|
|---|
| 61 |
|
|---|
| 62 |
|
|---|
| 63 | The QUriDrag class provides a drag object for a list of URI references.
|
|---|
| 64 | <p>
|
|---|
| 65 | <p> URIs are a useful way to refer to files that may be distributed
|
|---|
| 66 | across multiple machines. A URI will often refer to a file on a
|
|---|
| 67 | machine local to both the drag source and the drop target, so the
|
|---|
| 68 | URI can be equivalent to passing a file name but is more
|
|---|
| 69 | extensible.
|
|---|
| 70 | <p> Use URIs in Unicode form so that the user can comfortably edit and
|
|---|
| 71 | view them. For use in HTTP or other protocols, use the correctly
|
|---|
| 72 | escaped ASCII form.
|
|---|
| 73 | <p> You can convert a list of file names to file URIs using
|
|---|
| 74 | <a href="#setFileNames">setFileNames</a>(), or into human-readble form with <a href="#setUnicodeUris">setUnicodeUris</a>().
|
|---|
| 75 | <p> Static functions are provided to convert between filenames and
|
|---|
| 76 | URIs, e.g. <a href="#uriToLocalFile">uriToLocalFile</a>() and <a href="#localFileToUri">localFileToUri</a>(), and to and from
|
|---|
| 77 | human-readable form, e.g. <a href="#uriToUnicodeUri">uriToUnicodeUri</a>(), <a href="#unicodeUriToUri">unicodeUriToUri</a>().
|
|---|
| 78 | You can also decode URIs from a mimesource into a list with
|
|---|
| 79 | <a href="#decodeLocalFiles">decodeLocalFiles</a>() and <a href="#decodeToUnicodeUris">decodeToUnicodeUris</a>().
|
|---|
| 80 | <p>See also <a href="draganddrop.html">Drag And Drop Classes</a>.
