[ I'm a line-eater and I'm O.K., I eat mail at night and I sleep all day ]
I'm having problems getting potentiometer gadgets to work the way I
would like. Intuition provides GADGIMMEDIATE flags for GADGETDOWN
IDCMP events, FOLLOWMOUSE flag for MOUSEMOVE events, and
RELVERIFY for GADGETUP events. The problem I have is that
RELVERIFY gadgets only provide GADGETUP events if the mouse is
over the gadget at the time of left mouse button release.
I would like to have a gadget flag that guarantees GADGETUP events
if you get a GADGETDOWN event.
I have an operation I would like to do everytime the user uses a
particular potentiometer gadget. The operation is too time consuming
to do as the potentiometer is sliding, so I'd like to defer the
operation until the user let's go of the potentiometer gadget.
The results of the operation depend on the value of the slider
at the time of it's release.
Because of a RELVERIFY gadget's operation I can't be sure that
I'll get the GADGETUP event, and then can't perform the desired
operation.
In my application, it is as important to know that the user has
stopped using the gadget as it is that they started using it.
I can simulate my own slider using MOUSEBUTTONS and MOUSEMOVES, but
then I have to slide the knob and clear the container and all that
other stuff.
Is there some other flag tha I don't know about that will do what I
want? If not then is it reasonable to add a new flag for 1.4?

Well, it doesn't exist at present. You could turn on Intuiticks when you get the gadgetdown, and look at the mousebutton qualifiers (I believe they are valid). Don't forget to turn them off when done. >I have an operation I would like to do everytime the user uses a >particular potentiometer gadget.

Prop gadgets appear to produce gadgetups with relverify, even if the mouse is off the gadget. Relverify really only applies to boolean gadgets (in terms of the verify function).

Silly me.... >-- >Randell Jesup, Commodore Engineering {uunet|rutgers|allegra}!cbmvax!jesup So I misstated and oversimplified my problem. I hate it when that happens. I'll try again. Potentiometer gadgets do not allow you to render into the container (except for the knob). I would like to render into the container. So I want to simulate a slider with gadget down, mousemoves, gadget up. I can easily do it with MOUSEBUTTONS, but then I need to check to see that the mouse cursor is inside my simulated gadget (I also have to ignore mousebuttons when I push other gadgets...) Instead if I used a gadget then the "is it inside the container" check would be handled by Inutition. If I had a GADRELEASE flag, then it would be really simple to simulate a potentiometer gadget just by setting the GADGIMMEDIATE|FOLLOWMOUSE|GADGRELEASE flags. The only thing that would be lacking would be unit-less potentiometer values (the value from 0-1 in scaled in format). If (in 1.4) there was a GADGRELEASE flag that was usable for BOOLEAN gadgets then it would be much simpler to simulate sliders, and we could avoid using MOUSEBUTTONS (and we wouldn't have to add code to ignore them when we don't want them.) I hope this clarifies things. Kevin -- UUCP: kevin@uts.amdahl.com or: {sun,decwrl,hplabs,pyramid,seismo,oliveb}!amdahl!kevin DDD: 408-737-5481 USPS: Amdahl Corp. M/S 249, 1250 E.

When Intuition does not send you a GadgetUp maybe it will provide you with a SELECTUP since the button-event has no meaning to intuition?! If your duty is too consuming to be done for each movement do it only for the last of a bunch of arriving movemets: while (imsg=GetMsg(w->UserPort) { if (imsg->Class==MOUSEMOVE) { ReplyMsg(imsg); } else { ReplyMsg(imsg); break; } } ...

If the user releases the mouse button inside the hit box (with RELVERIFY), the message GADGETUP is sent. If the mouse is outside, there is no message but your gadget is no longer selected. I had the same problem as you. Here is my solution, it is not the best I could hope but it works. When the GADGETDOWN message is sent, I wait until: - the SELECTED flag disapears (button released out of gadget) - or the GADGETUP message arrives (button released inside gadget) I think too this system of flags is not complete. Any suggestions for 1.4? Olivier Vayssettes Universite de Bordeaux - France

No gadgets allow you to render into them, properly speaking. The
imagery support for gadgets is enumerated in the manual. There is no
guarantee that direct rendering will work.

How hard is that? I use ptInBox( mousept, gadgetbox ) which took
almost 4 minutes to write, comment and compile.

If you release a boolean gadget when not over a gadget, you will get
a SELECTUP MOUSEBUTTONS message, if your idcmpflags request.
)I hope this clarifies things.
You appear to have an unnatural fear of mousebuttons.
