Right mouse button displayed to work to move backward in jelly bean

Question

We changed a piece of code in `framework / base / services / input / inputreader.cpp to right-click to move backward.

case BTN_RIGHT: mBtnRight = rawEvent->value; break; 

to

 case BTN_RIGHT: mBtnBack = rawEvent->value; break; 

It receives all mouse events. When I click the right mouse button, it accepts motion events, as well as key events. But he cannot send key events.

His mistake:

Reason: Waiting because the focused window has not finished processing the input events that were previously delivered to it. D/InputDispatcher( 1229): findFocusedWindow finished: injectionResult=-1, timeSpentWaitingForApplication=0.0ms

Is this a mistake in jelly bean?

Answer 1

To make Right_click work like a back button, make the following changes. he works for me.

  in function reset(InputDevice* device) { replace mBtnRight = device->isKeyPressed(BTN_RIGHT); line to mBtnBack = device->isKeyPressed(BTN_RIGHT); and in function process(const RawEvent* rawEvent) { remove 3 lines case BTN_RIGHT: mBtnRight = rawEvent->value; break; and Add "case BTN_RIGHT:" before case BTN_BACK:" as shown below case BTN_RIGHT: case BTN_BACK: mBtnBack = rawEvent->value; break; 

/ * It all works for me. * /
