/**
|
|
|
5 |
* This file defines a number of simple classes (virtual base: ConfParamW)
|
|
|
6 |
* which let the user input configuration parameters.
|
|
|
7 |
*
|
|
|
8 |
* Subclasses are defined for entering different kind of data, ie a string,
|
|
|
9 |
* a file name, an integer, etc.
|
|
|
10 |
*
|
|
|
11 |
* Each configuration gui object is linked to the configuration data through
|
|
|
12 |
* a "link" object which knows the details of interacting with the actual
|
|
|
13 |
* configuration data, like the parameter name, the actual config object,
|
|
|
14 |
* the method to call etc.
|
|
|
15 |
*
|
|
|
16 |
* The link object is set when the input widget is created and cannot be
|
|
|
17 |
* changed.
|
|
|
18 |
*
|
|
|
19 |
* The widgets are typically linked to a temporary configuration object, which
|
|
|
20 |
* is then copied to the actual configuration if the data is accepted, or
|
|
|
21 |
* destroyed and recreated as a copy if Cancel is pressed (you have to
|
|
|
22 |
* delete/recreate the widgets in this case as the links are no longer valid).
