NSTableCellView的自定义背景色 [英] Custom background colors for NSTableCellView

问题描述

我正在尝试创建自定义NSTableCellView。我将NSTableCellView划分为子类，我需要具有自定义的背景颜色和突出显示/选择颜色。有办法吗？

I am trying to create a custom NSTableCellView. I subclassed NSTableCellView and I need to have a custom background color and highlight/selection color. Is there a way to do this?

推荐答案

背景以及选择由处理NSTableRowView 视图。它可以（部分地）被单元格覆盖，但这根本不是应该的。

the background as well as the selection is handled by the NSTableRowView view. It CAN (partly) be overwritten by the cell but that's not how it should be at all.

实现自定义行视图，并将其返回以供在行后面使用，您需要绘制

Implement a custom rowview and return that for use behind the row you need to draw

@interface MyRowView : NSTableRowView

您有：

• drawBackgroundInRect：


• drawDraggingDestinationFeedbackInRect：


• drawSelectionInRect：


• drawSeparatorInRect：

• drawBackgroundInRect:
• drawDraggingDestinationFeedbackInRect:
• drawSelectionInRect:
• drawSeparatorInRect:

例如

@implementation MyRowView

- (void)drawSelectionInRect:(NSRect)dirtyRect {
        [currentFill fillRect:dirtyRect inContext:[[NSGraphicsContext currentContext]graphicsPort]];
}

@end
