Like an addressof (subroutinelabel) function, and a gosub address?
...
I think what you are describing is what I know as a "state engine".
The caller assigns a value to a 'state' variable. Hence, the sub knows who called it.
Also, (somebody correct me if I have this wrong) subroutines can be called by using a string to hold the name. An array of strings could enable calling subroutines by variable value. A similar function could also be structured within a select/case function.
Maybe not exactly what you are after but a potential workaround?

Nice, thank you.
No, this info is not avalable but could be implemented
You could simply cut off the text when it is longer than the textarea can display, and then the user can just call len(GUI.GetText(textfieldhandle)).

    - Fixed the repetitive event on button when the text changes inside
    - Implemented GUI.GetText (same as VGAGUI.GETTEXT)
    - Implemented GUI.Visible obj, visible (0=hidden, 1=shown)

Thanks, you're the best. That'll make things much easier for me.

I'm always switching between several boards, but at the moment I'm using an ESP32-2432S028, so standard ESP32 without PSRAM.

What is the module that you are using ? ESP32 classic or ESP32-S3?

edit:
I implemented the tft.gettext and the tft.textarea functions ... if you want try just let me know what is the version that you are using so that I can export the right .bin

You can eventually use an external BLE keyboard or USB keyboard if you are using the ESP32-S3

[Local Link Removed for Guests] wrote: [Local Link Removed for Guests]Mon Dec 09, 2024 5:53 pm Well, building a dynamic GUI in standard BASIC seems like a very dumb idea.

Maybe I will switch to Micropython and LVGL.
No, it is probably not a dumb idea ... it is probably just a questions of methods.
