我有一个面板来控制wxPython框架中matplotlib图形的编辑。 wxPython安装最近从2.6.4.0更新到2.8.12.1并且它破坏了一些东西，即滚动面板不再填充块而是保持最小尺寸。我刚刚从一年前开始接受这个，所以我有点生疏了。任何帮助将不胜感激！
下面是代码的精简版本，可以单独运行并显示问题。 ScrolledWindow应该扩展到400px。当我运行它时self.scroll.GetSize()会返回(292, 257)但显然没有显示那个大小。

self.label = "line #%s"%i

wx.Frame.__init__(self, parent, -1, "Edit Plot")
self.parent = parent

# Set size
self.scroll.SetSizer(lineSizer)

if height > 400:

self.scroll.SetScrollbars(0, 1, 1,1)
print "set scrollbars at %s x %s"%(width, height)

parent = wx.Frame(None, wx.ID_ANY, 'test', size=(300,300))
plot = FakePlot()
panel = PlotEditFrame(parent, plot)
panel.Show()
app.MainLoop()
我无法弄清楚哪些面板需要调整大小。我试过的一些事情无济于事：
# These have no visible effect
boxSizer.SetMinSize((width, height))
self.scroll.SetVirtualSize((width, height))
lineBoxSizer.Fit(self.scroll)
lineBoxSizer.SetVirtualSizeHints(self.scroll)
# This makes the window the right size, but not the scroll panel
lineBoxSizer.SetMinSize((width, height))
答案 0 :(得分：1)
我编辑了一些代码以使其正常工作：
import wx
# spoof the necessary matplotlib objects
class FakePlot:
def __init__(self):
self.figure = FakeFigure()
def get_figure(self):
return self.figure
class FakeFigure:
def __init__(self):
self.axes = [FakeAxis() for i in range(0,2)]
class FakeAxis:
def __init__(self):
self.lines = [FakeLine(i) for i in range(0, 4)]
class FakeLine:
def __init__(self,i):
self.label = "line #%s"%i
def get_label(self):
return self.label
class PlotEditFrame(wx.Frame):
"""
This class holds the frame for plot editing tools
"""
def __init__(self, parent, plot, size):
"""Constructor for PlotEditFrame"""
wx.Frame.__init__(self, parent, -1, "Edit Plot", size=size)
self.parent = parent
self.plot = plot
self.figure = plot.get_figure()
self.advanced_options = None
self.scroll = wx.ScrolledWindow(self, -1)
self.InitControls()
def InitControls(self):
"""Create labels and controls based on the figure's attributes"""
# Get current axes labels
self.lineCtrls = [( wx.StaticText(self.scroll, -1, "Column:"),
wx.StaticText(self.scroll, -1, "Color:"),
wx.StaticText(self.scroll, -1, ""))]
for axis in self.figure.axes:
for line in axis.lines:
color = wx.Colour(255,0,0,0)
lineTxt = wx.TextCtrl(self.scroll, -1, line.get_label(), size=(175,-1))
lineColor = wx.TextCtrl(self.scroll, -1, "#%02x%02x%02x"%color.Get())
lineBtn = wx.Button(self.scroll, -1, size=(25,25))
lineBtn.SetBackgroundColour(color)
self.lineCtrls.append((lineTxt, lineColor, lineBtn))
# Place controls
boxSizer = wx.BoxSizer(wx.VERTICAL)
lineBox = wx.StaticBox(self, -1, "Lines")
lineBoxSizer = wx.StaticBoxSizer(lineBox, wx.VERTICAL)
lineSizer = wx.FlexGridSizer(rows=len(self.lineCtrls)+1, cols=4, vgap=3, hgap=3)
for ctrls in self.lineCtrls:
lineSizer.AddMany([(ctrls[0], 0, wx.ALIGN_LEFT | wx.EXPAND),
(ctrls[1], 0, wx.ALIGN_LEFT),
(ctrls[2], 0, wx.ALIGN_CENTER| wx.FIXED_MINSIZE),
((3,3), 0, wx.ALIGN_CENTER)])
lineSizer.AddGrowableCol(0)
# Set size
self.scroll.SetSizer(lineSizer)
width = self.scroll.GetBestSize().width
height = self.scroll.GetBestSize().height
if height > 400:
height = 400
width = width + 25 # button size
self.scroll.SetSize((width, height))
self.scroll.SetScrollbars(0, 1, 1,1)
print "set scrollbars at %s x %s"%(width, height)
lineBoxSizer.Add(self.scroll, 1, wx.EXPAND)
boxSizer.Add(lineBoxSizer, 1, wx.EXPAND)
self.SetSizer(boxSizer)
self.SetAutoLayout(1)
#self.Fit()
height = self.GetSize().GetHeight()
self.SetSizeHints(minH=height, maxH=height,
minW=width, maxW=width*5)
if __name__ == '__main__':
app = wx.App(False)
plot = FakePlot()
frame = PlotEditFrame(None, plot, size=(300,300))
frame.Show()
app.MainLoop()
主要是在以下两行中将比例设置为“1”：
lineBoxSizer.Add(self.scroll, 1, wx.EXPAND)
boxSizer.Add(lineBoxSizer, 1, wx.EXPAND)
我改变了启动程序的方式，因为在这种情况下将框架放在另一个框架内是有点傻。 PySimpleApp也被弃用了，所以我也改变了。我几乎从未找到过“Fit（）”方法的好用，所以我把它拿出来，因为它压缩了初始的GUI太多了。
希望有所帮助！
