我正在尝试在同一帧中创建两个垂直堆叠的网格。 由于无法禁用滚动条网格,我正在尝试此转向 第一个网格必须占据框架的顶部,而第二个网格必须占据框架的顶部。当框架调整大小时,顶部网格必须始终保持可见而没有滚动条,而下部网格可以显示滚动条。 这是一个示例代码。唯一的问题是我无法使第一个网格仅占据框架中的大小,无论如何都占据了框架的一半。
import wx
import wx.grid as glib
import wx.lib.scrolledpanel as SP
# The main panel:
class grids(wx.Panel):
def __init__(self, parent):
wx.Panel.__init__(self,parent)
# scrolled panels
resizableScrolledPanel = SP.ScrolledPanel(self)
fixedScrolledPanel = SP.ScrolledPanel(self)
# main sizer for everything:
mainSizer = wx.BoxSizer(wx.VERTICAL)
# create grids
fixGrid = glib.Grid(fixedScrolledPanel)
resizableGrid = glib.Grid(resizableScrolledPanel)
# customize grids
fixGrid.CreateGrid(3,10)
resizableGrid.CreateGrid(20,10)
fixGrid.SetDefaultCellBackgroundColour( [176, 196, 222] )#light steel blue
fixGrid.SetGridLineColour([0,0,0])
[fixGrid.SetRowLabelValue(idx, ["row 1","row 2","row 3"][idx]) for idx in range(3)]
resizableGrid.SetColLabelSize(0)
fixGrid.SetRowLabelSize( wx.grid.GRID_AUTOSIZE )
resizableGrid.SetRowLabelSize( fixGrid.GetRowLabelSize() )
# Create the grids sizers
propSizer = wx.BoxSizer(wx.VERTICAL)
dataSizer = wx.BoxSizer(wx.VERTICAL)
propSizer.Add(fixGrid,1,wx.RIGHT|wx.TOP|wx.EXPAND,5)
dataSizer.Add(resizableGrid,1,wx.RIGHT|wx.BOTTOM|wx.EXPAND,5)
fixedScrolledPanel.SetSizer(propSizer)
resizableScrolledPanel.SetSizer(dataSizer)
fixedScrolledPanel.Layout()
resizableScrolledPanel.Layout()
resizableScrolledPanel.SetupScrolling(scroll_x=True, scroll_y=True)
fixedScrolledPanel.SetupScrolling(scroll_x=False, scroll_y=False)
# add to main sizer
mainSizer.Add(fixedScrolledPanel,1,wx.RIGHT|wx.TOP|wx.EXPAND,5)
mainSizer.Add(resizableScrolledPanel,1,wx.RIGHT|wx.BOTTOM|wx.EXPAND,5)
self.SetSizer(mainSizer)
self.Fit()
print fixedScrolledPanel.GetSize() # returns (0,0)
# The main frame:
class MainFrame(wx.Frame):
def __init__(self,parent,title):
wx.Frame.__init__(self,parent,-1,title=title, size=(850,500))
sizer = wx.BoxSizer(wx.HORIZONTAL)
sizer.Add(grids(self),1,wx.EXPAND)
self.SetSizer(sizer)
self.SetAutoLayout(1)
app = wx.App(False)
frame = MainFrame(None, "Scroll Test")
frame.Show(True)
app.MainLoop()
通常我应该将fixedSizer比例设置为0,对于fixedScrolledPanel,就像这样
mainSizer.Add(fixedScrolledPanel,0,wx.RIGHT|wx.TOP|wx.EXPAND,5)
但是由于fixedScrolledPanel是(0,0)第一个网格消失...

缺少的细节是SetSizeHints
电话; sizer需要知道要扩展到什么。您还希望mainSizer
中的面板具有proportion = 0
。

self.SetSizer(sizer)
sizer.Fit(self)
app = wx.App(False)
frame = MainFrame(None, "Scroll Test")
frame.Show(True)
app.MainLoop()
为了便于阅读,我重新格式化了代码。
