The IKImageBrowserCell class is used to display a cell conforming to the IKImageBrowserItem Protocol protocol in an IKImageBrowserView.
Returns the current cell state of the receiver.
- (IKImageBrowserCellState)cellState
The current state of the cell. See “IKImageBrowserCellState” for possible values.
The IKImageBrowserView creates thumbnails asynchronously. This method returns the current state.
IKImageBrowserCell.hReturns the receiver’s frame rectangle, which defines its position in its IKImageBrowserView.
- (NSRect)frame
The coordinates of the frame, in the IKImageBrowserView coordinate space.
Subclasses should not override this method.
IKImageBrowserCell.hReturns the position of the cell’s image in the frame.
- (NSImageAlignment)imageAlignment
The alignment of the image. See NSImageAlignment for possible values.
Subclasses can override this method to customize the image alignment.
The image frame will be computed automatically from the image container frame by taking in account the image alignment and the image aspect ratio.
IKImageBrowserCell.hReturns the view the receiver uses to display the cell.
- (IKImageBrowserView *)imageBrowserView
The browser view containing the cell.
Subclasses should not override this method.
IKImageBrowserCell.hReturns the receiver’s image container frame rectangle, which defines the position of the container of the thumbnail.
- (NSRect)imageContainerFrame
The coordinates of image container frame, in the IKImageBrowserView coordinate space.
The image frame is computed automatically from the image container frame by taking in account the image alignment and the image aspect ratio.
Subclasses can override this method to customize the position of the thumbnail container.
IKImageBrowserCell.hReturns the receiver’s image frame rectangle, which defines the position of the thumbnail in its IKImageBrowserView.
- (NSRect)imageFrame
The coordinates of the frame, in the IKImageBrowserView coordinate space.
It is the developer’s responsibility to compute the imageFrame such that it lies entirely within the cell’s frame rectangle.
Subclasses can override this method to customize the position of the thumbnail.
IKImageBrowserCell.hReturns the index of the receiver’s represented object in the datasource.
- (NSUInteger)indexOfRepresentedItem
The index of the represented object in the datasource.
Subclasses should not override this method.
IKImageBrowserCell.hReturns whether the cell is selected.
- (BOOL)isSelected
YES if the cell is selected, otherwise NO.
Subclasses should not override this method.
IKImageBrowserCell.hReturns a layer for the specified position.
- (CALayer *)layerForType:(NSString *)type
A string representing the layer location. See “Cell Layer Positions” for possible values.
The CALayer to display in the specified position.
Subclasses can override this method to add a Core Animation layer to the cell
IKImageBrowserCell.hReturns the opacity of the receiver.
- (CGFloat)opacity
The cell’s opacity.
Possible values are between 0.0 (transparent) and 1.0 (opaque).
Subclasses can override this method to customize the opacity of the cell.
IKImageBrowserCell.hReturns the receiver’s represented object.
- (id)representedItem
The item represented by the cell.
Subclasses should not override this method.
IKImageBrowserCell.hReturns the receiver’s selection frame rectangle, which defines the position of the selection rectangle in its IKImageBrowserView.
- (NSRect)selectionFrame
The cells selection frame, in the IKImageBrowserView coordinate space.
Subclasses can override this method to customize the position of the selection frame.
IKImageBrowserCell.hReturns the receiver’s subtitle frame rectangle.
- (NSRect)subtitleFrame
The coordinates of the subtitle frame, in the IKImageBrowserView coordinate space.
It is the developer’s responsibility to compute the subtitleFrame such that it lies entirely within the cell’s frame rectangle.
Subclasses can override this method to customize the position of the subtitle.
IKImageBrowserCell.hReturns the receiver’s title frame rectangle.
- (NSRect)titleFrame
The coordinates of the title frame, in the IKImageBrowserView coordinate space.
It is the developer’s responsibility to compute the titleFrame such that it lies entirely within the cell’s frame rectangle.
Subclasses can override this method to customize the position of the title.
IKImageBrowserCell.hThe possible states for the browser cell. These values are used by the cellState method.
typedef enum{
IKImageStateNoImage=0,
IKImageStateInvalid,
IKImageStateReady,
} IKImageBrowserCellState;
IKImageStateNoImageReturned until a thumbnail has been created from the represented object.
Available in Mac OS X v10.6 and later.
Declared in IKImageBrowserCell.h.
IKImageStateInvalidThe thumbnail is invalid. For example, an unsupported image is provided.
Available in Mac OS X v10.6 and later.
Declared in IKImageBrowserCell.h.
IKImageStateReadyThe receiver’s represented object has been set and the cell is ready to display.
Available in Mac OS X v10.6 and later.
Declared in IKImageBrowserCell.h.
Optional positioning of additional layers displayed with the cell. Used by the layerForType: method.
