|

|
|---|
| 59 |
|
|---|
| 60 | The QIntValidator class provides a validator which ensures
|
|---|
| 61 | that a string contains a valid integer within a specified range.
|
|---|
| 62 | <p>
|
|---|
| 63 | <p> Example of use:
|
|---|
| 64 | <p> <pre>
|
|---|
| 65 | <a href="qvalidator.html">QValidator</a>* validator = new QIntValidator( 100, 999, this );
|
|---|
| 66 | <a href="qlineedit.html">QLineEdit</a>* edit = new <a href="qlineedit.html">QLineEdit</a>( this );
|
|---|
| 67 |
|
|---|
| 68 | // the edit lineedit will only accept integers between 100 and 999
|
|---|
| 69 | edit-><a href="qlineedit.html#setValidator">setValidator</a>( validator );
|
|---|
| 70 | </pre>
|
|---|
| 71 |
|
|---|
| 72 | <p> Below we present some examples of validators. In practice they would
|
|---|
| 73 | normally be associated with a widget as in the example above.
|
|---|
| 74 | <p> <pre>
|
|---|
| 75 | <a href="qstring.html">QString</a> str;
|
|---|
| 76 | int pos = 0;
|
|---|
| 77 | QIntValidator v( 100, 999, this );
|
|---|
| 78 |
|
|---|
| 79 | str = "1";
|
|---|
| 80 | v.<a href="#validate">validate</a>( str, pos ); // returns Intermediate
|
|---|
| 81 | str = "12";
|
|---|
| 82 | v.<a href="#validate">validate</a>( str, pos ); // returns Intermediate
|
|---|
| 83 |
|
|---|
| 84 | str = "123";
|
|---|
| 85 | v.<a href="#validate">validate</a>( str, pos ); // returns Acceptable
|
|---|
| 86 | str = "678";
|
|---|
| 87 | v.<a href="#validate">validate</a>( str, pos ); // returns Acceptable
|
|---|
| 88 |
|
|---|
| 89 | str = "1234";
|
|---|
| 90 | v.<a href="#validate">validate</a>( str, pos ); // returns Invalid
|
|---|
| 91 | str = "-123";
|
|---|
| 92 | v.<a href="#validate">validate</a>( str, pos ); // returns Invalid
|
|---|
| 93 | str = "abc";
|
|---|
| 94 | v.<a href="#validate">validate</a>( str, pos ); // returns Invalid
|
|---|
| 95 | str = "12cm";
|
|---|
| 96 | v.<a href="#validate">validate</a>( str, pos ); // returns Invalid
|
|---|
| 97 | </pre>
|
|---|
| 98 |
|
|---|
| 99 | <p> The minimum and maximum values are set in one call with <a href="#setRange">setRange</a>()
|
|---|
| 100 | or individually with <a href="#setBottom">setBottom</a>() and <a href="#setTop">setTop</a>().
