![]() 4 Applications software produced with Free Pascal.3.1 Version 2.3.x (development version).The visual parts of the Delphi libraries (the VCL) and the creation of a visual IDE and RAD are part of a separate project, Lazarus. FPC supports multiple architectures and notations in the internal assembler. Like Turbo Pascal and Delphi, Free Pascal has excellent support for integration of assembly language in the Pascal code. This IDE deteriorated for some time because of a missing maintainer, but in a common effort in the second half of 2005 and the first months of 2006, most major bugs were fixed and the IDE became release-worthy again. To avoid this confusion, at the end of 1997 the name of the project was changed into Free Pascal Compiler (FPC).įree Pascal comes with a text mode IDE resembling Turbo Pascal's IDE. Writing "Compiler" with K is uncommon in German. ![]() FPK Pascal never meant "Free Pascal Kompiler". The 32/64-bit architecture and multi-operating system compiler implements the Pascal dialects (Turbo Pascal and Delphi) as well as some MacPascal constructs, and is available forįree Pascal used to be known as FPK Pascal, since FPK are the initials of the author, Florian Paul Klämpfl. Users who will compromise its status may be blocked.įree Pascal (or FPK Pascal or FPC) is a free, portable, open source, Pascal and Object Pascal compiler. This article is featured it's one of the best articles at the Borland Pascal Wiki. Procedure TForm1.This page uses Creative Commons Licensed content from Wikipedia ( view authors). Procedure TForm1.Button1Click(Sender: TObject) Į := TEdit.Create(Self) // Create new TEdit controlĮ.Parent := Self // Place control onto the form Procedure EditKeyDown(Sender: TObject var Key: Word Shift: TShiftState) So, you can not assign to the event any procedure but only class method with parameters provided in the type declaration.Ĭlasses, SysUtils, Forms, Controls, Dialogs, StdCtrls Where of Object means that your event handler must be a class method. For example, OnKeyDown event have a type TKeyEvent = procedure(Sender: TObject var Key: Word Shift: TShiftState) of Object ShowMessage(Format('%s %d', )) // Right, %s means string value and %d means decimal value, see help about Format functionĮvents is a procedural variables so they have its own types. ShowMessage(a, ' ' ,i) // Wrong, ShowMessage takes only one string parameter Procedure Demo_Procedure(i: integer a: String) // Right, use semicolon as parameters delimiter There are errors in your code: procedure Demo_Procedure(i: integer, a: String) // Wrong Now, researching around i found out that some people that put an before calling the method, the only difference is that this time instead of saying "untyped" it says that it got " procedure variable type of procedure(AnsiString,LongInt) of object" and that it was expecting the same as before ( procedure(TObject,var> Word,Tshift.etc)Ĭan anyone help me out here? I really am lost so any help would be greatly appreciated. If i do it like this: Demo_Procedures(5, 'Hi'), it says:Įrror: Incompatible types: got "untyped" expected "procedure variable type of procedure(TObject,var Word,TShiftState) of object Register>" Im getting different errors depending on how i call up my procedure. Now, for my dynamically created elements im trying to set the "OnKeyDow" event to run my new procedure (this is what i dont A- know if its possible to do or B- how to do it) NewlyButton.OnClick:= Demo_Procedure(5, 'Hi') ![]() procedure Demo_Procedure(i: integer, a: String) Then i proceeded to "develop" my procedure underneath the "implementation" part of the Form. I added a new procedure in my app (this is for explaining purposes only): procedure Demo_Procedure(i: integer, a: String) Thing is, i need to execute some procedures on the newly created elements. I have an application which dynamically creates TextBoxes (TextEdits in this case) and adds them to a panel for displaying. I hope this question is a fair one because, honestly, i dont know how to figure this out. I've ran into this problem and, after trying for like hours on my own and looking for similar cases on the internet, i have not found anything. Im relatively new to Pascal and, though i have a fair understanding of the language, there's still some stuff i cant figure out how to implement. ![]()
