Re: [BLACKBOX] limiting integer values in interactor field

It can be frustrating that the Dialog module does not send a lostfocus opcode to notifiers. However, one purpose of validating the field is to prevent the operator from sending invalid data to whatever the next step in the process is. In that situation I generally use guards to check the value of the field, and disable the guarded controls (eg an OK button) until the field is valid.

Subject: [BLACKBOX] limiting integer values in interactor field



Hello all,

 

there is an problem which came up recently: I wrote a little character sheet checker for a role playing game. The basic attributes are integer values, some of them between 3 and 18 (3W6 in short).

 

What I did: I had the Notifier procedure for this field check, if the entered value is in the valid interval and setting it to the upper respectively lower boundary value. Safe.

 

The problem: If you want to enter a value > 10, you first have to type the letter <1>. Right now the notifier kicks in and changes it to 6 which is obviously undesired.

 

Is there an elegant way to check the content of a field AFTER the input has been completed?

 

I mean another way than putting a button there and having the user clock on it after each number he has entered. I could not for instance find an event like “onLeave” (moving the focus).

 

regards

gunnar
