Scripting API - Add a signal for when a object was selected

[BlaXun]

For my tiled extension I added a tool that should only be available if the currently selected object is of a specific type. Unfortunately I can not enable/disable the tool because I don't have a signal / event that informs me that a object was selected/ deselected. I think it would be a good idea to throw such an event / signal that we extension-users could subscribe to.

Hmm, some signals are currently not documented. Among these is TileMap.selectedObjectsChanged, which is called when the TileMap.selectedObjects property changes:

tiled.activeAsset.selectedObjectsChanged.connect(() => tiled.log(tiled.activeAsset.selectedObjects))

I'll have to go through the currently available "Changed" signals and add them to the documentation.

Thats awesome! Thanks for sharing. Would be nice if the documentation could be updated :)

It would be nice to get a list of signals somewhere too. Currently they're just listed as variables in tiled, MapEditor, etc, but they're mixed together with other things, so it's not clear what's signals and what isn't. The old documentation handled this much better by listing signals separately from everything else, in the same area where it described how to connect to them.

I agree. Let's keep this in mind when we try to improve the format in general, based on generating Markdown instead (#3174).
