wxWidgets在wxFrame中像在CMake GUI中一样调整子区域的大小

如何解决wxWidgets在wxFrame中像在CMake GUI中一样调整子区域的大小

我是wxWidgets的新手，所以我正在尝试使窗口类似于CMake GUI中的窗口。如何将区域分为两个可自调整大小的区域：

我正在使用linux进行开发和cmake。 我没有使用任何UI编辑器

PS：很抱歉我的英语，这不是我的母语：o

解决方法

在CMake GUI中创建元素可扩展的框架的方法是将wxSplitterWindow与sizer一起使用，并在sizer标志构造函数中使用比例来指定每个项目应扩展多少。

这是一个简短的例子：

// For compilers that support precompilation,includes "wx/wx.h".
#include "wx/wxprec.h"

#ifdef __BORLANDC__
    #pragma hdrstop
#endif

// for all others,include the necessary headers (this file is usually all you
// need because it includes almost all "standard" wxWidgets headers)
#ifndef WX_PRECOMP
    #include "wx/wx.h"
#endif

#include <wx/splitter.h>

class MyFrame: public wxFrame
{
    public:
        MyFrame();
};

MyFrame::MyFrame()
        :wxFrame(NULL,wxID_ANY,"CMake style frame",wxDefaultPosition,wxSize(600,400))
{
    wxSplitterWindow* splitter = new wxSplitterWindow(this,wxDefaultSize,wxSP_LIVE_UPDATE);

    wxPanel* top = new wxPanel(splitter,wxID_ANY);

    wxStaticText* statText1 = new wxStaticText(top,"Where is the source");
    wxTextCtrl* textCtrl1 = new wxTextCtrl(top,wxEmptyString);
    wxButton* button1 = new wxButton(top,"Browse Source...");
    wxBoxSizer* sizer2 = new wxBoxSizer(wxHORIZONTAL);
    sizer2->Add(statText1,wxSizerFlags(0).Centre());
    sizer2->Add(textCtrl1,wxSizerFlags(1).Border(wxLEFT));
    sizer2->Add(button1,wxSizerFlags(0).Border(wxLEFT));

    wxStaticText* statText2 = new wxStaticText(top,"Where to build the binaries:");
    wxStaticText* statText3 = new wxStaticText(top,"Search:");

    wxTextCtrl* textCtrl2 = new wxTextCtrl(top,wxEmptyString,wxTE_MULTILINE|wxTE_DONTWRAP);
    wxStaticText* statText4 = new wxStaticText(top,"Press Configure:");
    wxButton* button2 = new wxButton(top,"Configure");

    wxBoxSizer* topSizer = new wxBoxSizer(wxVERTICAL);

    // Now Add the items to the backfround panel's sizer:
    topSizer->Add(sizer2,wxSizerFlags(0).Expand().DoubleBorder(wxALL));
    topSizer->Add(statText2,wxSizerFlags(0).DoubleBorder(wxLEFT|wxRIGHT|wxBOTTOM));
    topSizer->Add(statText3,wxSizerFlags(0).DoubleBorder(wxLEFT|wxRIGHT|wxBOTTOM));

    // The next item is added with proportion 1 so that it will expand in size.
    topSizer->Add(textCtrl2,wxSizerFlags(1).Expand().DoubleBorder(wxLEFT|wxRIGHT|wxBOTTOM));
    topSizer->Add(statText4,wxSizerFlags(0).Center().DoubleBorder(wxLEFT|wxRIGHT|wxBOTTOM));
    topSizer->Add(button2,wxSizerFlags(0).DoubleBorder(wxLEFT|wxRIGHT));

    top->SetSizer(topSizer);


    wxPanel* botton = new wxPanel(splitter,wxID_ANY);
    wxTextCtrl* textCtrl3 = new wxTextCtrl(botton,wxTE_MULTILINE|wxTE_DONTWRAP);
    wxBoxSizer* botomSizer = new wxBoxSizer(wxVERTICAL);

    botomSizer->Add(textCtrl3,wxSizerFlags(1).Expand().DoubleBorder(wxLEFT|wxRIGHT|wxBOTTOM));
    botton->SetSizer(botomSizer);

    // Add the top and bottom parts to the splitter,and set the sash gravity to
    // .5 so that both halfs will expand equally when the frame is resized.
    splitter->SplitHorizontally(top,botton);
    splitter->SetSashGravity(.5);

    Layout();
}

class MyApp : public wxApp
{
    public:
        virtual bool OnInit()
        {
            ::wxInitAllImageHandlers();
            MyFrame* frame = new MyFrame();
            frame->Show();
            return true;
        }
};

wxIMPLEMENT_APP(MyApp);

在Windows上，如下所示：

我还没有从CMake GUI框架中复制每个小部件，但是我认为这里有足够的信息来说明正在发生的事情。
