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，可以让您查看其他（最小化窗口）上发生的情况。

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。目标是制作一个可以在所有具有最小化窗口的进程之间循环的应用程序。

不完全是您所需要的，但它是一个很好的起点。 HERE

    #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 & '\Icons\Down.ico', -1, '_Down_Button')
$but2 = _ITaskBar_CreateTBButton('Left ToolTip', @ScriptDir & '\Icons\Left.ico', -1, '_Left_Button')
$but3 = _ITaskBar_CreateTBButton('', @ScriptDir & '\Icons\Left.ico', -1, '_Right_Button');no tooltip
$but4 = _ITaskBar_CreateTBButton('Internet Explorer',@ProgramFilesDir & '\Internet Explorer\iexplore.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 Explorer\iexplore.exe')
MsgBox(0,'SetOverlayIcon','Taskbar tab should have and Internet Explorer icon overlay. ', 30, $Gui)
; clear icon overlay
_ITaskBar_SetOverlayIcon($GUI)
