When it comes to bringing web applications to a desktop enviroment the choice falls on Electron as it’s the most popular framework among web developers. We offer support for Electron applications already, but the downside is always there: it’s a 3rd party solution that we have no control over. At the end of the last year we asked ourselves if we can provide an alternative that fits us better. A few months later here we are about to release a beta version of TMS WEB Core v1.7 with Miletus! What is Miletus exactly? Named after Thales of Miletus, Miletus is a framework that enables TMS WEB Applications to run as desktop applications and it also provides access for native features. In a nutshell, you can fully reuse code created for a web application, take advantage of HTML/CSS for creating a modern & spectacular responsive user interface, access local files & local databases or closely integrate with operating system capabilities and still easily deploy the application as standalone executable. Our colleague Holger Flick explains it in more detail how one could create such Miletus application with TMS WEB Core: Let’s take a look at the available classes, functions and components that will enable you to interact with native operating system functionalities! Classes and functions TMiletusStringList: Read and write local text files. TMiletusBinaryDataStream: Similarly to TMiletusStringList this enables you to write and read local binary files. It also provides multiple formats to access the data. TMiletusClipboard: Read from and write to the OS clipboard. TMiletusShell: Exposes some shell functionalities: open a file with its default application, open an external URL with the default browser, move files to the trash and show files in the containing folder. GetCursorPos: Returns the position of the cursor. GetMiletusPath: Returns the common paths. StartFileDrag: Start dragging a file from your application to any destination where the file is accepted. Components TMiletusOpenDialog: Displays a native open dialog and returns the selected path(s). TMiletusSaveDialog: Similarly to TMiletusOpenDialog, it displays a native save dialog and returns the selected path. TMiletusMessageBox: Shows a native message dialog. The labels, the dialog type, the buttons and the verification checkbox are all customizable. TMiletusErrorBox: Shows a native error message dialog. TMiletusMainMenu: Creates and appends a native main menu to the form where it’s dropped. TMiletusPopupMenu: Creates and displays a native popup menu  TMiletusNotificationCenter: Allows you to show notifications on the operating system.  TMiletusWindow: Allows the creation of multiple application windows which can be linked to forms or other sources. TMiletusTrayIcon: Creates a tray icon on the OS tray. An optional popup menu can be assigned to it. TMiletusFileWatcher: Monitors a list of files for changes. Each file has its own event handler which will be triggered when the file has changed. TMiletusGlobalShortcuts: Add a list of keyboards shortcuts that will be recognized even when the application is not in focus.  What about database support? We also added support for local databases! The component TMiletusClientDataSet makes it easy for a Miletus application to create and use local databases by a familiar syntax of using TClientDataSet. It also allows a seamless integration of multiple types of databases with data-aware components like TWebDBGrid, TWebDBTableControl, TWebDBEdit etc… All the database operations can be done in the standard Delphi way through the TMiletusClientDataSet component.  We prepared 5 database drivers to […]

Intro There are a lot of things going on in the TMS labs at the moment. We announced a lot of great improvements and new features for the upcoming TMS WEB Core 1.7 (https://tmssoftware.com/site/blog.asp?post=772) as well as a couple of past and future platforms FNC runs on (April Fools’ Day joke …). Today we are proud to announce a new platform is coming for FNC. (NOT an April Fools’ Day joke !). Sneak preview Before we want to announce exactly which platform is going to be supported in all it’s glory, here is a sneak preview. What’s coming? FMXLinux official support is coming in the near future! We are currently working hard to make all FNC components compatible with FMXLinux which means there will be a TTMSFNCWebBrowser based on WebKit (https://webkitgtk.org/), a REST based TTMSFNCCloudBase working with Curl (https://curl.se/), PDF export based on our own implementation and much much more! Of course, you can also expect all components that are working based on TMS FNC Core to have FMXLinux support. Stay tuned for more info coming real soon!

What’s new?  The second TMS FNC Maps update of 2021 includes integrated directions for Google Maps and MapKit along with map rotation in TTMSFNCMapKit. Introducing TTMSFNCMapKit A new stand-alone component for Apple MapKit JS is available in TMS FNC Maps v1.4.: TTMSFNCMapKit includes integrated directions and map rotation as component specific features with more to come in the near future. Integrated directions with step by step instructions TTMSFNCGoogleMaps and the new TTMSFNCMapKit component now include support for directions out of the box. All you have to do is drop one component on the form, assign a valid API Key and you’re good to go! Addresses and locations are geocoded automatically and the calculated route is displayed on the map with just a single line of code.     TMSFNCMapKit1.AddDirections(‘New York’, ‘Washington DC’); Optional configuration parameters are available including but not limited to: Polyline color and width Hide markers or polyline or both Indicate if travelling by car or on foot Also, step by step instructions and route details (displayed in the bottom-left corner of the screenshot below) are returned in an event.  Map Rotation Another new feature exclusive to the TTMSFNCMapKit component is the ability to rotate the map programmatically. Again with only one line code the rotation of the map can be changed.   TMSFNCMapKit1.Options.MapRotation := TMSFNCMapKit1.Options.MapRotation + 45; Update Now! Update now to get all the latest and greatest TMS FNC Maps updates and get started exploring the new features!

