和一个文本框,我在其中试图显示我对其完成一些操作后得到的值。值是sums [i],但是现在我想在文本框中显示值,我这样做:
*TextBox4 << "hello" << size_t sums;
frame->Connect(TEXT_BOX4, wxEVT_COMMAND_BUTTON_CLICKED | wxEVT_COMMAND_ENTER, (wxObjectEventFunction) & MyFrame::OnGenerateKey);
TextBox4 = new wxTextCtrl(this, TEXT_BOX4, wxT(""), wxPoint(200, 200), wxSize(200, 20), wxTE_PROCESS_ENTER | wxTE_READONLY | wxTE_LEFT, wxDefaultValidator, wxT("WxTextBox4"));
然而它会产生以下错误
base.cpp:212:22: error: ambiguous overload for 'operator<<' in '*((MyFrame*)this)->MyFrame::TextBox4 << sum'
base.cpp:212:22: note: candidates are:

请帮帮我。

首先,你不能打印这样的静态数组,你需要迭代它。第二 - 你应该只打印没有类型的总和:
* TextBox4&lt;&lt; “你好”&lt;&lt;款项;
这仍然不足以帮助你 - 我需要更多的背景。
