Windows vs OSX Screen Size Function

[lugesm]

This question is so basic that I am embarrassed to even ask; but here goes anyway . . . .

With Windows I could click on the equivalent of the green+ icon in the upper left corner of the screen and cause that window to enlarge to completely fill the screen.

With OSX, this green+ icon in the upper left corner does not seem to perform any useful function. It does toggle between a larger and smaller window, but there does not seem to be a way to do the Windows equivalent with this function so that one click fills the screen.

Am I missing something?

Sorry this is so lame, but I have been using a Mac for a year, and I just don't use the green button.

the Zoom (green) button toggles between the user set window size and a window size big enough to display the content of the window.

but if this hasnt been set by the developer for the app it simply fills the entire screen like a Windows app. this is the case with some of Apple's apps like iPhoto, Mail, iCal and most of the Utilities.

if you want an app to be full screen just enlarge it by clicking and dragging the handle on the bottom right of the window. but youll probably get used to the Mac way soon and understand that not all apps need to be enlarged to fullscreen and workflow will increase especially with the use of Exposé and Spaces.
