小弟我的上面这种方法有缺陷

1:不是浮动窗口,
2:不是最顶层,
3:自动宽、高控制得不是好，
4：...还有的其它,就请各位朋友帮帮小弟我了,

大家一起进步,才是真正的进步!

楼上各位好,我来了,我说的那个问题于3月底完成了,已经给客户用了.
我要实现的功能是:当鼠标单击数据窗口,且有数据时,就调用函数显示信息.
方法是:用个Edit模仿Delphi中的Hint.
函数:返回值类型:integer,
参数1:Window->w_window 参数2:datawindow->dw_source 参数3:multilineedit-->m_edit
参数4:integer->is_x 参数5:integer->is_y 参数6:is_row
代码如下:
int i,j,numbertemp,ii,npoint
string bands,obj_clicked,str,str1,str2,str3,str4,coltype,title
datetime timetemp
date datetemp
string a,b,aa,bb
m_edit.x= dw_source.x +dw_source.pointerx()+50// is_x
m_edit.y= dw_source.y +dw_source.pointery()+50//is_y - 10
if m_edit.y + m_edit.height>=w_window.height then
m_edit.y= w_window.height - m_edit.height - 100
m_edit.SetRedraw(true)
for i=1 to long(dw_source.object.datawindow.column.count)
a="#"+ string(i) +".name"
b = dw_source.Describe(a)
aa="#"+ string(i) +".visible"
bb=dw_source.describe(aa)
if bb='0' then continue
str2="#" + string(i)+".dbname"
str3 = dw_source.Describe(str2)
npoint=pos(str3,'.')
if npoint>0 then str3=replace(str3,npoint,1,'_')
coltype=dw_source.Describe(b + ".ColType")
title=dw_source.Describe(str3 + "_t.text")
if title='!' then
title=dw_source.Describe(b + "_t.text")
end if
if title='!' then
title=b
end if
if len(coltype)<2 then continue
if lower(left(coltype,8)) ='datetime' then
str1=string(dw_source.getItemDateTime(is_row,i))
if str1='' or isnull(str1) then str1=' '
str=str+"【" + title + "】 " +str1+char(13)+char(10)
str1=' '
elseif lower(left(coltype,4))='char' then
str1=dw_source.getitemstring(is_row,i)
if str1='' or isnull(str1) then str1=' '
str=str+"【" + title + "】 " +str1+char(13)+char(10)
str1=' '
elseif lower(left(coltype,4))='long' or
lower(left(coltype,4))='real' or
lower(left(coltype,4))='inte' or
lower(left(coltype,4))='doub' or
lower(left(coltype,4))='deci' or
lower(left(coltype,4))='numb' then
str1=string(dw_source.getitemnumber(is_row,i))
if str1='' or isnull(str1) then str1=' '
str=str+"【" + title + "】 " +str1+char(13)+char(10)
str1=' '
elseif lower(left(coltype,4))='date' and
lower(left(coltype,8)) <>'datetime' then
str1=string(dw_source.getitemdate(is_row,i))
if str1='' or isnull(str1) then str1=' '
str=str+"【" + title + "】 " +str1+char(13)+char(10)
str1=' '
end if
coltype=''
next
m_edit.height=m_edit.linecount()*65
m_edit.text=str
m_edit.visible = TRUE
return 0

这个链接的代码有点问题，就是鼠标事件的处理中，第一次点击没问题，但第二此没有反映，第三次没问题，依次类推！！！

就用PB本身的东西，完全可以实现，在陶清网站上有源代码，你搜索一下，我原来下载过，只是手头没有带。
原理很简单，就是在你需要显示的控件的mousemove中写代码，控制你那个提示文本框是否显示，以及显示的位置。一旦鼠标移开，就隐藏

同意楼上的观点，pb8已经支持这种功能了，不用在写代码了把

图标？
图片按钮和图片控件都有一个powertiptext属性，在此输入你想要显示得信息，在程序中鼠标放在控件上就显示。
如果是工具栏上得图标，可以设置toolbar的microhelp，也可以显示信息。

不是有个mousemove事件中吗
你可以在那里写代码了

csdn禁止连续回复三次，所以都没机会说明一下，代码针对的是pb65，8以上就支持了，因此，是帮助继续使用pb65的苦难兄弟的。
