trying to get shapefiles to display on a TSphere Component in BOLT.pas(UNIT 1/Form1) from GISEngine.pas
i tried this
function TGISEngine.RenderShp: boolean; begin GISobj.Viewport3D1.Parent := Earth; end;but that doesnt do anything here is the full unit
unit GISEngine; //thank you programmerdelphi2k for helping //This unit Displays Shapefiles onto a 3D Globe interface uses System.SysUtils, System.Classes, FMX.Viewport3D, FMX.Objects3D, System.IOUtils, System.Generics.Collections, BOLT; type TGISFilesnamesSHP = TArray<string>; TGISEngine = class private FFilenames : TList<string>; Viewport3D1: TViewport3D; Earth: TSphere; function GetFilename(const i: integer): string; public constructor Create; overload; constructor Create(const AFilenames: TGISFilesnamesSHP); overload; destructor Destroy; override; procedure AddFilenames(const AFilenames: TGISFilesnamesSHP); procedure ClearFilenames; function CountFilenames: integer; function RenderShp: boolean; property Filename[const i: integer]: string read GetFilename; property Filenames: TList<string> read FFilenames; function VerifyIfAllFilesSHPExists(out AErrors: TGISFilesnamesSHP): boolean; function LoadFilenames: boolean; property GISViewport3D: TViewport3D read Viewport3D1 write Viewport3D1; property GISEarth: TSphere read Earth write Earth; end; var GISobj : TGISEngine; Form1: TForm1; implementation { TGISEngine } constructor TGISEngine.Create; begin Viewport3D1 := TViewport3D.Create(nil); Earth := TSphere.Create(nil); FFilenames := TList<string>.Create; end; constructor TGISEngine.Create(const AFilenames: TGISFilesnamesSHP); begin Create; AddFilenames(AFilenames); end; destructor TGISEngine.Destroy; begin FFilenames.Free; Earth.Free; Viewport3D1.Free; inherited; end; function TGISEngine.GetFilename(const i: integer): string; begin result := ''; if (i > -1) and (i < FFilenames.Count) then result := FFilenames.Items[i]; end; procedure TGISEngine.ClearFilenames; begin FFilenames.Clear; end; function TGISEngine.CountFilenames: integer; begin result := FFilenames.Count; end; procedure TGISEngine.AddFilenames(const AFilenames: TGISFilesnamesSHP); var F: string; begin if (Length(AFilenames) > 0 ) then for F in AFilenames do if not FFilenames.Contains(F) then FFilenames.Add(F); end; function TGISEngine.VerifyIfAllFilesSHPExists(out AErrors: TGISFilesnamesSHP): boolean; var F: string; begin result := false; if (FFilenames.Count = 0) then begin AErrors := ['Filenames list is empty']; exit; end; for F in FFilenames do if not FileExists(F) then AErrors := AErrors + [F + ', dont exists!']; end; function TGISEngine.LoadFilenames: boolean; var F: string; begin result := false; if (FFilenames.Count > 0) then begin for F in Filenames do GISobj.AddFilenames(['tl_2021_01001_roads.shp','world-administrative-boundaries.shp']); end; end; function TGISEngine.RenderShp: boolean; begin GISobj.Viewport3D1.Parent := Earth; end; initialization GISobj := TGISEngine.Create; finalization GISobj.Free; end.

Im trying to communicate with a component in Unit1 from Unit4 but when i click on the button i get a access violation error how can i resolve this
procedure TForm4.Button1Click(Sender: TObject); var Label21: Tlabel; Button1: Boolean; ProgressBar1 : TProgressBar; begin // ProgressBar1.Visible := True; //Component is in Unit1 (Bolt) end;

Do you want to add the selected from ComboEdit1 to the dropdown of ComboEdit2?
Hook Combo1Edit.OnSelect
procedure TForm4.ComboEdit1OnSelect(Sender: TObject); begin ComboEdit2.Items.Add(ComboEdit1.Text); end;
This event is called when an item is selected from the dropped down list of ComboEdit1.
Naturally, you need to add code to see if the item has already been added before you add it.@Lars Fosdal that doesnt work
-
Im trying make a procedure that when you select an item from ComboEdit1 (it will officially list items from a ftp site) but for a test im
trying to list the same item from ComboEdit1 to ComboEdit2
procedure TForm4.ComboEdit1Click(Sender: TObject); begin end;i have tried %s like ComboEdit2.Items.Add('%S'); but that doesnt work
here is the list items for ComboEdit1 and i havent been able to find code examples

