Detailed Description

A GUI plugin that displays a timer.

Control of this timer is managed via a topic that is ~/timer_control by default. The topic may be specified in the plugin's SDF. The topic receives string messages where:

"start" == start the timer
"stop" == stop the timer
"reset" == reset the timer

<plugin name="timer_plugin" filename="libTimerGUIPlugin.so"> <topic>~/my_timer_control</topic> <pos>pixel_x_pos pixel_y_pos</pos> <size>pixel_width pixel_height</size> <start_stop_button>visible</start_stop_button> <reset_button>visible</reset_button> </plugin>

Note that the size has to be large enough to fit all widgets.
