问题描述
编辑:发现了如何在我的形状框架上放置一个透明wxPanel,但现在我尝试在wxGridBagSizer上放置一个wxGridBagSizer strong>wxPanel 有一些小部件,但只会出现第一个小部件......有任何想法吗?
原始问题:
好吧,我正在尝试制作一个 wx.ShapedWindow 与 png 背景 具有透明度,问题是它看起来像他们更改了 wx lib,以便在我们可以使用 wx.RegionFromBitmap() 之前在位图上设置形状,但这不再起作用,我尝试使用 wx.Region 只是,但我不知道如何获得透明度!我有一个灰色区域,我想要透明区域....
如果有人可以帮助我!
这是我现在得到的:
import wx
from os import getcwd
class ShapedFrame(wx.Frame):
def __init__(self,parent,id,title):
wx.Frame.__init__(self,None,-1,"Shaped Window",style = wx.FRAME_SHAPED | wx.SIMPLE_BORDER )
self.hasShape = False
self.delta = wx.Point(0,0)
ImgDir = (getcwd()+u"\\img\\ex.png")
self.bmp = wx.Image(ImgDir,wx.BITMAP_TYPE_ANY).ConvertToBitmap()
w,h = self.bmp.GetWidth(),self.bmp.GetHeight()
self.SetClientSize(w,h)
#self.panel = wx.Panel(self,size=(100,100))
panel = Panel(self)
panel.Show()
dc = wx.ClientDC(self)
dc.DrawBitmap(self.bmp,True)
self.SetwindowShape()
self.Bind(wx.EVT_LEFT_DCLICK,self.ondoubleclick)
self.Bind(wx.EVT_LEFT_DOWN,self.OnLeftDown)
self.Bind(wx.EVT_LEFT_UP,self.OnLeftUp)
self.Bind(wx.EVT_MOTION,self.OnMouseMove)
self.Bind(wx.EVT_RIGHT_UP,self.OnExit)
self.Bind(wx.EVT_PAINT,self.OnPaint)
self.Bind(wx.EVT_WINDOW_CREATE,self.SetwindowShape)
################# EDIT ONLY BUTTON 0 WILL APPEAR ########################
button0 = wx.Button(panel,"hello 0")
button1 = wx.Button(panel,"hello 1")
button2 = wx.Button(panel,"hello 2")
button3 = wx.Button(panel,"hello 3")
gBox7 = wx.GridBagSizer(0,0)
gBox7.SetEmptyCellSize((10,10))
gBox7.Add(button0,(0,0))
gBox7.Add(button1,1))
gBox7.Add(button2,(1,0))
gBox7.Add(button3,1))
panel.SetSizer(gBox7)

def OnMouseMove(self,evt):
if evt.Dragging() and evt.LeftIsDown():

self.Move(newPos)

self.ReleaseMouse()
class Panel(wx.Panel):
def __init__(self,parent):
wx.Panel.__init__(self,size=(200,200,),style=wx.TRANSPARENT_WINDOW)
self.CenterOnParent()
app = wx.App()
ShapedFrame(None,None).Show()
app.MainLoop()
解决方法
好的,我找到了一个解决方案,在 wx.coulor 中查找,因为 2.9 他们添加了 wxTransparentColour
所以我替换了:
r = wx.Region(self.bmp,"grey",30)
与:
r = wx.Region(self.bmp,wx.TransparentColour)
它工作正常!希望它也能帮助其他人:)
