[SOLVED] Detecting if a text is selected in Autohotkey

Detecting if a text is selected in Autohotkey

I need to check if any text selected in Autohotkey. I have this function which works fine:

IsTextSelected()
{
    SavedClip := ClipboardAll()
    A_Clipboard := ""
    Send("^c")
    Errorlevel := !ClipWait(0.5) ; Wait for the clipboard to contain data
    if (!ErrorLevel) ; There is data on clipboard
        return (true)
    else
        return (false)
    ; Sleep(100)
    A_Clipboard := SavedClip
    SavedClip := ""
    return
}

But its too slow! Is there a way to speed up the process? Or is there another method to achieve that goal?

Solution

Here is the correct answer based on Descolada script. (requires UIA.ahk in the same folder as the script)

#Include UIA.ahk
IsTextSelected()
{
    try if (el := UIA.GetFocusedElement()) && el.IsTextPatternAvailable {
        selectionRange := el.GetSelection()[2]
        If selectionRange.GetText()
            return true
        else
            return false
    }
}
