Constructor & Destructor Documentation

KeyboardEvent()

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 119 of file keyboard_event.h.

References Alt, Ctrl, modifiers_, and Shift.

Member Function Documentation

getKeyCode()

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 155 of file keyboard_event.h.

References key_code_.

getKeySym()

const std::string & pcl::visualization::KeyboardEvent::getKeySym ( ) const
inline
Returns
name of the key that caused the event

Definition at line 161 of file keyboard_event.h.

References key_sym_.

isAltPressed()

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 137 of file keyboard_event.h.

References Alt, and modifiers_.

isCtrlPressed()

bool pcl::visualization::KeyboardEvent::isCtrlPressed ( ) const
inline
Returns
whether the ctrl was pressed at the time where this event was triggered

Definition at line 143 of file keyboard_event.h.

References Ctrl, and modifiers_.

isShiftPressed()

bool pcl::visualization::KeyboardEvent::isShiftPressed ( ) const
inline
Returns
whether the shift was pressed at the time where this event was triggered

Definition at line 149 of file keyboard_event.h.

References modifiers_, and Shift.

keyDown()

bool pcl::visualization::KeyboardEvent::keyDown ( ) const
inline
Returns
true if a key-press caused the event, false otherwise

Definition at line 167 of file keyboard_event.h.

References action_.

keyUp()

bool pcl::visualization::KeyboardEvent::keyUp ( ) const
inline
Returns
true if a key-release caused the event, false otherwise

Definition at line 173 of file keyboard_event.h.

References action_.
