Igor Stasenko AKA sig.

Hi Igor, I like the fraction/offset model from SmalltalkMT. I once ported it to Squeak. This gives you full control on absolute and relative positioning within the bounds of the parent and controls resizing behavior. Only 4 parameters for anything you need ... Example: self addMorph: startButton to: pane offset: #(0 0 101 20) fractions: #(0 0 0 0). means the button starts top left at x1=0, y1=0 with the bottom right corner at x2=101 and y2=20. There is no fraction given - so we have absolute positioning. If you give a fraction you tell the system that for instance a subpane should always start at 30% from the side of a parents box. -> relative positions with resizing. If you additionally give an offset you can define that there is an additional absolute margin after the 30%. With a negative offset you can absolute position the control/submorph on the other side of the 30% virtual line. With fractions: #(0 0 1 1 ) which means 100% the control will fill the parent and will fully resize with it. Smalltalk MT used 1000 for 100% of the parents area, but thats only a definition. Have a look at the project "Sandcastle" on Squeaksource, especially Sandcastle-tbn.9.mcz. SCApplicationWindow (a subclass of SystemWindow here) provides a few methods to support this dynamic layout and its subclass SCWelcomeWindow shows how you can use it. Hope this helps Bye T. -- Aufgepasst: Sind Ihre Daten beim Online-Banking auch optimal geschÃ¼tzt? Jetzt absichern: https://homebanking.gmx.net/?mc=mail@footer.hb

http://goran.krampe.se/blog/Squeak/Tirade.rdoc In my revived work on Deltastreams in Squeak I ended up facing the choice of native file format for Deltas. Matthew has made an advanced format calledInterleavedChangeset which manages to squeeze a binary representation of a Delta into a Changeset file (which is in Smalltalk chunk format). An impressive feat, and it has the advantage of being backwards compatible in the sense that a Delta in this format can be filed in as a plain old Changeset into an old Squeak image. .....

[Pharo-project] Condense Changes error
by John Toohey March 19, 2009

March 19, 2009

When I run condenseChange on my Phao image (10255), it stops after about 95% with a 'syntax error' message. Closing the message does nothing and the process seems stopped. If I delete the changes file, the image is okay, but the parameter names of all my methods has been changes to t1, eg, renderContentOn: html becomes renderContentOn: t1 etc. I can't make any more changes, and need to know how to repair the changes file, or just get rid of it without it changes my source code. -- -JT

this is strange I tried to integrate http://code.google.com/p/pharo/issues/detail?id=655&colspec=ID%20Type%20Sta… http://code.google.com/p/pharo/issues/detail?id=658&colspec=ID%20Type%20Sta… http://code.google.com/p/pharo/issues/detail?id=664&q=label:unimplementedCa… then already two times all the packages got dirty. I thought I made a mistake using the 40 VM. But this is not the case. So I'm retrying with a 10248 and updating. Stef
