Raise event from STRING_KIND gadget without loosing focus?

[Sim085]

I have added a hook on a STRING_KIND gadget. The hook code is as follows:

    if(strcmp(obj->WorkBuffer, "Hello") == 0)
    {
        obj->Code = 'F';
        obj->Actions |= SGA_END;
        return (~0);
    }
    else
    {
        return 0;
    }

This works fine, when I insert the text Hello in the STRING_KIND gadget an IDCMP event is raised and I handle this through the main loop;

while(run)
{
    ...

    case GAD_ANSWER_TXT:
        if(msg->Code == 'F')
        {
            printf("Correct Answer Given!\n");
        }
        ...

However when I raise an event from the STRING_KIND Gadget I loose focus from it, i.e. a user cannot continue to type, unless I do not re-focus after the logic in the while loop using the following;

ActivateGadget(my_answer_field, my_window, NULL);

However this means that if I have some heavy code in while loop, focus might take some extra time to get back to the STRING_KIND gadget.


Therefore I was wondering, is there a way how I can raise an IDCMP event / message from a STRING_KIND gadget without loosing focus from same STRING_KIND gadget?

SGA_END menas exactly that: The user is done typing data into the gadget, and focus shall be lost, after sending the IDCMP_GADGETUP. This is what happens if you press RETURN in the gadget.


If you want some other form of feedback for your application, SGA_END is not what you are looking for. Instead, you could allocate a signal in your main task, and run into a Signal() in the string gadget hook, indicating for your main task that somethig is to be done about the string gadget.

1. track which gadget is the current gadget
2. enable IDCMP_RAWKEY events
3. handle the IDCMP_RAWKEY and update/check the gadget as you like

Hi Thomas,

I followed this example on signals and looks to be working:
