使滚动面板的水平滚动条在 wxPython 中永久可见 [英] Making the horizontal scrollbar of a scrolled panel to be permanently visible in wxPython

问题描述

我正在 Windows 8 操作系统上使用 wxPython v3.0 开发 GUI.我对特定滚动面板上的水平滚动条有疑问.在我的 GUI 中，有 2 个名为 panel1 和 panel2 的滚动面板添加到一个名为 mainPanel 的主滚动面板，并且该面板具有垂直滚动酒吧.当 mainPanel 的垂直滚动条移动时，所有面板(panel1 和 panel2)同时移动，这正是我想要的.同样在 panel1 中只有一个水平滚动条(使用 SetupScrolling(scroll_y=False) 在 panel1 上禁用垂直滚动条).我在 panel1 上需要水平滚动条的原因是，如果里面的文本增加，面板也会展开，所以我给了它一个滚动条.

I am developing a GUI with wxPython v3.0 on windows 8 OS. I have a problem regarding the horizontal scroll bar on a particular scrolled panel. In my GUI there are 2 scrolled panels named as panel1 and panel2 added to one main scrolled panel named as mainPanel and this panel has a vertical scroll bar. When ever the vertical scroll bar of the mainPanel is moved all the panels (panel1 & panel2) move simultaneously, this is exactly what I desired. Also in panel1 there is a horizontal scroll bar only (The vertical scroll bar is disabled on panel1 using SetupScrolling(scroll_y=False)). The reason why I need a horizontal scroll bar on panel1 is because if the text inside increases the panel expands too so I gave it a scroll bar.

问题:

panel1 上的这个水平条只有在我滚动 mainPanel 的垂直滚动条(如图所示的最右侧的滚动条)时才可见至底部.

This horizontal bar on panel1 is only visible when I scroll the vertical scroll bar (the scroll bar on extreme right side as shown in the image.) of the mainPanel to the bottom.

如何让 panel1 上的水平滚动条每次都可见?我不想先把mainPanel的垂直滚动条滚动到底部才能访问panel1的水平滚动条?

How can I make the horizontal scroll bar on panel1 to be visible every time? I don't want to first scroll the vertical scroll bar of the mainPanel to the bottom in order to access the horizontal scroll bar of panel1?

感谢您的宝贵时间.

推荐答案

当你不带参数调用方法 SetupScrolling 时，两个滚动条都将处于活动状态，如果你不希望 y 轴滚动条显示使用 scroll_y = False.

When you call method SetupScrolling with no parameters both scroll bars will be active, if you dont want the y axis scroll bar showing use scroll_y = False.

panel21 = wx.lib.scrolledpanel.ScrolledPanel(mainPanel, -1, style=wx.SIMPLE_BORDER)
panel21.SetupScrolling(scroll_y = False)
