I'm starting to explore the possibilities to have popup menus, but I'm having some troubles.

I do something like (found in this thread 

https://cycling74.com/forums/thread-considerations-when-using-t_jpopupmenu,

            int screen_x, screen_y;

            t_pt screen; int itemid;

            jmouse_getposition_global(&screen_x, &screen_y);

            screen.x = (double)screen_x;

            screen.y = (double)screen_y;

            itemid = jpopupmenu_popup(mymenu, screen, 2);

            post("result : %d", itemid);

so apparently the element with ID 2 of mymenu, when I pop it up, should be checked - but it's not! Nothing is checked.

Mymenu is correctly created and filled with

    jpopupmenu_additem(mymenu, 1, "A", NULL, 0, 0, NULL);

    jpopupmenu_additem(mymenu, 2, "B", NULL, 0, 0, NULL);

    jpopupmenu_additem(mymenu, 3, "C", NULL, 0, 0, NULL);

    jpopupmenu_additem(mymenu, 4, "D", NULL, 0, 0, NULL);

and then linked with a font via jpopupmenu_setfont.

By the way: when I have submenus linked with the same font, i have the feeling that the top level font is way smaller than the second level one...

Hello everybody,
I'm starting to explore the possibilities to have popup menus, but I'm having some troubles.

I do something like (found in this thread https://cycling74.com/forums/thread-considerations-when-using-t_jpopupmenu, thanks Luigi!)

			int screen_x, screen_y;
			t_pt screen; int itemid;

			jmouse_getposition_global(&screen_x, &screen_y);
			screen.x = (double)screen_x;
			screen.y = (double)screen_y;
			itemid = jpopupmenu_popup(mymenu, screen, 2);
			post("result : %d", itemid);

so apparently the element with ID 2 of mymenu, when I pop it up, should be checked - but it's not! Nothing is checked.
Mymenu is correctly created and filled with

	mymenu = jpopupmenu_create();
	jpopupmenu_additem(mymenu, 1, "A", NULL, 0, 0, NULL);
	jpopupmenu_additem(mymenu, 2, "B", NULL, 0, 0, NULL);
	jpopupmenu_additem(mymenu, 3, "C", NULL, 0, 0, NULL);
	jpopupmenu_additem(mymenu, 4, "D", NULL, 0, 0, NULL);
      ...
and then linked with a font via jpopupmenu_setfont.

thanks for answering. Actually it happens often that the checked value has to be dynamical.

Imagine this situation: one has 5 staves, and can click on each of them to change its clef (the popup menu is a list of clefs). The menu has to be just one, but I have to set different "checked" values when clicking depending on which staff has been clicked. I cannot simply define it once for all in jpopup_additem!

Thanks Vanille Béchamel, I'm afraid I didn't explain myself properly, sorry.

With your code, at the beginning "clef A" is ticked. Suppose that at a given moment one changes the clef into CLEF_B. Now x->clef has become CLEF_B, but there's no way to tell the menu that now the first element should not be ticked any more, and it is the second one which has to be ticked.

I have the feeling that once you add an item, either it is ticked, or it is not, and it'll be like that forever.

Except (and this is the solution I'm using now) if you destroy and recreate menus at each right click!

I just hoped to have a way to "switch" the tick in the menus without having to destroy/create them anew (which works perfectly, but I suppose it is more cpu-consuming?)

destroying/Recreating menus is exactly what I'm doing now, so I'm also quite happy that I don't have to change the structure of my code! :)

There's still this issue with the fonts: the same font associated to menus and submenus leads to different sizes. Does it happen to you as well? Is it normal?

You're probably right! :-)
