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。
答案 0 :(得分:1)
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:
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()。
