Is there a way to disable the windows "fade effect" for a particular GUI


Recommended Posts

Hi all,

Does anyone know if there is a way to disable the Windows "fade effect" that occurs when a window appears or disappears?

It is possible for a user to disable visual effects in windows in general through the system properties > performance settings, but I am interested just in fixing it for a particular window that pops up in my app.

I would like it to appear and disappear instantaneously, snapping in and out, out of nowhere, rather than the short (maybe 300 ms?) fade in/fade out effect that windows has.

Thanks for any tips

Do you mean something like this here?

;Coded by UEZ build 2019-02-05
#include <GUIConstantsEx.au3>
#include <WinAPISys.au3>

Global Const $iState = _WinAPI_GetGUIMinMaxAnim()

If $iState Then _WinAPI_SetGUIMinMaxAnim(0)

Global $hGUI = GUICreate("No min/max GUI anim")
GUISetState()

Do
Until GUIGetMsg() = $GUI_EVENT_CLOSE

If $iState Then _WinAPI_SetGUIMinMaxAnim(1)


Func _WinAPI_SetGUIMinMaxAnim($bAnim = 0)
    $bAnim = ($bAnim < 0) ? 0 : ($bAnim > 1) ? 1 : $bAnim
    Local Const $SPIF_SENDCHANGE = 0x02, $SPI_SETANIMATION = 0x0049
    Local $tANIMATIONINFO = DllStructCreate("uint cbSize;int iMinAnimate")
    $tANIMATIONINFO.cbSize = DllStructGetSize($tANIMATIONINFO)
    $tANIMATIONINFO.iMinAnimate = $bAnim
    Return _WinAPI_SystemParametersInfo($SPI_SETANIMATION, 0, $tANIMATIONINFO, $SPIF_SENDCHANGE)
EndFunc   ;==>_WinAPI_SetGUIMinMaxAnim

Func _WinAPI_GetGUIMinMaxAnim()
    Local Const $SPIF_SENDCHANGE = 0x02, $SPI_GETANIMATION = 0x0048
    Local $tANIMATIONINFO = DllStructCreate("uint cbSize;int iMinAnimate")
    $tANIMATIONINFO.cbSize = DllStructGetSize($tANIMATIONINFO)
    _WinAPI_SystemParametersInfo($SPI_GETANIMATION, $tANIMATIONINFO.cbSize, $tANIMATIONINFO)
    Return $tANIMATIONINFO.iMinAnimate
EndFunc   ;==>_WinAPI_GetGUIMinMaxAnim

 

Tested only on Win10.

 

Edit: it seems that this function influences all GUI behavior and not only the created GUI. I can remember that there is a code only for the created GUI but I cannot find it at the moment.

UEZ, your code worked perfectly, thanks so much. As you noted it affects all GUIs and not just the one being created so that is a limitation. I guess the solution to that would be to retrieve the state of the windows settings that the script affects before changing them, make the GUI, then restore the settings. Maybe do this again when the window is being dismissed. A little brute force but would work I think.

Orbs, would this actually bring up the window faster? Users are going to be repeatedly running this tool throughout the day and I want to make it as snappy as possible, shaving off even 1/3 of a second from start and quit by removing the fade-in and fade-out. I will give that a try (WinSetTrans(0), and WinSetTrans(255)). It seems to me that that would remove the fade effect but not actually shave off 2/3 a second from the launch-use-quit cycle. However even a perception of being faster may improve the UX. :) So it may be worth doing nonetheless.

Correct me if Im wrong but it seems to me that the UEZ method may actually shave 2/3 of a second off the total use experience per activation, whereas the WinSetTrans method may (hopefully) make it feel snappier potentially but not actually shave off time. Am I correct?

Thanks

I updated the code from post#2.

      I'm trying to assign a faint text in the background to an input field that disappears after the input has started. This should have a certain color such as gray.

      Hi All, 
      I am trying to mark out the middle square of this Magnify Routine "window on right" (stolen from M23 - Thanks) - I assume the DllCall is overwriting the boxes. But wherever I try and redraw, they won't stay on the Magnify Window. Can anyone advise, bet way to keep boxes around the middle square.
      Please be kind with my code, it is ripped from a MUCH bigger exe.
      The "half" transparent window, is for dragging to where you want it, and the buttons are for more precise placement.

      Hi all,
      I am creating a GUI library in Nim with win32 API functions. Even though the syntax is similar to Python, coding is almost similar to C in Nim. 
      I can change the back color of the button in NM_CUSTOMDRAW. But I can't change the button text color. here is my pseudo code.  
      proc setBtnBackColor*(me : Button, lp: LPNMCUSTOMDRAW ) = if lp.uItemState and CDIS_SELECTED : #------------------ btn clicked # Here i am changing the button color with SelectObject & FillRect. elif lp.uItemState and CDIS_HOT : # ----------------Mouse over # Here i am changing the button's mouse hover color with SelectObject & FillRect. else: # -------------------------Default color set # Here i am changing the button's default color with SelectObject & FillRect. # Here i tried---> SetTextColor(lp.hdc, RGB(102, 255, 51) ) #------- But no luck. #------------------------------------------------------------------------- Please guide me. What i am doing wrong here ?  I am returning "CDRF_SKIPDEFAULT" after calling this function.
      Note : I am using subclassed button. So when the parent window receives WM_NOTIFY message, it sends that to my button's WndProc. There i am handling the message.

      I use SetSoundDevice to control my audio devices but the UI was either
       
      blurry like this:

      And now it looks good: 
      but it doesn't work on everything, for example the "GUICtrlCreateLabel("Output type: ", 30, 130, 65, 20) ;, $SS_RIGHT)" (from the autoit3wrapper gui)
      because the comment contains a parenthesis and it would break completely if there were variables as parameters..
      Is there some kind of parser around that I could use instead or maybe someone who has already done something like this?
