Re: [FTC b15pv11] DrawBackground

I discovered what the issue is. You are using BitDepth to create the Display object. In your example program you have BitDepth defined in your Window. If I set the BitDepth in the FormattedText control in the open even to 32 everything works as it should.

I'm not entirely sure what's going on. I'm updating an application that hasn't been updated since b15pv9 and I also just switched to RB 2008 r1.
I'm getting a nil object exception in pv11 when simply replacing the older components with the new one. The exact error is happening in FormattedText.drawBackground and g is nil after calling g=display.graphics. The stack shows that it's getting called from the FormattedText.Open event on the window.
Like I said, I'm simply updating from an older project. Any ideas on what the issue is? 

Have you added custom code such as a subclass? This may be the
source of the problem in the order in which things are done.


No, this is a straight FormattedText object, no subclass.

Here's the stack.

<pastedGraphic.tiff>


The actual error is here in FormattedText.AdjustDisplayPicture:

<pastedGraphic.tiff>
Just above this you see if display is nil, but in this case display is fine, but display.graphics is nil. 


Anyway, it looks like you invoking the drawing code somehow
during initialization when updates have been inhibited. I put into
preview 12 a check to prevent such a backdoor invocation which
should solve your problem. Please test it out and tell me the
results.
Essentially I'm still in the same boat as before. pv9 is what I was using before with no problems.
