VC之按钮控件位置大小界面设置

本文简单介绍下按钮控件的位置大小和界面设置。

首先，新建一个对话框应用程序，并且在界面上添加几个按钮

然后，设置贴图按钮的属性

添加图片资源

 

将第一个图片加载到程序资源中，第二个图片放在资源文件夹中

接着，添加按钮相关变量

CButtonSTm_btn5;CBitmapButtonm_btn4;CBitmapButtonm_btn3;

然后处理

void CButtonUiDlg::SetButtonUI(){//button1 do nothing//button2 set size and positionRECT clientRect;clientRect.left = 200;clientRect.top = 100;clientRect.right = clientRect.left + 100;clientRect.bottom = clientRect.top + 100;GetDlgItem(IDC_BUTTON2)->MoveWindow(&clientRect);//button3 set background get from resourcem_btn3.LoadBitmaps(IDB_BITMAP1);//button4 set background get from file pictureCString sCurrentPath = "";char Path[270];DWORD len = 0;DWORD i = 0;len = GetCurrentDirectory(270,Path);for(i=0;i<len;i++){sCurrentPath = sCurrentPath + CString(Path[i]);}sCurrentPath = sCurrentPath + "/res";CString sFilePathName = sCurrentPath + "/bg2.bmp";m_btn4.LoadBitmaps(sFilePathName);//button5 set background from classm_btn5.SetBtnCursor();m_btn5.SetIcon(m_hIcon);m_btn5.SetTooltipText(&sFilePathName);}

运行程序，查看效果

其中，按钮5使用的类CButtonST来源于网络，附件如下
