Re: LEDgadget

Post by Guimauve »

Hello everyone,

Sorry to reopen a very old topic but I have completely rebuilt the original code of the LEDGadget(). I
have suppress the Global LinkedList used to store the Gadget related informations and I have make
them compatible with the use of #PB_Any for the GadgetID. The Gadget can be used like any other
standard Gadget. By the way I have change the name to TaskMeterGadget().

Since the code only use PureBasic internal drawing command so the code should run on all platforms
without any problems.

Edit : V1.0.3
- UserData added

Best regards.

thanks for sharing, nice work!!!

I suggest that you rename it LedBargraphGadget because there is another led gadget (http://www.purebasic.fr/english/viewtop ... led+gadget) and yours is a bargraph
