I search a example how to use the completion class, can't find until now, thanks.

This example is developed by an AI in response to your question.

Other sample:

Thanks for the answer, but on my Gambas this is not working, o i make things wrong.

(Click to enlarge)

I would fill a textbox (Datacontroltextbox) with a Database Field (Select Distinct ….), and the Datacontrolcombo is not working in this way….
I use Gambas 3.18.4 on Mint.

Me, say:
All the explanation and example code is developed by an AI for you, expressly. I think this is what you are looking for, if not, tell me.

AI, say:

Sure, here's the previous explanation and example in English:

In Gambas, the `Completion` property on a `Form` object is used to configure automatic completion of entries in a text field. This is useful when you want to provide suggestions or automatically complete user entries. Here's a simple example of how to use `Form1.Completion` to add suggestions to a text field on a form:


In this example, we first configure the `Completion` property of the text field `txtInput` on the `Form1` form. Three suggestions, "Apple," "Banana," and "Cherry," are added.

Then, we handle the `KeyUp` event of the `txtInput` text field. Each time the user presses a key, we search through the suggestions to see if any of them start with the text entered so far. If a match is found, that suggestion is set as the current suggestion in the text field. This provides auto-completion functionality for the user as they type.

Please note that this is a simple example. You can customize it to fit your needs and add more suggestions to the `Completion` property as required in your application.

 Does the AI produced code work?

Any other time I have seen ai used it produced a load of garbage code that looked a bit like gambas but didn't work because it was full of errors.

What are you trying to do?

Completion.class is kinda tricky but FileCompletion.class is easy


That's all you need to enable file completion for TextArea1


To use Completion.Class you have to make a class file and make it Inherit Completion, then give it a Fill() method.

I have attached a demo that uses Completion to make my own version of file completion.

In the main form i simply attach the MyCompletion.class to Textarea1 control.

Then I have created a MyCompletion.class that inherits Completion like this..


I wrote comments in the source so you can see what is happening.

THE IMPORTANT BITS…
You MUST make a class that inherits Completion and use that.
You MUST add the Public Sub Fill() method to your class
You MUST add your items to Me.List in the Fill method
you MUST set the Me.Start property to let completion know where to insert the text

Note: completion only works on TextBox, TextArea and objects that have an "Editor" property
Like a TableView for example you should assign like this…

Hope that helps.

And just a note to gambafeliz

As i suspected all that AI code was incorrect in a big way.

Please test anything you find via AI before posting or you are just wasting peoples time with incorrect code.
I know you meant well but none of that AI code made sense and had syntax errors all over the place.
Clearly your AI source does not really know gambas very well.
it starts off talking about Form.Completion and Completion is NOT even a property of Form.class (you should have spotted that)

I Say:
Andreas_K my advice would be to ignore anything the AI produced and read my post instead

AI Say:
blah blah guess guess garbage code

No offense intended gambafeliz but i hope you see all the problems with that AI code.
It is not only nonsense it is very wrong compared to the correct answer.

Respects

   

With all due respect, you already know me a little. The AI said that it only works on versions higher than my version, which is 3.15.2

Therefore I couldn't prove it.

On the other hand, it seems to me that the problem was that the person who asked did not know how to ask. Before asking questions you must give information that others understand and at the beginning it was not clear at all.

I knew that the first two batches of AI code were for nothing because it was not what the person asking asked for, but since he didn't ask properly, I gave him something similar but with an AI.

And since he also responds to me as if to give me more information, well then, I gave him the latest AI code that, in particular, seemed to me to be worth it but that I in particular could not validate because my version does not support Completion of Form.class

In short, there was always a good intention to help but I wanted the applicant to explain the question request more clearly.

Greetings to all.

Note: I don't doubt that your explanation is perfect or almost perfect, you already know that I have you as a super ninja of the Gambas code.

You're right, I asked him what version it works for and he answered this:   :roll:  :roll:  :mrgreen:

AI say:

The code I provided earlier is a hypothetical example and is not associated with a specific version of Gambas. Gambas is an evolving programming language, and features can vary by version.

As of my last update in January 2022, Gambas does not include a .Completion property by default in its standard library. It's always a good practice to consult the official Gambas documentation or up-to-date sources for information on the specific features of the version you are using, as language capabilities may have changed since my last update.

but thats rubbish too.
Nothing has changed that much in gambas
Form.Completion has never existed and does not now.

AI is like talking to someone who thinks they know everything but knows very little but has a good excuse for all the wrong answers.

have a look at the suggested code.
it makes no sense at all and wouldn't  work on ANY version of gambas.

Some examples of errors…

Form1.txtInput.Suggest = Suggestion   (txtInput.Suggest ??)
Form1.txtInput.Completion = NEW String[3]  (txtInput.Completion ??)

this code is a Sub() nested in another Sub() that you cannot do in gambas and also Completion.Selected does not exist.
' Handle the Selected event
$Completion1.Selected = Sub()
  ' Get the selected item from the autocompletion list
  $TextBox1.Text = $Completion1.SelectedText
End

???

It's utter nonsense

and i found the OPs question clear enough (obviously not a great English speaker but that's okay, i understood)
they wanted an example of using Completion.class
so that is what I posted. (I had to figure out how to use it first by reading the wiki help) @ /comp/gb.form/completion - Gambas Documentation

Not a load of nonsense created by a badly educated AI  

It's just garbage. I can see the errors a mile away,
I don't think it's helpful to post incorrect code,
I know you were only trying to help but i really do not see how a load of rubbish code full of errors form an AI is helpful?

I have refined this a bit.

Now it works better when pressing return.

Now if the text does not begin with / then it searches the open document for matching possible words list
like this…

attached is the test project.
(plus i replaced the attachment in the original post to be this version)

Well, you're right. As they say in fast services.

Kitchen ear!!!

Lesson learned, Mr.   8-)

Almost correct , i found a bug where if you do a file completion then do a normal one the Icons list does not clear

So start the statement for non-file completion part in the above example like this…

 Thanks both, the solution from BruceSteers works! When i bind Completion to a Datacontrol then everytime when the control is updatet, the completion popup will show, how i can unbind o destroy the completion popup after using them.
Thanks

Maybe like this…

There is also an _Activate() event that fires when the user selects a word from the list
you could possibly kill it there?

This my Completion Class, i testet to create the Completion Class in Form Open, Textbox Gotfocus, Textbox Keypress, but i still cannot destroy the class, evertime the datacontroltextbox change Text, the completion box appears. Testet to destroy in CMP Activate, Txtcontrol Lostfocus but still appears and if i close the MainForm is still not closed the app, i need to stop the application in the ide.
Is the Database Connection the problem, that the class cannot be destroyed?

it could be the Result property added to the class?
I do not really know

maybe add the following to your MyCompletion.class to kill the object…


_free should be called when in your other class you call hCompletion = Null


Also try killing hCompletion in Form_Close (if you open Completion popup but do not select anything then _Activate() is not called)

 I testet all, if i not use "Enter" or put the focus on another control, before closing the window, the app hangs and will not disposed (even i don't use a database), everytime datacontrol show another record, the autocomplete show up, even i dispose them before, i think is the combination with datacontrol….
Is there a way to override the behaviour of the datacontrolcombobox to show only data  what i added, whitourd binding to a table?
Thanks
