pcl::visualization::KeyboardEvent::KeyboardEvent ( bool  action, const std::string &  key_sym, unsigned char  key, bool  alt, bool  ctrl, bool  shift  )

inline

Constructor.

Parameters

[in]	action	true for key was pressed, false for released
[in]	key_sym	the key-name that caused the action
[in]	key	the key code that caused the action
[in]	alt	whether the alt key was pressed at the time where this event was triggered
[in]	ctrl	whether the ctrl was pressed at the time where this event was triggered
[in]	shift	whether the shift was pressed at the time where this event was triggered

Definition at line 120 of file keyboard_event.h.

Member Function Documentation

unsigned char pcl::visualization::KeyboardEvent::getKeyCode ( ) const

inline

Returns

the ASCII Code of the key that caused the event. If 0, then it was a special key, like ALT, F1, F2,... PgUp etc. Then the name of the key is in the keysym field.

Definition at line 156 of file keyboard_event.h.

const std::string & pcl::visualization::KeyboardEvent::getKeySym ( ) const

inline

Returns

name of the key that caused the event

Definition at line 162 of file keyboard_event.h.

bool pcl::visualization::KeyboardEvent::isAltPressed ( ) const

inline

Returns

whether the alt key was pressed at the time where this event was triggered

Definition at line 138 of file keyboard_event.h.

bool pcl::visualization::KeyboardEvent::isCtrlPressed ( ) const

inline

bool pcl::visualization::KeyboardEvent::isShiftPressed ( ) const

inline

Returns

whether the shift was pressed at the time where this event was triggered

Definition at line 150 of file keyboard_event.h.

bool pcl::visualization::KeyboardEvent::keyDown ( ) const

inline

Returns

true if a key-press caused the event, false otherwise

Definition at line 168 of file keyboard_event.h.

bool pcl::visualization::KeyboardEvent::keyUp ( ) const

inline
