 |

allo,
code sample :-
constructor TScrollBoxEx.Create(AOwner: TComponent);
begin
inherited Create(AOwner);
BorderStyle := bsNone;
......
end;
now the compiler gave an error like:
Incompatible types:'forms.TBorderStyle' and 'scrollboxex.TBorder'
what can i do to overcome that.
ciao
daniel

How is "BorderStyle" defined? BorderStyle: TBorder; ?
Also for your last post, you could maybe try to use
BorderStyle: Forms.TBorderStyle;
I have only seen problems like this once before when some friends were
messing round with some COM objects. In other programming languages I
would say you were missing the wrong namespace... but Delphi does not
really use namespaces?

No, but qualifying identifiers with unit names serves much the same
purpose.

allo nicolai,
if you re-look at my code excerpt,
| Quote: | 1 > constructor TScrollBoxEx.Create(AOwner: TComponent);
2> begin
3> inherited Create(AOwner);
4> BorderStyle := bsNone;
5> .....
6> end;
|
in 4 above, is the problem line pointed out by the compiler.
what I want is that any new object "ScrollBoxEx1 for example", created by
calling that constructor will have the borderStyle set to bsNone.
but that problem halted my work, so please help.
thanks.

The error tells you:
FIRST argument (BorderStyle) is of the type "forms.TBorderStyle".
SECOND argument (bsNone) is of the type "scrollboxex.TBorder".
"forms.TBorderStyle"<>"scrollboxex.TBorder".
This is like trying to assign an integer to a string.
I would think that in the ScrollBoxEx unit somewhere there was a
definition like
TBorder=(bsNone, bsDouble, bsSingle);
which makes the use of "bsNone" inside the scrollboxex creator point
to a TBorder type. Your scrollboxex probably have a property
property BorderStyle: TBorderStyle;
which is found in the forms unit, defined as
TFormBorderStyle = (bsNone, bsSingle, bsSizeable, bsDialog,
bsToolWindow,
bsSizeToolWin);
TBorderStyle = bsNone..bsSingle;
Even though your definition in your unit is excactly the same as this.
Even if your definition is just "TBorder=bsNone..bsSingle"... it will
give a conflict between the types.
To fix, I would suggest removing the TBorder definition unless it is
used elsewhere. Post code.
