Update of /cvs-repository/Zope3/lib/python/Zope/App/OFS/Image/Views/Browser
In directory cvs.zope.org:/tmp/cvs-serv10334/Image/Views/Browser
Added Files:
Tag: srichter-OFS_Formulator-branch
ImageData.py ImageEdit.py __init__.py browser.zcml edit.pt
Log Message:
Okay, I am finally ready to check this stuff in:
- Reorganized the internal directory structure of every content object. For
each content object you have now a Views directory that contains further
directories for different protocols, such as Browser (HTML), XUL, FTP ...
Note: None of the directories is file-type, but functionality-based. It
is a bad idea to create directories for a particular file type, as
it was common in Zope 2.
- Made Folder, File and Image forms Formulator-based. This allows us now to
create forms for new protocols. such as XUL very quickly (often just a
few lines of code). More to Formulator when it is being checked in.
- Cleaned up most files. Almost all files should have now the correct
license disclaimer.
- A new object called LoadedFolder was added. LoadedFolder currently
provides two new functionalities to folders:
1. Ordering. You can change the order of the objects. This idea was
taking from the Zope 2 product OrderedFolders.
2. Limit. You can specify the maximal amount of items the folder is
allowed to store. This idea was also taken from OrderedFolders.
Note: Due to much rearranging during this development, there are no tests
yet written for this. This needs to be done, before we merge with
the Zoep-3x-branch again.
- Started XUL implementation of screens.
- Fixed some bugs I found lying around.

Generate an HTML IMG tag for this image, with customization.
Arguments to self.tag() can be any valid attributes of an IMG tag.
'src' will always be an absolute pathname, to prevent redundant
downloading of images. Defaults are applied intelligently for
'height', 'width', and 'alt'. If specified, the 'scale', 'xscale',
and 'yscale' keyword arguments will be used to automatically adjust
the output height and width values of the image tag.
Since 'class' is a Python reserved word, it cannot be passed in
directly in keyword arguments which is a problem if you are
trying to use 'tag()' to include a CSS class. The tag() method
will accept a 'css_class' argument that will be converted to
'class' in the output tag to work around this.
