GUICtrlSetOnHover UDF!

[MrCreatoR]

Ok, here is what i came up with after 3-4 hours of scripting well ok, it has been long time since then, so... after an year or so of hard scripting/testing!!!

(inspired by this topic)...

GUICtrlSetOnHover UDF...

Syntax:

_GUICtrl_OnHoverRegister(ControlID [, OnHoverFunc [, OnLeaveHoverFunc [, PrimaryDownFunc [, PrimaryUpFunc [, KeepCall_PrDn_Func [, KeepCall_Hover_Func]]]]]])

ControlID can be -1 as in Build-In functions!

Example:

expandcollapse popup

#include "GUICtrlOnHover.au3"

Opt("GUIOnEventMode", 1)

$Btn_Color = 0x7A9DD8
$Hover_Color = 0xFF0000 ;0x7AC5D8

$GUIMain = GUICreate("Letters Hovering Example", 570, 200)
GUISetOnEvent(-3, "Quit")

_CreateLetters_Proc(10, 60, 18, 20)

GUICtrlCreateButton("Close", 30, 120, 100, 30)
GUICtrlSetOnEvent(-1, "Quit")

GUICtrlSetFont(GUICtrlCreateLabel("Letter: ", 35, 170, 200, 20), 9, 800)
$Status_Label = GUICtrlCreateLabel("", 80, 171, 200, 20)
GUICtrlSetColor(-1, 0xFF0000)
GUICtrlSetFont(-1, 8.5, 800)

GUISetState()

While 1
Sleep(100)
WEnd

Func _CreateLetters_Proc($iLeft, $Top, $Width=15, $Height=15)
    Local $iLeft_Begin = $iLeft
    Local $iAsc_Char = 64

    For $i = 0 To 25
        $iLeft_Begin += 20
        $iAsc_Char += 1
        GUICtrlCreateButton(Chr($iAsc_Char), $iLeft_Begin, $Top, $Width, $Height)

        _GUICtrl_OnHoverRegister(-1, "_Hover_Func", "_Leave_Hover_Func")
        GUICtrlSetOnEvent(-1, "_Letter_Events")
        GUICtrlSetBkColor(-1, $Btn_Color)
        GUICtrlSetFont(-1, 6)
    Next
EndFunc

Func _Letter_Events()
    MsgBox(64, "Pressed", "Letter = " & GUICtrlRead(@GUI_CtrlId))
EndFunc

Func _Hover_Func($iCtrlID)
    GUICtrlSetBkColor($iCtrlID, $Hover_Color)
    GUICtrlSetData($Status_Label, GUICtrlRead($iCtrlID))
    Beep(1000, 20)
EndFunc

Func _Leave_Hover_Func($iCtrlID)
    GUICtrlSetBkColor($iCtrlID, $Btn_Color)
    GUICtrlSetData($Status_Label, "")
EndFunc

Func Quit()
Exit
EndFunc

Enjoy!

P.S

Thanks to piccaso for the greatest CallBack tool! Without it, this UDF would never been created!

============================================

History version:

[v2.1] - [04.07.2012]

* Compatibility with ColorPicker.au3 UDF.

* Fixed issue with releasing resources (last unregistered control was still active for hovering).

+ Added function to release all resources: _GUICtrl_OnHoverReleaseResources

+ Added alternative UDF "GUICtrlOnHover_NoCallback.au3", it uses AdlibRegister instead of callback with timer. In some cases callback can cause a memory leak.

The disadvantage is obvious, any blocking function or loop will "freeze" the hovering events.

[v2.0] - [09.06.2010]

* Fixed potential issue with calling $sPrimaryDownFunc function (first call was performed only after recieving WM_COMMAND message, wich is the control event).

* Fixed an issue with blocking the OnHover function - the OnLeaveHover function was not called untill the OnHover function was blocked.

* Fixed(?) (again) an issue when the UDF is not working under 64-bit OS.

* Optimized internal "__GUICtrl_SOH_Call" function to work faster when calling parameters functions.

[v1.9] - [21.05.2010]

* UDF library now compatible with AutoIt 3.3.6.1.

* UDF library renamed to GUICtrlOnHover.au3.

* Changed the main function name to _GUICtrl_OnHoverRegister, For backwards compatibility reasons, other (old) function names are still supported:

-----_GUICtrl_SetOnHover, GUICtrl_SetOnHover, GUICtrlSetOnHover, _GUICtrlSetOnHover

* Fixed(?) issue when the UDF is not working under 64-bit OS.

* Global variables and internal functions renaming (for "cosmetic" reasons only).

* UDF's code is more readable now.

[v1.8] - [28.09.2009]

* Few Global variables now have more unique name.

