The GeoGebra extension allows to use GeoGebra applets on a page.
GeoGebra applets use Java technology to combine an interactive geometry environment with the ability to directly enter equations and coordinates making it very useful in math education and math explorations.
GeoGebra applets and worksheets are shared at: www.geogebratube.org (community)
Usage[edit | edit source]
You can export a GeoGebra file to a wiki very comfortably (since GeoGebra 22.214.171.124).
Use the export function of GeoGebra:
Choose File - Export - Dynamic Worksheet as Webpage...
Then go to "Advanced" and choose "Clipboard:MediaWiki" (bottom right).
See the tutorial at wiki.geogebra.org: GeoGebra with MediaWiki
Paste the clipoard to your wiki in edit mode. Done! This will create a tag like this:
<ggb_applet height="300" width="600" ggbBase64="AbCd67Fg...KhRs" />
Upload of ggb files to the wiki is obsolete and not longer supported!
You can also pass GeoGebra applet parameters. See Parameters
<ggb_applet height="200" width="400" showMenuBar="true" showResetIcon="true" ggbBase64="AbCd67Fg...KhRs" />
Installation[edit | edit source]
- Download and extract the files in a directory called
- Add the following code at the bottom of your LocalSettings.php:
- Done – Navigate to "Special:Version" on your wiki to verify that the extension is successfully installed.
Note: If you are using an older version (<= 1.16.x) of MediaWiki, you will have to use an older version of this extension. Version 2.7i can be found at an older version of this page
Support of mobile devices since version 3.0d-web[edit | edit source]
GeoGebra applets using the syntax 'filename="xyz.ggb"' (obsolete) are delivered only as Java applets.
You can force the delivery of HTML5 by using the parameter ?mobile=true appended to the URL. Use &mobile=true if there is already a ? in the URL.
Version 3.0d-web installed at wikis.zum.de[edit | edit source]
Support of mobile devices now can be testet at wikis.zum.de/zum.
Status changed back from stable to beta[edit | edit source]
Wiki admins: Please install and test latest version 3.0d-web.
Version 2.7 was tested with with many wikis, without critical errors. Status of Version 2.7i was changed from beta to stable at 2011-03-05.
Version 3.0d-web is installed at other wikis since 2013-12-01. Carefully I changed status back to beta at 2012-08-09.
Incompatibility with MediaWiki 1.19 fixed[edit | edit source]
Zbynek Konecny from the GeoGebra team told me that this line did not work after updating to MediaWiki 1.19:
- $ggbFile = Image::newFromName($ggbBinary);
Fixed with version 2.8a.
