如何更改NSTableHeaderCell的字体大小 [英] How to change font size of NSTableHeaderCell

问题描述

我正在尝试在代码中更改NSTableView的字体大小，以允许用户根据自己的喜好更改它。
我成功地更改了每个NSTableCellView的字体大小，但未能通过页眉单元格来完成。

I am trying to change the font size of my NSTableView within my code to allow the user to change it to their liking. I was successful by changing the font size of each NSTableCellView but failed to do so by the header cells.

我试图这样做p>

I was trying to do it like this

let headerCell = NSTableHeaderCell()
let font = NSFont(name: "Arial", size: 22.0)
headerCell.stringValue = "firstname"
headerCell.font = font
customerTable.tableColumns[0].headerCell = headerCell

标题单元格的stringValue会相应设置，但大小不会更改。如何更改标题的字体大小？

The stringValue of the header cell will be set accordingly but the size does not change. How can I change the font size of my headers?

谢谢

推荐答案

您可以创建一个 NSTableHeaderCell 子类并实现要更改的属性。

You can create a NSTableHeaderCell subclass and implement the property you want to change.

在Objective-C中（我不擅长Swift）：

In Objective-C (I'm not good at Swift):

@implementation CustomTableHeaderCell

-(NSFont *)font {
    return [NSFont fontWithName:@"Arial" size:22];
}

// you can alse custom textColor
-(NSColor *)textColor {
    return [NSColor redColor];
}

@end

分配 CustomTableHeaderCell ：

CustomTableHeaderCell *headerCell = [[CustomTableHeaderCell alloc] init];
headerCell.stringValue = @"Header title";
self.tableView.tableColumns[0].headerCell = headerCell;

在Cocoa中，有很多事情您不能通过 cell.font = ... 来更改其样式，您需要创建一个subcalss。

In Cocoa, there are many things you can't change its style by cell.font = ..., you need to create a subcalss.