* Fixed an issue with false calling of function on PrimaryDown event. I.e when the user clicks on other place (not on the hovered control) and drag the cursor to the control, the PrimaryDown function was called.

* Due to (and as a result of) previous issue, the UDF now registering WM_COMMAND and WM_LBUTTONDOWN messages at first UDF call.

[v1.7] - [07.07.2009]

+ Added _GUICtrl_SetHoverOnBackwindow...

----Allows to set the hovering mode:

----------$iSetBackWin = 1 (default) hovering process will proceed even when GUI is not active (in background).

----------$iSetBackWin <> 1 hovering process will NOT proceed when GUI is not active.

[v1.6] - [12.06.2009]

* Now the UDF compatible with scripts (or other udfs) that uses OnAutoItExit function.

------i.e: "OnAutoItExit" function that was *previously* set by user will be called as well.

+ Added new parameter $iKeepCall_Hover_Func. If this parameter = 1,

------then the $sHover_Func function *Will* be called constantly untill the control is no longer been hovered

------(default is 0, do not call the function constantly).

+ Added new arguments to calling function...

------The OnPrimaryDown/Up function now can recieve one more argument:

------------------------$iClickMode - Defines the Click mode (1 - Pressed, 2 - Released)

* Changed return value - function will return 2 when $iCtrlID is redefined (ReSet, already exists in the controls list).

* Fixed incorrect documentation parts.

* Fixed "onclick" handeling. When using multiple GUIs, the active gui was not recognized properly.

* Fixed(?) bug with "dimension range exceeded" when trying to UnSet a Control.

[v1.5]

+ Added AutoIt 3.2.10.0+ support, but 3.2.8.1 or less is dropped (due to lack of native CallBack functions).

+ Added Primary Down and Primary Up support. Helping to handle with the buttons pressing.

+ Added new arguments to calling function...

------The OnHover function now can recieve two more arguments:

------------------$iHoverMode - Defines the hover mode (1 - Hover, 2 - Leaves Hovering)

------------------$hWnd_Hovered - Control Handle where the mouse is moved to (after hovering).

* Almost all code of this UDF was rewritted.

* Now the main function name is _GUICtrl_SetOnHover(),

------but for backwards compatibility reasons, other (old) function names are still supported.

* Fixed bug with hovering controls in other apps.

* Improvements in generaly, the UDF working more stable now.

[v1.?]

* Beta changes, see this thread's previous posts for more details.

[v1.0]

* First release.

Excellent Job, this is a lot like I had in mind... but using Picasso's Callback.au3 was a nice touch!

Edit:

I can see this:

$HOVER_CONTROLS_ARRAY[$Ubound][0] = GUICtrlGetHandle($CtrlID)

Maybe causing issues with Multiple GUI's?

Edit2:

And this will definately collide with anything I write:

Opt("OnExitFunc", "CallBack_Exit")

Thanks SmOke_N!

I can see this:

$HOVER_CONTROLS_ARRAY[$Ubound][0] = GUICtrlGetHandle($CtrlID)

Maybe causing issues with Multiple GUI's?

Yes it can, i thouth about it to, i think adding GUISwitch(WinGetHandle("")) and ControlGetHandel("", "", $CursorInfo[4]) can fix the problem... but then only forground window will handle the hovering...

I realy can't see perfect solution for this one... but if we use properly the child windows...

expandcollapse popup

#include <GUICtrlSetOnHover_UDF.au3>

$Gui = GuiCreate("GUICtrlSetOnHover DEMO (With Child GUI)", 280, 200)

$Button = GUICtrlCreateButton("Show Child", 20, 160)
GUICtrlSetOnHover(-1, "Hover_Func", "Leave_Hover_Func")

GUISetState()

While 1
    $Msg = GUIGetMsg()
    Switch $Msg
        Case -3
            Exit
        Case $Button
            GUISetState(@SW_DISABLE, $Gui)
            $Child_Gui = GUICreate("Child", 150, 100, -1, -1, -1, -1, $Gui)
            $Child_Button = GUICtrlCreateButton("Child Button", 20, 20)
            GUICtrlSetOnHover(-1, "Hover_Func", "Leave_Hover_Func")
            
            GUISetState(@SW_SHOW, $Child_Gui)
            
            While GUIGetMsg() <> -3
            WEnd
            
            GUISetState(@SW_ENABLE, $Gui)
            GUIDelete($Child_Gui)
            GUISwitch($Gui)
    EndSwitch
WEnd

Func Hover_Func($CtrlID)
    Switch $CtrlID
        Case $Button, $Child_Button
            If GUICtrlRead($CtrlID) <> "New Button" Then GUICtrlSetData($CtrlID, "New Button")
    EndSwitch
EndFunc

Func Leave_Hover_Func($CtrlID)
    Switch $CtrlID
        Case $Button, $Child_Button
            If GUICtrlRead($CtrlID) <> "Button" Then GUICtrlSetData($CtrlID, "Button")
    EndSwitch
EndFunc

Everything will be OK - But again, it's not perfect, sometimes we need to handle child window on the same "level" as the parent window...

