Mmm, perhaps I should have been more specific. I'd prefer sample code.
The documentation for NSView is not working for me and is not
providing the practical information I need; I'd prefer to see a set of
sample code that puts the concepts into action.
My program has a window which has a contentView that contains 4 or 5
equal sized subviews. They are arranged vertically in a column. Here's
some code from my NSWindow subclass, hope it helps.
- (void) windowSizeChanged
{
NSArray *allViews = [[self contentView] subviews];
NSEnumerator *views = [allViews objectEnumerator];
int i = [allViews count] - 1;
NSRect parentRect = [[self contentView] bounds];
float sizeHeight = parentRect.size.height / [allViews count];
float yPos = 0;
NSView *thisView;
[self disableFlushWindow];
while ( thisView = [views nextObject] )
{
// the first subview will always be positioned at the top at the
window titlebar
// as subviews are added they are positioned underneath, last one at
the bottom
yPos = i-- * sizeHeight;
NSPoint newPoint = NSMakePoint(
parentRect.origin.x , // use existing parentView left edge
parentRect.origin.y + yPos // make a new bottom edge for this view
);
NSRect newRect;
newRect.origin = newPoint;
newRect.size = NSMakeSize(
parentRect.size.width ,
sizeHeight
);
[thisView setFrame:newRect];
[thisView resetTrackingRects];
}
[self setViewsNeedDisplay:YES];
[self enableFlushWindow];
}
