wxpython:用另一个wx.panel覆盖wx.panel，但是新面板的大小无法正确调整 [英] wxpython: overlay wx.panel with another wx.panel but new panel doesn't resize right

问题描述

我有一个带有带2个面板的分离器的框架.这些面板中的一个(右一个= choicePanel)具有一个按钮，该按钮应在choicepanel的同一位置打开一个新面板(infopanel).我使用了这种技术( wxPython :将wx.Panel覆盖在现有wx.Panel上的好方法).

I've a frame with a splitter with 2 panels. one of these panels (right one = choosePanel) has a button which should open a new panel (infopanel) on the same place of the the choosepanel. I used this technique (wxPython: Good way to overlay a wx.Panel on an existing wx.Panel).

这部分有效.但是信息面板的大小无法正确调整.当我在选择面板的位置添加此面板硬编码后，它就可以工作了. 但是当我使用叠加技术时，会发生一些事情.

This part works. But the infopanel doesn't resize right. When I add this panelhardcoded in the place of choosepanel, then it works. But when I use the overlay technique something happens.

代码:

class Main(wx.Frame):

def __init__(self, parent=None, id=-1, notify_channel="browser_view",**kwargs):
    wx.Frame.__init__(self, parent, id, config.programname)
    self.parent = parent
    self.notify_channel = notify_channel
    pub.subscribe(self.on_message, notify_channel)

    self.backgroundpanel = wx.Panel(self, wx.ID_ANY)
    self.splitter = wx.SplitterWindow(self.backgroundpanel, wx.ID_ANY, style=wx.SP_LIVE_UPDATE | wx.SP_BORDER)# style=wwx.SP_LIVE_UPDATE : Don't draw XOR line but resize the child windows immediately.
    self.filter = filter_view.Main(self.splitter, wx.ID_ANY, notify_channel=self.notify_channel)
    self.menubar = menubar_view.Main(self, wx.ID_ANY, notify_channel=self.notify_channel)
    self.statusbar = self.CreateStatusBar()
    self.ChoosePanel = choosePanel_view.Main(self.splitter, wx.ID_ANY)
    # self.ChoosePanel = cellinfo_view.Main(self.splitter, wx.ID_ANY, notify_channel="cellinfo_view")

    self._do_layout()
    self._do_bindings()

    self.Maximize()
    self.Show()

def _do_layout(self):
    self.backgroundsizer = wx.BoxSizer()
    self.sizer = wx.BoxSizer(wx.HORIZONTAL)
    self.backgroundsizer.Add(self.backgroundpanel, 1, wx.EXPAND)
    self.SetMenuBar(self.menubar)
    self.sizer.Add(self.splitter, 1, wx.EXPAND)
    self.backgroundpanel.SetSizer(self.sizer)
    self.sizer.Fit(self.backgroundpanel)
    self.SetSizer(self.backgroundsizer)
    self.backgroundsizer.Fit(self)
    self.splitter.SplitVertically(self.filter, self.ChoosePanel, 500)
    self.splitter.SetMinimumPaneSize(50)

当我单击选择面板中的按钮时，有一个发布消息返回到此文件:

When I click on the button in the choosepanel, there is a pubsub message back to this to this file:

def on_cellinfo_panel(self,message):
    # print self.ChoosePanel.GetPosition()
    self.ChoosePanel.Hide()
    self.cellinfo = cellinfo_view.Main(self.splitter, wx.ID_ANY, notify_channel="cellinfo_view", style=wx.EXPAND)
    self.cellinfo.SetPosition((504, 0))
    self.cellinfo.Layout()

切换这些2:

    self.ChoosePanel = choosePanel_view.Main(self.splitter, wx.ID_ANY)
    # self.ChoosePanel = cellinfo_view.Main(self.splitter, wx.ID_ANY, notify_channel="cellinfo_view")

推荐答案

我已经用另一种方法解决了这个问题.我仍然有self.ChoosePanel在拆分器中.但是，我没有打开新面板，而是在self.choosepanel中也添加了第二个面板(self.cellinfo)，但已隐藏.

I've solved this problem with another approach. I still have the self.ChoosePanel in the splitter. But instead of opening a new panel, I just added the second panel (self.cellinfo) also in the self.choosepanel, but hidden.

因此，在调用self.choosepanel时，将显示choisepanel并隐藏self.cellinfo面板，单击按钮时，将隐藏选择面板并显示self.cellinfo面板.

So when calling self.choosepanel, the choisepanel is showed and the self.cellinfo panel is hidden, and when clicking the button the choice panel is hidden and the self.cellinfo panel is showed.
