Question

我用wcc和wxSmith构建的wxWidgets程序有几个带有文本和按钮的sizer，一个wxMathPlot窗口和一个wxGrid。当我在选择中选择某些内容时，网格会填充不同数量的信息，并在必要时增加更多行或删除不必要的行。当我从1行开始时，当做出选择时，仍然会显示一行，但是当我触摸窗口的边框以调整其大小时，所有内容都会调整大小。网格增长使得每行显示时没有滚动条，并且绘图窗口会根据网格离开的空间而增大或缩小。是否有可能对此行为进行编码，因此每次网格获得新输入时都会调用它？我试过

UserGrid->Fit();
SendSizeEvent();

在网格方法的最后，但这不起作用。我有一个OnResize()方法如下：

void Lizenz_Logfile_ReaderFrame::OnResize(wxSizeEvent& event)
{
    DoGetBestSize();
    UserGrid->Fit();
    //UserGrid->Refresh();
    Layout();

}

这是我的布局（如果我尝试过的某些设置会创建想要的行为）

有没有办法让窗口调整大小以便网格完全显示？

编辑：正如我在调试时发现的那样，OnResize()在实际调整窗口大小时永远不会被调用。它必须是在后台完成的事情，因为我对窗口大小没有做任何其他事情。

编辑2：在尝试了很多之后，似乎在使用UserGrid->AppendRow()后，网格不能很好地重绘。在该行之后，预先可见的滚动条消失，并且仅在用户调整窗口大小时才重新出现。我已经尝试了UserGrid->AdjustScrollbars()，然后UserGrid->ForceRefresh()没有效果。

来自http://docs.wxwidgets.org/trunk/overview_windowsizing.html， wxWidgets提供了两种主要的调整大小的方法：

wxWindow :: Fit（）设置适合其子项的窗口大小。添加每个子项的大小，然后此父窗口更改它尺寸适合所有人。
wxWindow :: Layout（）相反。孩子们会改变他们的体型，根据sizer规则，它们可以适应可用的空间他们的父母。 [...]是容器窗口的默认EVT_SIZE处理程序调用的内容

因为网格可以有数千行/列，所以它的大小可能很大。不要试图告诉父母要适应它。您最好为网格（或其大小）设置最大和最小大小，然后在每次更改行数/列数或大小时使用Fit（）或Layout（）。

自动调整wxGrid的大小
