wxPython用于图像和按钮(可调整大小) [英] wxPython for image and buttons (resizable)
问题描述
我想把这样的图像放在 wx.Panel
中:
-
动物应该是按钮,这样如果我点击它们,它们的图像会发生变化,如果我重新点击,图像会恢复正常(因此动物可以被认为是简单的
BitmapToggleButtons
,正如另一个问题所建议的那样) -
此面板应调整大小/重新调整(所有子图像/ togglebuttons也是如此) !)保持纵横比,如果父
wx.Panel
被调整为更小的东西,例如(就像标准 Windows Photo Viewer 那样: ,但现在我完全不知道如何继续(检测点击,用直接DC绘画更新按钮?),这就是赏金的原因。解决方案我用以下方法解决了问题: / p>
从floatcanvas导入导入wx
FloatCanvas
类MyPanel(wx.Panel):
def __init __(self,parent):
super(MyPanel,self).__ init __(parent)
self.sizer = wx.BoxSizer(wx.VERTICAL)
self.SetSizer( self.sizer)
#添加画布
self.Canvas = FloatCanvas.FloatCanvas(self,BackgroundColor =LIGHT GRAY)
self.Canvas.Bind(wx.EVT_SIZE,self.OnSize)
self.sizer.Add(self.Canvas,-1,flag = wx.EXPAND)
#添加一个切换按钮
image_dis = wx.Image('file_disabled.png')
image_ena = wx.Image('file_enabled.png')
img_dis = self。 Canvas.AddScaledBitmap(image_dis,(x,-y),Height = image_dis.GetHeight(),Position ='tl')
img_ena = self.Canvas.AddScaledBitmap(image_ena,(x,-y),Height = image_ena.GetHeight(),Position ='tl')
img_dis.other = img_ena
img_ena.other = img_dis
img_ena.Visible = False
#bind切换按钮事件
img_dis.Bind(FloatCanvas.EVT_FC_LEFT_UP,self.OnToggle)
img_ena.Bind(FloatCanvas.EVT_FC_LEFT_UP,self.OnToggle)
def OnToggle(self,button) :
button.other.Visible = True
button.Visible = False
self.Canvas.Draw(True)
def OnSize(self,event):
event.Skip()
wx.CallLater(1,self.Canvas.ZoomToBB)
I want to put such an image in a
wx.Panel
:The animals should be "buttons" so that if I click on them, their image changes, and if I reclick, the image returns to normal (thus the animals can be considered as simple
BitmapToggleButtons
, as suggested by another question here on SO)This panel should be resized/rescaled (all all the children images / togglebuttons too!) keeping the aspect ratio, if the parent
wx.Panel
is resized to something smaller for example (like would do the standard Windows Photo Viewer : http://res1.windows.microsoft.com/resbox/en/windows%207/main/7eaf462a-86dd-42d2-a789-7413f5472dae_63.jpg)
I am still a bit lost on : how to implement such a clickable (with toggle buttons) and rescalable Canvas?
Edit : I started with something fruitful here Rescale image when parent is resized in wxPython, but now I'm totally stuck about how to continue (detect clicks, update buttons with direct DC Painting ?), that's why the bounty.
解决方案I solved the problem with :
import wx from floatcanvas import FloatCanvas class MyPanel(wx.Panel): def __init__(self, parent): super(MyPanel, self).__init__(parent) self.sizer = wx.BoxSizer(wx.VERTICAL) self.SetSizer(self.sizer) # add a canvas self.Canvas = FloatCanvas.FloatCanvas(self, BackgroundColor = "LIGHT GREY") self.Canvas.Bind(wx.EVT_SIZE, self.OnSize) self.sizer.Add(self.Canvas, -1, flag=wx.EXPAND) # add a toggle button image_dis = wx.Image('file_disabled.png') image_ena = wx.Image('file_enabled.png') img_dis = self.Canvas.AddScaledBitmap(image_dis, (x,-y), Height=image_dis.GetHeight(), Position = 'tl') img_ena = self.Canvas.AddScaledBitmap(image_ena, (x,-y), Height=image_ena.GetHeight(), Position = 'tl') img_dis.other = img_ena img_ena.other = img_dis img_ena.Visible = False # bind the toggle button event img_dis.Bind(FloatCanvas.EVT_FC_LEFT_UP, self.OnToggle) img_ena.Bind(FloatCanvas.EVT_FC_LEFT_UP, self.OnToggle) def OnToggle(self, button): button.other.Visible = True button.Visible = False self.Canvas.Draw(True) def OnSize(self, event): event.Skip() wx.CallLater(1, self.Canvas.ZoomToBB)