And this will definately collide with anything I write

I do not know any way to do this without involve the host script - but maybe realy not needed to stop the timer after the script is exit, i think it will stop by itself, since (as far as i know) all the handles are closed before script exits.. maby here is the same? what you think?

[Achilles]

Great work!!!

Now if I only had time to update all my scripts to use this instead of a mouse check...

[Nahuel]

Awesome job!

[Richard Robertson]

Nice. It should be included in the AutoIt installation in my opinion.

[Pascal257]

I actually haven't test this, but if this is working its soo awesome.

I'll definitely use it!

After some bugfixing and errorchecking this UDF should be included into the AutoIt-Package!

greetings,

Pascal

[Toady]

very useful, thank you.

Hi...i think there is a problem if it`s over an image...the leave hover dosn`t work

Example:

$Pic1 = GUICtrlCreatePic("pic.jpg", 95, 0, 285, 75)
$Label = GUICtrlCreateLabel("Label", 186, 48, 13, 17)
GUICtrlSetOnHover($Yes, "Hover_Func", "Leave_Hover_Func")

Correct me if i`m wrong...

BTW it`s awsome:D

Problem going from one control to another

If you have multiple controls next to eachother that have the OnHover UDF it seems to have problems with the Leave_Hover_Func.

Here is an example. If you move onto a button, then move off, everything is fine.

If you move your mouse across all the buttons, the Leave_Hover_Func appears to have a problem.

The $Hover stuff is to prevent flicker, but I commented it out for this example.

expandcollapse popup

#include <GuiConstants.au3>
#include "GuiCtrlSetOnHover_UDF.au3"

Opt ("guioneventmode", 1)
$btn_color = 0x7A9DD8
$over_color = 0x7AC5D8
;$Hover = 0

$GUIMain = GuiCreate("", 500, 200,(@DesktopWidth-500)/2, (@DesktopHeight-200)/2)

Dim $pbAlphaBtn[26]
Dim $hPriceBook[31]
    $pbX = 10
    $pbAsc = 64
    for $i = 0 to UBound($pbAlphaBtn) - 1
        $pbAsc += 1
        $pbX += 15
        $hPriceBook[$i + 1] = GUICtrlCreateButton(Chr($pbAsc), $pbX, 75, 13, 17)
        GUICtrlSetOnHover(-1, "Hover_Func", "Leave_Hover_Func")
        GUICtrlSetBkColor(-1, $btn_color)
        GUICtrlSetFont(-1, 6)
    Next

$Close = GuiCtrlCreateButton("Close", 100, 120, 100, 30)
GUICtrlSetOnEvent($Close, "_End")

GuiSetState()
While 1
    Sleep(10)
WEnd

Func Hover_Func($CtrlID)
;   if $Hover = 0 Then
        GUICtrlSetBkColor($CtrlID, $over_color)
;       $Hover = 1
;   EndIf
EndFunc

Func Leave_Hover_Func($CtrlID)
    GUICtrlSetBkColor($CtrlID, $btn_color)
;   $Hover = 0
EndFunc

Func _End()
    Exit
EndFunc

Problem going from one control to another

I have notice the problems to, but while i fixing the problem with «on hover leave», the flicking problem still a mistory for me... if i use a mark inside UDF, then the issue with the "flicking" is fixed, but then there is the issue with the leave hovering ...

I will try (i already spent hours on trying ) to find suitable solution...

Thanks to all.

I did it!!!!!!!!!

Finaly!

+ Now when two (or more) controls are closely one to eachother, then On_Leave_Hover function is called correctly!

+ Now if the control is placed inside the Tab control, then also when leaving hovering, the function called as it should.

+ Now the hovering process work even if the GUI window is not active!!! Thanks to amel27 for that, he wrote the function _ControlGetHovered(), that i used to indicate the currently hovered control id.

+ No need for "Mark variables" anymore!

First post Updated!!! - Now all examples and the UDF is stored in archive file. The example in the first post is the best presentation of this UDF!

did so, nice remark...

[Achilles]

Great work! I wish I had time to update all my projects to use this!

Very usefull UDF and working perfect.

Great job

Edit : If im use "Opt("MouseCoordMode", 0)" script not work true
