[Lazarus] Dynamic creation of TTrackBar

[Duncan Parsons]

Not got Laz/fpc code near me, but my guess is that when you have a
TTrackBar on the form, the unit that it's housed in will be added to the
uses list, and if you delete it (provided no other referenced classes
are included) it may get removed.

Find which unit TTrackBar is declared in and add it to the relevant uses
clause by hand..

Does that help?

Subject: [Lazarus] Dynamic creation of TTrackBar

G'day all,

I'm currently using "Lazarus 0.9.29 r22679 FPC 2.2.5 i386-linux-gtk 2
(beta)".

On a form, I'm creating 30-40 instances of a TTrackBar dynamically. If,
at design time I have a TTrackBar on the form, this all goes swimingly.
If, however there is no TTrackBar on the form, when I run the
application I get "Class "TTrackBar" not found.".

I'm pretty sure I've created components dynamically before and not
bumped up against this. I *know* I'm doing something dumb, but it's late
and I just can't figure out what it is.

Can someone whack me with the clue bat please?

Regards,
Brad
