我想用拖放图像编写脚本。我上传了2张图片（.jpg），并尝试在面板上拖动图片。
当我在面板上拖动firstImage时，一切看起来都很好。
但是当我在面板上拖动secondImage时（特别是当secondImage与firstImage接触时）会发生一个错误。 secondImage的内容位于firstImage的内容之下。我该怎么办，当我拖动secondImage时，其内容位于firstImage的内容之上？谢谢。
script.py
import wx
import wx.lib.buttons as buttons
class Main(wx.Frame):
def __init__(self, parent, title):
wx.Frame.__init__(self, parent, id=-1, title=title, size=(300, 300))
self.panel = wx.Panel(self, wx.ID_ANY, wx.DefaultPosition, size=(300, 300))
firstImage = ButtonImage(self, self.panel, r'.\image_wtf\1.jpg', (20,20))
secondImage = ButtonImage(self, self.panel, r'.\image_wtf\2.jpg', (20, 135))
self.Layout()
class ButtonImage():
def __init__(self, parent, panel, nameImage, pos):
self.panel = panel
self.bmp = wx.Bitmap(nameImage, wx.BITMAP_TYPE_ANY)
### search for a piece of the maximum position (limit boundary)
self.maxPiecePositionX = self.panel.GetSize()[0] - self.bmp.GetSize()[0]
self.maxPiecePositionY = self.panel.GetSize()[1] - self.bmp.GetSize()[1]
self.bmapBtn = wx.BitmapButton(self.panel, id=wx.ID_ANY, bitmap=self.bmp, style=wx.NO_BORDER, pos=pos)
#self.bmapBtn.Bind(wx.EVT_ENTER_WINDOW, self.EnterButton, self.bmapBtn)

self.holdPosition = (event.GetX(), event.GetY())
def OnClickUp(self, event):
self.hold = 0
def MoveButton(self, event):
deltaX, deltaY = 0, 0
if self.hold:
deltaX = event.GetPosition()[0] - self.holdPosition[0]
deltaY = event.GetPosition()[1] - self.holdPosition[1]
newPositionX = self.bmapBtn.GetPosition()[0] + deltaX
newPositionY = self.bmapBtn.GetPosition()[1] + deltaY
if (0 < newPositionX < self.maxPiecePositionX) and (0 < newPositionY < self.maxPiecePositionY):
self.bmapBtn.SetPosition((newPositionX, newPositionY))
else:
self.holdPosition = self.holdPosition[0] + deltaX, self.holdPosition[1] + deltaY
self.bmapBtn.Refresh()
app = wx.PySimpleApp()
frame = Main(None, u"Game")
frame.Show()
app.MainLoop()
最佳答案
您可以使用Raise（）将窗口提升到窗口层次结构的顶部。
def MoveButton():
.................
.................
self.bmapBtn.Raise()
self.bmapBtn.Refresh()
