Is it possible to assign FLAG on a case-by-case basis?

Is it possible to assign FLAG on a case-by-case basis? - 12/28/21 15:36

Hello guys,

I ran into a problem and no matter what I did, I couldn't find a solution. I'm trying to develop a content where the user is asked a question and after a while I want them to remember the information given for that question.
If the user writes a response longer than 50 characters real-time while entering the response in the response field, I want to make the response go one line.
I was able to do this with the WWRAP flag feature, but even if the user types a character, the cursor immediately goes to the bottom line. I want to prevent this.
As soon as the user reaches 50 characters while typing the reply, I want to make sure that the cursor goes down to one line and writes the reply.

In other words, as soon as the user reaches 50 characters, I want to enable WWRAP in the code I shared below. How can I do that?

Code

TEXT* retention_name_txt = 
{
       pos_x = 70;
       pos_y = 180;
       layer = 11;
       red=0;
       green=0;
       blue=0;
       font = "Calibri#30";
       string(retention_name_str);
       flags = FILTER /*| WWRAP*/;
       size_x=1800;
}

So you could do:

Code

retention_name_txt.flags &= ~WWRAP; // to reset
retention_name_txt.flags |= WWRAP; // to set

Also, you could check for the length on the string with str_len.

But I would personally use imgui for this purposes, cause it's very simple and easy to use + offers much more than acknex panels/texts has.
You can find it here:
Imgui Lite-C Development

Best regards.

Hi 3run,

Thank you for replying. I'll try the flag method you said. But IMGUI looks really nice. What I want is to create a text box that supports multi-line typing and let the user type in this field. On the other hand, I don't know how to integrate IMGUI's textbox feature into my own project.

It's actually quite easy to use, just download the demo and study the code, it's not as hard as you might have imagined it. Multi-line is created withing few lines of code!

Thanks for your response 3run.
How can I write the code to enable WWRAP flag when the number of characters entered exceeds 50 as the user continues to enter characters in the text box?

Actually, what I want to do is exactly; real-time consideration of the number of characters entered as the user enters a response, and activation of the WWRAP function when the number of characters exceeds 50. I could never do this.
