#include <FL/Fl_Double_Window.H>

Description

The Fl_Double_Window class provides a double-buffered window. If possible this will use the X double buffering extension (Xdbe). If not, it will draw the window data into an off-screen pixmap, and then copy it to the on-screen window.

It is highly recommended that you put the following code before the first show() of any window in your program:

Fl::visual(FL_DOUBLE|FL_INDEX)

This makes sure you can use Xdbe on servers where double buffering does not exist for every visual.

Fl_Double_Window::Fl_Double_Window(int w, int h, const char label = 0)
Fl_Double_Window::Fl_Double_Window(int x, int y, int w, int h, const char label = 0)

Creates a new Fl_Double_Window widget using the given position, size, and label (title) string.

virtual Fl_Double_Window::~Fl_Double_Window()

The destructor also deletes all the children. This allows a whole tree to be deleted at once, without having to keep a pointer to all the children in the user code.

The pixmap() method does not seem to be implemented, at least not under WIN32...
