[REQ] Control selection during browse mode

[Emily-Elizabeth]

Does anyone have any code that will allow one to select a control during browse mode? The code would have to be GPL as I am using the Community Edition of LiveCode.

Hi Emily-Elizabeth,

you can simply do this e.g. in a card script like in my example, see screenshot
-> set the selected of the target to true
Also works in BROWSE mode.

Maybe you want to insert this into front when neccessary and remove it later,
depends on when you want to select objects.


Best

I'm building a visual database editor and the user will switch between "browse" and "edit" modes, so I just need this to work in "edit" mode. Thanks for the info.

Edit: you can see the work in progress https://github.com/emily-elizabeth/Database-Designer

Can't resize or move the controls though.

[Emily-Elizabeth]

Setting the cantSelect of the tools pane means that they are "live" even when in edit mode (so the other controls can be selected, moved and resized).

[Klaus]

Aha, well, you didn't mention that!
Editing is a complete different story and not so easy.

Setting the cantSelect of the tools pane means that they are "live" even when in edit mode (so the other controls can be selected, moved and resized).

Que? Sorry, no idea what you mean? There is no "canSelect" property anywhere.
Maybe you just mean the "Pointer Tool"?

This is what EE means:

And in the context (though she doesn't seem to have mentioned it explicitly) a 'canSelect' property would be nice too!

Ouch, three blind mice, me being one of them...

Actually, Klaus isn't blind at all. There really is no "canSelect" property.
But there is a "cantSelect" property (emphasis on the t).
However, contrary to what Emily suggested, the cantSelect property, when set to true, actually prevents the user from being able to select the control.
What Emily seems to want to do is be able to select the controls, and resize and move them, while in browse mode.
Not that easy in browse mode.

I AM blind, I missed the T!

It is extremely easy to select something in Browse mode:

Code: Select all

on mouseUp
   select me
end mouseUp

and the result is "all very sweet and sexy":

BUT that's about all you will get, as that does NOT allow you to resize or move the object about.

You can, of course, do this:

Code: Select all

on mouseDown
   select me
   grab me
end mouseDown

which allows you to move the object around and shows the selected dots . . .

Don't feel bad, it's a hard property to find as it's not listed in the Inspector palette, but some sleuthing and trying got it figured out

[richmond62]

I don't feel bad: but I do feel slightly angry with myself that I haven't managed
to work out how to do it.

[Emily-Elizabeth]

Everything that you don't want to move/resize set the cantSelect to true and then you can create a new control, switch to the edit tool and then you can select/move/resize the new control.

[richmond62]

Wow: you are a right crafty so-and-so!

I should, perhaps, 'remind you', that the origin of the word 'crafty' in Anglo-Saxon
has NO negative connotations: 'cræftiȝ" meaning 'clever'.

Although setting "Everything that you don't want to move/resize set the cantSelect to true"
could be long-winded, and, what if you want to muck about with one of those at a later date?
