events

Create a window manager connection to Screen and dump the events received as output to the console.

Syntax:

events [-pos=x,y]
       [-size=widthxheight]

Runs on:

QNX Neutrino

Options:

-pos=x,y
Sets the x,y coordinates to show the window on the display. The default coordinate of 0,0 is used if this option isn't specified.
-size=widthxheight
Sets the size of the window The default size is 64x64 if this option isn't specified.

Description:

The events binary is used to demonstrate how events are handled. The output from this binary also includes notifications when a window is created or destroyed. The window properties are dumped when a WINDOW_CREATE_EVENT is received. In the window created on the display, input events, such as from a pointer or keyboard, are received.

To run events:
  1. Ensure that screen is running.
  2. Run events from a shell.
If you have a keyboard connected to your target, you can use the Esc key to exit this application at any time.

Examples:

Run events in the background: 
# events& -pos=10,10 -size=100x100 &

SCREEN_EVENT_PROPERTY(window=0x00110040, pname=84)
SCREEN_EVENT_PROPERTY(window=0x00000000, pname=84)
SCREEN_EVENT_PROPERTY(window=0x00110040, pname=154)
SCREEN_EVENT_PROPERTY(window=0x00110040, pname=154)
If you run events, then run and then slay another application that uses screen, such as gles2-gears, you should see various events. For example:
