问题描述
dc.SetPen(wx.Pen(wx.BLACK, 0))
dc.SetBrush(wx.Brush("C0C0C0"))
dc.DrawRectangle(50,50,50,50)
这是我绘制一个 50x50 的无边框灰色框的最佳尝试.但是,将笔宽设置为 0 似乎没有任何作用,设置画笔只会将填充从纯白色变为纯黑色.
This is my best attempt at drawing a 50x50, gray box with no border. However, setting the pen width to 0 doesn't seem to accomplish anything, and setting the brush only changes the fill from pure white to pure black.
这是在面板的上下文中,以防它是问题的一部分:
Here's it in the context of a panel, in case it's part of the problem:
class DrawRect(wx.Panel):
def __init__(self,parent=None,id=-1,pos=(-1,-1),size=(-1,-1),style=0):
wx.Panel.__init__(self,parent,id,size,pos,style)
self.SetBackgroundColour("#D18B47")
self.Bind(wx.EVT_PAINT,self.onPaint)
def onPaint(self, event):
event.Skip()
dc = wx.PaintDC(event.GetEventObject())
self.drawRect(dc)
def drawRect(self,dc):
dc.SetPen(wx.Pen("FFCE8A", 0))
dc.SetBrush(wx.Brush("C0C0C0"))
dc.DrawRectangle(50,50,50,50)
推荐答案
这会生成一个灰色矩形:
This makes a grey rectangle:
import wx
class MyPanel(wx.Panel):
""" class MyPanel creates a panel to draw on, inherits wx.Panel """
def __init__(self, parent, id):
# create a panel
wx.Panel.__init__(self, parent, id)
self.SetBackgroundColour("white")
self.Bind(wx.EVT_PAINT, self.OnPaint)
def OnPaint(self, evt):
"""set up the device context (DC) for painting"""
self.dc = wx.PaintDC(self)
self.dc.BeginDrawing()
self.dc.SetPen(wx.Pen("grey",style=wx.TRANSPARENT))
self.dc.SetBrush(wx.Brush("grey", wx.SOLID))
# set x, y, w, h for rectangle
self.dc.DrawRectangle(250,250,50, 50)
self.dc.EndDrawing()
del self.dc
app = wx.PySimpleApp()
# create a window/frame, no parent, -1 is default ID
frame = wx.Frame(None, -1, "Drawing A Rectangle...", size = (500, 500))
# call the derived class, -1 is default ID
MyPanel(frame,-1)
# show the frame
frame.Show(True)
# start the event loop
app.MainLoop()
