  • 2020-05-24 Blog Post by Ideas Awakened Delphi 10.4 Sydney is the best tool for creating Windows Applications

  • 2020-05-25 Blog Post by Erik van Bilsen Boost Mac performance with Metal and Delphi 10.4

    • Latest changes in 10.4 help to address the slow native GUI render performance on macOS
    • Delphi still defaults to using CoreGraphics, CoreText and OpenGL for backwards compatibility reasons
    • To activate, set GlobalUseMetal := True; in your DPR, before forms are created. (Ensure FMX.Types is also added to DPR)
    • Be aware that using Metal will disable the use of CoreText for text layout, and use TGPUTextLayout instead but that currently doesn't support advanced layout features, bi-directional text, nor language-specific line breaking.

      • Count population
    • TCustomIniFile has new methods: WriteInt64, ReadInt64
    • TGUID has a new IsEmpty method
    • The Items property of JSONArray is now a default property simplifying code (myJArray[2] instead of myJArray.Items[2])
    • Multiple performance improvements in the RTL were listed
    • The signature for FreeAndNil was updated to generate a compiler error for unsupported types, helping to prevent hard to find bugs. This is a very nice improvement with no obvious downside.
    • Specific changes listed to focus on for potential change in behavior:
      • The CopyFrom function of TStream has a larger default buffer (was 60KB and is now 1MB) and the method now exposes a new parameter so you can override this default buffer size
        • function CopyFrom(const Source: TStream; Count: Int64 = 0; BufferSize: Integer = $100000): Int64;
      • TStringHelper.GetHashCode has been updated to no longer uppercase the string before hashing it

  • 2020-05-15 Blog Post by Uwe Raabe Delphi 10.4 leverages VCL Styles

    • VCL Styles: support added for High DPI styles leveraging TVirtualImagelist connected to a TImageCollection

  • 2020-05-15 Blog Post By Marco Cantu VCL Per-Control Styles Coming in RAD Studio 10.4

    • To start, you need to add multiple styles to an application, and one needs to be active
    • This feature is controlled by a new StyleName property for the TControl class.
    • By default, TControl.StyleName is empty and control uses a default style.
    • You can define a specific style also for common dialogs. Use the property TStyleManager.DialogsStyleName By default, it is empty and common dialogs use the default style of the application.
    • When you set the TStyleManager.UseSystemStyleAsDefault to true: if some control or form has an empty StyleName property, then it will always use 'Windows' style and VCL Style will be always disabled on it. (Helps with third party controls styling)
