Bug 27043 – Mouse-dragged events are not generated for right & middle buttons for NPAPI plugins

• Status: RESOLVED
• Resolution: WONTFIX
• Component: Plug-ins

[Dan Webb]

When in Cocoa events mode, NPAPI does not generate mouse-dragged events for the right & middle mouse buttons.  Left button mouse-dragged events are working fine.

The Google Earth plugin UI depends heavily on all three mouse buttons, so this is a big deal for us.  Right-button-drag is used for zooming in/out, and middle-button-drag is for tilting & rotating.

Could it be that the rightMouseDragged method is not implemented?  See <http://trac.webkit.org/browser/trunk/WebKit/mac/Plugins/WebNetscapePluginView.mm>.

Fixes middlemouse and rightmouse drag events.

I have thoroughly enjoyed fixing this bug.

Fixes middlemouse and rightmouse drag events.

Basically looks good, but you probably also want to add -[WebBaseNetscapePluginView otherMouseDragged:NSEvent*] and you also need to add tests cases for it

Hi Oliver,

I was looking at adding a test but the eventSender only MouseDown/MouseUp and dragMode.  There doesn't seem to be a way to simulate middle/right mouse clicks in the current framework.

Let me look at the otherMouseDragged, I made a change somewhere else (was it dragMouse?) that fixed this, because the event is handled by a view higher up the chain.  But only leftMouse drags were being passed down to the lower levels.

NPAPI support has been removed from Safari 14 onward and also not supported in WebkitGTK builds.

Can we close this as "RESOLVED WONTFIX"? Thanks!
