获取非活动窗口缩略图预览

Question

Windows 7和Vista都有一个非常有用的功能：任务栏缩略图预览，它允许你查看其他（最小化窗口）上发生的事情。

我对使用Windows函数和DLL非常缺乏经验，但我想知道是否有可能获得最小化的Windows预览。目标是创建一个应用程序，该应用程序将在具有最小化窗口的所有进程之间循环。

不完全是你需要的，但是一个好的起点。这里

    #include <ITaskBarList.au3>
#include <ButtonConstants.au3>
$GUI = GUICreate("Thumbnail Button", 250, 100)
GUICtrlCreateButton('ThumbNailClip', 1, 1)
GUISetState(@SW_SHOW)
$oTaskbar = _ITaskBar_CreateTaskBarObj()
$but1 = _ITaskBar_CreateTBButton('Down ToolTip', @ScriptDir & 'IconsDown.ico', -1, '_Down_Button')
$but2 = _ITaskBar_CreateTBButton('Left ToolTip', @ScriptDir & 'IconsLeft.ico', -1, '_Left_Button')
$but3 = _ITaskBar_CreateTBButton('', @ScriptDir & 'IconsLeft.ico', -1, '_Right_Button');no tooltip
$but4 = _ITaskBar_CreateTBButton('Internet Explorer',@ProgramFilesDir & 'Internet Exploreriexplore.exe', -1, '_IE_Button');
$but5 = _ITaskBar_CreateTBButton('AutoIt', @AutoItExe, -1, '_AutoIt_Button');
_ITaskBar_AddTBButtons($GUI)
_ITaskBar_SetThumbNailToolTip($GUI, 'ITaskBarList UDF ToolTip Example')
; Set progressbar to normal state (green)
 _ITaskBar_SetProgressState($GUI, 2)
For $i = 1 to 100
    _ITaskBar_SetProgressValue($GUI, $i)
    Sleep(75)
    ; Set progressbar to Paused state (yellow). Notice that even thought the progressbar is in "paused" state, you can
    ; still can change the value. Its just an indicator. It doesnt actually pause anything.
    If $i = 25 Then _ITaskBar_SetProgressState($GUI, 8);
    ;Set progressbar to Error state (red). This works the same way as paused state. Its just an indicator.
    If $i = 50 Then _ITaskBar_SetProgressState($GUI, 4)
    ;Set progressbar back to normal state (green)
    If $i = 75 Then _ITaskBar_SetProgressState($GUI, 2)
Next
;set progressbar Indeterminate
_ITaskBar_SetProgressState($GUI, 1)
Sleep(3000)
;clear progressbar
_ITaskBar_SetProgressState($GUI)
;Set ThumbNail Preview to only show the button from the GUI
MsgBox(0,'SetThumbNailClip','Notice that the ThumbNail preview shows the whole GUI.', 30, $Gui)
_ITaskBar_SetThumbNailClip($GUI, 0, 0, 80, 30)
MsgBox(0,'SetThumbNailClip','Now look again. You should only see the ThumbNailClip Button', 30, $Gui)
; clear thumbnail clip
_ITaskBar_SetThumbNailClip($GUI)
;Add Icon Overlay
_ITaskBar_SetOverlayIcon($GUI, @ProgramFilesDir & 'Internet Exploreriexplore.exe')
MsgBox(0,'SetOverlayIcon','Taskbar tab should have and Internet Explorer icon overlay. ', 30, $Gui)
; clear icon overlay
_ITaskBar_SetOverlayIcon($GUI)
