// This cocoa adapter can be used in two environments:
|
||||
// First: There is no other code which creates the NSApplication object, so
|
||||
// NeL is completely in charge of starting and setting up the application.
|
||||
// In this case, the NSAutoreleasePool needed to handle the cocoa style memory
|
||||
// management is created by this code.
|
||||
// Second: There is already a NSApplication set up. This could be the case if
|
||||
// NeL is used for example in a Qt widget. So Qt already created all the
|
||||
// NSApplication infrastructure, so it is not set up by this code again!
|
||||
//
|
||||
// Thats why, the g_pool variable (containing a pointer to the NSAutoreleasePool
|
||||
// created by this code) can be used to check whether NeL created the
|
||||
// NSApplication infrastructure itself or not.
|
||||
//
|
||||
// WARNING:
|
||||
// Currently the NSApplication infrastructure is automatically created with the
|
||||
// call to createWindow(). So if for example Qt already created NSApplication,
|
||||
// createWindow() must not be called. Instead, setDisplay() can be provided with
|
||||
// a window handle (on Mac OS Cocoa Qt this is a NSView*). In this case, this
|
||||
// cocoa adapter will skip the NSApplication setup and embed itself into the
|
||||
// provided view running in the already set up application.
