DupeNewWindow()

USAGE

NewWindow = (struct NewWindow *) DupeNewWindow(NewWindow)

FUNCTION

This makes a copy of the supplied NewWindow structure and its Gadget list. Gadget structures are allocated and copied into. Where appropriate, StringInfo and PropInfo structures are allocated. For StringInfo structures, a string buffer is also allocated and the original string copied into it.

Images, Borders, and IntuiText structures are not copied, rather they are pointed to. This is because they are used only for rendering, so there is no danger in having seversl different windows use these same structures, since they are intend to be read only. If for some reasons, you wish to use others, you may put them in after thelist ist duplicated.

The purpose of this routine is to provide a method for generating multiple copies of the same window, so they can run concurrently.

To do this, create your static NewWindow structure und Gadget list (you could use POWERWindows). Dupe it. You might then create a task opens that window. Dupe the NewWindow again and create another task that opens another window. Althought identical copies of the same window will exist on the screen, mucking with one can not effect the other. When each task is done, it closes its window, then returns the NewWindow and Gadget list with a call to DeleteNewWidow.

Note that now you are generating Gadgets dynamically, you will need to use GetGadget if you wish to access a particular gadget, since the gadget address can't be hard coded (nor should it be).

INPUTS

NewWindow = Pointer to the NewWindow structure to copy

RESULT

NewWindow = Pointer to the copied NewWindow, or NULL if it ran out of memory.
