Lazarus code with Free Pascal does not work properly

[Fanie van der Walt]

I am writing a program using Lazarus. The scroll bars do not work with a Memo component, or with a StringGrid component. The main Menu does not work.

What do you mean? Could you kindly post a screenshot of the issue?

Hi Bilal,

The attached photo shows the corrupted menus in Lazarus - all the rest
are also like that.
Unfortunately I can not show you the form in my program, containing a
StringGrid, with a scroll bar which does not scroll the contents,
because I have gone back to Ubuntu 10.10.

I am afraid I must vote "negative" for Unity - I don't like it. I
dislike being communicated to in pictures, where menus with text are
much more efficient! Sorry.

Thank you for your attention.

Fanie van der Walt.

Hi Bilal,

I had the same problem in my Lazarus application. Finally, I solved it.

You have to set LIBOVERLAY_SCROLLBAR to 0 directly in your lazarus app. This has to be done before widget set is inicialized. So I created a unit called uScrollBars.pas and add it into initialization section.

More at:

http://cqrlog.svn.sourceforge.net/viewvc/cqrlog/branches/cqrlog_1.2.2/src/uScrollBars.pas?revision=339&view=markup

You must add this unit into your project file as a first unit (or the second if you are using threads in your app).

Hi Petr,

Thank you. I will try it - next time I install Ubuntu with Unity.

Greetings,
