晚上好/早上好，
我一直在研究一个程序，并意识到在较低的分辨率下，大部分程序都会被切断。为了解决这个问题，我决定在 GUI 中添加一个滚动窗口。环顾四周，我发现了这个例子：
import wx as wx
class MainFrame(wx.Frame):
def __init__(self, *args, **kwargs):
wx.Frame.__init__(self, *args, **kwargs)
#Panel that holds all the other panels
self.mainPanel = wx.ScrolledWindow(self, -1)
self.mainPanel.SetScrollbars(1, 1, 1, 1)
self.mainPanel.SetBackgroundColour("LIGHT GREY")
#Panels in mainPanel
self.lefttopPanel = wx.Panel(self.mainPanel, -1)
self.lefttopPanel.SetBackgroundColour("WHITE")
self.sizewidgets(self.panelwidgets(
text='Left Top Panel',
num=12,
parent=self.lefttopPanel),
parent=self.lefttopPanel)
self.leftmiddlePanel = wx.Panel(self.mainPanel, -1)
self.leftmiddlePanel.SetBackgroundColour("WHITE")
self.sizewidgets(self.panelwidgets(
text='Left Middle Panel',
num=6,
parent=self.leftmiddlePanel),
parent=self.leftmiddlePanel)
self.leftbottomPanel = wx.Panel(self.mainPanel, -1)
self.leftbottomPanel.SetBackgroundColour("WHITE")
self.sizewidgets(self.panelwidgets(
text='Left Bottom Panel',
num=8,
parent=self.leftbottomPanel),
parent=self.leftbottomPanel)
self.righttopPanel = wx.Panel(self.mainPanel, -1)
self.righttopPanel.SetBackgroundColour("WHITE")
self.sizewidgets(self.panelwidgets(
text='Right Top Panel',
num=8,
parent=self.righttopPanel),
parent=self.righttopPanel)
self.rightbottomPanel = wx.Panel(self.mainPanel, -1)
self.rightbottomPanel.SetBackgroundColour("WHITE")
self.sizewidgets(self.panelwidgets(
text='Right Bottom Panel',
num=8,
parent=self.rightbottomPanel),
parent=self.rightbottomPanel)
mpsizer = wx.GridBagSizer(vgap=4, hgap=4)
mpsizer.Add(self.lefttopPanel, pos=(0,0), span=(1,1), flag=wx.EXPAND)
mpsizer.Add(self.leftmiddlePanel, pos=(1,0), span=(1,1), flag=wx.EXPAND)
mpsizer.Add(self.leftbottomPanel, pos=(2,0), span=(1,2), flag=wx.EXPAND)
mpsizer.Add(self.righttopPanel, pos=(0,1), span=(2,2), flag=wx.EXPAND)
mpsizer.Add(self.rightbottomPanel, pos=(2,2), span=(1,1), flag=wx.EXPAND)
mpsizer.AddGrowableCol(1)
mpsizer.AddGrowableRow(1)
self.mainPanel.SetSizer(mpsizer)
#Adding a refresh to resize event
self.Bind(wx.EVT_SIZE, self.OnResize)
self.Show()
def OnResize(self, event):
self.Refresh()
event.Skip()
def sizewidgets(self, widgetlist , parent):
psizer = wx.GridSizer(cols=2, vgap=5,hgap=5)
for widget in widgetlist:
psizer.Add(widget)
parent.SetSizer(psizer)
def panelwidgets(self, text, num, parent):
widgets = []
for i in range(num):
widgets += [wx.StaticText(parent, label=text)]
return widgets
if __name__ == "__main__":
app = wx.App()
MainFrame(None, size=(800, 800), title="GridBagSizer Problem")
app.MainLoop()
这个例子效果很好，所以我决定尝试修改它以与我的程序一起使用，因为我没有运气在我的整个程序中添加一个滚动窗口，所以我做了这些改变：
import wx as wx
class MainFrame(wx.Frame):
def __init__(self, *args, **kwargs):
wx.Frame.__init__(self, *args, **kwargs)
#Panel that holds all the other panels
self.mainPanel = wx.ScrolledWindow(self, -1)
self.mainPanel.SetScrollbars(1, 1, 1, 1)
self.mainPanel.SetBackgroundColour("LIGHT GREY")
# Handles the c reation of all of the static text labels
def make_label(text, starty, startx, height, width):
self.label = wx.StaticText(self, -1, text, wx.DefaultPosition, wx.DefaultSize)
sizer.Add(self.label, (starty, startx), (height, width), wx.EXPAND)
return self.label
sizer = wx.GridBagSizer()
for i in range(0, 4):
# all the labels
make_label('Voltage', 7, i*5, 1, 1)
make_label('Current', 8, i*5, 1, 1)
make_label('Power', 9, i*5, 1, 1)
make_label('Rail 1', 6, (i*5)+1, 1, 1)
make_label('Rail 2', 6, (i*5)+2, 1, 1)
make_label('Rail 3', 6, (i*5)+3, 1, 1)
make_label('Total Power', 6, (i*5)+4, 1, 1)
make_label('Status:', 14, (i*5), 1, 1)
sizer.AddGrowableRow(1)
sizer.AddGrowableCol(1)
self.mainPanel.SetSizer(sizer)
#Adding a refresh to resize event
self.Bind(wx.EVT_SIZE, self.OnResize)
self.Show()
def OnResize(self, event):
self.Refresh()
event.Skip()
def sizewidgets(self, widgetlist , parent):
psizer = wx.GridSizer(cols=2, vgap=5,hgap=5)
for widget in widgetlist:
psizer.Add(widget)
parent.SetSizer(psizer)
def panelwidgets(self, text, num, parent):
widgets = []
for i in range(num):
widgets += [wx.StaticText(parent, label=text)]
return widgets
if __name__ == "__main__":
app = wx.App()
MainFrame(None, size=(800, 800), title="GridBagSizer Problem")
app.MainLoop()
出于某种原因，随着我所做的更改，滚动条只是位于左上角并且不起作用。当我尝试将它添加到更大的程序中时，也会发生同样的事情。任何人都可以帮我解决为什么会这样吗？
