GuiRegisterMsg not Working for $WM_LBUTTONDBLCLK

[Rat]

Dear AutoIt People,

I have a script where I am attempting to create an event handler for the left mouse button double click event. I have confirmed that the "GuiRegisterMsg" call is successful, but the event handler is never called?

The event handler is registered as follows:

GuiRegisterMsg($WM_LBUTTONDBLCLK, "doLButtonDblClk")  ; Register an event handler for the Left Mouse Button Double-Click message

And the actual event handler looks like this:

Func doLButtonDblClk($hWnd, $Msg, $WParam, $LParam)
    $X = BitShift($LParam, 16)
    $Y = BitAND($LParam, 0xFFFF)
MsgBox(0, 'Debug', 'X = ' & $X & @CRLF & 'Y = ' & $Y)

    If $X >= $LogoLeft And $X <= $LogoLeft + $LogoWidth And $Y >= $LogoTop And $Y <= $LogoTop + $LogoHeight Then
MsgBox(0, 'Debug', 'Hit In Logo')
        WinSetOnTop($LongName, '', 0)  ; Un-Pin the Window from the top of the Z-Order (Technician can do this after remoting in)
        $PinWindow = False
        Return 0  ; Disable any further event handling of this message
    EndIf
EndFunc

Cheers,

Rat ^^>//o

Rat,

Welcome to the AutoIt forum.

There is a major problem with your message handler - it contains a couple of blocking functions.

As the Help file says:

"Warning: blocking of running user functions which executes window messages with commands such as "Msgbox()" can lead to unexpected behavior, the return to the system should be as fast as possible !!!"

So it is hardly unexpected that you are not getting what you want. Try replacing the MsgBoxes with ConsoleWrites - this works fine for me:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

Global $LogoLeft = 0, $LogoWidth = 100, $LogoTop = 0, $LogoHeight = 100

$hGUI = GUICreate("Test", 500, 500)

GUISetState()

GUIRegisterMsg($WM_LBUTTONDBLCLK, "doLButtonDblClk") ; Register an event handler for the Left Mouse Button Double-Click message

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch

WEnd

Func doLButtonDblClk($hWnd, $iMsg, $wParam, $lParam)

    $X = BitShift($LParam, 16)
    $Y = BitAND($LParam, 0xFFFF)
    ConsoleWrite('X = ' & $X & @CRLF & 'Y = ' & $Y & @CRLF)

    If $X >= $LogoLeft And $X <= $LogoLeft + $LogoWidth And $Y >= $LogoTop And $Y <= $LogoTop + $LogoHeight Then
        ConsoleWrite("Hit in Logo" & @CRLF)
        ;WinSetOnTop($LongName, '', 0) ; Un-Pin the Window from the top of the Z-Order (Technician can do this after remoting in)
        ;$PinWindow = False
        Return 0 ; Disable any further event handling of this message
    EndIf

EndFunc   ;==>doLButtonDblClk

Hi M23,

Thanks for you prompt reply. I did notice that bit about blocking functions in the help doc... but ony added the MsgBox() calls for debugging when I didn't appear to be handling the double click event. I took them back out but I am still not handling the event, (ie. the window isn't becoming un-pinned).

I've included the entire script below:

I fail to see where and how $PinWindow resolves to True in your code. It's not GUIRegisterMsg and $WM_LBUTTONSBLCLK that don't work, it's something about how you use them.

[Melba23]

Rat,

In a similar vein, I cannot find where you declare $LongName. You create a GUI using that as the title and have numerous references to it, but you never declare it. When you try running your script, do you not get multiple warnings about undeclared variables?

Or are they all stored in your InstantSupportDefs.au3 include file?

Yep its all in that Defs file... see below:

Rat,

When I run your script (after commenting out a fair bit of code so that it actually runs on my system ) I get the handler to run when I click in the correct place and the TOPMOST flag is definitely removed from the $LongName GUI. So I am at a loss to understand why it does not work for you.

Sorry.

M23

[Rat]

Thanks for your efforts M23,

Could you post your "modified" working code here...it may provide some clues for me?

Cheers,

Rat.

[Melba23]

Rat,

Sorry, already overwritten by another script. I run forum help scripts under a series of "scratch" names and yours has gone to the great recycle bin in the sky.

