I'm just learning the cocoa api's and have a couple of newbie
questions that I did not readily find in the docs:
Question 1:
- I have a window, with a custom view. I get the window from a nib
and can draw into the view, all good so far. The question is this,
it's not until runtime that I know the size of the content.
if you started with an cocoa application project, use "awakeFromNib“
to get informed after the nib was loaded, if you started from a
document-based project use "windowControllerDidLoadNib".
I figured out that I can resize the window with [aWindow frame],
thats wrong. this method is a getter. use "setFrame:display:" or
"setFrame:display:animate:" to set a new size and origin.
but I'm not sure how to properly calculate the window size, so that
the view fits my content.
NSMakeRect(...)
i.e. Let's say I get the window, open my data file and I see I need
a view area of 120x120. The custom view needs to be 120x120. How
do you figure out the appropriate window size?
Question 2:
- When I'm resizing the window, how do you figure out the desktop
size, so that you don't make a window that is too big and goes
offscreen.
every NSWindow object has a "screen“ getter, that returns the NSScreen
object representing the screen it is drawn on.
Thanks for your time,
i suggest: read the documentation.
