【PPT 中也能实现图片的拖动功能】 本文档内包括两种方法来实现 现对 PPT 中如何实现:当播放 PPT 时,能够随意拖动图片到指定位置(补充:通过插入制作好的 FLASH 也可以实现这样的效果,后续有时间了会接着发布的,敬请期待)。、 一、通过宏实现 PPT 中图片的拖动功能 此处建议将宏的安全级别设置为低。 1.打开你要设置图片拖动功能的 PPT。 2.点击菜单:“工具——宏——宏”,出现对话窗口。 3.填写对话窗口中的“宏名”,宏名可以随意命名,比如:wantmove,再点“创建”,就进入代码模 式。 4.删去所看到的所有的代码,然后把下面的代码全拷贝进去。 Option Explicit Declare Function GetKeyState Lib "user32" (ByVal nVirtKey As Long) As Integer Private Declare Function WindowFromPoint Lib "user32" (ByVal xPoint As Long, ByVal yPoint As L ong) As Long Private Declare Function GetWindowRect Lib "user32" (ByVal hwnd As Long, lpRect As RECT) As Long Private Declare Function GetCursorPos Lib "user32" (lpPoint As PointAPI) As Long Private Declare Function SetCursorPos Lib "user32" (ByVal x As Long, ByVal y As Long) As Long Public Declare Function MonitorFromPoint Lib "user32.dll" (ByVal x As Long, ByVal y As Long, By Val dwFlags As Long) As Long Private Declare Function GetSystemMetrics Lib "user32" (ByVal nIndex As Long) As Long Private Const SM_SCREENX = 0 Private Const SM_SCREENY = 1 Private Const sigProc = "Drag & Drop" Public Const VK_SHIFT = &H10 Public Const VK_CTRL = &H11 Public Const VK_ALT = &H12 Private Type PointAPI x As Long y As Long End Type Public Type RECT Left As Long Top As Long Right As Long Bottom As Long End Type Public mPoint As PointAPI, dPoint As PointAPI Public ActiveShape As Shape Dim dragMode As Boolean Dim dx As Double, dy As Double Sub DragandDrop(sh As Shape) dragMode = Not dragMode If dragMode Then Drag sh End Sub Private Sub Drag(sh As Shape) Dim i As Integer, sx As Integer, sy As Integer Dim mWnd As Long, WR As RECT dx = GetSystemMetrics(SM_SCREENX): dPoint.x = dx dy = GetSystemMetrics(SM_SCREENY): dPoint.y = dy GetCursorPos mPoint With ActivePresentation.SlideShowWindow mWnd = WindowFromPoint(mPoint.x, mPoint.y) GetWindowRect mWnd, WR sx = WR.Left sy = WR.Top dx = (WR.Right - WR.Left) / ActivePresentation.PageSetup.SlideWidth dy = (WR.Bottom - WR.Top) / ActivePresentation.PageSetup.SlideHeight End With If dx > dy Then sx = sx + (dx - dy) * ActivePresentation.PageSetup.SlideWidth / 2 dx = dy End If If dy > dx Then sy = sy + (dy - dx) * ActivePresentation.PageSetup.SlideHeight / 2 dy = dx End If While dragMode GetCursorPos mPoint sh.Left = (mPoint.x - sx) / dx - sh.Width / 2 sh.Top = (mPoint.y - sy) / dy - sh.Height / 2 DoEvents i = i + 1: If i > 2000 Then dragMode = False: Exit Sub Wend End Sub 5.点击“保存”后,关闭代码模式,回到 ppt 设计页面。在你需要拖动的图片上鼠标右击,选择“动作 设置——单击鼠标——运行宏——确定”! 6.放映幻灯片,看看效果吧。 拖动图片方式:播放 PPT,在图片上单击鼠标,放开后,图片就随你鼠标移动,如果你再单击鼠标,图 片就停在你单击的地方。 二、通过 VBA 编实现 PPT 中图片的拖动功能 此处建议将宏的安全级别设置为低。 1.在演示文稿插入图像控件(视图——工具栏——控件工具箱),打开属性窗口,将 picture 设成你想 拖动的图片(图片大小要根据实际情况进行调整),遗憾的是 Image 控件不支持透明。 2.双击图像控件,打开的 VBA 编辑窗口(注意双击后先删除所有代码),复制下面的代码: Dim X1, Y1 As Integer Dim Down As Boolean Private Sub Image1_MouseDown(ByVal Button As Integer, ByVal Shift As Integer, ByVal X As Singl e, ByVal Y As Single) If Not Down Then X1 = X Y1 = Y Down = True End If End Sub Private Sub Image1_MouseMove(ByVal Button As Integer, ByVal Shift As Integer, ByVal X As Singl e, ByVal Y As Single) If Down Then Image1.Left = Image1.Left + X - X1 Image1.Top = Image1.Top + Y - Y1 X1 = X Y1 = Y End If End Sub Private Sub Image1_MouseUp(ByVal Button As Integer, ByVal Shift As Integer, ByVal X As Single, ByVal Y As Single) Down = False SlideShowWindows(1).View.First End Sub 3.保存,关闭 VBA 编辑窗口,放映幻灯片,即可看效果了。 4.如果你想拖动多张图片,如法炮制,复制上面的三个鼠标事件,修改 Image
