### Ignore areas and etc
```cpp
const QWindow *win = widget.windowHandle();
WinNativeEventFilter::WINDOWDATA data = {};
QWindow *win = widget.windowHandle();
// All the following values should not be DPI-aware, just use the
// original numbers, assuming the scale factor is 1.0, don't scale
// them yourself, this code will do the scaling according to DPI
// internally and automatically.
// Maximum window size
data.maximumSize = {1280, 720};
win->setMaximumSize(1280, 720);
// Minimum window size
data.minimumSize = {800, 540};
// How to set ignore areas:
// The geometry of something you already know, in window coordinates
data.ignoreAreas.append({100, 0, 30, 30});
// The geometry of a widget, in window coordinates.
// It won't update automatically when the geometry of that widget has
// changed, so if you want to add a widget, which is in a layout and
// it's geometry will possibly change, to the ignore list, try the
// next method (ignoreObjects) instead.
data.ignoreAreas.append(pushButton_close.geometry());
win->setMinimumSize(800, 540);
// The **POINTER** of a QWidget or QQuickItem
data.ignoreObjects.append(ui->pushButton_minimize);
// Pass data as the second parameter
WinNativeEventFilter::addFramelessWindow(win, &data);
// Or
WinNativeEventFilter::setWindowData(win, &data);
// Or modify the window data of a specific window directly:
const auto data = WinNativeEventFilter::getWindowData(win);
if (data) {
data->borderWidth = 5;
data->borderHeight = 5;
data->titleBarHeight = 30;
}
WinNativeEventFilter::setIgnoredObjects(win, {ui->minimizeBtn, ui->closeBtn});
// The frameless window is resizable by default.
WinNativeEventFilter::setWindowResizable(win, false);
win->setFlag(Qt::MSWindowsFixedSizeDialogHint);
