Where can I find the definition for #copyForRealMemento?

by Richard E. Flower

It appears that this method should live in the object (or superclass) that is to be Magritte rendered.. I can't find it in my Squeak image but it is referenced by #pull as seen below.. Up to now I thought I was using the RealMemento class as specified by #mementoClass but just found that it needs to be defined on the instance side not the class side so my #mementoClass method was not being called until now.. Unfortunately now I get the DNU as indicated above.. MARealMemento>>pull "Utitlity method to copies the model into a cache populating nil values with the defaults specified by the descriptions" | result | result := self model copyForRealMemento. result description do: [ :each | (result readUsing: each) ifNil: [ result update: each default using: each ]. ]. ^ result

Pier Templates

by David Zmick

I am going to distribute different file libraries from my site( http://w337.uni.cc) that contain css for different Pier looks. It seems to me, as I was recently a Pier newbie, one of the things that could scare me away was how hard it was to change the look of Pier, and I think this will help. Could someone tell me how to set up a Monticello HTTP repository with apache so I can host some of theses? -- David Zmick /dz0004455\ http://dz0004455.googlepages.com http://dz0004455.blogspot.com

the idiot's guide to pier

by Sean Allen

I'm feeling like I need one. I've been playing around with Pier for a couple days and well... I don't feel much further along when than when I started. Basic things like... how you change the style, theme, layout whatever you want to call it are simply a mystery to me. Is there a 'these are the must know basics' guide? I went back to sometime last year in the archives, tried googling, read stuff on the wiki and off of Lukas's site but still feel utterly lost. I see there is a PRPierFrame that everything else is inside. Do I remove the children from it, rearrange them? Write my own? That is just one basic thing I'm not grasping.. Any links to getting started basics would be greatly appreciated. in the meantime, back to trying to figure this out. Thanks. Sean

Memento don't work on my component when clic on cancel button

by Dario Trussardi

Hi All, i work with Squeak and Magritte. I have create my personal component "SUAddress" subclass of MAElementComponent. And define the relative MAAddressDescription subclass of MAElementDescription with methods: kind ^ OrderedCollection defaultComponentClasses ^Array with: SUAddress After i define in TestClass with: descriptionAddress based on MAAddressDescription on addressData and descriptionText based on MAStringDescription on textData. Now when call: anTestClass asComponent addValidateForm; addMessage: 'message' ; yourself all work fine. The problem is when in the form i do change on my component and after i clic the cancel button. In this case the addressData result update to the change do in the form, and not to the last correct state. The textData in this case work fine. Where i wrong ? Any pointers would be greatly appreciated! Thanks! Dario

determining "save" or "cancel" status on #rendered Magritte component...

by Richard E. Flower

Lukas et-al, I've got my test Magritte form working from a renderContentOn: block without issue (data is displayed,buttons exist,no complaints, etc).. Anyway, at the bottom of the form (using the code below) are 3 buttons (save,cancel and then my 'done' button).. The thing I'm having a hard time with (which was easy when using #call and #answer) is how to determine what button was pressed (save,cancel).. Ideally, I don't care to have a "done" button but I do need to distinguish between save and cancel.. What's the best approach for this? I copied the onAnswer: block from another old Magritte email thread but its only called when cancel is pressed.. Thx! renderContentOn: html component := (self session user) asComponent addValidatedForm; onAnswer: [ :value | self answer: value ]; yourself. html div id: 'fullwidthContent'; with: [ html div id: #fieldsetEnclosure; with: [ html render: component. html submitButton callback: [self answer: 'foo']; text: 'Done' ] ] -- Rick

What does reduce: get used for?

by Richard E. Flower

I'm not completely following what its purpose is? Below is the code from the Magritte, living in the SequenceableCollection object: reduce: aBlock | result | self isEmpty ifTrue: [ ^ nil ]. result := self first. 2 to: self size do: [ :index | result := aBlock value: result value: (self at: index) ]. ^ result In my case, it is causing problems on VW when it calls aBlock (near the end) and passes in a pair of Characters which are processed by MAComponentRenderer>>classFor: which then tries to do a string append (#,) which gives a DNU since VW's characters (and I think Squeak from what I can tell) do not have concat methods (#,).. Am I missing something? Below is the code that calls reduce: MAComponentRenderer>>classFor: aDescription | classes item | item := (component description = aDescription ifTrue: [ component ] ifFalse: [ self childAt: aDescription ]) ifNotNilDo: [ :comp | comp model ]. classes := aDescription cssClassesForItem: item. (self hasError: aDescription) ifTrue: [ classes add: 'error' ]. ^ classes reduce: [ :a :b | a , ' ' , b ]

[smallwikki/pier] Magma on squeak-web 3.10 image

by David Zmick

I tried to run the installer script for Magma-Pier from http://www.iam.unibe.ch/pipermail/smallwiki/2007-April/002794.html, and it didn't work, not that i am surprised, the script is for a fresh image. What packages to i need to install to this image to get Pier to work with Magma? -- David Zmick /dz0004455\ http://dz0004455.googlepages.com http://dz0004455.blogspot.com

about making magritte more flexible... and founding the case for L17N

by Esteban Lorenzano

Hi, This is a "disgression" of something I thought/implement last week and I want to put into consideration, in order to know if is a valuable contribution or just another stupid idea :) First let mu put some context information: I'm using magritte for some production applications, who has two major requirements: L&F and L17N. For major of my needs, magritte fits quite well, but it still have some restrictions: 1) No L17N in labels and buttons. 2) Buttons are texts and usually clients ask for images, images/texts, etc. There are some other restrictions, but achievable by simply extending magritte system (such as image report columns, etc.) How do I solved this problems? Well, first I simply added a "localized" method on String who asks for a property (language) in session and follow "translated" path to translate the string, and then I modified each method in magritte who outputs a label (they are not many, just 3 or 4). That solves my L17N problem. Now, I want to make my buttons more fashionable... this is harder because of the places where I have to change things... but again, extending MAFormDecoration and MACommandColumn... and aplying that to every component who uses a report... problem solved. But, what if I what my buttons different, or even configurable? This is my approach: instead having buttons and links displayed in columns or forms, I created a Command, and then I whant to add that commands by visiting different renderers, magritte style visitors. So, if I want to change the displaying style, I just add a new renderer... And as an "extra bonus" there I can handle L17N stuff. What do you think? is this good approach?
