Hello Carter.
Right now I can't remember the name of the example.
Its a little tricky but its do-able.
your MO subclass must do something like:
-(NSDictionary *)userDictionary{
return [self dictionaryWithValuesForKeys:[NSArray
arrayWithObjects:@"firstName",@"lastName",@"avatar",@"title",nil]];
}
+(NSSet *)keyPathsForValuesAffectingUserDictionary{
return [NSSet
setWithObjects:@"firstName",@"lastName",@"avatar",@"title",nil];
}
which the right properties.
then in the xib bind the value of the tablecolum to
arrangedObjects.userDictionary.
then subclass NSCell, on the awakeFromNib of the controller that contains the
tableview tell the TableColum to set its dataCell as the instance of my custom
cell, (of course I have to initialize my cell before that particular line).
then in my cell what I do is:
//====================================================================================================================================================
//Draw the cell that contains the name of the user andits picutre
//This methods tales the objectValue which is a NSDictionary, all this is done
bia bindings,
//the use entoty has a property NSDictionary keysDictionary which will return
all the keys of its propertioes with its corresponding values see @ User.m
//====================================================================================================================================================
-(void)drawWithFrame:(NSRect)cellFrame inView:(NSView *)controlView{
NSDictionary * cellValues = [self objectValue];
NSString * firstName = [cellValues valueForKey:@"firstName"];
NSString * lastName = [cellValues valueForKey:@"lastName"];
NSString * completeName = [NSString stringWithFormat:@"%@
%@",firstName,lastName];
NSPoint textPoint;
NSDictionary *textAttributes;
NSColor * fontColor;
fontColor = [self isHighlighted]?[NSColor whiteColor]:[NSColor
blackColor];
textAttributes = [NSDictionary dictionaryWithObjectsAndKeys: fontColor,
NSForegroundColorAttributeName, [NSFont fontWithName:@"Optima"
size:(CGFloat)13.0], NSFontAttributeName, nil];
NSSize nameSize = [completeName sizeWithAttributes:textAttributes];
textPoint.x = cellFrame.origin.x + 5.0f;
textPoint.y = cellFrame.origin.y +(cellFrame.size.height -
nameSize.height)/2.0f - 5.0f ;
NSRect rectOfDraw = NSMakeRect(textPoint.x,
textPoint.y,cellFrame.size.width - 50.0f,nameSize.height);
[completeName drawWithRect:rectOfDraw
options:NSStringDrawingTruncatesLastVisibleLine|NSStringDrawingUsesLineFragmentOrigin
attributes:textAttributes];
//Getting the Avatr Value
NSData * avatar = [cellValues valueForKey:@"avatar"];
NSImage * avatarImage = [[[NSImage alloc] initWithData:avatar]
autorelease];//[NSImage imageNamed:@"NoAvatar"];
[[NSGraphicsContext currentContext] saveGraphicsState];
CGFloat yOffset = cellFrame.origin.y;
//Checking if the controll view its flipped or no
//Most probably it is.
//then create an affine tarsnfor and translate its coordinates
if ([controlView isFlipped]) {
NSAffineTransform* xform = [NSAffineTransform transform];
[xform translateXBy:0.0 yBy: cellFrame.size.height];
[xform scaleXBy:1.0 yBy:-1.0];
[xform concat];
yOffset = 0-cellFrame.origin.y;
}
//Create and interpolation
//medium its ok, due we don't need to show a high resolutiuon thumbnail
NSImageInterpolation interpolation = [[NSGraphicsContext
currentContext] imageInterpolation];
[[NSGraphicsContext currentContext] setImageInterpolation:
NSImageInterpolationMedium];
//configure the image drawrect and size and pritn in on screen
if(avatarImage != nil){
NSRect imageRect ;
imageRect = NSZeroRect;
imageRect.size = [avatarImage size];
NSRect drawingRect;
drawingRect.origin.x = cellFrame.size.width - 40.0f;
drawingRect.origin.y = yOffset + 2.0;
drawingRect.size = NSMakeSize(37.0f, 37.0f);
[avatarImage drawInRect:drawingRect
fromRect:imageRect
operation:NSCompositeSourceOver
fraction:0.9];
}
[[NSGraphicsContext currentContext] setImageInterpolation:
interpolation];
[[NSGraphicsContext currentContext] restoreGraphicsState];
}
basically is jut taking the values from the cell objectvalue which is a
dictionary and then is just set up of the things inside. So it displays
correctly the name, the last name and the image of the user, in my case.
Note that this doesn't allow to edit the data inside the cell, for that you
will need not to draw the strings but set another cell with the name, or
something like that, im not sure.
I hope it helps
