Double Menu Requesters

[tygre]

Hi there!

I was reading some C programming tutorial on Obligement (in English) and discovered the "double menu requesters"... What puzzles me is that I don't recall ever using such requester, as a user

So, when should double-menu requesters be used? Would you have example in existing programs?

Cheers!

An example in C is provide in the RKM (Rom Kernal Manuals) for Kickstart 1.3, it can be found on http://aminet.net/package/dev/src/RKMCompanion. Hope that helps . The code use a gfx bitmap for RoundRects. You will find it extracted in the Intuition/ drawer, I can't remember what drawer in the Intuition folder I'm guessing the Requestors

I don't ever recall using such a requester as well.

The method, and intuition requesters in general (not auto-requesters), run out of fashion rather early on. Concerning requesters, the only program I remember that uses RMB-Requesters was the "Profimat" Assembler from Databecker.

Hi RedBlade and Thomas and thank you!

I was afraid that I missed out on a major feature all these years

Cheers!

Too much work to set up and check?? Not enough examples??

It's too bad this wasn't more widely adopted way back when. It's very reminiscent of modern context menus and touch-and-hold UI paradigms. It also seems to foreshadow Commodore's "checkmark menu" plans in the 1993 DevCon notes.

Once again, Amiga was at the forefront of innovation!

Good point Matt_H!

It's not really complicated. You allocate a struct Requester, documented in , add gadgets to it with AddGList() - note well that this call has an additional argument that specifies the requester this goes in - and then SetDMRequest() to the window.

A RMB double click will bring the requester upfront, will block its input, and you'll then receive the IDCMPs from the requester.

ClearDMRequest() removes it.

Anhow, the whole construction is ancient, and at least in kick 1.3 partially buggy. String gadgets in requesters had some limitations, for example. GadTools does not work in requesters.

If you want to see a Requester in "life action", then SetVNC (from ViNCEd) installs a requester in the hosting console window. Not a double-RMB requester, though.
