Set a semi transparent background on second/child window

5 posts in this topic

I would like to create a window like the one shown below. The requirements are as below

1. The title bar should be opaque.

2. The parent window/Main screen will be below the side menu/child window

3. The left side of the side menu window should be opaque.

4. The right side should be semi-transparent.

@siva1612 a simple search of the forum for "gui transparency" turns up a large number of threads on the subject. What have you tried on your own?

@JLogan3o13 I have tried the following.

All the threads I searched were talking either about setting the background as completely transparent or setting the transparency of the entire window including the controls and all. None of these worked.

Though as I'm writing this reply i think can achieve this effect by using two GUIs. One on the left with an opaque background and one on the right without any controls and with its transparency level set. Will try that!

Here is an alternative approach. Click the button to show the overlay.

It uses a semi-transparent GUI with no controls as the 'background'.
The front GUI has the controls with a background that is completely transparent.

 

#include <GUIConstants.au3>
#include <WinAPI.au3>
#include <FontConstants.au3>
#include <AutoItConstants.au3>

Opt("GUIOnEventMode", 1)

Global $hgui, $hguiovl, $hguiovlbk
Global $showOverlay

;run main function
_main()

Func _main()
    Local $iGuiWidth = 500
    Local $iGuiHeight = 400
    Local $bkColor = 0x555555
    Local $alpha=200 ;0-255
    Local $iOverlayX = 150

    ;create the main GUI
    $hgui = GUICreate("main gui", $iGuiWidth, $iGuiHeight, -1, -1, -1, BITOR($WS_EX_COMPOSITED,$WS_EX_LAYERED))
    GUISetBkColor( 0x99FF99 )
    GUISetOnEvent($GUI_EVENT_CLOSE, "_onExit")

    GUICtrlCreateLabel("This is some text on bottom", 300, 150, 200)
    GUICtrlSetColor(-1, 0x000000)
    GUICtrlCreateLabel("show/hide overlay", 10, 30, 200)
    GUICtrlSetColor(-1, 0x000000)
    GUICtrlCreateButton("Show", 10, 50, 50, 25)
    GUICtrlSetOnEvent(-1, "_showoverlay")

    ;create the overlay background GUI
    $hguiovlbk = GUICreate("transparency test bk", $iGuiWidth-$iOverlayX, $iGuiHeight, $iOverlayX, 0, $WS_POPUP, BITOR($WS_EX_COMPOSITED,$WS_EX_LAYERED, $WS_EX_MDICHILD), $hgui)
    GUISetBkColor( $bkColor )
    WinSetTrans($hguiovlbk,"", $alpha) ;make window semi-transparent
    GUISetOnEvent($GUI_EVENT_CLOSE, "_onExit")

    ;create the overlay controls GUI
    $hguiovl = GUICreate("transparency test", $iGuiWidth-$iOverlayX, $iGuiHeight, $iOverlayX, 0, $WS_POPUP, BITOR($WS_EX_COMPOSITED,$WS_EX_LAYERED, $WS_EX_MDICHILD), $hgui)
    GUISetBkColor( $bkColor )
    _WinAPI_SetLayeredWindowAttributes($hguiovl, $bkColor, 255) ;make background fully transparent
    GUISetOnEvent($GUI_EVENT_CLOSE, "_onExit")
    GUISetFont(Default, Default, Default, "Arial", $hguiovl, 3 ) ;disable aliasing for fuzzy fonts

    GUICtrlCreateLabel("This is some text on top", 10, 10, 200)
    GUICtrlSetColor(-1, 0xFFFFFF)
    GUICtrlSetFont(-1, 12)

    GUICtrlCreateLabel("This is some more text on top", 10, 50, 200)
    GUICtrlSetColor(-1, 0xFFFFFF)
    GUICtrlSetFont(-1, 12)

    GUISetState(@SW_SHOW, $hgui)

    While 1
        Sleep(100)
    WEnd
EndFunc

Func _showOverlay()
    If $showOverlay Then
        GUISetState(@SW_HIDE, $hguiovlbk)
        GUISetState(@SW_HIDE, $hguiovl)
        $showOverlay = 0
    Else
        GUISetState(@SW_SHOW, $hguiovlbk)
        GUISetState(@SW_SHOW, $hguiovl)
        $showOverlay = 1
    EndIf
EndFunc

Func _onExit()
    Exit
EndFunc

      MS Splash Screens
      The office 2016/17 office suite has made many people turn heads with its functions and especially their splash screen.
      I now present to you, the MS Style Splash Screen. For Rookies, Novices and anyone who wants a ready made splash screen for your gui application.

