What is the escape sequence for delete key?

[screw3d]

I tried googling for it but couldn't 😕 find anything useful. This is for Java if it makes any difference..

TIA.

Try casting it's ascii value as a char. \r\n e.x.: \r\n char escapeChar = (char) 27.

You want to delete the previous character? \b

If you mean backspace it's ascii code 8.
On a mac it's ascii code 127, and on PCs it sends ascii 0 followed by some other char (I forget what, shouldn't be too hard to make a test app...), but that has nothing to do with how you would read the key being pressed in a Windows GUI app. (VK_DELETE constant being passed in event message).

No telling what standard Java would use for this. I wouldn't be surprised if it varies depending on what host the JVM is running on.

Wow.. I think you are going into too much detail here 🙂

All I want is.. something like "\n" for end-of-line, "\\" for backslash, "\b" for backspace, and I'm looking for an equivalent for delete key, not backspace. 🙂

hmm, sorry about that, my example should be using 127 instead of 27.

It's been 15 years since this question was asked and this thread created, and if he hasn't figured it out during that long period, he might want to stop messing with Java. 😉
