4.x Data Grid Editing - material-ui

I am currently on the licensed 4.x version and looking to add Datagrid editing capability. I am not in a position to move my app to 5.x. DataGrid editing examples in am looking in 4.x documentation shows the import
#mui/x-data-grid-pro
Is this compatible with 4x #material-ui/core
I tried intalling
#mui/x-data-grid-pro
but getting errors with some grid api methods (GridrowId import)

MRTK 2.0.0 - WMR Controller Model and Shader not included?

The newer versions of MRTK-vNext (v2.0.0 Beta 2), don't seem to contain the ability to load the native Controller meshes & shaders. Is there anyway to get these implemented like older versions, or is this something that will be added in the -near- future? The MixedRealityConfigurationGuide states:
The MRTK does not currently support native SDK's controller models as Unity does not yet provide the capability to load / render gLTF models, which is the default type of models provided by most SDKs. This will be enhanced when this is available.
However, previous versions of the HoloToolKit seemed to have this implemented? I can understand why controllers for Oculus and OpenVR haven't been implemented yet, but why not the WMR ones. Is there anyway to add the older methods into a project running V2.0.0 Beta 2?
The main issue with the native models is with their format, Unity does not support "out of the box" gLTF models. Each SDK that uses them (including steam now) has had to write their own implementation.
The feature is coming very soon (if not merged already) in to the MRTK development branch and will be available for the upcoming RC1 release. This however, will only feature the model and not the animations (as things change), but this will also be included later.
In the meantime you can place the default Gizmo models with any other model of your choice in the "Input Settings" -> "Controller Visualisation" configuration.
Here's a quick guide to managing controllers - https://www.youtube.com/watch?v=F3e2lwqVPyc
There is an initial pull request out to address this issue:
https://github.com/Microsoft/MixedRealityToolkit-Unity/pull/3548
This functionality took longer to port based on HTK's gltf importing logic using a newtonsoft library for json serialization. Newtonsoft version conflicts paired with Unity's il2cpp compiling was generating issues for different MRTK community members. Luckily, another community member provided a unity json serialization based utility for gltf loading :)
This pull request will enable WMR controller models appearing in compiled windows/uwp applications. Additional work will be required to get these models appearing in the editor.

PlantUML does not render arrows well in a class diagram (Skinparam linetype ortho mode)

I'm trying to make some complex class diagrams with PlantUML by having ortho layout for the relations between the classes.
Some arrows, especially those which are connected at the bottom of an element does not rendered very well.
If it is important, I use VS Code with jebbs.plantuml extension.
Anybody with the same experience?
Problem looks like to be due to an old version of plantuml. The newest released version can be found through the plantuml main page http://plantuml.com/ on http://plantuml.com/download.
The latest available plantuml.jar beta file: http://beta.plantuml.net/plantuml.jar (at http://beta.plantuml.net/ you might also find other files of the latest beta version)
I resolved the problem with installing the latest version of Plantuml.jar as well as latest version (2.38) of Graphviz.
It looks like I used the older one (2.28)
Thank you for the help.

Chart and graphs

I am using iTextSharp version 4.1.2 and cannot update to newer version because iText changed
their licence agreement.
I am very satisfied with this version and it's working fine for me.
I can't find anywhere how to produce pie or bar or columns graphs and charts
with that version and looks like all documentation over the internet been removed.
If you are using older version and by the chance you have documentation can you please share
or point me to the source, or explain how?
iText doesn't have built-in support for charts or graphs. Instead you are encouraged to use a 3rd-party library to generate these and then add them as either graphics or PDFs.
Another option as outlined in this post is to use the iTextSharpExtensions. Please note that although it has the word "iText" in it is in no way endorsed by the makers of iText.
Also, as a quick side note, please read FAQ, specifically the "Why shouldn't I use iText 2.x (or iTextSharp 4.x)?" explaining some of the myths of the license of the version you are using.

blackberry cascades mapview

Hi I am trying to implement a mapview using blackberry cascades based on this link but whenever I import maps
import bb.cascades.maps 1.0 ,
the QNX IDE throws out an error saying
bb.cascades.maps is not installed.
I have set up the environment exactly as described in the developer site and dont seem to understand how do i install this module.
They seem to have left out some steps. Not all cascades objects are loaded by default into the development system, but they can be added at runtime. The biggest drawback is that the Eclipse can't do static analysis of the QML for errors only general syntax.
If you add the following lines to the main.cpp file you may get the example to work (I hacked this into one of my current projects and got it to load without errors but the MapView is all black):
#include #include <bb/cascades/maps/MapView>
Then just before the QmlDocument::create call:
qmlRegisterType<bb::cascades::maps::MapView>("bb.cascades.maps", 1, 0, "MapView");
This is the mechanisim that is used quite frequently to make Cascades objects not included in the default setup available, or to make your own specializations from CustomControl or other Cascades objects available to QML.
Finally this example seems to pre-date beta 3 so there may be some other issues that you may have to work through.
EDIT
I did some poking around and found this thread on the BlackBerry forum. Setting the altitude to 10000 actuall got me a usable map on the simulator and the Dev Alpha. It obviously needs more work but you can interact with it (drag to move, pinch to zoom, etc).
The MapView component seems to have been largely unusable until the most recent SDK update (10.0.9.2318), as somewhat admitted and referenced by this Blackberry DevBlog post:
http://devblog.blackberry.com/2013/01/cascades-mapview/
Also, check out the new CustomMapView example on Github for a working sample app using this latest update:
https://github.com/blackberry/Cascades-Samples/tree/master/custommapview
For the QML preview issue, this is known issue. QML Preview currently only supports the core cascades components. See my more detailed answer here:

What WYSIWYG editor does xWiki use?

Which WYSIWYG editor is used by xWiki? And was it ever using a different one? In which version did it change?
There are two WYSIWYG editors in the current (3.0-milestone-2) release: an older (now deprecated) one based on TinyMCE, and a GWT-based editor developed in-house, introduced in 1.7 (see http://platform.xwiki.org/xwiki/bin/Features/PageEditing#HWYSIWYGeditingmode and http://platform.xwiki.org/xwiki/bin/Features/WysiwygEditor for more details). Back in the very early days of XWiki (2005), there was another editor based on HTMLArea, but it was quickly replaced by TinyMCE.
So, the current editor is not an external one, but a custom developed one, available under the LGPL 2.1 license.
