Data:

SCREEN_SENSITIVITY_MASK_ALWAYS: Pointer and touch events are always forwarded to the window's context if they interect with the window - regardless of transparency.; The window receives keyboard, gamepad, joystick events if it has input focus. Raising a window, pointer or multi-touch release event in that window will cause it to acquire input focus.

SCREEN_SENSITIVITY_MASK_NEVER: The window never receives pointer or multi-touch events.; The window never acquires input focus, even after it has been raised. The window will only receive input events that are directly injected into it from outside sources.

SCREEN_SENSITIVITY_MASK_NO_FOCUS: Pointer and touch events are forwarded to the window's context if they intersect the window and are in an area of the window that is not fully transparent.; The window does not acquire input focus after being raised or after a pointer or multi-touch release event occurs. Therefore, the window will not receive keyboard, gamepad, or joystick input unless it is sent directly into the window from an outside source.

SCREEN_SENSITIVITY_MASK_FULLSCREEN: Pointer and touch events are forwarded to the window's context no matter where they are on the screen.; The window is considered full screen for the purposes of input hit tests. Transparency is ignored. The window will receive keyboard, gamepad, and joystick events as long as the window is visible.

SCREEN_SENSITIVITY_MASK_CONTINUE: Windows underneath this window can receive pointer or multi-touch events even if this window has input focus.

SCREEN_SENSITIVITY_MASK_STOP: The window never receives pointer or multi-touch events.; The window never acquires input focus, even after it has been raised. The window will only receive input events that are directly injected into it from outside sources.

SCREEN_SENSITIVITY_MASK_POINTER_BRUSH: The window receives pointer events, even in areas of transparency, if the source coordinates of the event are within the brush clip rectangle.; This mode supercedes SCREEN_SENSITIVITY_MASK_NEVER. The windowing system also draws brush strokes based on the pointer events directly onto the screen and the window buffer.

SCREEN_SENSITIVITY_MASK_FINGER_BRUSH: The window receives multi-touch events with a finger contact type, even in areas of transparency, if the source coordinates of the event are within the brush clip rectangle.; This mode supercedes SCREEN_SENSITIVITY_MASK_NEVER. The windowing system also draws brush strokes based on the touch events directly onto the screen and the window buffer. Multiple contacts will cause multiple brush strokes to be drawn.

SCREEN_SENSITIVITY_MASK_STYLUS_BRUSH: The window receives multi-touch events with a stylus contact type, even in areas of transparency, if the source coordinates of the event are within the brush clip rectangle.; This mode supercedes SCREEN_SENSITIVITY_MASK_NEVER. The windowing system also draws brush strokes based on the touch events directly onto the screen and the window buffer. Multiple contacts will cause multiple brush strokes to be drawn.

SCREEN_SENSITIVITY_MASK_OVERDRIVE: Setting this bit causes the system to go into overdrive when the window gets an input event.; The effect of this sensitivity mask depends on the power management algorithms in place and on the platform in general.

SCREEN_SENSITIVITY_MASK_CLIPPED: The window receives touch and point data only when the position is within the bounds of the window.; If a pointer drag operation or a touch and move sequence leaves the window, the window will receive an input control notification that the event has left the bounds of the window and will not receive the subsequent events until the next touch or button press, or when the events re-enter the window again. Note that re-entry will only occur if the event leaves a window that also has clipping enabled on its sensitivity mask.

Library:

libscreen (For the qcc command, use the -l screen option to link against this library)

Description:

These masks are intended to be combined in a single integer bitmask representing combinations of desired senstivites to be applied to a window.
