I know many people (like Valuater and marfdaman) have made things for hovering over labels and whatever else... However I was wondering if it would be possible to someway have some sort of GuiCtrlSetOnHover(). Like it automatically performs a function when you hover, pretty much the exact same as GuiCtrlSetOnEvent except with hovering.

It seems inefficient to me to have a script constantly checking the mouse position to see if it's hovering, although it works great for me! However, I was just wondering if this would be at all possible.

[DirtDBaK]

there is a way to do so! Im not sure how but my buddy did it with the guigetcursorinfo()



But what is impoarant is this part

 $mouse=GUIGetCursorInfo()
  if $mouse[4]=$CONTROL_ID then
     Msgbox(0,"Your Hovering", "Over the control" )
 Endif
  if $mouse[4]<>$CONTROL_ID then
     Msgbox(0,"Your Hovering", "not Over the control" )
  Endif

This was pulled out of a program my buddy made

                $msg = GUIGetMsg()
                $mouse=GUIGetCursorInfo()
                while @error=0
                    if $mouse[4]=$PU then GUICtrlSetimage( $PU, "PU2.BMP")
                    if $mouse[4]<>$PU then GUICtrlSetimage( $PU, "PU.BMP")
                    if $mouse[4]=$SUBMenu[0] then GUICtrlSetimage( $SUBMenu[0], "PU2.BMP")
                    if $mouse[4]=$SUBMenu[1] then GUICtrlSetimage( $SUBMenu[1], "PU2.BMP")
                    if $mouse[4]=$SUBMenu[2] then GUICtrlSetimage( $SUBMenu[2], "PU2.BMP")
                    if $mouse[4]=$SUBMenu[3] then GUICtrlSetimage( $SUBMenu[3], "PU2.BMP")
                    if $mouse[4]<>$SUBMenu[0] then GUICtrlSetimage( $SUBMenu[0], "PU.BMP")
                    if $mouse[4]<>$SUBMenu[1] then GUICtrlSetimage( $SUBMenu[1], "PU.BMP")
                    if $mouse[4]<>$SUBMenu[2] then GUICtrlSetimage( $SUBMenu[2], "PU.BMP")
                    if $mouse[4]<>$SUBMenu[3] then GUICtrlSetimage( $SUBMenu[3], "PU.BMP")
                    exitloop
                wend

What it did was it changed the picture if you were hovering over the control

I haven't checked in some time, but I believe there is a WM_MOUSEHOVER ... if that is true then you could use GUIRegisterMsg() and some custom mousegetpos/childgetwinfrompoint function. Would be interesting to see what you turn out.

There is, and you could, but it's questionable if it's really worth it in the end... when GUIGetCursorInfo does it all for you.
You need to call TrackMouseEvent each time that message pops. If you want to be more efficient, you need to subclass the control to catch its WM_MOUSEHOVER messages, because trying to work out control hover using WM_MOUSEHOVER of the main window isn't all that different from polling GUIGetCursorInfo in your main loop.
I did some WM_MOUSELEAVE tracking in one of my AutoIt apps, to get when the mouse enters/leaves window, and it worked, but then I ditched whole concept for the sake of simplicity.

[therks]

There is, but it looks a little more complicated than that...

The TrackMouseEvent function posts messages when the mouse pointer leaves a window or hovers over a window for a specified amount of time.
...
The mouse pointer is considered to be hovering when it stays within a specified rectangle for a specified period of time. Call SystemParametersInfo. and use the values SPI_GETMOUSEHOVERWIDTH, SPI_GETMOUSEHOVERHEIGHT, and SPI_GETMOUSEHOVERTIME to retrieve the size of the rectangle and the time.

So I'm not sure this is exactly what he's looking for.

It would be WM_MOUSEMOVE...

And customizing "per" gui would be no problem using what I stated... the issue is making it a CallBack (now possible thanks to piccaso I believe) and being able to globally store all the options.

Personally, I wouldn't look forward to writing it to be universal... but it might be up your alley with what you were doing just recently http://www.autoitscript.com/forum/index.ph...c=53390&hl= ... I would think using Call() ... a few globals ... and a callback and you could make it universal with what I suggested...

*** Again, these are just thoughts, I haven't actually sat down to test any of it, but I'm fairly confident I could make it work with RegisterMsg() + a function to work on the WM_MOUSEMOVE with just my own GUI and knowing what was going to be called and what needed changing when called (<< That last part is where I stopped thinking )

[Achilles]

@DBack: That is what I use currently. I was hoping for something that didn't require constant checking.

@The rest: What Smoke_N said sounds like a good option. Like the GuiRegisterMsg()... However, I would have NO idea whatsoever how to do this and I don't have time to learn

If anybody has time and gets it to work it would be sweet!

I use hovering extensively in my color pickin chooser. Check the source.

Once you get your head around the simple fact that Control ID's are just numbers (something the manual doesn't really nail - the GUIGetCursorInfo() page would be good), it's all quite easy to implement. Here's the main loop, whith a whole lotta hovering going on..

AutoIt        expandcollapse  popup

    ; main loop..
    ;
    while not $do_quit
    
        if $do_func <> "" then
            Call($do_func)
        endif

        sleep(75)
        local $mouse_info = GUIGetCursorInfo() ; help file page for this command needs a decent hover example!
        ; in fact, *any* decent examples would be good.

        if $mouse_info = 0 then
            $left_window = true
            cpc_UnSetHotKeys()
        else
            cpc_SetHotKeys()
            if $super_mag and $left_window = true then ; back inside the gui
                cpc_SwitchOffSuperMag()
            endif
            $left_window = false
        endif

        if not IsArray($mouse_info) then continueloop ; outside gui
        local $MousePos = MouseGetPos()
        if not IsArray($MousePos) then continueloop

        ; inside picker, grad, or mag (or dragable info label)..
        if $mouse_info[4] = $pic_color_picker or $mouse_info[4] >= $info_dummy then 
            if $mouse_info[4] = $info_dummy or $mouse_info[4] = $label_colorwell then ; it's trivial to check which control you are hovering over
                GUISetCursor(9, 1, $gui_color)  ; feel free to use something like this for the GUIGetCursorInfo() manual page.
                continueloop                    ; no credit required! ;o)
            endif
            
            GUISetCursor(3, 1, $gui_color) ; "+"
            $cpc_live_color = StringRight(Hex(PixelGetColor($MousePos[0],$MousePos[1])), 6)
            cpc_UpdateLiveColorBox()

            ; hold down left mouse button for live effects..
            if $live_luminance = $GUI_CHECKED or ce_IsPressed(01) then cpc_UpdateLumGrad($cpc_live_color)
            if $live_mag = $GUI_CHECKED or ce_IsPressed(01) then cpc_UpdateMag()

            if $live_hex = $GUI_CHECKED then 
                if ce_IsPressed(10) then 
                    ToolTip(ConvertColorValue($cpc_live_color, $cpc_output_mode, $add_prefix), $MousePos[0]+2, $MousePos[1]+2)
                else
                    ToolTip($cpc_live_color, $MousePos[0]+2, $MousePos[1]+2)
                endif
            endif
            $color_set = 1

        elseif $super_mag then 

            cpc_UpdateMag()
            GUISetCursor(3, 1, $gui_color)

        else ; outside picker areas or window..

            GUISetCursor()
            ToolTip ("")
            if $color_set = 1 then
                if $hold_live_color = $GUI_UNCHECKED then 
                    GUICtrlSetBkColor($label_live_color, "0x" & $cpc_my_color)
                    if $live_luminance = $GUI_CHECKED then cpc_UpdateLumGrad($cpc_my_color)
                endif
                $color_set = 0
            endif
        endif
    wend

I am really looking for a GuiCtrlSetOnHover also.

I have been using Xskin to do this but I have encountered a Major flaw with Xskin and all other hover scripts I have found.

If you have a combo box dropped down and displaying over a button and you select an item that is imediatly over the button, the button gets clicked.

It should be as simple as copying the GuiCtrlSetOnEvent code and just make a function that looks for a Mouseover command instead of a click.

Ok, i think i got it (thanks to SmOke_N for the ideas from his posts)...

Here is the standard method (Not work with Labels, inputs/edits and maybe more controls):

AutoIt        expandcollapse  popup

;NOT WORK WITH LABEL, INPUT, OR EDIT CONTROL!

#include <GuiConstants.au3>

Global Const $WM_NOTIFY = 0x004E

GuiCreate("Test")
GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY")

$Button = GUICtrlCreateButton("Button", 20, 40, 70, 20)
GUICtrlSetOnHover($Button, "My_Hover_Func")

$CheckBox = GUICtrlCreateCheckbox("CheckBox", 20, 80, 70, 20)
GUICtrlSetOnHover($CheckBox, "My_Hover_Func")

GUISetState()

While 1
    $Msg = GUIGetMsg()
    Switch $Msg
        Case -3
            Exit
    EndSwitch
WEnd

Func WM_NOTIFY($hWndGUI, $MsgID, $WParam, $LParam)
    If UBound($HOVER_CONTROLS_ARRAY)-1 < 1 Then Return $GUI_RUNDEFMSG
    
    Local $CursorInfo = GUIGetCursorInfo($hWndGUI)
    If $CursorInfo[4] = 0 Then
        Printf("No Hovered Controls")
        Return $GUI_RUNDEFMSG
    EndIf
    
    For $i = 1 To $HOVER_CONTROLS_ARRAY[0][0]
        If $HOVER_CONTROLS_ARRAY[$i][0] = GUICtrlGetHandle($CursorInfo[4]) Then
            Call($HOVER_CONTROLS_ARRAY[$i][1], $CursorInfo[4])
            ExitLoop
        EndIf
    Next
    Return $GUI_RUNDEFMSG
EndFunc

Func GUICtrlSetOnHover($CtrlID, $FuncName)
    Local $Ubound = UBound($HOVER_CONTROLS_ARRAY)
    ReDim $HOVER_CONTROLS_ARRAY[$Ubound+1][2]
    $HOVER_CONTROLS_ARRAY[$Ubound][0] = GUICtrlGetHandle($CtrlID)
    $HOVER_CONTROLS_ARRAY[$Ubound][1] = $FuncName
    $HOVER_CONTROLS_ARRAY[0][0] = $Ubound
EndFunc

Func My_Hover_Func($CtrlID)
    Printf("Control " & $CtrlID & " [Data: " & GUICtrlRead($CtrlID, 1) & "] Is Now Hovered")

Check this out - I made an UDF from it!

THIS IS ALREADY BUILT-IN TO AUTOIT!

local $MousePos = MouseGetPos()
if $mouse_info[4] = $MyControl then
    ; do something
endif

I don't have the problem with activating controls under drop-downs, either.
Why all the complexity? Am I missing something?

What you use requires the code to be constantly checking to see if something is hovered. The new was that MsCreator put together notifies you when you hover over something and immediately does a function.

For example... would you rather check every second to see if the time is 5:30 by looking at your watch or just set an alarms for 5:30?

[corz]

I don't follow the analogy; *I* don't need to do anything! But surely *some* code needs to be constantly checking for the hover, and it's compact trivial to achieve inside any main loop. I just don't see the need to wrap this inside anything.

Though better examples in the manual would be good.
