我正在尝试使用本教程中的代码,但结果是一个灰色的单元格,并且单元格中没有图像(参见屏幕截图)。自从我开始寻找将图像添加到网格单元格的解决方案已经有好几天了,我发现这个解决方案是迄今为止最简单的解决方案,但它对我不起作用。拜托,有人可以帮我解决这个问题,以便我可以继续我的项目吗?这将不胜感激。谢谢你。
这是代码:
import wx
import wx.grid
class MyApp(wx.App):
def OnInit(self):
frame = wx.Frame(None, -1, title = "wx.Grid - Bitmap example")
grid = wx.grid.Grid(frame)
grid.CreateGrid(1,1)
img = wx.Bitmap(r"E:\Dropbox2\Dropbox\Ubot\Ubot\Python\Magnify\Tkinter Magnify\Tests\python-logo.png", wx.BITMAP_TYPE_PNG)
imageRenderer = MyImageRenderer(img)
grid.SetCellRenderer(0,0,imageRenderer)
grid.SetColSize(0,img.GetWidth()+2)
grid.SetRowSize(0,img.GetHeight()+2)
frame.Show(True)
return True
class MyImageRenderer(wx.grid.PyGridCellRenderer):
def __init__(self, img):
wx.grid.PyGridCellRenderer.__init__(self)
self.img = img
def Draw(self, grid, attr, dc, rect, row, col, isSelected):
image = wx.MemoryDC()
image.SelectObject(self.img)
dc.SetBackgroundMode(wx.SOLID)
if isSelected:
dc.SetBrush(wx.Brush(wx.BLUE, wx.SOLID))
dc.SetPen(wx.Pen(wx.BLUE, 1, wx.SOLID))
else:
dc.SetBrush(wx.Brush(wx.WHITE, wx.SOLID))
dc.SetPen(wx.Pen(wx.WHITE, 1, wx.SOLID))
dc.DrawRectangleRect(rect)
width, height = self.img.GetWidth(), self.img.GetHeight()
if width > rect.width-2:
width = rect.width-2
if height > rect.height-2:
height = rect.height-2
dc.Blit(rect.x+1, rect.y+1, width, height, image, 0, 0, wx.COPY, True)
app = MyApp(0)
app.MainLoop()
我得到的结果是:
