duilib设置窗口边框-Go服务器开发

在DuiLib中，可以通过设置窗口的样式来实现自定义窗口边框。以下是一个示例：

#include "DuiLib/UIlib.h"
using namespace DuiLib;
class MyWindow : public CWindowWnd, public INotifyUI
{
public:
    virtual LPCTSTR GetWindowClassName() const { return _T("MyWindow"); }
    virtual UINT GetClassStyle() const { return UI_CLASSSTYLE_FRAME | CS_DBLCLKS; }
    virtual void Notify(TNotifyUI& msg)
    {
        if (msg.sType == _T("click"))
        {
            if (msg.pSender->GetName() == _T("btnClose"))
                Close();
            else if (msg.pSender->GetName() == _T("btnMin"))
                SendMessage(WM_SYSCOMMAND, SC_MINIMIZE, 0);
        }
    }
    virtual LRESULT HandleMessage(UINT uMsg, WPARAM wParam, LPARAM lParam)
    {
        LRESULT lRes = 0;
        BOOL bHandled = TRUE;
        switch (uMsg)
        {
            case WM_CREATE:
                OnCreate(uMsg, wParam, lParam);
                break;
            case WM_NCACTIVATE:
                if (!::IsIconic(*this))
                    return (wParam == 0) ? TRUE : FALSE;
                break;
            case WM_NCCALCSIZE:
                if (!::IsIconic(*this))
                    return CWindowWnd::HandleMessage(uMsg, wParam, lParam);
                break;
            default:
                bHandled = FALSE;
                break;
        }
        if (bHandled)
            return lRes;
        return CWindowWnd::HandleMessage(uMsg, wParam, lParam);
    }
private:
    void OnCreate(UINT uMsg, WPARAM wParam, LPARAM lParam)
    {
        m_PaintManager.Init(m_hWnd);
        CDialogBuilder builder;
        CContainerUI* pRoot = static_cast<CContainerUI*>(builder.Create(_T("window.xml"), (UINT)0, NULL, &m_PaintManager));
        if (pRoot != NULL)
        {
            m_PaintManager.AttachDialog(pRoot);
            m_PaintManager.AddNotifier(this);
            CButtonUI* btnClose = static_cast<CButtonUI*>(m_PaintManager.FindControl(_T("btnClose")));
            if (btnClose != NULL)
                btnClose->SetVisible(true);
            CButtonUI* btnMin = static_cast<CButtonUI*>(m_PaintManager.FindControl(_T("btnMin")));
            if (btnMin != NULL)
                btnMin->SetVisible(true);
        }
    }
private:
    CPaintManagerUI m_PaintManager;
};
int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE /*hPrevInstance*/, LPSTR lpCmdLine, int nCmdShow)
{
    CPaintManagerUI::SetInstance(hInstance);
    CPaintManagerUI::SetResourcePath(CPaintManagerUI::GetInstancePath() + _T("\\resources"));
    MyWindow wnd;
    
    // 设置窗口样式，去掉默认边框
    DWORD dwStyle = WS_POPUP | WS_VISIBLE;
    ::CreateWindowEx(WS_EX_APPWINDOW, wnd.GetWindowClassName(), _T("DuiLib Custom Window Border"), dwStyle,
                     0, 0, 800, 600, NULL, NULL, hInstance, &wnd);
                     
    CPaintManagerUI::MessageLoop();
    return 0;
}
