我正在以编程方式创建几个菜单项:
NSMenuItem* newItem = [[NSMenuItem alloc] initWithTitle:t action:s keyEquivalent:e];
[newItem setTarget:target];
[newItem setEnabled:YES];
[self addItem:newItem];
我想截断它们的内容(在中间):
一些真正很长的冠军--->一些rea ... title
我读过关于使用setLineBreakMode
方法的内容......但是如何?(我认为我做错了什么:-S)
答案 0 :(得分:4)
可能的解决方案是使用NSAttributedString和[NSMenuDelegate confinementRectForMenu:onScreen:screen];
confinementRectForMenu是设置所需的最大宽度所必需的
为了向您展示一个没有委托的示例,我展示了一个非常大字体的菜单项
NSMutableParagraphStyle *style = [[NSParagraphStyle defaultParagraphStyle]
mutableCopy];
[style setLineBreakMode:NSLineBreakByTruncatingMiddle];
NSDictionary* paragraphStyle = [[NSDictionary alloc] initWithObjectsAndKeys:
style, NSParagraphStyleAttributeName,
[NSFont fontWithName:@"Lucida Grande" size:43.0f],
NSFontAttributeName,
nil];
[style release];
NSString* title = @"long titlelong titlelong titlelong titlelong titlelong titlelong and another string titlelong titlelong title end";
NSAttributedString* str = [[[NSAttributedString alloc] initWithString:title attributes:paragraphStyle] autorelease];
NSMenuItem* newItem = [[NSMenuItem alloc] initWithTitle:title action:@selector(showWhitespaces:) keyEquivalent:@""];
[newItem setAttributedTitle:str];
[newItem setEnabled:YES];
[theMenu addItem:newItem];
