Today I'm getting crazy with Delphi Refactor > Rename Field (CTRL + SHIFT + E). Also starting a new IDE with a dummy project of only one variable the rename field get me the error: I don't know because message is in Italian language, but refactor is completly unusable. It notice that interface {B53A87B3-C809-4390-9BE2-6F1C168CF41D} is not registered. Athens 12.2 Patch 2. Any idea about that ?

THANKS, I missed this feature ! Now all works fine 🙂 #ITA: grazie mi hai salvato ore ed ore di pena nel dover reinstallare tutto da zero!.

How to register a TLB ? I'm used with regsvr32 DLL file but in this case Borland.Studio.Interop.dll don't is compatibile with regsvr32.

Ok but probably other things will go wrong with that. Seems that Borland.Studio.Interop interfaces are missing. There is a way to register them again without to reinstall the IDE ?

Hi all. There is a way to modify Bitmap contents (actually create content) of a DelphiFMX Image.Bitmap to add a text ? I've tried: bitmap = self.DIOImage.Bitmap bitmap.Width = int(self.DIOImage.Width) bitmap.Height = int(self.DIOImage.Height) bitmap.Clear(0xFF000000) canvas = bitmap.Canvas r = RectF(8 + 15, 10, bitmap.Width - 8, bitmap.Height - 10) ??? canvas.FillText(r, 'Hello World', False, 100, 0, 0, 0) ??? But the image remains EMPTY and doesn't show anything...

Seems that Canvas object is not usable in DelphiFMX. c.BeginScene() does not works also passing (None, 0) or any other combination: import delphifmx as fmx img = fmx.Image(None) bmp = img.Bitmap print(f'Initial Image Width : {img.Width}') print(f'Initial Image Height : {img.Height}') print(f'Initial Image.Bitmap Width : {img.Bitmap.Width}') print(f'Initial Image.Bitmap Height : {img.Bitmap.Height}') bmp.Width = 200 bmp.Height = 200 img.Width = bmp.Width img.Height = bmp.Height print(f'Actual Image Width : {img.Width}') print(f'Actual Image Height : {img.Height}') print(f'Actual Image.Bitmap Width : {img.Bitmap.Width}') print(f'Actual Image.Bitmap Height : {img.Bitmap.Height}') c = bmp.Canvas print(f'Canvas Width : {c.Width}') print(f'Canvas Height : {c.Height}') r = fmx.RectF(0.0, 0.0, 100.0, 100.0) c.BeginScene(None, 0) try: pass #c.FillText(r, 'hello', True, 1, [], 'Center', 'Center') finally: c.EndScene() *** Remote Interpreter Reinitialized *** Initial Image Width : 50.0 Initial Image Height : 50.0 Initial Image.Bitmap Width : 0 Initial Image.Bitmap Height : 0 Actual Image Width : 200.0 Actual Image Height : 200.0 Actual Image.Bitmap Width : 200 Actual Image.Bitmap Height : 200 Canvas Width : 200 Canvas Height : 200 Traceback (most recent call last): File "D:\x\develop\qem\cnc_api_client_core_1\python\api_client_fmx_demo\test-001.py", line 30, in <module> c.BeginScene(None, 0) TypeError: "BeginScene" called with invalid arguments.

So far, when I wanted to add a new UI component to DelphiVCL, I always started from DelphiVCL source, added the new unit with classes and types, and created a “clone” of the package with the new functionality using that instead of DelphiVCL. It works but I would like to “not touch” the original version of DelphiVCL installed by PyPi but only create an extensive module (pyd) with only the new UI controls. At this point I don't know if this can be done. I still understand little about P4D but it seems to me that each new module requires a PyEngine which loads the python DLL and this is already instantiated by DelphiVCL and if I create a new package with my new module and controls I assume there will be conflicts. Is this a viable way ? Is there any way to reuse the egine already created by original DelphiVCL to use it in my custom PYD ? I thank in advance those who will help me to dispel these doubts.

Hi all, I'm trying to convert an old DelphiVCL (python) application to DelphiFMX and I was not able to define the form title icon image. In Project Options I've set Icon resource, as I made with DelphiVCL version: But during the python run the icon is not visible: I've searched for Icon property in TForm and TApplication but not available. There is a way ? Thank you in advance for any suggestion. Best regards.

