Custom background colors for NSTableCellView

问题:

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?

回答1:

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.

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

@interface MyRowView : NSTableRowView

there you have:

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

e.g.

@implementation MyRowView

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

@end
