Python怎么使用拖拽文件相关的Windows API？

[随风而行lulu]

用Tkinter写了一个GUI程序。没实现文件拖放，网上搜索到几个拖放的资料

#coding:gbk
from Tkinter import *
import win32gui
import win32ui
import win32api
import win32con

class App(Frame):
    def __init__(self, master):
        Frame.__init__(self, master=master)
        self.master.title('note')
        self.top=self.winfo_toplevel()
        self.master=master
        self.files=[]
        self.mkwidgets()
        self.master.protocol('WM_DROPFILES', self.OnDropFiles)
        self.master.geometry('%dx%d+%d+%d' % (400,200,50,50))

        #以下代码参考：
        #http://bytes.com/topic/python/answers/855640-hooking-windowsmessages-python

        self.hwnd = eval(self.master.wm_frame())
        #toplevel.wm_frame():Return identifier for decorative frame of this widget if present.

        print 'hwnd:%s, title:%s' % (self.hwnd, win32gui.GetWindowText(self.hwnd))
        #title为空

        #设置窗口允许接收拖放的文件
        win32gui.DragAcceptFiles(self.hwnd, 1)

        self.wnd = win32ui.CreateWindowFromHandle(self.hwnd)
        #win32ui模块的方法，而非win32gui
        self.wnd.HookMessage(self.OnDropFiles, win32con.WM_DROPFILES)
        #上面这句和下面这句有什么区别？
        #self.master.protocol('WM_DROPFILES', self.OnDropFiles)
        #为什么捕获不到WM_DROPFILES消息？

    def mkwidgets(self):
        self.e=Entry(self.top)
        self.e.pack()
        self.b=Button(self.top, text='hi', command=self.click)
        self.b.pack()
        #self.after_idle(self.bindx)

    def click(self):
        print self.files
        self.hwnd = eval(self.master.wm_frame())
        print 'hwnd:%s, title:%s' % (self.hwnd, win32gui.GetWindowText(self.hwnd))

    def OnDropFiles(self,msg=None):
        #响应拖放消息的方法
        #这个方法从来没有被执行
        print 'Drag and drop'

        filenamebuffering=''
        #获取拖放的文件总数
        #hDropInfo=msg[2]
        hDropInfo=win32con.WM_DROPFILES
        #filescount = win32gui.DragQueryFile(win32con.WM_DROPFILES, 0xFFFFFFFF, None, 0)
        filescount = win32api.DragQueryFile(win32con.WM_DROPFILES, 0xFFFFFFFF, None, 0)
        #filescount = win32api.DragQueryFile(hDropInfo)

        for i in range(filescount):
            #获取文件名
            #filename=win32gui.DragQueryFile(hDropInfo, i, filenamebuffering, 100)
            filename=win32api.DragQueryFile(hDropInfo, i, filenamebuffering, 100)
            #filename=win32api.DragQueryFile(hDropInfo, i)
            #保存文件名
            self.files.append(filename)
        #清除缓存
        win32gui.DragFinish(hDropInfo)
        return 0

    app=App(root)
    #Entry(root).pack()
    app.mainloop()
        
'''关于HookMessage还有一个相关的网页，里面的代码如下

不知道楼主引用了那些帖子,我看论坛上面有介绍用tkdnd插件的. https://mail.python.org/pipermail/tkinter-discuss/2005-July/000476.html 有时间我试试,也和楼主分享一下.

[sprawling]

真的可以.我试过了,能拖进去,楼主可以参考一下.

[随风而行lulu]

帮忙看下，求大神支招

我搜索Tkinter 拖放，没有一个结果提到Tkdnd 。我在so上面找了个例子

[StaticTemp]

我认为这篇文章讲得更简单实用。http://blog.csdn.net/eijnew/article/details/6695271#comments
