Layout vs. Frame: X position of objects


  • Subject: Layout vs. Frame: X position of objects
  • From: Todd Heberlein <email@hidden>

When using the "Size & Position" information for an object to position it in a view, what is the difference between the "Layout" and "Frame" values in the pop-up button?  When should I use "Layout", and when should I use "Frame"?

When trying to layout objects, especially when trying to align them with the edge of a window, should I be using "Layout" when setting the X position and width?

Thanks,

Todd

--- Experiment ---

I took 5 objects in IB (3.2.6) and put them on a window, selected them all, and chose

	Layout -> Alignment -> Align Left Edges

Visually they all looked aligned, but when I checked the X position of these objects under "Size & Position", I got a range of values for the "Frame" (see below) but a consistent value of 100 for "Layout".

	100	NSScrollView (with NSTableView)
	100	NSView (custom view)
	97	NSBox
	94	NSButton
	93	NSTabView
