Method Detail

isValid

protected boolean isValid(char character)

Description copied from class: TextField

Checks if the given character is valid in the sense of an implementing class. This method is called after each key press. Invalid characters are not shown, i.e. if this method returns false, the last typed character is not displayed.

Note: by default iso control characters are allowed, i.e. backspace, cursor keys etc. If you do not want to support them you have to explicitly forbid them via allowIsoControl(false).

Specified by:

isValid in class TextField

Returns:

true if character is valid, false otherwise

isValid

protected boolean isValid(java.lang.String input)

Description copied from class: TextField

Checks if the given string is valid in the sense of an implementing class. This method is called after the text input is finished. If this method returns false the input is not seen as to be completed.

Specified by:

isValid in class TextField

Parameters:

input - the current text content of the textfield.

Returns:

true if the string is valid, false otherwise
