What's the easiest way to create a custom control that contains a matrix of 4 custom vertical sliders, like a mini graphic EQ? The sliders will not draw the slot, only the knob. First I started with a subclass of NSMatrix and a subclass of NSCell. No matter what I've tried, the cells always end up drawing at the wrong size, as if they were the cell for a simple text matrix, about 100 pixels wide and the height of a regular size text label. I create it thusly:
MyMatrix* blView = [[MyMatrix alloc] initWithFrame:NSMakeRect(100, 100, 200, 80) mode:NSTrackModeMatrix cellClass:[MyCell class] numberOfRows:1 numberOfColumns:4];
I've tried overriding all sorts of methods in the 2 subclasses; cellSize, cellFrameAtRow:column, even returning a cellSize of 10000,10000 as suggested in the docs for cells that aren't text or image cells.
