Windows平台搭建wxWidgets 3.2.3开发环境

news2024/11/16 7:51:21

一.基础环境和使用的软件

操作系统:win11
mingw工具集:i686-8.1.0-release-win32-sjlj
IDE:clion
wxWidgets头文件:wxWidgets-3.2.3-headers
wxWidgets库文件:wxMSW-3.2.3_gcc810_ReleaseDLL

PS:

失败很多次才在网上看到, wxWidgets是挑mingw版本的.gcc用8.1,DLL就要用8.1

官网解释:

要在系统环境PATH设置mingw的路径

二.解压文件

将头文件和库文件解压到一个文件夹,目录如下:

ProjectRoot
├─dll
│ └─xxx.dll
└─include
    ├─msvc
    │ └─wx
    └─wx
        ├─xxx.h

三.创建main.cpp和CMakeLists.txt

main.cpp使用官方案例,代码如下:

// Start of wxWidgets "Hello World" Program
#include <wx/wx.h>
#include "windows.h"
class MyApp : public wxApp
{
public:
    bool OnInit() override;
};

wxIMPLEMENT_APP(MyApp);

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

private:
    void OnHello(wxCommandEvent& event);
    void OnExit(wxCommandEvent& event);
    void OnAbout(wxCommandEvent& event);
};

enum
{
    ID_Hello = 1
};

bool MyApp::OnInit()
{
    MyFrame *frame = new MyFrame();
    frame->Show(true);
    return true;
}

MyFrame::MyFrame()
        : wxFrame(nullptr, wxID_ANY, "Hello World")
{
    wxMenu *menuFile = new wxMenu;
    menuFile->Append(ID_Hello, "&Hello...\tCtrl-H",
                     "Help string shown in status bar for this menu item");
    menuFile->AppendSeparator();
    menuFile->Append(wxID_EXIT);

    wxMenu *menuHelp = new wxMenu;
    menuHelp->Append(wxID_ABOUT);

    wxMenuBar *menuBar = new wxMenuBar;
    menuBar->Append(menuFile, "&File");
    menuBar->Append(menuHelp, "&Help");

    SetMenuBar( menuBar );

    CreateStatusBar();
    SetStatusText("Welcome to wxWidgets!");

    Bind(wxEVT_MENU, &MyFrame::OnHello, this, ID_Hello);
    Bind(wxEVT_MENU, &MyFrame::OnAbout, this, wxID_ABOUT);
    Bind(wxEVT_MENU, &MyFrame::OnExit, this, wxID_EXIT);
}

void MyFrame::OnExit(wxCommandEvent& event)
{
    Close(true);
}

void MyFrame::OnAbout(wxCommandEvent& event)
{
    wxMessageBox("This is a wxWidgets Hello World example",
                 "About Hello World", wxOK | wxICON_INFORMATION);
}

void MyFrame::OnHello(wxCommandEvent& event)
{
    wxLogMessage("Hello world from wxWidgets!");
}

CMakeLists.txt代码如下:

cmake_minimum_required(VERSION 3.26)
project(wxWidgets_test)
include_directories(${PROJECT_SOURCE_DIR}/include)#设置头文件目录
link_directories(${PROJECT_SOURCE_DIR}/dll)#设置库文件目录
set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/dll)#设置EXE生成目录
add_executable(main main.cpp)
target_link_libraries(main wxbase32u_gcc810.dll wxmsw32u_core_gcc810.dll)#链接动态库
