custom component with different properties
«
on:
March 27, 2023, 01:20:37 am »
Hola,
is it possible to make a component that has certain properties in windows and not in macos?
and when loading the project in macos the error "property not found..." does not appear?
Would we have to modify the lfm every time?
thanks

you can simply put a dummy property in there.
in code you can use some compiler test to check for the OS being targeted and decide not to include code.
At least that way you won't have that problem.
This is why they make widget interfaces.

Code: Pascal
[Select]
[+]
[-]
program
Project1
;
type
TMyString
=
class
strict
private
FString
:
string
;
published
{$IFDEF MSWINDOWS}
property
MyString
:
string
read
FString
write
FString
;
{$ENDIF}
end
;
var
MyString
:
TMyString
;
begin
MyString
:
=
TMyString
.
Create
;
try
// the next line works exclusive under windows
// all other OS do not have the "MyString" property
MyString
.
MyString
:
=
'Some string'
;
finally
MyString
.
Free
;
end
;
end
.

and what happens when you move the project to MACos ?
The Lfm file still contains a property name that could of been set in the windows target.

I think one of the most practical solutions could be to move the properties from "published" to "public" with their conditionals and thus they would not be saved in the lfm.
