I have noticed that Omni Outliner has the very tasty feature of allowing a subview to collapse on double click of the splitter. Does anyone have a code snippet which does this? Or perhaps know of an open source app which does this? Im guessing I need to overide mouse down or something, but thats about all this n00b knows.

heres what I came up with. the last two methods, - (float)fraction; and - (void)setFraction:(float)newFract; I found in OmniFrameworks.



@implementation lokiSplitViewHorizontal


- (void) mouseDown: (NSEvent *) theEvent {
if ([theEvent clickCount]==2) {
if (!(NSPointInRect([self convertPoint:[theEvent locationInWindow] fromView:nil], [[[self subviews] objectAtIndex:(0 || 1)] frame])) ) {
if ([[[self subviews] objectAtIndex:0] frame].size.height) {
theOldSize = [self fraction];
[self setFraction:1.0];
} else [self setFraction:(theOldSize == nil) ? .6 : theOldSize];
}
} else [super mouseDown:theEvent];
}

- (float)fraction {
NSRect topFrame, bottomFrame;

if ([[self subviews] count] < 2)
return 0.0;

topFrame = [[[self subviews] objectAtIndex:0] frame];
bottomFrame = [[[self subviews] objectAtIndex:1] frame];
return bottomFrame.size.height / (bottomFrame.size.height + topFrame.size.height);
}

- (void)setFraction:(float)newFract {
NSRect topFrame, bottomFrame;
NSView *topSubView;
NSView *bottomSubView;
float totalHeight;

if ([[self subviews] count] < 2)
return;

topSubView = [[self subviews] objectAtIndex:0];
bottomSubView = [[self subviews] objectAtIndex:1];
topFrame = [topSubView frame];
bottomFrame = [bottomSubView frame];
totalHeight = bottomFrame.size.height + topFrame.size.height;
bottomFrame.size.height = newFract * totalHeight;
topFrame.size.height = totalHeight - bottomFrame.size.height;
[topSubView setFrame:topFrame];
[bottomSubView setFrame:bottomFrame];
[self adjustSubviews];
[self setNeedsDisplay: YES];
}

@end


Anyone see any ways to make this mo' better? =)

Ive discovered a problem with my subclass of NSSpliView. Inside one of my subViews resides a tableView. Everything collapses and uncollapses nicely and this table view resizes correctly but, the scrollBar track is not changing length to match the tableView. I can cause it to redraw itself by resizing the window. How can I fix this?

Whenever you modify (move, resize, add/remove views, etc.) a splitview you have to call -adjustSubviews afterwards.

It's not exactly documented but it's come up a lot. If that's not your problem, well..I tried!