Hello everyone, after years I decided to migrate a big project from Sydney 10.4.2 to Athens 12.2 latest version. Most things went smoothly, others required some work in the code but it works fine. I am left with one problem and one solution to find. In Sydney the default font used was “Tahoma 8” and the entire software was reliant on it and its features, which must often take advantage of every available pixel in the screen. Now when I create a new form or frame or add an object, I always end up with “Segoe UI 9” as the default font which returns text that is wider in width and breaks the continuity of the existing form/frame hundreds for me. How can I make sure that the old “Tahoma 8” is used as the default font during development and execution ? Many controls have multiple fonts and it is nerve-wracking to have to go searching for each “Font” property within them to change them by hand each time. Thank you.

Woe is me, I had modified the global DefaultFont var but not the Application.DefaultFont.Name var. Thanks for help !!!

Our applications run on embedded panel pc which have fixed inches size and are all FullHD, so HDPI is not used. I've tried also to change DefaultFont.Name := 'Tahoma' of VCL.Graphics in first steps of DPR but nothing changed.

Try to check the stack of called methods, someone try to use a wrong pointer value or object reference.

My 2 cents. I have been working with Delphi since the first version, that is, forever. It is my main development tool and one thing I have learned over the years. Whatever version I patch or whatever it is, I first install it on a VM. I never use third-party packages that don't start from source (no pre-compiled BPLs). I install all packages from source (with obvious modifications if they give problems). When everything works and I can work a few hours on the VM without any hiccups, then I uninstall the package from the working PC, clean up all directories and files from the previous installation that were not removed during uninstall, and repeat the operations done on the VM. It's a lot of work but I don't immediately switch to a new version when it appears. I wait for the inevitable patched versions to come out so I don't waste hours and hours of work. With these operations the bugs and snags are kept to a minimum and you can work.

The best Editor component, better than native Delphi IDE editor (IMO).

I have been using Delphi for our software since version 1.0 and the latest project exceeds 22 million lines of code, but I have never felt the need to have the Enterprise or Architect version. Software products are tied to hardware equipment and 99% of the time they are free so keeping a subscription alive for Enterprise/Architect would become too costly for a small company. A missed opportunity in my case, I am continuing with the Pro version. In any case, Delphi remains and will remain my favorite development tool.

I don't know if it is a false positive, the fact is that I was unable in any way to download the file because of our server antivirus actions.

Something goes wrong with either links. Virustotal notice a malware in the home page: https://www.virustotal.com/gui/url/ed9d2c0aac2e802dc498bc8fc7e8eb6102005a3f87606340d6837a7969846413?nocache=1 When I try to download the file, as in your previous image, Free Download manager refuse to start, then automatically begin the normal chrome download but a 99% downloading stops with message "file not available on the net". Changing https:// to http:// in https://asphyre.net/files/Afterwarp-SDK-v300.7z with Download manager the download start but close to end of the download the HTTP 403 error appears. At this point I've asked to VirusTotal to refresh the virus check of Afterwarp-SDK-v3007.7z submitting the download link and it notice two positive for "asphyre.net/files/Afterwarp-SDK-v300.7z contiene malware of type Cloud Virus": https://www.virustotal.com/gui/url/7e3fa21609ded7e62223028b875f7eb8a497e08550d574c49430cd53896bd222?nocache=1

Hi all. I've to convert a Builder C++ code to Delphi which uses bitfiels in union and I don't know where to start and if it is possible: // define QCL data types typedef short QCL_WORD; typedef union { QCL_WORD data; struct { QCL_WORD alarm_state :1; // bus flags: alarm state QCL_WORD alignment_state :1; // bus flags: alignment state QCL_WORD inversion_wait :1; // bus flags: external synchronism - inversion wait QCL_WORD out_of_min_bound :1; // bus flags: column position is out of minimum boundaries QCL_WORD out_of_max_bound :1; // bus flags: column position is out of maximum boundaries QCL_WORD below_safety_height :1; // bus flags: column position is below safety height QCL_WORD in_working_pos :1; // bus flags: column position is in working position QCL_WORD locking_latch_state :1; // bus flags: column position in locking latch state QCL_WORD battery_warning :1; // bus flags: column in battery warning QCL_WORD battery_alarm :1; // bus flags: column in battery alarm QCL_WORD evr_state :1; // bus flags: column EVR state QCL_WORD load_weight_zone :2; // bus flags: column in load weight zone QCL_WORD column_is_consistent :1; // bus flags: column in load weight zone QCL_WORD lift_set_acquire_req :1; // bus flags: columns lift set acquire request QCL_WORD movement_mode_absolute :1; // bus flags: column has movement mode absolute } fields; } t_bus_flags_w4; Thanks in advance for any suggestion.

