Zoom In/Out using CTRL + MW

[CosminD]

Hello,

Is it possible to capture mouse wheel events similar to how we can capture keyboard events by providing a CefKeyboardHandler?
I'm trying to figure out how to zoom in and out using CTRL + MouseWheel, but I cannot capture the MW events.

Any help is greatly appreciated

You will need a low level mouse hook for that.

You might want also to throw the TrackMouseEvent/SetWinEventHook + EVENT_OBJECT_FOCUS and EVENT_OBJECT_SELECTION combo for detection.

Alternatively you can capture events in javascript and communicate with C++ via javascript bindings.

Why zooming with mouse wheel is not implemented by default?
Do we really have to use hooks or window subclass to handle it by ourselves? If so then why normal scroll is handled by cef/chromium?

"zooming with mouse" is implemented, I suppose, otherwise it will not work.
But the initial post says "capture mouse wheel events". "capture" is an entire differently beast.

No it's not. If it was this topic would not exist.

But the initial post says "capture mouse wheel events".

Capture in order to achive ability of changing browser zoom using "control" key with mouse wheel.
