|
|
* In order to find tk.tcl during initialization, the following script
|
| 17 |
|
|
* is invoked by Tk_Init(). It looks in several different directories:
|
| 18 |
|
|
*
|
| 19 |
|
|
* $tk_library - can specify a primary location, if set
|
| 20 |
|
|
* no other locations will be checked
|
| 21 |
|
|
*
|
| 22 |
|
|
* $env(TK_LIBRARY) - highest priority so user can always override
|
| 23 |
|
|
* the search path unless the application has
|
| 24 |
|
|
* specified an exact directory above
|
| 25 |
|
|
*
|
| 26 |
|
|
* $tcl_library/../tk$tk_version
|
| 27 |
|
|
* - look relative to init.tcl in an installed
|
| 28 |
|
|
* lib directory (e.g. /usr/local)
|
| 29 |
|
|
*
|
| 30 |
|
|
* <executable directory>/../lib/tk$tk_version
|
| 31 |
|
|
* - look for a lib/tk<ver> in a sibling of
|
| 32 |
|
|
* the bin directory (e.g. /usr/local)
|
| 33 |
|
|
*
|
| 34 |
|
|
* <executable directory>/../library
|
| 35 |
|
|
* - look in Tk build directory
|
| 36 |
|
|
*
|
| 37 |
|
|
* <executable directory>/../../tk$tk_patchLevel/library
|
| 38 |
|
|
* - look for Tk build directory relative
|
| 39 |
|
|
* to a parallel build directory
|
| 40 |
|
|
*
|
| 41 |
|
|
* The first directory on this path that contains a valid tk.tcl script
|
| 42 |
|
|
* will be set ast the value of tk_library.
|
| 43 |
|
|
*
|
| 44 |
|
|
* Note that this entire search mechanism can be bypassed by defining an
|
| 45 |
|
|
* alternate tkInit procedure before calling Tk_Init().
