GUI Button Responsiveness Drops After Setting Color or Background Color

[TitaniusPlatinum]

Hi all,

I'm running into a strange issue and wanted to see if anyone else has experienced this or knows what's going on.

I'm working on a GUI with multiple buttons. One of the buttons has no color modifications and can be clicked extremely rapidly (10+ times per second) with no problem.
However, the moment I use GUICtrlSetBkColor() or GUICtrlSetColor() on a button, that button becomes significantly less responsive, I can only click it around 3–4 times per second.

I have searched the forums and i could only find information about delays these functions can have when modifying large amounts of controls Here but this isn't what I'm encountering.

If you review the below script, you will find you can double click the top button easily and click it fast. But the bottom 2 arn't as responsive and quite slow.
 

#include <GUIConstantsEx.au3>

Global $i = 0

GUICreate("Speed Test", 200, 120)

;Top Button - Fast
Local $hButton = GUICtrlCreateButton("I Click Fast :D", 10, 5, 180, 25)
;Middle Button - Slow
Local $button2 = GUICtrlCreateButton("I click slow :(", 10, 40, 180, 25)
GUICtrlSetBkColor($button2, 0xFF0000)
;Buttom Button - Slow
Local $button3 = GUICtrlCreateButton("I click slow :(", 10, 75, 180, 25)
GUICtrlSetColor($button3, 0xFF0000)

GUISetState()

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $hButton, $button2, $button3
            _bang()
    EndSwitch
WEnd

Func _bang()
    ;to see how fast it's clicking
    ConsoleWrite("hit: " & $i & @CRLF)
    $i += 1
EndFunc

Any idea what's causing this and how i can resolve it?

This issue isn't related to what i'm experiencing. 

The slowness also affects labels which havn't been colored at all

Here is an example
 

#include <GUIConstantsEx.au3>

Global $i = 0

GUICreate("Speed Test", 200, 120)

;Top Button - Fast
Local $hButton = GUICtrlCreateButton("I Click Fast :D", 10, 5, 180, 25)
;Middle Button - Slow
Local $button2 = GUICtrlCreateLabel("I click slow :(", 10, 40, 180, 25)

GUISetState()

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $hButton, $button2
            _bang()
    EndSwitch
WEnd

Func _bang()
    ;to see how fast it's clicking
    ConsoleWrite("hit: " & $i & @CRLF)
    $i += 1
EndFunc

Any Ideas? Or is this a bug?

Ok tested this way :

#include <GUIConstantsEx.au3>

Global $hTimer

GUICreate("Speed Test", 200, 120)

;Top Button - Fast
Local $hButton = GUICtrlCreateButton("I Click Fast :D", 10, 5, 180, 25)
;Middle Button - Slow
Local $button2 = GUICtrlCreateLabel("I click slow :(", 10, 40, 180, 25)

GUISetState()

While 1
  Switch GUIGetMsg()
    Case $GUI_EVENT_CLOSE
      Exit
    Case $GUI_EVENT_PRIMARYDOWN
      $hTimer = TimerInit()
    Case $hButton
      _bang(1)
    Case $button2
      _bang(2)
  EndSwitch
WEnd

Func _bang($b)
  ;to see how fast it's clicking
  ConsoleWrite("hit " & $b & " : " & TimerDiff($hTimer) & @CRLF)
EndFunc   ;==>_bang

Hello @TitaniusPlatinum

I had the same concern a few weeks ago, in this post . Here is a part of the comment :

I just discovered why today : clicking quickly twice on a label control doesn't trigger (twice) the corresponding Case in main loop, because it's recognized as a double click on the label control, which should be taken care of with WM_COMMAND as @Melba23 indicates here  . This "annoyance" doesn't occur with button controls.

Melba23's code indicates the way to handle this. May I suggest yöu save his code on your computer. I kept his useful code about a month ago, saving it under a catchy name '"Double-click a label (WM_COMMAND).au3"

Good luck
