It's possible to embed the editor on an existing page or add an action to open the editor in a separate page.

Editor Action

The easiest way to implement the editor is to open it by an action.

Here is an example of adding the actions:

action(ActionRichTextEditor)
{
    ApplicationArea = CCSTMRTE;
    Caption = 'Rich Text Editor';
    Image = DocumentEdit;
    Promoted = true;
    PromotedCategory = Process;
    PromotedOnly = true;
    ToolTip = 'Open the rich text editor for the selected line.';

    trigger OnAction()
    begin
        OpenRichTextEditor(false);
        CurrPage.Update(false);
    end;
}
action(ActionRichTextEditorLineConversion)
{
    ApplicationArea = CCSTMRTE;
    Caption = 'Rich Text Editor (Line Conversion)';
    Image = DocumentEdit;
    Promoted = true;
    PromotedCategory = Process;
    PromotedOnly = true;
    ToolTip = 'Open the rich text editor for the selected line and convert the text into plain text document lines, afterwards.';
    Visible = PageEditable;

    trigger OnAction()
    begin
        OpenRichTextEditor(true);
        CurrPage.Update(false);
    end;
}

Here is an example of calling the editor on action:

local procedure OpenRichTextEditor(LineConversion: Boolean)
var
    TempRichTextLine: Record "CCS TM Line Document" temporary;
begin
    TempRichTextLine.Copy(Rec, true);
    OpenRichTextEditor(TempRichTextLine, LineConversion, CurrPage.Editable);
end;

procedure OpenRichTextEditor(RichTextLine: Record "CCS TM Line"; LineConversion: Boolean): Boolean
var
    RichTextEditor: Page "CCS TM Rich Text Editor";
begin
    RichTextEditor.SetContent(GetRichText(RichTextLine, RichTextLine.FieldNo("Rich Text")));
    RichTextEditor.SetRequestPageId(Page::"CCS TM Subform");
    RichTextEditor.SetEditable(true);
    if RichTextEditor.RunModal() = Action::OK then begin
        SetRichText(RichTextLine, RichTextEditor.GetContent());
        SetLineText(RichTextLine, RichTextEditor.GetText());
        RichTextLine.Modify();
        DeleteChildLines(RichTextLine);
        if LineConversion then
            ConvertLines(RichTextLine, RichTextEditor.GetText());
        exit(true);
    end;
end;

The line conversion will not be handled in detail. Check codeunit 5060608 "CCS TM Rich Text Management" for details.

Embedded Editor

The CCS TM Rich Text Editor user control defines the rich text editor. To embed the editor on an existing page, the user control must be added, and saving and loading the content must be handled.

Here is an example of adding the user control:

group("CCS TM Rich Text Editor Group")
{
    Caption = 'Rich Text Editor';

    usercontrol("CCS TM Rich Text Editor"; "CCS TM Rich Text Editor")
    {
        ApplicationArea = CCSTMRTE;

        trigger OnControlAddInReady()
        var
            Management: Codeunit "CCS TM Rich Text Management";
        begin
            CurrPage."CCS TM Rich Text Editor".InitializeEditor(Management.GetEditorToolbarString(Page::"Extended Text"));
        end;

        trigger OnEditorInitialized()
        begin
            EditorInitialized := true;
            LoadContentToEditor();
        end;

        trigger OnEditorChange(Content: Text; Text: Text)
        begin
            SaveContentFromEditor(Content);
        end;
    }
}

Here is an example of handling the saving and loading of content:

trigger OnAfterGetCurrRecord()
begin
    LoadContentToEditor();
end;

local procedure UpdateControls()
begin
    if EditorInitialized then
        CurrPage."CCS TM Rich Text Editor".SetReadOnly(not Editable);
end;

local procedure LoadContentToEditor()
var
    Content: Text;
    InStr: InStream;
begin
    if not EditorInitialized then
        exit;

    Rec.CalcFields("CCS TM Rich Text");
    Rec."CCS TM Rich Text".CreateInStream(InStr);
    InStr.Read(Content);
    CurrPage."CCS TM Rich Text Editor".SetContent(Content);
end;

local procedure SaveContentFromEditor(Content: Text)
var
    OutStr: OutStream;
begin
    if StrLen(Content) > 0 then begin
        Clear(Rec."CCS TM Rich Text");
        Rec."CCS TM Rich Text".CreateOutStream(OutStr);
        OutStr.Write(Content);
    end else
        Clear(Rec."CCS TM Rich Text");
end;

To convert lines, you can listen to an event of the user control:

trigger OnConvertToLines(Content: Text; Text: Text)
begin
    ConvertLines(Text);
end;

The conversion implementation could look like this:

local procedure ConvertLines(EditorText: Text)
var
    Line: Text;
    LineLine: Text;
    Lines: List of [Text];
    LineLines: List of [Text];
    Management: Codeunit "CCS TM Rich Text Management";
    NextLineNo: Integer;
    ExtendedTextLine: Record "Extended Text Line";
begin
    DeleteChildLines();
    NextLineNo := 1;
    Management.ConvertTextToLines(EditorText, Lines);
    foreach Line in Lines do begin
        Management.SplitTextToLines(Line, MaxStrLen(ExtendedTextLine.Text), LineLines);
        foreach LineLine in LineLines do begin
            CreateLine(NextLineNo, LineLine);
            NextLineNo += 1;
        end;
    end;
end;

local procedure CreateLine(LineNo: Integer; Value: Text)
var
    ExtendedTextLine: Record "Extended Text Line";
begin
    ExtendedTextLine."Table Name" := Rec."Table Name";
    ExtendedTextLine."No." := Rec."No.";
    ExtendedTextLine."Language Code" := Rec."Language Code";
    ExtendedTextLine."Text No." := Rec."Text No.";
    ExtendedTextLine."Line No." := LineNo;
    ExtendedTextLine.Text := Value;
    ExtendedTextLine.Insert();
end;

local procedure DeleteChildLines()
var
    ExtendedTextLine: Record "Extended Text Line";
begin
    ExtendedTextLine.SetRange("Table Name", Rec."Table Name");
    ExtendedTextLine.SetRange("No.", Rec."No.");
    ExtendedTextLine.SetRange("Language Code", Rec."Language Code");
    ExtendedTextLine.SetRange("Text No.", Rec."Text No.");
    if not ExtendedTextLine.IsEmpty then
        ExtendedTextLine.DeleteAll();
end;
