Detailed Description

A viewer that displays thumbnails (small versions of larger images).

Will only display objects derived from CanvasImage (?).

Constructor & Destructor Documentation

ThumbnailViewer::ThumbnailViewer (    )  [inline]
 

Constructor. 

00031 {
00032     doInit(64, 64, false);
00033 }

ThumbnailViewer::ThumbnailViewer (  int    width,
int    height,
boolean    fixedSize
)  [inline]
 

Constructor. 

00039 {
00040     doInit(width, height, fixedSize);
00041 }

Member Function Documentation

int ThumbnailViewer::addObject (  CanvasObject    obj )  [inline]
 

Overrides CanvasViewer interface.

Add a CanvasImage (?) to the viewer. Works correct only in case all images on the canvas have the same size (since it adjusts the zoom factor of the canvas).

Reimplemented from CanvasViewer. 

00050 {
00051     double objWidth  = obj.getWidth();
00052     double objHeight = obj.getHeight();
00053     double width = _visualizer.getViewportSize().width;
00054     double height = _visualizer.getViewportSize().height;
00055     double scale = Math.min(width / objWidth, height / objHeight);
00056     if (obj instanceof CanvasHxImage)
00057         ((CanvasHxImage) obj).setResolution(scale);
00058     int result = _visualizer.addObject(obj);
00059     if (_doZoom)
00060         doZoom(scale);
00061     return result;
00062 }

void ThumbnailViewer::setDoZoomOnAdd (  boolean    doZoom )  [inline]
 

if (doZoom) the thumbnail will adjust its zoom factor to make the object's visualization match the sizes of the viewer, otherwise the thumbnail will assume the sizes of the object are already adjusted to match the size of the viewer (so it does nothing) This will only affect future calls to addObject!
