xtend thuban with a locator tool. |
| 10 |
|
| 11 |
Collect positions of mouse clicks (in map coordinates) in a text control. |
| 12 |
|
| 13 |
The tool was implemented in the need to collect some coordinates for some |
| 14 |
work (outside Thuban). The status bar display of the coordinates is quite |
| 15 |
transient (each mouse movement changes it) and cannot be copied. The tool let |
| 16 |
one simply collect the coordinates needed and copy them in one block later. |
