No. You're missing my point.
You have -viewWillDraw, an override point at which you know your view

asked to draw rects that intersect with your visible rect[1]. Just query
-getRectsBeingDrawn:count: from within -drawRect, and render your

Well, that's essentially what I'm doing, by only drawing in the dirtyRect
(yeah, I know that's just one big union of the results of getRectsBeingDrawn,
but essentially).
Right, but you're missing the crucial step of caching this drawing.
I'm obviously not being clear. Here's some pseudocode:
- setFrameSize:(NSSize)size {
[super setFrameSize:size];
[self discardEntireWaveformCache];
}
- setNeedsDisplayInRect:(NSRect)rect {
[super setNeedsDisplayInRect:rect];
[self invalidateWaveformCacheForReft:rect];
}
- viewWillDraw {
if ([self waveformCacheDiscarded]) {
[self allocateWaveformCacheOfSize:self.bounds.size];
}
for (NSRect rect in [self getRectsBeingDrawn]) {
if (!([self waveformCacheIsValidForRect:rect])) {
[self cacheWaveformForRect:rect];
}
}
}
- drawRect:(NSRect)unused {
for (NSRect rect in [self getRectsBeingDrawn]) {
[self drawWaveformCacheForRect:rect];
}
}
Implementation of the waveform cache, as well as more sophisticated techniques
like background rendering the waveform cache are left as exercises to the
reader.

dragging NSTableColumn to another table
I have a view-based table with a single row. I want to be able to drag columns to another table and (within the same table for reordering). For this, I can't use the standard NSTableView column reordering. I've already subclassed NSTableHeaderCell for custom drawing. Does anyone know the steps to allow custom dragging of a table column to another table? Is this possible? If I was dealing with an NSView subclass, I think this would be straightforward. I want to show the entire column (header + row) when dragging. I believe that the dragging implementation could go in my NSTableHeaderCell subclass, but I'm not sure how to get started.

Custom drawn window like Game Center
Hi. I'm wondering what would be the most correct way to create an app looking like Game Center (with the title drawn with white font, and custom background images for the titlebar and the client area, but to make it behave completely like a normal OS X application). Is it possible to make such an app for several systems (Snow Leopard, Lion, Mountain Lion), looking natively?

If I was dealing with an NSView subclass, I think this would be straightforward. I want to show the entire column (header + row) when dragging. I believe that the dragging implementation could go in my NSTableHeaderCell subclass, but I'm not sure how to get started. It's definitely possible, but you'll have to do a bit of subclassing. I suspect you're going to need to subclass the overall NSTableView so that you can receive a private drag type and do the necessary graphics work as part of NSDraggingDestination. There are two parts to a drag - the drag source and the drag destination. The source can be your custom table header cell, but the destination is probably going to have to be a subclass of the table view itself. The two parts can be programmed fairly independently, once you've settled on how they are going to communicate in terms of the column data you pass from to the other. Having subclassed your table header cell, kicking off the drag shouldn't be too hard - just handle the mouseDown or mouseDragged and capture an image of the column as the drag image. NSView's method for capturing part of a view to a bitmap rep is invaluable here. Declare a private drag type and use whatever data makes sense to pass the column content through the drag pasteboard mechanism - you might not need to actually transfer any data, you could just store enough info in shared variables (e.g. just make a note of the source column somewhere) that your custom table class can access - as it's all private there's no need to consider dragging to other apps or supporting standard data formats. The hardest part as I see it is in receiving the drag. Your custom table class will register for the private drag type, and implement NSDraggingDestination methods to do whatever is needed to provide feedback and validation of the drag. You will need for example to highlight the place where the column can be dropped, and maybe animate moving other columns apart to make room. You'll want to pass anything else up to super's implementation to continue supporting all the standard dragging that the table can handle. On a drop, you just need to remove the column from the source, use the private data to recreate it at the destination and insert it into the table view. --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
