Does anybody have example code to transparant your form? like alpha
blend

Working with  LAZARUS v.2.2.0 and FPC 3.2.0

Cross compiling from WIN32 to Raspberry3 BullsEye

Hi,

I don't know if this is what you want, but in the Form properties, you
have 2 parameters:

AlphaBlend
AlphaBlendValue

If you set AlphaBlend to True and AlphaBlendValue to 128 for example,
your form and all tools inside it would be semi transparent.

General point if I may. Be very cautious of the RPi's homegrown window
manager (i.e. desktop environment), since it appears to omit passing
various hints, metrics and "understood relations" to the widget set.

I've got a very unpleasant situation trying to run (somebody else's)
app on an RPi, while running fine on a PC it's unusable on an RPi
unless the screen is something like 1920x1200 and in the end I had to
get a tiny 4K display which resulted in unreadable text.

Needless to say all involved parties disclaimed responsibility.
