Method Detail

drag_start

public boolean drag_start(event evt,
                          java.lang.Object user_info)

Dispatch the start of a grow-drag to the object (intended to change its size). Returns true if the drag is accepted (and hence the event consumed). The event retains the original raw coordinate values (in the local coordinates of the object receiving the drag).

Parameters:

evt - the event "causing" the drag

user_info - the information object associated with the drag

Returns:

boolean indicating whether the input was consumed/accepted

drag_feedback

public boolean drag_feedback(event evt,
                             int cur_w,
                             int cur_h,
                             int start_w,
                             int start_h,
                             java.lang.Object user_info)

Dispatch movement during a grow-drag to the object (intended to change its size). Returns true if the drag is accepted (and hence the event consumed). The event retains the original raw coordinate values (in the local coordinates of the object receiving the drag). Both the original and new sizes are provided as well.

Parameters:

evt - the event "causing" the movement

cur_w - the current width of the object (based on movement from the first drag point)

cur_h - the current height of the object (based on movement from the first drag point)

start_w - the original width of the object

start_h - the original height of the object

user_info - the information object associated with the drag

Returns:

boolean indicating whether the input was consumed/accepted

drag_end

public boolean drag_end(event evt,
                        int cur_w,
                        int cur_h,
                        int start_w,
                        int start_h,
                        java.lang.Object user_info)

Dispatch movement during a grow-drag to the object (intended to change its size). Returns true if the drag is accepted (and hence the event consumed). The event retains the original raw coordinate values (in the local coordinates of the object receiving the drag). Both the original and new sizes are provided as well.

Parameters:

evt - the event "causing" the movement

cur_w - the current width of the object (based on movement from the first drag point)

cur_h - the current height of the object (based on movement from the first drag point)

start_w - the original width of the object

start_h - the original height of the object

user_info - the information object associated with the drag

Returns:

boolean indicating whether the input was consumed/accepted
