Gadget ID#'s

The following is a percentage calculator I coded (my first ever app!).

You will notice that the #Gadget number for all of the frame and text gadgets is zero. ie. they are all sharing the same number. I did this because they are static elements which never change and are not referenced in any other parts of the code.

The app works fine, but my question is, is it really OK to use the same #Gadget number for more than one "decorative" gadget, or is this going to cause unforseen problems?

Thanks.




If OpenWindow(0,0,0,450,255,#PB_Window_ScreenCentered | #PB_Window_MinimizeGadget,"Percentage Calculator")
If CreateGadgetList(WindowID())
Frame3DGadget(0,10,10,WindowWidth()-20,70,"Find the value of the % of any given number",0)
Frame3DGadget(0,10,90,WindowWidth()-20,70,"Find the % of one number against another",0)
Frame3DGadget(0,10,170,WindowWidth()-20,70,"Find the % increase or decrease between 2 numbers",0)

Hi Xuul,

No problem to use same gadgetnumber for static gadgets.
The internal Windows handle will be unique, you can see this handle easely.

Code: Select all

debug TextGadget(0,20,44,60,12,"What is:")
debug TextGadget(0,123,44,30,12,"% of:")
debug TextGadget(0,261,44,60,12,"Answer:")

You can still delete this gadget with API, DestroyWindow_(Hndl)

Regards,
