create an event in internal queue

Hi

I wonder if its possable to add my own events to the waitevent queue from within c. im currently writing a ftp client and have listbox item drag and drop between 2 listboxs and would like to add these events and hwnd pointers to the maxgui queue

anyone done this or now if its possable without hacking maxgui mod?

thanks

Hi,

try this:
Test-File.bmx:

Strict
Framework brl.blitz

Import brl.eventqueue 'You can see that it only needs the eventqueue module,
                      'the maxgui is actually not needed

Import "Test-File.c"



AddHook EmitEventHook , Func 'Add a hook to show that the events can also be
                             'received by using hooks

CallCStuff 'go straight into c

WaitEvent 'let's get an event from the queue

WriteStdout "Event received by queue: " + CurrentEvent.ToString ( ) + "~n"


Function Func:Object ( id , data:Object , context:Object )
  WriteStdout "Event received by hooks: " + data.ToString ( ) + "~n"
  Return data
EndFunction

Extern
  Function CallCStuff ( )
EndExtern

Test-File.c:

#define EVENT_GADGETACTION 0x2001
#define BBNULL &bbNullObject

extern void * bbNullObject ;
void * brl_event_CreateEvent ( int id , void * source , int data , int mods , int x , int y , void * extra ) ;
void brl_event_EmitEvent ( void * event ) ;

void CallCStuff ( )
{
  brl_event_EmitEvent ( brl_event_CreateEvent ( EVENT_GADGETACTION , BBNULL , 13 , 15 , 7 , 4 , BBNULL ) ) ;
  //I'm using some random numbers in the event's fields to show that there're really carried with
}

(I'm not the best c-programmer, I know... but it works)

Of course you can post an event directly to the queue by calling PostEvent, however I suggest to use EmitEvent instead, which will post it to the queue as well, but also allows users using the hook-system to get these events.

If it runs successfully, it should give this output:

Event received by hooks: GadgetAction: data=13, mods=15, x=7, y=4, extra=""
Event received by queue: GadgetAction: data=13, mods=15, x=7, y=4, extra=""

Process complete

I hope I could help you.

thanks Fabian, this works like i hoped :)

thanks again
