Powerful new memo component for Delphi


Tuesday, January 31, 2023

It's been a while since we first introduced a TMS FNC UI Pack beta for all our active ALL ACCESS users. The beta gave access to a brand new development: TTMSFNCMemo. Along the way, we received a lot of valuable feedback, finetuned existing features at the time of the beta release and meanwhile also added a lot of new features. People have been asking for a cross-platform syntax highlighting memo. With the increasing popularity of Visual Studio Code, we started investigating if we could integrate this into a FNC Component. With the use of WX Pack technology, we were able to wrap this in a component and expose the functionality to our users. The memo is based on the JavaScript based Monaco Editor. Today, we are proud to present the first official release of TTMSFNCMemo.

The TTMSFNCMemo has a ton of features, below are the most important ones. Before going through the features below, important to know is that we developed this component with compatibility in mind. Compatibility with TMemo. When using this component you'll find that it has striking similarities on how a TMemo is operated especially programmatically. The most important feature is that there is a Lines property that is used to handle all text operations, just like in a normal TMemo.

Code Completion

The editor registers variables and keywords inside the editor and you can use code completion to trigger them. As an added bonus, Javascript, HTML and CSS fully supported with a ton of browser APIs.

Breakpoints / bookmarks

Breakpoints / bookmarks allow you to add a line based indicator. This can be done programmatically, or via interaction. Subscribe on the OnGutterClick event and implement the following code, to let the user set his own breakpoints. You'll need to enable GlyphMargins in the options property of the TTMSFNCMemo.

procedure TForm2.TMSFNCMemo1GutterClick(Sender: TObject; LineNumber: Integer);
  TMSFNCMemo1.BreakPoints[LineNumber] := not TMSFNCMemo1.BreakPoints[LineNumber];


The TTMSFNCMemo supports Visual Studio Code based themes like shown in the screenshot below.

Find & Replace

Pressing CTRL+F or CTRL+H will trigger the built-in find & replace functionality. Alternatively, this can be executed programmatically as well.

BasicMemo.ReplaceNext(FindEdit.Text, ReplaceEdit.Text);

Online/Offline support

The TTMSFNCMemo uses a underlying browser to access the Javascript libraries, we served all files over the internet. By default, dropping the TTMSFNCMemo on the form requires internet access. If you don't have internet access or want to use the TTMSFNCMemo in an environment without internet, the LibraryLocation will allow you to set it to offline.
