LiveCode Forums.

While in the IDE I would like to be able to edit the selectedObject (modify it's properties in script). Is there somewhere to find/retrieve the name of the selectedObject? (PS for those who read Andre's latest book; "Development Oriented Development", he references this function on Pg 24 but I can't figure out how he gets it to work). I've tried putting the name of the "selectedObject" into the msg box, or an answer dialog but I never get anything. However the msg box seems to get and display the name quite handily. Anyone know how it does that? (Hope I haven't asked too many questions!).

Thanks
Mark

I don't have the book but you could try Kelly

Hello, if what you are trying to do is a plugin. I advise you to read this post: https://livecode.com/how-to-create-plug ... e-8-0-ide/.
In it he explains how to subscribe to certain messages from the IDE. Among them to ideSelectedObjectChanged, within can call funcon the selectedobject or the selectedobjects. The last one will have a reference to a selected object on each line.

Hi.

Kelly nailed this with "the selectedObject". That is just what that function is designed for. In fact, it can return any number of selected objects.

Whatever the message box can do, a handler can do better. Are you sure that when your handler calls this function, that there is indeed an object selected? You will get empty if not. Otherwise it is very straightforward.

And the title of your post is interesting. But in the context of your question, nothing about a selected object is "stored" anywhere, simply by virtue of it being selected. But there is a property of an object that is selected, and is, not surprisingly, known as "the selected". This can be either true or false, depending on, well, I bet you already know. This is a basic underpinning of LiveCode. Properties reflect the current state of everything. They change, and are changed, by the user, the system, whatever. It is the setting and getting of properties that makes the world go round.

You have not asked nearly enough questions. Keep at it.

This.
If, for instance, you have created your own palette to choose properties to set, or a button to apply properties by running your handler, then you might find the selectedObject is no longer the object you originally selected.

Thanks everyone. You have given me lots to think about. If I get stuck again I'll post an example.

Cheers,

Hello marksmithhfx. Create a small sample extension using the LiveCode API. Which was introduced in version 8 and explained in the post I previously shared here.
If you are doing a plugin, which is what I understood. It is better to use this API.

It is a simple and improvable extension. What it does is display the properties of the selected object. As long as the object is not a widget: D.
Happy coding

Hi Andre, I read the post with considerable interest, and I think you are correct, the mechanism is explained in/by the IDE API. Will give this a try (but I see you've posted a stack so I will be downloading that and giving it a try. Thanks a bunch)!!!

Hi Andre, I just tried unzipping this and apparently I am not equipped with an un-RAR application. Would you recommend one?

Thanks

Hello, I am on Win 10 and I use winRAR, here is the same example. Now in a ZIP

RAR Extractor Free is in the Mac App Store and worked for me.

Dear @andresdt, thank you for this code - it solved the issue I was just about to grapple with!
This forum is a goldmine
But only thanks to the generosity of developers like yourself - thank you!
