Option Menu to show menu item by code - Solved

[DR White]

I have banging my head now for over 3 hours trying to figured out,
if it is possible to get an Option Menu to show menu items with some program instructions.

If anybody knows how, I would greatly appreciated it.

Thanks,

David

I wonder if you could explain what you mean a bit more clearly.

Do you mean a menu that, when you click on it, shows the underlying code/scripts
behind menu items?

If this is what you mean then it really isn't necessary as one can "fool around"
in the IDE and look at the underlying code within it as much as one wants already.

If, alternatively (and your title is a bit difficult to interpret) you want to make a menu drop down
"magically" powered by script that's a different thing altogether, and I wonder what the point of
it would be.

richmond62,

I want to make a menu drop down
"magically" powered by script.

I am working on a special IOS app that I need the Option Button menu (IOS picker) to open, when the card is open.

Thanks

LC is good at magic.

There were threads on this a while ago, but I cannot find them. But start with this. Make an option menu. Make another button. In that other button's script:

Code: Select all

on mouseUp
   click at the loc of btn 1
end mouseUp

Those other threads explored similar kluge methods of selecting menuItems of interest once the menuItems were displayed. This can all be re-created. Can you get going on this?

Craig,

WOW! That works BEAUTIFULLY!

The LiveCode Forum with people like you and many others make using LiveCode worth every dollar!

Thanks,

Well, glad you like it.

But as for "magic", do you see how the LC environment, in one line, can support such klugey marvels?

Craig

[richmond62]

Well, up to a point.

This doesn't work:

on mouseUp
click at the loc of btn "Tools" of stack "revMenubar"
end mouseUp

nor does it work between any 2 open stacks.

This is a pity as the ability to do this would be very useful indeed.

I think one has to be on a card in order to "click"on it. I see no reason why this should be so, as you say. So you must navigate before clicking.

I suppose one could "navigate" by code as well . . .

This works:

on mouseUp
set the defaultStack to "revMenubar"
click at the loc of btn "Tools"
end mouseUp

Good fun. If you can figure out a way to type arrow key and Enter key messages you could simulate all sorts of user actions in menus.

[dunbarx]

The way around all this is to create a "clicking" message:

Code: Select all

send "clicking" to objectpathName

and then in a card script

Code: Select all

on clicking
   click at the loc of the target
end clicking

Craig

[richmond62]

Good fun.

Yup.

I wonder how one could do something like this:

(pseudocode)

send (controlKey & 3) to btn "View"

This works:

on mouseUp
set the defaultStack to "revMenubar"
click at the loc of btn "View"
select menuItem 3 of btn "View"
end mouseUp

Mind you; that's pretty silly when a "go next" would have done the trick anyway.

The only "slight snag" is that you don't see the menuItem high-lighted.

Also: not a bad idea to have a second "click at loc of" after the select so the
menu doesn't keep hanging down.

That triggers the script for the menuitem, but doesn't dismiss the menu, and doesn't even require the menu be dropped down. Might be nice if there was a way to truly simulate selection of a menu, with item flash and all.

PS: Why post screen shots of your scripts instead of just posting the code? The screenshots take up more space, and don't allow anyone to copy the script, requiring them to re-type it.

Point taken.

click at the loc of menuItem 3 of btn "View"

didn't do any good at all.
