在NSTableView的同一单元格中显示图标和文本 [英] Display icon and text in same cell of NSTableView

问题描述

我想在表格视图的单个单元格中的文本项旁边显示一个图标。

I would like to display an icon next to a text item in an single cell of a table view.

我想要实现的一个示例是应用程序

An example of what I want to achieve is the application list in System Preferences -> User Accounts -> Login Items.

有什么好办法？

推荐答案

这里有一个很好的例子： http：/ /www.cocoadev.com/index.pl?IconAndTextInTableCell 您制作自己的自定义NSCell，既绘制图​​像和文本

There is a good example here how to do it: http://www.cocoadev.com/index.pl?IconAndTextInTableCell You make your own custom NSCell that both draws a image and text

@interface IconCell : NSCell 
{
NSArray * cellValue;
}
- (void)setObjectValue:(id <NSCopying>)object;
- (void)drawInteriorWithFrame:(NSRect)cellFrame inView:(NSView *)controlView;

@implementation IconCell

- (void)drawInteriorWithFrame:(NSRect)cellFrame inView:(NSView *)controlView
{
NSDictionary * textAttributes =
    [NSDictionary dictionaryWithObjectsAndKeys:[NSFont 
userFontOfSize:10.0],NSFontAttributeName, nil];
NSPoint cellPoint = cellFrame.origin;

[controlView lockFocus];

[[cellValue objectAtIndex:1] compositeToPoint:NSMakePoint(cellPoint.x+2,
cellPoint.y+14) operation:NSCompositeSourceOver];
[[cellValue objectAtIndex:0] drawAtPoint:NSMakePoint(cellPoint.x+18,
cellPoint.y) withAttributes:textAttributes];

[controlView unlockFocus];
}

- (void)setObjectValue:(id <NSCopying>)object
{
   cellValue = (NSArray *)object;
}
@end
