Rubberband
INHERITS FROM Object
DECLARED IN Rubberband.h
CLASS DESCRIPTION
Rubberband implements an interactive "rubberband rectangle" graphical selection tool. It uses the postscript functions in /usr/lib/NextStep/windowPackage.ps to achieve the same effect as the window manager does when resizing standard windows.
Possible bugs: Untested with non-default View and Window coordinate transformations.
INSTANCE VARIABLES
Inherited from Object Class isa;
Declared in Rubberband NXRect currentRect;
NXRect boundsRect;
id myView;
struct {
unsigned char pivot:1 ;
unsigned char inclusive:1 ;
unsigned char useBounds:1 ;
} flags;
currentRect The rubberband's rectangle, in window coordinatess
boundsRect The bounds constraining the rubberband rectangle, in window coordinates
myView View within which rubberband is drawn
flags.pivot Indicates stretch type.
flags.inclusive Indicates whether rectangle includes pixels under its sides.
flags.useBounds Indicates whether to use boundsRect.
METHOD TYPES
Initializing a new Rubberband - init
- initWithView :
Assigning a view - setView :
Stretching the Rubberband - doStretch :
Setting the parameters - setBounds :
- setCurrentRectToBounds
- setPivot :
- setInclusive:
Getting the parameters - currentRect :
- bounds :
Archiving none implemented
INSTANCE METHODS
bounds :
- bounds :(NXRect *)aRect
Returns in aRect the rectangle constraining the movement of the rubberband. Value is returned in aView coordinates and reflects value set by setBounds:. Returns self.
See also: - setBounds:
currentRect :
- currentRect :(NXRect *)aRect
Returns in aRect the current boundaries of the rubberband rectangle. Call this after calling doStretch to get the results of the user's action. Value is returned in aView coordinates and reflects value set by setInclusive:. Returns self.
See also: - setInclusive:
doStretch:
- doStretch :(NXEvent *)event
This is where the action is. While mouse is held down the rubberband will stretch. Call this when receiving the initial mouseDown: message, passing along event as the event of the initial mousedown. Returns self.
init:
- init:
Initializes the rubberband, but you must call setView: to complete the initialization. Returns self.
See also: - initWithView:, -setView:
initWithView:
- initWithView:aView
Preferred initialization method. Calls setView:. The rubberband's bounds is set to the bounds of aView. Returns self.
See also: - init:
setBounds :
- setBounds :(const NXRect *)aRect
Sets the rectangle within which movement of the rectangle is constrained. Turns on flags.useBounds. aRect should be given in myView coordinates. If aRect is NULL, turns off flags.useBounds. Returns self.
setCurrentRectToBounds
- setCurrentRectToBounds
Sets the boundsRect equal to currentRect. Turns on flags.useBounds. Returns self.
setPivot :
- (int) setPivot :(int)pivot
Sets the way in which the rubberband stretches as the mouse is moved. Can be either:
RB_CORNER : point of initial mouse click defines one corner of rubberband.
RB_CENTER : point of initial mouse click defines center of rubberband.
Returns previous pivot.
setInclusive :
- (BOOL) setInclusive :(BOOL)onoff
Set whether rectangle returned by currentRect: includes pixels under the rubberband sides. Returns previous value.
See also: - currentRect:
setView:
- setView: aView
Makes aView the view into which the rubberband will be drawn. The rubberband's bounds is set to the bounds aView. Returns previous view.
