Modificacion de un dato en un control textfield

[Raul_Juarez_Pulache]

Hola amigos de la Comunidad

Necesito resolver lo siguiente:
Tengo un textField en un ventana de una aplicacin escritorio, que generalmente contiene un dato para ser modificado, el mismo que se puede cambiar su valor sin ningun inconveniente, el problema que se me presenta es que si en algn momento el dato que se presenta inicialmente ya fue modificado y es incorrecto y se necesita mostrar nuevamente el contenido del textfield que estaba inicialmente antes de proceder con la modificacin.
Bueno yo supona que con pulsar la tecla ESC me debera mostrar el valor inicial, pero no sucede, si alguien conoce como resolver esta situacin, desde ya estoy muy agradecido me le haga conocer

Cordialmente
Raul

First off. Raul… I would either use Google Translate and/or post in the Spanish Language section

Hello friends of the Community

I need to solve the following:
I have a textField into a window of a desktop application, which generally contains data to be modified , the same that can change its value without any problem, the problem that occurs to me is that if at any time the data that was initially presented and it was modified and is incorrect and needs to show the contents of the text field that initially before proceeding with the modification again.
Well I supposed to press the ESC key should show me the baseline, but does not happen, if anyone knows how to solve this situation , of course I am very grateful I will make known

Cordially
Raul

Create a variable to hold the original value
When ESC key is pressed (KEYDOWN), replace the TEXT value with your variable
simple as that

Also if you are going to do this on more than one textfield, you might looking into creating a textfield subclass that incorporates this function so you don’t have to duplicate the code over and over
