easyx输出字符串在窗口上

在EasyX中，向窗口输出字符串通常涉及到在窗口的客户端区（Client Area）绘制文本。下面是一个简单的示例，展示如何在一个窗口上输出文本：

#include <easyx.h>

class MyWindow : public CWinApp {
public:
    void OnCreate() override {
        // 创建 EasyX 窗口
        CWindow win = Create("My Window", 0, WS_OVERLAPPEDWINDOW);
        
        // 设置字体和颜色
        HFONT hFont = win.CreateFont(16, 0, 0, 0, FW_NORMAL, FALSE, FALSE, FALSE,
                                      ANSI_CHARSET, OUT_TT_PRECIS, CLIP_DEFAULT_PRECIS,
                                      DEFAULT_QUALITY, FF_DONTCARE, "Arial");
        win.SelectObject(hFont);

        // 绘制字符串到窗口中心
        int centerX = win.Width() / 2;
        int centerY = win.Height() / 2;
        win.DrawText("Hello, EasyX!", centerX - (win.GetTextExtent("Hello, EasyX!")[0] / 2), centerY, DT_CENTER | DT_VCENTER);
    }
};

int WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int) {
    MyWindow app;
    return app.Run();
}
