    how to cosume grpc in delphi vcl client?

    I never worked with grpc but, AFAIK, you should use a client thats support http/2, and put in body the generated protocol buffer based on .proto file of the api service. You can make a delphi record based on .proto struct and use the Erik Van Bilsen serialization code https://github.com/grijjy/GrijjyFoundation/blob/master/Grijjy.ProtocolBuffers.pas
  2. @Hans♫ I couldn't simulate your problem. I set up the same scenario you described in a blank project and the scroll worked perfectly. I also mounted on a TVertScrollBox and it worked perfectly. I'm using RAD Studio 11, but it works the same as in previous versions. Try simulating on a blank project to see where the problem is. I don't know what's going on, but maybe some other control is capturing the gesture...
  3. This is strange because the scrollbox does not use mousedown, mouseup, it uses gestures, and with hittest or without hit test in the components above, it should work in the same way.
  4. You can use OnClick normally with this code: uses FMX.Objects, FMX.Math, FMX.Math.Vectors; type TipControl = class(TRectangle) private const DEFAULT_MOVEMENT_TOLERANCE = 4; private FAbsolutePressedPoint: TPointF; FIsMouseDown: Boolean; FIsValidClick: Boolean; FLastMouseActivePoint: TPointF; FMovementTolerance: Single; function IsMovementToleranceStored: Boolean; protected function CheckHasValidClick: Boolean; virtual; procedure Click; override; procedure DoClick; virtual; procedure MouseDown(AButton: TMouseButton; AShift: TShiftState; X, Y: Single); override; procedure MouseMove(AShift: TShiftState; X, Y: Single); override; procedure MouseUp(AButton: TMouseButton; AShift: TShiftState; X, Y: Single); override; public constructor Create(AOwner: TComponent); override; property IsValidClick: Boolean read FIsValidClick; published property MovementTolerance: Single read FMovementTolerance write FMovementTolerance stored IsMovementToleranceStored; end; function TipControl.CheckHasValidClick: Boolean; function CheckIsMouseOver: Boolean; begin Result := FIsMouseOver and TouchTargetExpansion.MarginRect(LocalRect).Contains(FLastMouseActivePoint); end; begin Result := FIsValidClick and FIsMouseDown and CheckIsMouseOver and ((FMovementTolerance = 0) or ((PressedPosition.Distance(FLastMouseActivePoint) <= FMovementTolerance) and (FAbsolutePressedPoint.Distance(LocalToAbsolute(FLastMouseActivePoint)) <= FMovementTolerance))); end; procedure TipControl.Click; begin if Pressed then begin if not CheckHasValidClick then FIsValidClick := False; if IsValidClick then DoClick; end else DoClick; end; constructor TipControl.Create(AOwner: TComponent); begin inherited; FMovementTolerance := DEFAULT_MOVEMENT_TOLERANCE; FLastMouseActivePoint := PointF(-10000,-10000); end; procedure TipControl.DoClick; begin inherited Click; end; function TipControl.IsMovementToleranceStored: Boolean; begin Result := not SameValue(FMovementTolerance, DEFAULT_MOVEMENT_TOLERANCE, TEpsilon.Position); end; procedure TipControl.MouseDown(AButton: TMouseButton; AShift: TShiftState; X, Y: Single); begin FAbsolutePressedPoint := LocalToAbsolute(PointF(X, Y)); FIsValidClick := True; FIsMouseDown := True; FLastMouseActivePoint := PointF(X, Y); inherited; end; procedure TipControl.MouseMove(AShift: TShiftState; X, Y: Single); begin if CheckHasValidClick then begin FLastMouseActivePoint := PointF(X, Y); if not CheckHasValidClick then FIsValidClick := False; end else FLastMouseActivePoint := PointF(X, Y); inherited; end; procedure TipControl.MouseUp(AButton: TMouseButton; AShift: TShiftState; X, Y: Single); var LInvalidPressed: Boolean; begin FLastMouseActivePoint := PointF(X, Y); LInvalidPressed := not CheckHasValidClick; if LInvalidPressed then FIsValidClick := False; FIsMouseDown := False; inherited; end;

