Title: Tips to ensure _TITLE works?
Post by: Dav on September 10, 2018, 11:33:09 am

I always had to add a small delay when using _TITLE to make sure it will work, and a delay works, but recently found out that these things will make _TITLE work when called without delay. 

#1) Loading an icon first makes _TITLE work instantly.
#2) Calling _SCREENMOVE _SCREENX, _SCREENY before calling _TITLE makes _TITLE work instantly.

Has anyone found anymore ways that can eliminate the delay needed with _TITLE?

You can wait until the screen exists. It is a delay, but one that only lasts as much as needed, no less, no more:

Code: QB64: [Select]

1. DO UNTIL _SCREENEXISTS: _LIMIT 30: LOOP

Clippy discovered that one back in the SDL days and it's the method I've used since. I didn't realize there were other ways to get it to work.

That works good too.  Thanks.
