Title: OpenURL
| Old | New | Line | |
|---|---|---|---|
| 1 | + | ## Definition | |
| 2 | + | ||
| 3 | + | Unit: Lazarus **lclintf** | |
| 4 | + | ||
| 5 | + | ``` pascal | |
| 6 | + | function OpenURL(AURL: String): Boolean; | |
| 7 | + | ``` | |
| 8 | + | ||
| 9 | + | Official documentation: [OpenUrl](http://lazarus-ccr.sourceforge.net/docs/lcl/lclintf/openurl.html) | |
| 10 | + | ||
| 11 | + | ## Description | |
| 12 | + | ||
| 13 | + | `OpenUrl` opens a URL with the default/registered/preferred web browser as specified by the operating system. | |
| 14 | + | ||
| 15 | + | Spaces in URLs need to be encoded as %20; see [RFC1738](http://www.ietf.org/rfc/rfc1738.txt). When using the <file://> URI scheme, you should not encode spaces with %20. | |
| 16 | + | ||
| 17 | + | ## Warning | |
| 18 | + | ||
| 19 | + | On Windows with Lazarus versions older than revision r40490 (2013-03-06), opening a URL using the <file://> URI scheme (to open a local file) may fail if there are spaces in the filename. | |
| 20 | + | ||
| 21 | + | With those older Lazarus versions, you should enclose the entire string in double quotation marks, if you are on an NT platform. | |
| 22 | + | ||
| 23 | + | This is unfortunately system and browser dependant. Note: opening a <file://> URL with spaces on Win9x will probably fail if you enclose the URL in quotation marks (See [Issue \#21659](https://bugs.freepascal.org/view.php?id=21659)). | |
| 24 | + | ||
| 25 | + | On Windows it is preferable to not use `OpenUrl` with the <file://> URI scheme, but use [[opendocument|OpenDocument]] with the filename instead because of the above mentioned problems. | |
| 26 | + | ||
| 27 | + | ## Example | |
| 28 | + | ||
| 29 | + | ``` pascal | |
| 30 | + | uses | |
| 31 | + | ... | |
| 32 | + | lclintf | |
| 33 | + | ... | |
| 34 | + | OpenURL('https://wiki.lazarus.freepascal.org/'); | |
| 35 | + | ``` | |
| 36 | + | ||
