|
||
|
|
\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
|
||
|
|
}
|

|
|
};

bool ok = false;

QString title = QInputDialog::getItem(0, "Choose Window", "Choose a window to be hid:", titles, 0, false, &ok);