All I did was comment out the lines which caused errors when I ran the script on my system (such as FileInstall, ShellExecute, IniWrite, RegWrite, etc).

M23

[Rat]

Well thats a bit of a shame...

I'm afraid I have reached the end of the road with this script. I will have to release it to the ChunkVNC fraternity without this final feature and hope that someone else can resolve the problem.

Thanks again for your help.

Cheers,

Rat.

[Melba23]

Rat,

I will try and do better next time!

M23

[Authenticity]

There is always a hope *)

You can be sure that nothing is wrong with either GUIRegisterMsg or $WM_LBUTTONDBLCLK. I think that somehow, some controls take the entire GUI area so you won't be notified about double click events through the GUI event handlers. Check to see where.

Edited June 9, 2010 by Authenticity

Hi Authenticity,

Well if the parameter $ShowId = False then the clickable logo image will be the only control on the window... however I have just discovered that if $ShowId = True then double-clicking the (now visible) ID Code displayed below the logo will call the event handler, (and un-pin the window, even though its outside the logo bounding rect?).

This looks a lot like a CLUE but I haven't been able to progress much past this point

I have included the latest versions of both the Definitions script file and the Window script file below for anybody will to take on the challenge

Cheers,

Rat.

I've also noticed that the LParam message cracking for the mouse X and Y coordinates is probably incorrect. I believe it should be:

;   $Y = BitShift($LParam, 16)
;   $X = BitAND($LParam, 0xFFFF)

However this then prevents the double-clicking on the ID Code from working, as described previously... another CLUE no doubt.

In fact it indicates that the logo image will not accept double-click messages, since the (incorrectly) calculated X-Y coordinates fortuitously happened to fall within the Logo bounding Rect thus triggering the code to un-pin the window.

This image was added with the following command:

$LogoPic = GUICtrlCreatePic($TempPath & '\logo.jpg', $LogoLeft, $LogoTop, $LogoWidth, $LogoHeight) ; , BitOR($SS_NOTIFY,$WS_GROUP,$WS_CLIPSIBLINGS))

So perhaps something about that call to "GUICtrlCreatePic()" is causing the problem?

Rat,

I may have the answer!

Firstly, you are reading the coordinates from your doLButtonDblClk handler the wrong way round! Reversing them gives valid returns for doubleclicks both in and outside the logo area - as long as the logo is absent. This might well explain the apparently random nature of the handler firing!

However, if you create the logo you lose all the double clicks within the logo area - GUICtrlSetOnEvent obviously eats the second click as it fires on the first. So as your unpin code is only fired when the double click is within the logo area it never runs.

The problem is solved if you disable the pic control, but then you do not get the doLogoClicked function to fire.

How about reversing the logic of the doLButtonDblClk code and unpinning the GUI when you click outside of the logo area? Then you could simplify the handler enormously (any doubleclick would fire the code as it woudl not refgister if on the logo) and you could still have the doLogoClickedfunction activated.

Over to you!

Edit:

I see we cross posted and you have realised the first part!

[Rat]

Hi M23,

I had actually considered the possibility that the single click event may "mask" the double-click event so I had disabled the single-click event altogether during testing, (ie. $AllowLogoClick = False).

In hindsight however I suspect that even if I did manage to get the double-click event handling working successfully, then this may still interfere with single-clicking. This inspired me to attempt the following work-around where I used a timer in the single-click event to simulate double-click handling, (see code snippet below). Unfortunately, this didn't work... Windows still knows that a double-click has occurred and will not call the single-click event. I could possibly do this by setting a handler for the mouse down/up windows messages, but I am starting to consider code readability issues here, (since this is an open-source project), and may simply set a Hot Key instead.

Please feel free to investigate the whole double-clicking on images issue further, i suspect it could do with some closer inspection by the AutoIt community.

In many cases the logo occupies the entire client area of the window so this isn't an option.

ps. I also didn't want end-users to disable pinning with a single-click because in my experience the first thing that users tend to do is click the image, (its true... everyone does it!)

Cheers,

Rat.

Hi Melba23,

Thanks for the code... I'm sorry I didn't reply earlier, I was called away for a couple of weeks and didn't notice the reply until today.

Before I left I did a quick fix using a Hot Key combination approach instead, and that seemed to cause no complaints. I have stored your code snippet away for future reference though

Cheers,

Rat.