@programmerdelphi2k also do you know how to set the TCalloutpanel visibilaty to true when you click on the earth
im trying to do this
procedure TForm1.Button22Click(Sender: TObject); var Marker : TCalloutPanel; Coord: TLabel; MarkerBool: Boolean; begin if MarkerBool then begin Marker := TCalloutPanel.Create(Self); Marker.Width := 209; Marker.Height := 41; Marker.RotationAngle := 180; Marker.Visible := False; Marker.Parent := Self; Coord := TLabel.Create(Self); Coord.Width := 120; Coord.Visible := False; Coord.Parent := Self; Coord.Height:= 17; Coord.Text := '00.00000 -00.00000'; end else begin Earth.OnClick := Marker.Visible:=True; //<--Code Doesnt work keep getting incompatible types TNotiftEvent and procedure untyped pointer or untyped parameter -
Im trying to get TCalloutPanel to follow the mouse pointer but i cant find any code examples on this here is the code i have so far
procedure TForm1.Button22Click(Sender: TObject); var Marker : TCalloutPanel; begin // Marker := TCalloutPanel.Create(Self); Marker.Width := 209; Marker.Height := 41; Marker.RotationAngle := 180; Marker.Visible := True; Marker.Parent := Self; end; -
im trying to make a button to show a tooltip style popup that hovers over a mouse pointer inside viewport3D using a bitmap image to show actual map coordinates when you click on a area it will show that area in google maps in the viewport how can i do this?
here is a example
-
Im trying to make a
starmap skybox in the viewport 3d background similar to what google earth does

On 12/5/2022 at 8:05 AM, programmerdelphi2k said:change " for var in AFilenames do" by "for var F in AFilenames do"
@programmerdelphi2k that still wont work same error
-
Keep getting Expected and identifier but received VAR same for IN and Contains
procedure TGISEngine.AddFilenames(const AFilenames: TGISFilesnamesSHP); begin if (Length(AFilenames) > 0 ) then begin for var in AFilenames do if not FFilenames.Contains(F) then FFilenames.Add(F); end; end; -
@ptlycldy im trying download the GRIB2 Data and then display the data onto the sphere something like this

@programmerdelphi2k i keep getting Type BOLT (which is my unit1 or TForm1) is not yet completely defined and i have been unable to resolve the error and yes i have looked at the docwiki
unit GISEngine; //This unit Displays Shapefiles onto a 3D Globe interface uses System.SysUtils, System.Classes, BOLT, FMX.Viewport3D; type BOLT = class(BOLT) Viewport3D1:TViewport3D; procedure VP3DGISEngine(Sender: TObject); private public end; var Form1 : TForm1; implementation end. -
I have a unit called BOLT and i would like to use the viewport component from that unit to my GISEngine unit how can i do this?
unit GISEngine; interface uses System.SysUtils, System.Classes, BOLT, FMX.Viewport3D; implementation procedure TForm1.Viewport3D1(Sender: TObject); begin end; end.Error GISEngine does not contain a member named Viewport3D1

How can i make a pas file to visualize GRIB2 Files i cant find any references anywhere
-
and im still getting that annoying issue when i cant close out of the main application after i clicked on the button in my popup window
-
@Ramy Lebeau for some reason im still not able to hear any audio
-
how can i draw a gradient paintbrush with a draw over animation on a sphere
-
-
now i get this and also when i click on the design tab i keep getting a error saying container form not set and i changed the name from ignore the first error i got it fixed but im still getting the second error
//second error line LIdx := AAngle div 15.0;
-
@Rollo62 i put the function under public still wont work
private { Private declarations } public { Public declarations } function TForm7.KnobLabelStationAngle(const AAngle : Single) : String; overload; function TForm7.KnobLabelFreqAngle(const AAngle : Single ) : Single; overload; end;procedure TForm7.KnobClick(Sender: TObject); begin //Knob Knob.RotationAngle := Knob.RotationAngle - 15.0; Rectangle4.RotationAngle := Knob.RotationAngle - 15.0; Label2.Text := Format ('%s', [KnobLabelStationAngle(Knob.RotationAngle), KnobLabelFreqAngle(Knob.RotationAngle) ] ); end; function TForm7.KnobLabelStationAngle(const AAngle : Single) : String; const CStationLabel : array[0..24-1] of String = ('KEC61', 'WXK30'); var LIdx : Integer; begin LIdx := AAngle div 15.0; Result := CStationLabel[LIdx]; end; function TForm7.KnobLabelFreqAngle(const AAngle : Single ) : Single; begin Result := (AAngle / 162.550 * 162.525 * 162.500 * 162.400 * 162.475) end;
-
@Rollo62 sorry if this question sounds basic but i cant figure out how to fix this error TForm7 does not contain a member named KnobLabelStationAngle i have put the function line under the procedure and in public/private nothing worked
Shapefiles not projecting to TSphere
in FMX

@programmerdelphi2k is f needed in
MyDataFromFileSHP.Add(F,'tl_2021_01001_roads.shp', 'world-administrative-boundaries.shp');i tried overload but that didnt work
