DESCRIPTION

Xevie X Event Interception Extension (XEvIE) is designed for users who need to intercept all the Keyboard and Mouse events. The requirement for XEvIE is directly from GNOME Accessibility project. AT Accessibility API needs to have full keyboard/mouse control. XEvIE provides a set of API to allow AT Accessibility API to get and consume Keyboard/Mouse events.

FUNCTIONS

XevieQueryVersion The XevieQueryVersion function returns the major and minor protocol version numbers supported by the server. XevieQueryVersion returns True if success, otherwise, it returns False.

XevieStart The XevieStart function requests that the X server enable the XEvIE extension. Once XEvIE is successfully enabled, all the XevieSelectInput specified events will be sent to the client which has enabled XEvIE. If XKB or AccessX is enabled, the events that are sent to the XEvIE clients are XKB/AccessX processed (filtered) ones.

XevieSend Events are sent back to the X server through XevieSendEvent.

XevieEnd The XevieEnd function requests that the X server disables the XEvIE extension. Once XEvIE is disabled successfully, the X server stops sending events to the XEvIE client.

XevieSelectInput The XevieSelectInput function requests that the X server reports the keyboard and pointer events associated with the specified event mask. By default, X will report KeyPress, KeyRelease, ButtonPress, ButtonRelease and MotionNotify events.

SH RESTRICTIONS Xevie will remain upward compatible after the current 1.0 release.
