音乐播放器（界面设计）学号：姓名： 1 功能介绍设计的音乐播放器是能够实现音乐的播放、暂停、声音控制、播放时间和歌曲的选择用户可以选择播放的音乐，播放器也可以显示该音乐的歌曲名以及歌曲的播放总时间，播放进度等歌曲的相关功能；用户还可以通过音乐增减按钮调节声音大小。2 各功能模块图音乐播放器声音控制停止重复隐藏播放暂停 3设计思想通过在IDD_MUSICPLAY_DIALOG 对话框中添加控件，并设置相应的属性值。并且为其添加进度条ID为：IDC_SLIDER1，音量控制ID为：IDC_SLIDER2一个大致的轮廓已经出来，没有类似酷我或天天静音的皮肤，但通过 LoadBitmap() 加载位图，来改变现在的外观，4 播放器界面的设计创建一个基于对话框的工程命名为MusicPlayer。并为对话框添加控制按钮用Photoshop为播放器设计一个背景图像并将其载入工程重载对话框的OnCtlColor()HBRUSH CMusicPlayerDlg:OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) HBRUSH hbr = CDialog:OnCtlColor(pDC, pWnd, nCtlColor);/ TODO: Change any attributes of the DC hereif( nCtlColor = CTLCOLOR_DLG)return m_brBack;/ TODO: Return a different brush if the default is not desiredreturn hbr;为播放器添加不规则个性按钮。轴线需要在对话框类中定义按钮的ID及按钮变量。enumMY_OPEN=1010,MY_PLAY=1011,MY_PAUSE=1012, MY_STOP=1013,MY_REPEAT=1014,MY_HIDE=1015, MY_EXIT=1016,MY_MIN=1017,MY_MAX=1018,MY_QUITE=1019;CMybutton m-Open,M-Play,m_Pause,m_Stop m-Repeat,m_Hide,Exit，m_Min,m_Max,m_Quite:在对话框的初始化框中创建这些按钮对象BOOL CMusicPlayerDlg:OnInitDialog()CDialog:OnInitDialog();/ Add About. menu item to system menu./ IDM_ABOUTBOX must be in the system command range.ASSERT(IDM_ABOUTBOX & 0xFFF0) = IDM_ABOUTBOX);ASSERT(IDM_ABOUTBOX AppendMenu(MF_SEPARATOR);pSysMenu-AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);/ Set the icon for this dialog.