PERFECT is just what I need....

I found an oddity in the "state" field of the OnCustomDrawItem event. Basically instead of reporting the states of the VCL control passed by the related event all possible states are passed there: function CustomDrawStateToPython(const ACustomDrawState: TCustomDrawState): PPyObject; procedure Append(const AList: PPyObject; const AString: string); var LItem: PPyObject; begin with GetPythonEngine do begin LItem := PyUnicodeFromString(AString); PyList_Append(AList, LItem); Py_XDecRef(LItem); end; end; var LCompType: PTypeInfo; LMin: integer; LMax: integer; LState: integer; begin Result := GetPythonEngine().PyList_New(0); LCompType := GetTypeData(TypeInfo(TCustomDrawState)).CompType^; LMin := LCompType^.TypeData^.MinValue; LMax := LCompType^.TypeData^.MaxValue; for LState := LMin to LMax do Append(Result, GetEnumName(LCompType, LState)); // <-- all enums are always set to state python attribute end; In my TreeView, when a node is selected, I've to change to white the font color otherwise text is hard to be sight: Either I completely misunderstood the functionality of that function or there was an oversight. Unfortunately Vcl.ComCtrls TCustomDrawItem is defined as a set with direct enumerators in the set so I didn't find a direct method to do: if CAST_TO_ENUM(LState) in TCustomDrawState then but with a forcing and a pointer you still get something working: function CustomDrawStateToPython(const ACustomDrawState: TCustomDrawState): PPyObject; procedure Append(const AList: PPyObject; const AString: string); var LItem: PPyObject; begin with GetPythonEngine do begin LItem := PyUnicodeFromString(AString); PyList_Append(AList, LItem); Py_XDecRef(LItem); end; end; function IsBitSet(Index: Integer; State: TCustomDrawState): Boolean; var P: PByte; begin if (Index < 0) or (Index >= SizeOf(TCustomDrawState) * 8) then Exit(False); P := @State; Result := (P^ and (1 shl Index)) <> 0; end; var LCompType: PTypeInfo; LMin: integer; LMax: integer; LState: integer; begin Result := GetPythonEngine().PyList_New(0); LCompType := GetTypeData(TypeInfo(TCustomDrawState)).CompType^; LMin := LCompType^.TypeData^.MinValue; LMax := LCompType^.TypeData^.MaxValue; for LState := LMin to LMax do begin if IsBitSet(LState, ACustomDrawState) then Append(Result, GetEnumName(LCompType, LState)); end; end; I'm not so smart in these things so if some Delphi guru has a better solution I'm ready to fix the code. Best regards.

New commit fixes the issue and works perfectly.

Incredible work. Just one question. I have tried several times to install the 5.0.0 Beta version via the Upgrade Check function getting always getting the error "File download failed.

I need some help from Python + DelphiVCL guru. Some time ago I've made a new DelphiVCL control to use VTK with Python + VCL + VTK. To do that I've modified the Embarcadero's DelphiVCL package to add new control, called new library as cnc_vision_vcl to not override already installad DelphiVCL library and all worked fine. But I don't want to have a custom DelphiVCL and so I've tried to move the component in a delphivcl_ext project and at now same code does not work. What I've to in native Delphivcl code (which works) Create a clone of DelphiVCL projects as cnc_vision_vcl. Created new component WrapExtVTK.pas (attached). Modified source\vcl\WrapVclControls to import new unit: uses WrapDelphiTypes, WrapDelphiClasses, WrapDelphiWindows, WrapDelphiDataBind, WrapActions, WrapVclImgList, WrapVclControls, WrapVclGraphics, WrapVclForms, WrapVclActnList, WrapVclMenus, WrapVclStdCtrls, WrapVclComCtrls, WrapVclExtCtrls, WrapVclButtons, WrapVclGrids, WrapVclSamplesSpin, WrapVclWinXCtrls, WrapVclThemes, WrapVclDialogs, WrapVclMedia, WrapExtVTK; // <--- new unit Compiled and used new cnc_vision_vcl.pyd file In the cnc_vision_vcl a zip with working test All work fine but I want to move component in an "ext"tra package to leave untouched original delphivcl, so I've created a clean project which add almost the same code but when I try to create the VTKPanel object I obtains: self.vtk_panel = VTKPanel(self) ^^^^^^^^^^^^^^ AttributeError: Owner receives only Delphi objects In next chat the zip of entire project because I've reached post limits. WrapExtVTK.pas cnc_vision_vcl.zip
