Hi,

I'm busy now for day's to find a way to make the form or an panel
larger than the screen size, this can be easly done by choosing the
screen size , but what happends with the form or panel which will
be out of the screen size?, it seems it's still there but you can't
reach it, so a scrollbar should be very usefull, so you don't have
to create an amount of panels or form (on the exact size of the screen
self i mean).
Does there is an way to build an form or panel wich you can reach over
the full length?, like putting an button on the right corner which contains
next or more.. e.t..

I'll hope there is some solution for this, because im writing some text
on the screen which are more rows than the current form or panel can
take.

thanks

You should have asked earlier ;)
You can use a ScrollBar and a panel to achieve it.

The application and the ScrollBar library are also attached.

Also, the best place to ask is in the questions forum, not on the samples one....

And of course, we all have learned a new bit with EREL's example...

I think that your question is for Basic4Android, so your post should be in the Android forum.
If it is for Badic4PPC, Gradientdrawable doesn't exist. You should create a bitmap with the gadient colors and set it to the panel.

Best regards.
