\class QxtWindowSystem
\inmodule QxtWidgets
\brief The QxtWindowSystem class provides means for accessing native windows.
\bold {Note:} The underlying window system might or might not allow one to alter
states of windows belonging to other processes.
\warning QxtWindowSystem is portable in principle, but be careful while
using it since you are probably about to do something non-portable.
\section1 Advanced example usage:
\code
class NativeWindow : public QWidget {
public:
NativeWindow(WId wid) {
QWidget::create(wid, false, false); // window, initializeWindow, destroyOldWindow
}
~NativeWindow() {
QWidget::destroy(false, false); // destroyWindow, destroySubWindows
}
};
\endcode
\code
WindowList windows = QxtWindowSystem::windows();
QStringList titles = QxtWindowSystem::windowTitles();
bool ok = false;
QString title = QInputDialog::getItem(0, "Choose Window", "Choose a window to be hid:", titles, 0, false, &ok);
if (ok)
{
int index = titles.indexOf(title);
if (index != -1)
{
NativeWindow window(windows.at(index));
window.hide();
}
}
\endcode
\bold {Note:} Currently supported platforms are \bold X11 and \bold Windows.
