Maximum number of gadgets

[neuronic]

Hi

I am working on a small application and I would like to use lots of gadgets. Is there any way I can use more gadgets then 10.000? If i create a lot I get the message: #Gadget object number is very high (over 10.000).

Any ideas?????

How can a small application have more than 10000 gadgets????

I believe that is only a warning from the debugger you can still continue execution.

I'm not sure but i think the real limit is 65000

He probably doesn't. He's may be referrring to a gadget by an improper id for the gadget in question.

I thought the message was 100,000 not 10,000 but my references to it may have been something other than on a gadget.

cheers

For files it is a 1000, had that exception yesterday try-ing to open a file with the number 1005, so why not for gadgets?

Hi again

I would really like to have that many gadgets. It is not a wrong id number or anything similar. The application is a simple map editor, where i need ImageGadgets depending on the size of the map.

If I turn the debugger off the execution goes on, but there are no more gadgets created.

Off course I can use a different method, where i don't need thousands of gadgets, but using this is the easiest way.

Without #PB_Any you can create only 10000 Gadgets.
Use #PB_Any, you can create Gadgets with max from OS

I almost replied with ts-soft's answer, as I believed it to work like that. It does work like that with windows as opposed to gadgets. But I ran a little test and it seems like there is an upper limit of 9999 for gadgets:

Code: Select all

Dim gadgets(100000)
OpenWindow(0,0,0,800,600,"")
CreateGadgetList(WindowID(0))
CreateImage(0,1,1)
gadgetcount = 1
gadgets(gadgetcount) = ImageGadget(#PB_Any, Random(799),Random(599),1,1,ImageID(0))
While IsGadget(gadgets(gadgetcount)) <> 0
  gadgetcount+1
  gadgets(gadgetcount) = ImageGadget(#PB_Any, Random(799),Random(599),1,1,ImageID(0))
Wend
Debug "Number of gadgets created: "+Str(gadgetcount)
Repeat:Until WaitWindowEvent()=#WM_CLOSE

See what result you get, but I can't ever get more than 9999 successful gadget creations.

[ts-soft]

You can Create Gadget from 0 to 9999 and Window from 0 to 4999 with
Constants! More only with #PB_Any

See what result you get, but I can't ever get more than 9999 successful gadget creations.

I modified your sample code to create 9000 gadgets with constants 1-9000 and then create as many additional ones as were possible with #PB_Any. I still only came to 9999 total. So it seems that combinations of constant numbering and #PB_Any doesn't seem to increase the total possible.

I would say If u have 10000 Gadgets ure program will be so slow that u want to look for anoothert possiblility. In U#re case i would use an openscreen (also faster)

It's probably a Windows limitation, as each control is an handle and 10 000 handle for only one application is way too much. Somebody can do a loop of CreateWindowEx() to see if it's reproducible with API only ?

BTW, the debugger warning about the maximum reached is just a warning, it doesn't prevent the creation.

[netmaestro]

Good idea, Fred:

Code: Select all

hwnd=OpenWindow(0,0,0,320,240,"")
Repeat
  MyText=CreateWindowEx_(#WS_EX_LEFT,"Static","",#WS_CHILD|#SS_CENTER,0,100,200,20,hwnd,0,GetModuleHandle_(0),0) 
  cc+1
Until mytext=0
Debug cc

This code is debugging 9999 here. I vote for Windows limitation

[edit] The max# of open windows seems to be 10000, as if I remove the OpenWindow() from the above snip and take out the #WS_CHILD style, it dies at 10000 instead of 9999.
