QPixmap::grabWindow截出来的图片为啥没有鼠标标志呢
将鼠标画上去是一种方法 但总感觉不太好

这个没注意过，好像没有带鼠标的。 windows自带的截图工具也没有鼠标。

实现里面就不抓mouse cursor的 所以还是换别的思路把 QPixmap QPixmap::grabWindow(WId winId, int x, int y, int w, int h ) { RECT r; GetClientRect(winId, &r); if (w < 0) w = r.right - r.left; if (h < 0) h = r.bottom - r.top; #ifdef Q_WS_WINCE_WM if (qt_wince_is_pocket_pc()) { QWidget *widget = QWidget::find(winId); if (qobject_cast<QDesktopWidget *>(widget)) { RECT rect = {0,0,0,0}; AdjustWindowRectEx(&rect, WS_BORDER | WS_CAPTION, FALSE, 0); int magicNumber = qt_wince_is_high_dpi() ? 4 : 2; y += rect.top - magicNumber; } } #endif // Create and setup bitmap HDC display_dc = GetDC(0); HDC bitmap_dc = CreateCompatibleDC(display_dc); HBITMAP bitmap = CreateCompatibleBitmap(display_dc, w, h); HGDIOBJ null_bitmap = SelectObject(bitmap_dc, bitmap); // copy data HDC window_dc = GetDC(winId); BitBlt(bitmap_dc, 0, 0, w, h, window_dc, x, y, SRCCOPY #ifndef Q_WS_WINCE | CAPTUREBLT #endif ); // clean up all but bitmap ReleaseDC(winId, window_dc); SelectObject(bitmap_dc, null_bitmap); DeleteDC(bitmap_dc); QPixmap pixmap = QPixmap::fromWinHBITMAP(bitmap); DeleteObject(bitmap); ReleaseDC(0, display_dc); return pixmap; }
