Scripting - Tools: Add a method to capure mouseWheel up/down #3244

None of the current tools use the wheel events, which are currently only used for scrolling and zooming. These functionalities also use most of the modifiers, so doing anything with wheel events in the tools would potentially intercept the user trying to scroll or zoom the view.

When adding support for this, probably tools should get the event first, and it would need to be somehow possible to know whether the tool has ignored the event, in which case it would still fall back to scrolling or zooming.

For now I'd suggest using a modifier along with regular mouse movement, to allow changing the radius.

Thanks for the answer. Are modifiers actually documented somewhere? I've checked the Scripting API documentation but could not find a clarification... maybe its in the "normal" documentation. I am not a regular user of Tiled, but am creating multiple custom tools for a project. I feel like I should know what "modifiers" refer too ^^, sry

The current online docs don't explain them yet, but this has been fixed in https://github.com/mapeditor/tiled/commit/3573815b85b2aa2266af9750d4347db1d14e81c2. The online documentation will be updated along with the Tiled 1.8 release.