    Made sample here: https://github.com/viniciusfbb/skia4delphi/issues/12#issuecomment-933528854 Result:
  6. @Kazantsev Alexey Truth! It didn't cross my mind to use compile time messages. I took the test and confirmed the suspicion. MACOS is defined in OSXARM64. Docwiki is wrong. Issue reported.
  7. According to the Alexandria docwiki, the new OSXARM64 platform is defined for OSX directive but not defined for MACOS directive, which doesn't make sense since MACOS directive has always been defined for OSX and iOS. Unfortunately I don't have any mac arm to confirm. Can anyone confirm this?

    Skia4Delphi

    We are very pleased to announce the 2.0 release of the Skia4Delphi project. The library was almost completely rewritten, bringing many new features such as visual components (VCL/FMX), easy installation, easy configuration, miscellaneous error handling, and much more. Now it also has many more features as well as more examples. See main changes: v2.0.0 Added support for Delphi 11 Added support for OSX ARM 64-bit Added Setup (friendly install) Added IDE plugin to enable the skia in your project: replacing manual changes in project settings, deployment and dlls that were needed before. Now it's automatic, just right click on your project inside the IDE then "Enable Skia" Built-in by default the "icudtl.dat" file in dll Added the controls TSkLottieAnimation, TSkPaintBox and TSkSvg Added SkParagraph (multiple styles in text) Added support for Telegram stickers (using TSkLottieAnimation) Added error handling in sensitive methods Added the source of our website: https://skia4delphi.org Library rewritted Improved the integration with apple's MetalKit Improved library usage, like replacing SkStream to TStream Fixed AccessViolation using TStream Fixed issue with transparent bitmap in Vcl sample Fixed minor issues Explained Svg limitations in documentation We are now using the latest inactive milestone release of Skia (M88), because the others are updated frequently. Deprecated non-windows platforms in Delphi 10.3 Rio or older Homepage: skia4delphi.org GitHub: https://github.com/viniciusfbb/skia4delphi A liittle preview Setup Just download the Skia4Delphi_2.0.0_Setup.exe attached in Releases page.

    Skia4Delphi

    I didn't really investigate enough, I just noticed that more complex SVGs converted by Adobe programs weren't being read correctly. I reported this issue to skia and sent two examples of .eps files converted to SVG by adobe and another converter, where adobe's SVG is not rendered and other converters' SVG is rendered. Examples are attached. incompatible_svgs.zip

    Skia4Delphi

    @Rollo62 @dwrbudr @RDP1974 @Edwin Yip @Kas Ob. @hsauro I finally released version 1.1 which has been extensively tested on all platforms, which includes a complete demo project, demonstrating how to render svg files, lottie files and more, as well as fixing the issues with backwards compatibility, at the moment the library works on version XE6+ VCL or FMX. Skia's SVG module is still in the experimental phase, even though it works extremely well with most SVG files. Some bugs we detected in Skia's SVG module will be reported later today, however, some issues I'll expose here so you can help the community: Apparently, there is a format incompatibility - vectorized files exported as SVG by Adobe programs are not supported by Skia, however, if you use other online converters (like cloudconvert.com) to convert the .eps or the .ai to svg, it will probably works perfectly. In macOS depending on the language, the decimal separator is not dot (.), ie the conversion from string to float happens wrong depending on the macOS default system language Remarks: These errors are only in relation to the SVG module, which is still in the experimental phase, in addition, Skia is a robust and stable library; If the SVG file works on one platform, it will work the same on all. Changelog Added FMX sample (working from delphi XE6 and above, with platforms Win32, Win64, OSX64, iOS64, Android32, Android64); Added VCL sample (working from delphi XE6 and above); Added pre-built binaries of skia to repository, to facilitate implementation and to serve the samples; Updated skia to version 0.29.0; Added icudtl.dat file to windows platform; Fixed text shaping with RTL language; Fixed compilation in iOS; Fixed backwards compatibility with delphi XE6 above; About samples The samples already have the binaries configured. They are ready to Run.
