Re: [Fxruby-users] Usage FXList : makeItemVisible

[SIMOKAWA h. <h-s...@aa...>]

Hello all.
Thanks for Dalibor Sramek and meinrad recheis.

I have confirmed that the 'makeItemVisible' works after 'show'.

Another Question:
The 'makeItemVisible' is not working just after 'clearItems'.
A 'create' is need before 'makeItemVisible'.
But when not just after, the 'create' is needless.

Below is my code.
If you delete line#2, btnV9 is not work.
If you delete line#1 and #2, btnV9 is work after pushing btnUp.

Thanks for the help in advance
