LlTextBox

Shows a dialog box on avatar's screen with the text message. It contains a text box for input, any text that is entered is said by avatar on channel when the "Submit" button is clicked.

integer listener;
 
// this is a user-function, it doesn't have a return type
remove_listener()
{
    llListenRemove(listener);
}
 
default
{
    touch_start(integer total_number)
    {
        key id = llDetectedKey(0);
        remove_listener();
 
        integer randomChannel = ~(integer)llFrand(1000.0);
        listener = llListen(randomChannel, "", NULL_KEY, "");
 
        llTextBox(id, "Some info text for the top of the window...", randomChannel);
    }
 
    listen(integer channel, string name, key id, string message)
    {
        // PUBLIC_CHANNEL has the integer value 0
        llSay(PUBLIC_CHANNEL, "You wrote: " + message);
 
        remove_listener();
    }
}

If the user hits "Enter" before clicking the "Submit" button, there will be a final carriage return in the message. This code removes it.

integer listenHandle;
 
default
{
    touch_start(integer num_detected)
    {
        listenHandle = llListen(91, "", NULL_KEY, "");
 
        key id = llDetectedKey(0);
        llTextBox(id, "Type a message and click \"Submit\".", 91);
    }
 
    listen (integer channel, string name, key id, string message)
    {
        llListenRemove(listenHandle);
        integer messageLength = llStringLength(message);
        string lastMessageCharacter = llGetSubString(message, messageLength - 1, messageLength - 1);
 
        if (lastMessageCharacter == llUnescapeURL("%0A"))
        {
        //  Ignore final carriage return embedded in the message
            message = llGetSubString(message, 0, -2);
            llSay(PUBLIC_CHANNEL, "Final carriage return removed.");
        }
 
        llSay(PUBLIC_CHANNEL, message);
    }
}

Instead of mouse clicking: "Submit", you can use keyboard keys: press Tab ⇆ and then Enter ↵
