Wow! That's great Bernd. I neevr imagined code like that. Was wondering if I need to create a structure but that's as far as that thought went!!

I am going to have a play and try to adapt the code to led images (that I have in a folder)

P.S I have a folder with your Scan2Image in it I am still playing with:):)

Hi, hi,

of course of your question, the PB world has now a LEDGadget()

I had no LED images, so I created this stuff

Btw.: I updated my code above.

Now you can also have a border around the LED and you can change the color at runtime with LEDGadgetSetAttribute()

Fangbeast · Post by **Fangbeast** » Fri Apr 20, 2012 10:00 am

HAHA, excellent!

I had no LED images, so I created this stuff

Now I have to figure out how to modify your code to work with real imagegadgets as I have some nice led images to use.

Btw.: I updated my code above.

More to study:

Now you can also have a border around the LED and you can change the color at runtime with LEDGadgetSetAttribute()

Better and better.

That's simple:

You have only to replace the lines with:

Code: Select all

LEDGadgetSetState(LEDList()\GadgetNo, LEDList()\State)

With something like this:

Code: Select all

if LEDList()\State
  SetGadgetState(LEDList()\GadgetNo, ImageID(XYOn)
else
  SetGadgetState(LEDList()\GadgetNo, ImageID(XYOff)
endif

Of course you have to asign the GadgetNo somewhere.

Maybe you should extend the LEDList() structure by fields for the On- and Off-ImageID,
than you can use something like this:

Code: Select all

if LEDList()\State
  SetGadgetState(LEDList()\GadgetNo, LEDList()\OnImageID)
else
  SetGadgetState(LEDList()\GadgetNo, LEDList()\OffImageID)
endif

So you can set individual on-/off-images for each LED.

So you can set individual on-/off-images for each LED.

Or you extend the LEDList() structure by an Array() for the On- and Off-ImageID,
than you can use something like this:

Code: Select all

  SetGadgetState(LEDList()\GadgetNo, LEDList()\ImageID(LEDList()\State))

It's a bit shorter

I was playing around after tea and figured something out myself finally and got it working. Now I will work it over to trigger on events rather than buttons but thanks all for the great suggestions and examples!
