How does the Blackberry Storm work?

Blackberry Storm Emulator - TouchGesture events not firing, how to get a Swipe to work?

• Been playing with the Storm Emulator and the 4.7 JDE, for the life of me I can't figure out how to fire gesture events in the emulator. Below is the touch event code for the RIM sample app EmbeddedMapDemo. It seems straightforward enough, but touchGesture.getEvent() == TouchGesture.SWIPE never seems to register to true. How can I register swipes in the Emulator? With my mouse I try doing left-click and drag but that does not seem to work. /** * @see Field#touchEvent(TouchEvent) */ protected boolean touchEvent(TouchEvent message) { boolean isConsumed = false; if(_mapField.isClicked()) { TouchGesture touchGesture = message.getGesture(); if (touchGesture != null) { // If the user has performed a swipe gesture we will // move the map accordingly. if (touchGesture.getEvent() == TouchGesture.SWIPE) { // Retrieve the swipe magnitude so we know how // far to move the map. int magnitude = touchGesture.getSwipeMagnitude(); // Move the map in the direction of the swipe. switch(touchGesture.getSwipeDirection()) { case TouchGesture.SWIPE_NORTH: _mapField.move(0, - magnitude); break; case TouchGesture.SWIPE_SOUTH: _mapField.move(0, magnitude); break; case TouchGesture.SWIPE_EAST: _mapField.move(- magnitude, 0); break; case TouchGesture.SWIPE_WEST: _mapField.move(magnitude, 0); break; } // We've consumed the touch event. isConsumed = true; } } } return isConsumed; }

• Answer:

  Pressing the left mouse button simulates clicking down the screen... the simulator (and also an actual Storm device, I think) won't fire TouchGesture events while you're clicking down on the screen. What you want to do is hold down the right mouse button and drag, since the right mouse button simulates a screen tap, without click. This way, you should be able to get TouchGestures to fire. It's a little hard to do a gesture on the simulator, you kinda have to move fast, but if you use the right mouse button you should be able to do it.
