QT實現不規則窗體
加入技術交流群
看到網上有很多不規則窗體的實現,效果很酷.于是使用QT也實現了一個,QT的不規則窗體實現非常簡單,只需要設置一個mask(遮掩)圖片,這個圖片的格式可以使用png或bmp格式,我使用了png格式,默認窗體是矩形的,使用png圖像,將需要隔離在窗體之外的區域的像素設置為白色或透明色,其他顏色的區域對應顯示出來的窗體.關鍵代碼就幾行.

QPixmap mask(:/IrregularForm/Resources/mask.png);//加載掩碼圖像
setMask(QBitmap(mask.mask())); //設置窗體的掩碼圖像,摳除圖像的白色區域實現不規則窗體
QPalette p;//設置調色板
p.setBrush(QPalette::Window, QBrush(mask));//將調色板的畫刷設置為掩碼位圖,在不規則窗體上顯示出掩碼位圖
setPalette(p);
mouseMovePos = QPoint(0, 0);
}
IrregularForm::~IrregularForm()
{
}
void IrregularForm::mouseMoveEvent(QMouseEvent *event)//鼠標按下并移動則移動不規則窗體
{
if(mouseMovePos != QPoint(0, 0))
{
move(geometry().x() + event->globalPos().x() - mouseMovePos.x(), geometry().y() + event->globalPos().y() - mouseMovePos.y());
mouseMovePos = event->globalPos();
}
