News from the MBS Xojo Plugins Version 21.2

In this article I want to introduce you the new functionalities from the MBS Xojo Plugins in version 21.2.

Let’s start with RabbitMQ. We add a new RabbitMQ plugin part to wrap the open source RabbitMQ C library and bring the functionality to Xojo.

RabbitMQ itself is an open-source project implementing a message-broker software. It's a server software to do message queues and then there are various clients available to use the services.

We got a couple of classes for you:
The connection class allows to connect and then use the services. This includes managing queues and exchanges, so you can declare a new queue if needed. Then you can send messages to the queue or receive messages. We already got 10 example projects made for you to try the various things by translating a few C examples. Since you can install RabbitMQ yourself on a local VM, you can just try it locally. We include OpenSSL library, so you can use with and without SSL options. As usually the plugin handles memory and error management and hides a couple of low level stuff, especially all the value serialization with arrays, tables and variants.


Release notes for our Xojo plugins

Sometimes clients ask what has changed for a specific plugin in the last year. Especially if clients think whether they should renew plugins we sell separate like ChartDirector. There is a lot that changes over time as you can read in release notes:

As you see, quite a few changes in each release are related to one of the four plugins listed separately for release notes.

In general you want to stay up to date and not waste your time hunting for a bug we fixed months ago.

Let us know if you have questions.

MonkeyBread Software Releases the MBS Xojo Plugins in version 21.2

Nickenich, Germany - (May 18th, 2021) -- MonkeyBread Software today is pleased to announce MBS Xojo Plugins 21.2 for macOS, Linux and Windows, the latest update to their product that is easily the most powerful plugin collection currently available for Xojo. MBS Xojo Plugins have been updated and now includes over 2800 classes and 73,000 documented features, and the versatile plugins have gained more new functions:

ChartDirector 7 arrived. We include 17 new example projects to show new features including Treemap chart, Discrete Heat Map, Circular Bar Meter, Multi-Page PDF Output, Huge Data Set Support and High DPI Support. We added CDViewPortControlBaseMBS class and the new RealTime ViewPort example.

We have a new plugin for RabbitMQ. This is an open-source project implementing a message-broker software. It's a server software to do message queues and then there are various clients available to use the services. Our plugin wraps the library for Xojo and includes OpenSSL for encrypted connections.

For our AVFoundation Plugin we added AVCaptureMetadataOutputMBS class, which allows you to scan barcodes with the camera on an iOS device. For iOS we got an example on how to use Keychain database to store passwords securely.

Our JavaScriptEngineMBS class can use InitModules method to define modules in JavaScript, which can then be referenced later with require.

We got a new ContainerControl example showing you how to use NSScrollViewMBS to smoothly scroll a list of container controls. We include Windows support by using a Xojo scrollbar.

For SQL Plugin we got support in SQLite for ICU libraries and we enabled math and geopoly functions in our internal SQLite library.

We added new properties to NSSharingServiceMBS class, so you can for example pass styled text via NSAttributedStringMBS class to Apple Mail and get a formatted text in the email.

For Windows we got classes for spell checking. Use WinSpellCheckerMBS class to find available languages, pick one and check for spelling errors in a given text.

Our plugins now include universal library for iOS Simulator for Xojo 2021r1.1. We got a CopyCellValue function for XLSheetMBS class class to copy cell values within a sheet. We upgraded our ShellMBS and WindowsProcessMBS classes for Windows to allow PowerShell.exe to run with them.

Finally updated CURL to version 7.76.1, DuckDB to 0.25, DynaPDF to, HIDAPI to 0.10.1, LibJPEG-Turbo to 2.1.0, PortAudio to 19.7.0, SQLAPI to version 5.1.4 with new DuckDB support and our Linux build machine to Ubuntu 18.04.

Smooth scrolling list control with ContainerControls

Recently I implemented NSCollectionViewControlMBS control for Xojo to have a grid of items based on container controls. But a few days ago we had the need for having just a few containers to scroll on a window in Xojo. You may start to implement this in Xojo with a scrollbar and then move in the ValueChanged the containers up/down as needed. Quickly you may realize you need a wrapping container to clip the scrolling ones properly. But if you loop over containers and change their Top property to move them around, you may quickly see the scrolling not be smooth. We needed something better.

Since macOS comes with a NSScrollView class, I wanted to use that to push the job of scrolling and redrawing to the OS itself. So we have a Xojo managed inner and outer ContainerControl and slide our NSScrollViewMBS object between. We put all item containers on the inner ContainerControl, so Xojo may not know about the scrolling and just sees a big container in a smaller one. We configure the scroll view with a vertical scrollbar, some bezel around and a reasonable page scroll value.

When we try this setup, we can scroll smoothly and with mouse wheel support. We get the elastic scrolling with bouncing on the ends (can be disabled). This is fantastic and very smooth.

You may ask about Windows and Linux. Well, this may also be doable, but then with a regular Scrollbar itself. It may be tricky to get the redraw stuff smooth and avoid flicker. But well, I made an example for that, too. Tested on Windows and seems to work mostly with scrollbar controls. Since we only move the inner container up and down and let the container do clipping, it seems to work well with not much flicker.

And once I had that, I merged the two examples into one. Please try it soon as part of the examples coming with MBS Xojo Plugins in version 21.2pr7 or later. If you have feedback and improvements, feel free to send them back to us, so we can merge your changes into our example.

Bitsundso Download

For everyone watching regularly the Bitsundso Plus stream, we got a nice utility app (made in my spare time) to download the current episode as video:

You can download current version here: BitsundsoDownload.dmg

You need to specify the ID and password for the login. Than you specify where the ffmpeg command line tool is and where to store the video file. By default it will be put on desktop. Our tool just performs a login on Bitsundso website, gets the video stream URL, picks the 720p stream and downloads it by running ffmpeg. It shows you progress and opens video file on the end. Settings are saved for next run, so you can just run it every week, when you got the push for the new episode.
We have it in use for years now. With this update Apple Silicon is included and we made adjustments for Big Sur. Great for offline watching.

Have fun!

Did you know that Xojo has a problem with basic math? Neither did Markus, until he fell down a programming black hole that led him to obscure 32-bit/64-bit oddities.

FileMaker-Like Checkboxes by Vince Du Beau
Vince wanted checkboxes in Xojo like he was used to having in Filemaker—so he wrote his own class to add them.

Holy Cryptography, Batman! by Eugene Dakin
If you're curious about cryptography, here's low-key introduction as Eugene starts a new series of articles beginning with the ancient Caesar Cipher.
