MAPictureDescription missing from Magritte???
 
|
After searching about I've come to the conclusion that Magritte is missing MAPictureDescription + MAPictureComponent classes. I would like to have a passport ilk pictures appear in Magritte generated reports and editors for users of a system by defining a #descriptionPicture class-side method for a system-user class. Not that easy!
I assume I'll need to add these classes (MAPictureDescription + MAPictureComponent) to Magritte? ----John _______________________________________________ seaside mailing list [hidden email] http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside |

Hi John,
MAFileDescription used to display the uploaded image in earlier versions. I changed that to simply put a link for various reasons. There are many different ways to display a picture, sometimes applications need to add special tooltips, make them clickable or resize and convert them to a special format. > I assume I'll need to add these classes (MAPictureDescription + > MAPictureComponent) to Magritte? ----John That would be a possibility, if you need some sophisticated meta capabilities on pictures. For me I mostly went with the MAFileDescription: descriptionPicture ^ MAFileDescription new accessor: #picture; addCondition: [ :file | file isImage ]; componentClass: MAPictureComponent; yourself The condition ensures that only images can be uploaded. The component class changes the default view to a custom subclass of MAFileComponent that automatically resizes and displays the picture. If you want to contribute an MAPictureComponent I am sure some people would be interested to use such a plugin. However I doubt that it is possible to write it in a platform independent way, so that it could be part of Magritte-Seaside. Btw, there is a special mailing-list for Magritte, see <http://www.lukas-renggli.ch/smalltalk/magritte>.

Lukas, not quite certain what you meant by: "However, I doubt that it
is possible to write it in a platform independent way ..."? The platform is the browser; so are you saying it would be browser specific? In what way? (The beginning of this thread was started on [hidden email].) BTW, I made some mods to some classes to support pictures: MAFileUploadComponent subclass: #MMAPicFileUploadComponent instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'MMAApp'! !MMAPicFileUploadComponent methodsFor: 'rendering' stamp: 'jtc 6/8/2009 17:44'! renderEditorOn: html self value isNil ifFalse: [ html table: [ html tableRow: [ html image id: 'XXX'; document: self value contents mimeType: self value mimetype]. html tableRow: []]]. self isMultipart ifTrue: [ self renderUploadOn: html ] ifFalse: [ self renderRemoveOn: html ]! ! <<<<<<<<<<<<<<<<<<This will put the picture in the editor>>>>>>>>>>>>>>>>>>>>>>>>> MAFileDescription subclass: #MMAImageFileDescription instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'MMAApp'!

He was referring, I think, to Squeak vs. GemStone vs. VisualWorks vs.
Gnu vs. Dolphin (and so on).

That subclass is not really necessary, because you can reconfigure any description instance to use your customized view: MAFileDescription new reportColumnClass: MMADescribedImageColumn; componentClass: MADescribedImageComponent; .... > html image > id: 'XXX'; > document: myValue contents mimeType: myValue mimetype Something like this used to be part of Magritte. However, your table or form will "explode" if you upload a typical 12 MB picture ;-) I guess to make this really useable you need some code to resize the picture accordingly. And this is unfortunately not possible on different Smalltalk dialects in a platform independent way.
