Constructor & Destructor Documentation

SimpleFrameNavigator::SimpleFrameNavigator (  FrameNavigatorUser    u,
int    curFrame,
int    minFrame,
int    maxFrame,
int    scrollType
)  [inline]
 

Construct a SimpleFrameNavigator.

scrollType indicates whether the GUI uses a ScrollBar (scrollType == 1) or a Slider (scrollType == 2). 

00036 {
00037     doInit(u, curFrame, minFrame, maxFrame, scrollType);
00038 }

SimpleFrameNavigator::SimpleFrameNavigator (  int    scrollType )  [inline]
  

00041 {
00042     doInit(null, 0, 0, 0, scrollType);
00043 }

SimpleFrameNavigator::SimpleFrameNavigator (    )  [inline]
  

00046 {
00047     doInit(null, 0, 0, 0, SCROLL_BAR);
00048 }

Member Function Documentation

double SimpleFrameNavigator::getCurrentFrame (    )  [inline]
 

Get the current frame. 

00053 {
00054     return _curFrame;
00055 }

void SimpleFrameNavigator::setUser (  FrameNavigatorUser    u )  [inline]
 

Reimplemented from FrameNavigator. 

00058 {
00059     _user = u;
00060 }

void SimpleFrameNavigator::setCurrentFrame (  int    newFrame )  [inline]
 

Update the GUI to reflect the given status.

Will not call the _user (it is assumed that the _user does it).

Reimplemented from FrameNavigator. 

00066 {
00067     if (newFrame == _curFrame)
00068         return;

void SimpleFrameNavigator::setNumberOfFrames (  int    maxFrame )  [inline]
 

Reimplemented from FrameNavigator. 

00073 {
00074     updateStatus(0, 0, maxFrame);
00075 }

void SimpleFrameNavigator::updateStatus (  int    curFrame,
int    minFrame,
int    maxFrame
)  [inline]
 

Update the GUI to reflect the given status.

Will not call the _user (it is assumed that the _user does it). 

00081 {
00082     _minFrame = minFrame;
00083     _maxFrame = maxFrame;
00084     if (_sb != null) {

00092     changeFrame(curFrame);
00093 }

void SimpleFrameNavigator::actionPerformed (  ActionEvent    e )  [inline]
 

Implementation of ActionListener. 

00099 {
00100     if (e.getSource() == _frameField) {

00102             return;
00103         String s = _frameField.getText();
00104         changeFrame(java.lang.Integer.valueOf(s).intValue());
00105         if(_user != null) _user.handleFrameChanged(_curFrame);
00106     }
00107 }

00126     if (_updatingFrame) // check whether we did this ourself
00127         return;
00128     int value = _slider.getValue();
00129     changeFrame(value);
00130     if(_user != null) _user.handleFrameChanged(_curFrame);
00131 }
