wxPython:一个可折叠的面板小部件

标签: python user-interface wxpython widget

我有我的主程序窗口,我想制作一个可折叠的面板。我的意思是,一个面板与窗户的一侧对齐,带有折叠/展开按钮。重要的是,当面板折叠/展开时,其他小部件会相应地改变它们的大小以利用它们所具有的空间。

我该怎么做?

这是使用wx.SplitterWindow

的一种方法
import wx, wx.calendar


class FoldableWindowContainer(wx.Panel):
    def __init__(self, parent, left, right):
        wx.Panel.__init__(self, parent)

        sizer = wx.BoxSizer(wx.HORIZONTAL)
        self.SetSizer(sizer)
        self.splitter = wx.SplitterWindow(self, style=wx.SP_LIVE_UPDATE)
        left.Reparent(self.splitter)
        right.Reparent(self.splitter)
        self.left = left
        self.right = right
        self.splitter.SplitVertically(self.left, self.right)
        self.splitter.SetMinimumPaneSize(50)
        self.sash_pos = self.splitter.SashPosition
        sizer.Add(self.splitter, 1, wx.EXPAND)

        fold_button = wx.Button(self, size=(10, -1))
        fold_button.Bind(wx.EVT_BUTTON, self.On_FoldToggle)
        sizer.Add(fold_button, 0, wx.EXPAND)

    def On_FoldToggle(self, event):
        if self.splitter.IsSplit():
            self.sash_pos = self.splitter.SashPosition
            self.splitter.Unsplit()
        else:
            self.splitter.SplitVertically(self.left, self.right, self.sash_pos)


class FoldTest(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None)

        left = wx.Panel(self, style=wx.BORDER_SUNKEN)
        right = wx.Panel(self, style=wx.BORDER_SUNKEN)

        left_sizer = wx.BoxSizer(wx.VERTICAL)
        left.SetSizer(left_sizer)
        left_sizer.Add(wx.calendar.CalendarCtrl(left), 1, wx.EXPAND | wx.ALL, 5)
        left_sizer.Add(wx.Button(left, label="Act"), 0, wx.EXPAND | wx.ALL, 5)

        right_sizer = wx.BoxSizer(wx.VERTICAL)
        right.SetSizer(right_sizer)
        right_sizer.Add(
            wx.StaticText(right, label="Fold panel", style=wx.BORDER_RAISED),
            1, wx.EXPAND | wx.ALL, 5
        )

        FoldableWindowContainer(self, left, right)


app = wx.PySimpleApp()
app.TopWindow = FoldTest()
app.TopWindow.Show()
app.MainLoop()

另外,请查看wxPython演示中的wx.CollapsiblePane。

如果正确创建层次结构,wxPython(和Swing等)的布局管理器应该能够为您执行此操作。让我们假设它绑定在右侧,因此:

+-----------------------------+
|+----------------+ +--------+|
||                | | This is||
||                | | your   ||
||   Other stuff  | | panel  ||
||                | +--------+|
||                | +--------+|
||                | | Another||
||                | | panel  ||
|+----------------+ +--------+|
+-----------------------------+

如果您的布局正确完成,您将拥有一个包含两列的顶级布局,一列用于其他内容,另一列用于右侧容器。

那个容器将拥有它自己的布局管理器,有两行,一行用于顶部面板,一行用于底部。

这样,当您将顶部面板(可折叠的面板)调整为更短(折叠)或更高(展开)时,布局管理器应扩展或缩小底部面板以适应。

显然你可以使用更复杂的布局管理器,我选择了最简单的布局管理器来说明如何在不使用列/行跨度和锚点等讨论混乱的情况下进行操作。您还可以通过反转窗口管理器来更改折叠方向(水平< - >垂直)。

ToniRuža的原始示例,略微修改4.0 / Phoenix下的工作。非常好的工作实例,谢谢Toni!
