Directui Study notes 2-dui Hellowworld Program

After the last chapter of the configuration, we have a duilib environment, now we can start to write a DUI program.

If you do not yet how to download and configure Duilib, please visit the DIRECTUI study Note 1-Source download and environment configuration

A: We create a new class to inherit the base class that DUI provides to us

#include pragma once#include<UIlib.h>//If you attach the directory to the correct settings, you will not find it hereusing namespaceDuilib;//The following preprocessing directives are used to determine whether the project uses Unicode with corresponding LIB libraries for debug in release#ifdef _debug# ifdef _unicode# pragma comment (lib,"Duilib_ud.lib")#   Else# pragma comment (lib,"Duilib_d.lib") # endif#else# ifdef _unicode# pragma comment (lib,"Duilib_u.lib")#   Else# pragma comment (lib,"DuiLib.lib") # endif#endifclassCmyduiwnd: PublicCwindowwnd, Publicinotifyui{ Public: Cmyduiwnd () {}~Cmyduiwnd () {}//Getwindowclassname is a pure virtual function of the base class and must be implemented after we inherit it.     VirtualLPCTSTR Getwindowclassname ()Const{return_t ("Duimainframe"); }    //overriding a virtual function of a base class the following 2 are    Virtual voidNotify (tnotifyui&msg) {}    VirtualLRESULT handlemessage (UINT umsg, WPARAM WPARAM, LPARAM LPARAM) {LRESULT lres=0; if(umsg = = wm_create)//If a window creates a message        {            //Create a buttonCcontrolui *pbutton =NewCbuttonui; PWnd->settext (_t ("Hello world!"));//Set TextPwnd->setbkcolor (0xffff0000);//set a gray backgroundM_paintmanager.init (m_hwnd);            M_paintmanager.attachdialog (Pbutton); returnLres; }        if(M_paintmanager.messagehandler (umsg, WParam, LParam, lres))returnLres; return__super::handlemessage (umsg, WParam, LParam); }    

B: The code in the main function

int int ncmdshow) {    cpaintmanagerui::setinstance (hinstance);
    Cmyduiwnd Framewnd;    Framewnd (NULL, _t ("directui"), Ui_wndstyle_frame, Ws_ex_windowedge);    Framewnd.showmodal ();
    Framewnd.centerwindow ();
　　    return 0 ;}

C: Post-run effects