We have a new major release of the TMS FNC UI Pack, next to some fixes and new features, we have added the TTTMSFNCHotSpotImage to the already extensive set of powerful and feature-rich UI controls that can be used cross framework and cross platform with just one code base. TMS FNC Controls can be simultaneously used on these frameworks: TMS FNC Controls can be simultaneously used on these operating systems/browsers:TMS FNC Controls can be simultaneously used on these IDE’s:   TTMSFNCHotSpotImage This component is already known to VCL and FMX users and for the TMS WEB Core users who don’t know the component, you can compare it with the idea of an Image Map. The TTMSFNCHotSpotImage (further referred to as ‘hotspotimage’) gives you the ability to choose one image and then add different areas (hotspots) with which you can interact and each of them can have their own appearance. TTMSFNCHotSpotImageEditor Our team considers the convenience of visually creating and configuring your components, that is why an editor was created to help you design your hotspots. This can be done in designtime by a double click or right-click on the hotspotimage. To give you full control over your hotspotimage, the editor is also available in runtime. Hotspotimage Demo To let you get more familiar with the component, we have created a demo application that you can find here. This topic describes the steps we have taken to create such a demo application. It is a simple example of a selection game that shows a lot of features. You’ll need to find the correct country for a given capital. The TTMSFNCHotSpotImageEditor (further referred to as ‘hotspotimage editor’) can be used to create the hotspots of the different countries. All of the following can be done in the code as well. But to give an example of the possibilities, we will explain how to this visually. The image can be added in the editor or with the Bitmap property. On the top of the editor there is a toolbar that can be used to create or manipulate the poylgons. Because there is a high contrast and the edgy shape of the different countries, the Magic Wand was the perfect tool to create the polygons. In the panel on the right, you have the buttons ‘Hover’, ‘Selected’ and ‘Down’. With these buttons you can change the appearance for the different states. If none of the hotspots are selected in the listbox, then you are able to change the default appearance used on newly created hotspots in the different pages. On the other hand, if you select a hotspot, you can change the appearance for the specific hotspot. This way, I’ve changed the Fill kind of the polygon to a texture with an image of the flag. You can also change the stroke and font used by the hotspot. To change the name of the different hotspots, select the hotspot in the listbox, edit the text in the edit box and click on the ‘Change Name’ button. Now let’s have a look at the code that is used. Besides the code used to change the settings between game mode and normal selection mode, only two specific events are needed. The event OnSelectedHotSpotChange where the check is added to see if the selection is allowed.As it would not be helpful to unselect a hotspot while playing the game. […]

TMS XData 5 has been released with lots of new features! Photo by Glenn Carstens-Peters on Unsplash In addition to the recent release of TMS Aurelius 5, a new major version of TMS XData has been also released. TMS XData 5 is the fifth major version of our framework to build multitier applications, including REST API server, and interface-based API client. It makes it easy to build server-side services that reach a broad range of clients, including browsers and mobile devices. Among several features, TMS XData provides: Automatic serialization/deserialization of pure Delphi objects, primitive types, method parameters; Authentication and Authorization; Powerful routing mechanism: route endpoints to methods in your code; Automatic, zero-code Swagger/SwaggerUI support; Interface-based client allows type-safe client applications without additional code; Smooth TMS Aurelius integration allows CRUD endpoints of database entities automatically. The new features released with XData 5 were also antecipated in a previous blog post, The what’s new section in the documentation provides you with a full list, but here we will list a few: Attribute-based Authorization Developers will be able to just add authorization attributes to methods (service operations) or entities (automatic CRUD endpoints) and everything will be applied accordingly. Fine-tuning the protection of your REST API will never be as simple. [Authorize] IDocumentService = interface(IInvokable) procedure Insert(Value: TDoc); [AuthorizeScopes(‘user, editor’)] procedure Modify(Value: TDoc); [AuthorizeScopes(‘admin’)] procedure Delete(DocId: string); [AuthorizeClaims(’email’)] procedure Approve(DocId: string); end; In the example above, all methods (endpoints) require authentication, because the interface has an Authorize attribute that propagates to all methods. So, to invoke Insert, user must be authenticated. Still, to invoke Modify, the user must be authenticated and have either user or editor scope in its credentials. He must be admin to invoke Delete, and finally to approve a document, user must have an email in its claims. It’s also worth noting that the same strategy applies to entities that generate automatic CRUD endpoints: [Entity, Automapping] [EntityAuthorize] [EntityAuthorizeScopes(‘editor’, [TEntitySetPermission.Modify, TEntitySetPermission.Insert])] [EntityAuthorizeScopes(‘admin’, [TEntitySetPermission.Delete])] TCustomer = class {…} public property Id: Integer read FId write FId; property Name: string read FName write FName; end; To access customer endpoints, user must be authenticated. But he must have editor privileges to modify and insert (PUT and POST) and must be admin to invoke DELETE. Easy and straightforward. Async/Await Support in Web Applications TMS XData is smoothly integrated with TMS Web Core, the TMS framework to build web applications. Now your can use async/await mechanism in TXDataWebClient methods that invoke XData server endpoints. As an example, invoking a XData REST API endpoint asynchronously will be as easy as doing this: PendingOrders := await(XClient.List(‘$filter=Status eq pending’)); if PendingOrders.Count = 0 then Exit; // no pending orders to process The single line above will build the HTTP request with proper URL endpoint and HTTP method, invoke it, deserialize the returned JSON into a list of TOrder objects, and all asynchronously! The await function will guarantee that the next line will be executed only after the async execution is executed. Can’t get easier than that. Multitenant Servers This is a feature released with TMS Aurelius, which now has the global filter mechanism, allowing you to build multitenant applications. But XData now includes a few nice mechanisms to integrate with such Aurelius filters that makes building multitenant servers very easily! From a single handler for the event OnManagerCreate, you can […]
