标题基本上说这一切。我想创建一个可以在窗口内拖动的图像。我的代码到目前为止都是这样做的,但由于某种原因,即使我使用scaled()函数来调整它的大小,图像显得非常小。另外,如果我更改scaled()函数内的值,则图像消失。PySide Qt:拖放图像
from PySide.QtGui import *
from PySide.QtCore import *
import sys
class Label(QLabel):
def __init__(self, title, parent):
super(Label, self).__init__(title, parent)
self.setup()
def setup(self):
folder_pic = QPixmap("path")
folder_size = folder_pic.scaled(64, 64)
self.label = QLabel(self)
self.label.setPixmap(folder_size)
def mouseMoveEvent(self, e):
if e.buttons() != Qt.LeftButton:
return
mimeData = QMimeData(self)
drag = QDrag(self)
drag.setMimeData(mimeData)
drag.setHotSpot(e.pos() - self.rect().topLeft())
dropAction = drag.start(Qt.MoveAction)
class Example(QWidget):
def __init__(self):
super(Example, self).__init__()
self.initUI()
def initUI(self):
self.setAcceptDrops(True)
self.button = Label("", self)
self.button.move(100, 65)
self.setWindowTitle('Click or Move')
self.setGeometry(300, 300, 280, 150)
def dragEnterEvent(self, e):
e.accept()
def dropEvent(self, e):
position = e.pos()
self.button.move(position)
e.setDropAction(Qt.MoveAction)
e.accept()
if __name__ == "__main__":
app = QApplication(sys.argv)
mywin = Example()
mywin.show()
sys.exit(app.exec_())
