| This example creates a folder on Window desktop with subfolders "Component One", "Component Two", etc. according to changes you made on the components page.
| |
| | |
| Compile this example and run it for multiple times each time changing options on the components page to see the results.
| |
| | |
| Please mail me to ts2001@hotbox.ru if you know how to improve this.
| |
| | |
| How to use this in your installer:
| |
| # Copy and paste Add/Remove system macros to the beginning of your script or to include file.
| |
| # Copy and paste Add/Remove callback functions right before uninstall section. Ensure you specified section index output constants in Section commands for each optional section.
| |
| # List your optional sections in the SectionList macro. Use following format for each section (replace section_index with the constant name you specified in Section command):<highlight-nsis> !insertmacro "${MacroName}" "section_index"</highlight-nsis>
| |
| # Write Remove_${section_index} macro after each optional section. This macro must describe section deletion.
| |
| | |
| Here is code of example installer implementing add/remove functionality:
