@salass00

thank you
This is what I did before asking, but i've got strange behaviour.
The program compiled OK, but i had nothing on screen (i mean no screen, window and gadgets), then, after few seconds, the OS frozen

Edit: sorry, i've made two mistake. one of this is fundamental: i forgoto to open the class, first :P

It works now.

Thank you

Can't intercept the string events. This is the loop code:

ULONG result;
				while ((result = DoMethod (winobject, WM_HANDLEINPUT, NULL)) != WMHI_LASTMSG)
					{
					 (result & WMHI_CLASSMASK)
						{
					 WMHI_GADGETUP:
								switch (i)
									{
								case GID_STRING1:
									printf( "Contents: %s\n","Hello");
									cont = FALSE;
									break;
								case GID_OK:
								case GID_CANCEL:
									cont = FALSE;
									break;
								default:
									if (i < TB_MAX)
										Printf ("gadget up: %s\n", tbname[i]);
									else
										Printf ("gadget up: %ld\n", i);
									}
								break;

What i've forgot this time?

Solved:

I've add the following:
GA_RelVerify, TRUE,
GA_TabCycle, TRUE,

and now the event get intercepted

Btw, how to refer to the string and get the content of the string?
if i do:

struct Gadget *gadgets[GID_LAST];
printf( "Contents: %s\n", ((struct StringInfo *)(gadgets[GID_STRING1]->SpecialInfo))->Buffer);
the program crash and the system freeze soon after

thank you

Thank you Danjiel,

i will try as soon as back home.

As for the freeze problem, i should check if i have disposed all the objects, or disposing the window object dispose all the children too?

Trying to get the string content i get:

error: 'struct IntuitionIFace' has no member named 'IIntuition'

I use __USE_INLINE__ as switch on the command line. What should i use instead?

Btw, omitting this switch cause me to get tons of warning and undefined reference for my actual code as follow:

"In that case don't use "IIntuition->" or other interface names in function calls."

Sorry, but i'm not an expert.
:(

Hi,

thank you for your patience. I know i'm boring you. Sorry for this.

I changed all the prefix in the following way:

IDataTypes->NewDTObject
IIntuition->IDoMethod
IDataTypes->GetDTAttrs
ILayers->SetBackFillHookAttrs
IDataTypes->DisposeDTObject
IIntuition->OpenWindowTags
IIntuition->CloseWindow
IDOS->AddPart
IIntuition->NewObject
IIntuition->GetAttr
IIntuition->GetAttrs
IIntuition->SetAttrs
IDOS->Printf
ILayers->CreateBackFillHook
IIntuition->OpenScreenTags
IGadTools->GetVisualInfoA
IExec->Wait
IIntuition->ItemAddress
IGadTools->FreeVisualInfo
IIntuition->CloseScreen
IIntuition->DeleteBackFillHook

i still have this problem:

warning: passing argument 2 of 'IIntuition->GetAttrs' makes pointer from integer without a cast
error: 'struct IntuitionIFace' has no member named 'DeleteBackFillHook

Thank you

I used the Layers->DeleteBackFillHook() and now it's ok and compile (my mistake, sorry)

Here's is the code related to the warning message: "warning: passing argument 2 of 'IIntuition->GetAttrs' makes pointer from integer without a cast"

IIntuition->GetAttrs(GID_STRING1, STRINGA_TextVal, (uint32 *)&stringContents, TAG_DONE);

Note: the code get compiled, but as soon as i test the string gadget pressing enter, i get a DSI error
