1.2 lira 2:
1.1 www 3: This panel lets you set various display options for content.
1.2 lira 4: \begin{itemize}
5: \item Default XML style sheet
6: \item Visibly Separate Items on a Page
7: \item Disable Display of Problem Receipts
8: \item Force use of a specific math rendering engine
1.4 raeburn 9: \item Set default options for $<$m$>$ tags when
1.3 lira 10: converting \LaTeX{} to html.
1.9 raeburn 11: \item Student formula entry uses inline preview, not DragMath pop-up
12: \item Molecule editor uses JSME (HTML5) in place of JME (Java)
13: \item Chemical reaction response uses inline preview, not pop-up
1.10 ! raeburn 14: \item Display of external resources
! 15: \end{itemize}
1.3 lira 16:
1.5 raeburn 17: Style files (.sty extension) created in Authoring Space and published to the shared content pool
18: can be selected for use when rendering resources in the course by clicking the
19: \underline{Select Style File} link. See the ``Resource Types'' item in the ``Introduction to LON-CAPA
20: Authoring'' section in the Authoring manual for more information about .sty files. An alternative to
21: the use of .sty files is to create a CSS file (.css extension) in Authoring Space, and publish to the shared content pool. Note: in this case you would use a problem parameter ``CSS file to link (cssfile)'', accessed via Content Settings, instead of Course Settings, to apply the style to resource(s) in your course.
22:
23: Composite Pages include two or more resources on a single web page. By selecting ``Yes'' for
24: visible separation, adjacent resources will be separated by a horizontal rule.
25:
26: Problem Receipts will be displayed by default when feedback on correctness is being displayed to a student, and the student has submitted the correct solution. See the ``Verify a Submission Receipt Number'' section (\ref{Grade_Verify}).
27:
1.9 raeburn 28:
29: If ``Force use of a specific math rendering engine'' is set to none, then the math display mechanism used to render LaTeX within <m></m> tags is determined in the following order, with the first one set being the one in effect:
30: \begin{enumerate}
31: \item User's own personal preference set by the user hovering over the user's name at top left of a LON-CAPA page, and selecting Preferences $>$ Math display settings
32: \item Domain default set by a Domain Coordinator
33: \item System default set for the LON-CAPA version installed on the server (tth in 2.11 and earlier)
34: \end{enumerate}
1.5 raeburn 35: This can be overriden by setting the attribute display to one of \textbf{MathJax},
1.9 raeburn 36: \textbf{mimetex} (i.e., Convert to Images) or
37: \textbf{tth} (i.e., TeX to HTML) which will force a specific display mechanism.
38:
39: The behavior of the textboxes where students enter either an algebraic formula (formularesponse) or a chemical reaction (reactionresponse) is inherited from settings in the domain. The default, in the absence of a specific domain setting, is to use an inline preview which appears below the textbox, as the expression is typed. The domain default can be overridden within a specific course if it is preferred to use the old pop-up window displays in either case.
40:
41: Similarly, the the molecular editor display will use the domain setting, unless overridden within a specific course. If nothing is explicitly set in the domain or the course, then the default is to use JSME instead of its JME predecessor.
42:
1.10 ! raeburn 43: The Course Editor can be used to add the URL for an external resource to be displayed within a LON-CAPA course. By default, the remote content will be displayed in an iframe with standard LON-CAPA menu links/icons present in the page header above the resource. LON-CAPA attempts to gracefully handle mixed active content issues for external resources by injecting usehttp=1 into the query string for the LON-CAPA URL, in order to force serving of an http:// external URL in an http:// LON-CAPA page, where the LON-CAPA server uses https:// by default for all other pages. A separate session cookie which confers reduced rights is used when usehttp=1 is present in the query string because LON-CAPA's standard session cookie includes the 'secure' attribute.
! 44:
! 45: LON-CAPA also attempts to circumvent the lack of scrolling for multi-page PDFs in iframes on iOS by replacing inline display in an iframe with a link when viewing on a mobile device. Another instance where LON-CAPA replaces display of an external resource in an iframe with a link to display the resource in a separate browser tab is when Content-Security-Policy or X-Frame-Options prevent display in an iframe.
1.9 raeburn 46:
1.10 ! raeburn 47: The automatic display adjustments described above occur on a case-by-case basis depending on the external resource itself.
! 48:
! 49: The ``Display of external resources'' item can be used to force display of all external resources in a course in either a separate browser tab, or in a new browser window. In the latter case an optional width and height (in pixels) can be specified. When tab or window are selected, there is also an option to re-use the same (named) tab or window when displaying different external resources in a course in order to limit the number of tabs or windows which may be created by browsing in a single course.