      You can now download it and also try it out yourself.
      You have three colors to choose from:
      Blue
      Red
      Green
      All three colours are from the famous programs.
      I also included the KODA form to you can have freedom with this splash screen.
      Note: the KODA form does not have the three colours as well as the correct blue. 

      Have fun and enjoy.
      Note:
      I will update the splash to add the automated 3 dots animation at a later stage.

      A gui splash screen. Themed after the famous MS Office Suite.
      Three colours to choose from, Red, Blue and Green.
      You can change the labels to your own application.

      Also bundled with this is the KODA form. So you can open up and see the basic structure of this splash screen.

      Hello all,
      I've been trying to figure out how to launch Google Chrome in the background (hidden) but it doesn't seem possible. I've tried the following methods:
      ShellExecute("C:\Program Files (x86)\Google\Chrome\Application\chrome.exe", "", "", "", @SW_HIDE) Also I've tried:
      ShellExecute(@ComSpec, "/c start chrome.exe","","",@SW_HIDE) Lastly I tried:
      RunWait('"'&@ProgramFilesDir&'\Google\Chrome\Application\chrome.exe" --silent-launch',@ScriptDir)  
      But all of them launch my chrome browser without hiding it. Does anyone know a workaround for this or if AutoIT just can't Chrome? 
      Bonus points if you know how to make it launch chrome hidden and make it go to https://www.autoitscript.com
       
      Thank you,

      I have a working program currently driven largely through menu selections. I would like to add a toolbar where most of the tollbar button actions are basically the same as menu items, but quicker to access. I have been wading around in toolbar examples, MSDN pages etc, it's clearly going to be a bit of a slog to get everything right, including tooltips etc. I thought I would start with something simple to prove the principle.
      Using bits from the help file examples I have a small program that successfully displays a toolbar. However, what seemed like the most elegant way to deal with the button commands does not seem to work. My understanding was that a toolbar button fires a WM_COMMAND message, with the command Id set by the second parameter in the call to
      _GUICtrlToolbar_AddButton ( $hWnd, $iID, $iImage)
      so I though it would be a good idea to set this Id to the same value as my menu item Id; then it would run the same task which is what I wanted. This did not work. I am using message loop mode and would like to stick with this because some of my scripts run hardware at the same time as the gui; it is easier if I don't have to worry about code being interrupted with the hardware in an unknown state . So I added a handler for WM_COMMAND, with some cribbed display code to try and see why. The toolbar button defintely fired a WM_COMMAND message and the Id looked the same, so no explanation there.
      I guess the issue is with GUIGetMsg() which may be constructed to ignore all but a limited number of control handles, i.e. those made with the GuiCtrlCreate... commands; this is speculation.
      I would dearly love to find a tidy way to get around this. Having some controls handled in the message loop and some in a WM_COMMAND handler, performing the same task, feels ugly. I would be very grateful for further insight from someone experienced with handling a toolbar. Perhaps I should be trying to fire the menu item. I have attached a code snippet to try and illustrate the issue.

      Hello all,
      I've been working on 4 standalone scripts. They each have their own GUI and are now independent .exe's. But instead of having 4 separate icons on my computer, is it possible to put them all together into one .exe?
      What I want is one interface with tabs. Each script's GUI would be on their own respective tab. Is this possible?
      The different scripts don't need to communicate with one another. I just want them all in one .exe.
      I can't find this anywhere... Any help would be greatly appreciated. Thank you!
