Press [Update Local File Cache] in SDK Manager after libgtk-3-dev installed.

type TForm1 = class(TForm) ListView1: TListView; procedure FormCreate(Sender: TObject); procedure ListView1UpdateObjects(const Sender: TObject; const AItem: TListViewItem); procedure FormDestroy(Sender: TObject); private FCustomItem : TListViewItem; FBitmap : TBitmap; public { Public declarations } end; var Form1: TForm1; implementation {$R *.fmx} procedure TForm1.FormCreate(Sender: TObject); begin for var i := 1 to 25 do ListView1.Items.Add.Text := Format('item #%u', [i]); FCustomItem := ListView1.Items[4]; FCustomItem.Text := 'Custom Background Item'; var c := TAlphaColorRec.Orangered; TAlphaColorRec(c).A := 64; FBitmap := TBitmap.Create(8, 8); FBitmap.Clear(c); end; procedure TForm1.FormDestroy(Sender: TObject); begin FBitmap.Free; end; procedure TForm1.ListView1UpdateObjects(const Sender: TObject; const AItem: TListViewItem); begin if AItem = FCustomItem then begin var Bkgnd := TListItemImage.Create(nil); Bkgnd.ScalingMode := TImageScalingMode.Stretch; Bkgnd.OwnsBitmap := False; Bkgnd.Bitmap := FBitmap; AItem.View.Insert(0, Bkgnd); end; end; custom_bkgnd_item.zip

program Project1; {$APPTYPE CONSOLE} uses System.Rtti; type TvatIndividual = record DocumentNumber: string; TurnoverDate: TDate; PaymentDate: TDate; DocumentType: string; Year: integer; TurnoverDescription: string; TurnoverAmount: Currency; end; begin for var f in TRttiContext.Create.GetType(TypeInfo(TvatIndividual)).GetFields do WriteLn(f.ToString); ReadLn; end.

You need to specify parameters --libpath and --syslibroot. Values can find in SDK Manager.

You can register your own IFMXSystemFontService.

Use ampersand operator, Luke. program Project2; {$APPTYPE CONSOLE} uses System.TypInfo; {$SCOPEDENUMS ON} type TEnums = (&TRY, &SHR, &XOR, &IS, &AS); begin WriteLn(GetEnumName(TypeInfo(TEnums), Ord(TEnums.SHR))); WriteLn(GetEnumValue(TypeInfo(TEnums), 'shr')); ReadLn; end. Output: SHR 1

You can use SysGetMem, SysReallocMem, SysFreeMem.

Sorry for dirty adaptation spritz_bench.zip

Two cent about compilers performance by the example of spritz-c stream cipher implementation: 1. Delphi 11, Windows x86_64 (classic compiler), release 2. Delphi 11, Linux x86_64 (nextgen, LLVM based compiler), release 3. FreePascal 3.3.1, Linux x86_64, release

Try to check file version of your delphide280.bpl (or just run Delphi only, not RAD Studio)

Some about build numbers: https://blogs.embarcadero.com/rad-studio-11-2-alexandria-patch-1-available/#Final_Note_The_Patch_is_Listed_in_the_About_Box

You don't need mac to compile units. Just use command line compiler to compile this unit: unit def; interface implementation {$if defined(MACOS)} {$message hint 'MACOS defined'} {$endif} end.

The same example on 10.4.2: 1770kb, 1279kb, 456kb

For XE2 you need explicitly rebuild the three files (for latest versons need some more rtl files be rebuilded): system.pas (with key -Y) system.sysutils.pas (with key -V-) system.variants.pas (with key -V-) (search path should include rtl sources) When project building seach path should include your own custom rtl dcus, and rtl sources after it.

library rtltest; //{$weaklinkrtti on} uses system.classes; begin TMemoryStream.Create.Free; end. Delphi XE2, x86_64, Release: default - 547840 bytes + weaklinkrtti on - 505344 bytes + custom rtl build with minimal rtti - 256000 bytes

The error is not in the implementation of the custom initializer. A custom initializer is available for the “TRec” type, but an initialization error is in the “TData” type, which does not have a custom initializer, but has a field of a managed type. In the code example, you can replace the custom initializer with any other custom management operator (finalizer, assign), and you will get the same error.

5.5. It also makes sense to change the clHighlightText color for better look of some IDE parts (ObjectInspector, Options Dialogs, New Items dialog).

1. Run any resource editor (ResourceHacker, for example) and open ModernTheme260.bpl 2. Extract resource "WIN10IDE_LIGHT" to file *.vsf 3. Open saved file in the Bitmap Style Designer ($(BDSBIN)\BitmapStyleDesigner.exe) 4. In the tree-structure "Objects" find node "SysColors" and item "clHighlight" 5. Change the "clHighlight" to you prefered color 6. Save modified style and close Style Designer 7. Using resource editor replace resource "WIN10IDE_LIGHT" in ModernTheme260.bpl by the modified style file. p.s. This issue planed to fix soon.

Export is not required, it's the same theme. Changed the drawing method.

Your can extract WIN10IDE_LIGHT resource from ModernTheme260.bpl, change SysColors.clHighlight by the BitmapStyleDesigner.exe and replace the style resource. https://i.imgur.com/lrod4rO.png But it will affects on the some other UI elements, M main menu items, for example. https://i.imgur.com/sTV5O83.png

Set "Dark" IDE Theme.
