Button to create event on hold and release


Recommended Posts

Hey guys, i'm wanting to make an application so i can control an Arduino based rc tank or car (not sure yet) from my laptop over bluetooth. How can i make it so when i press and hold a button it still triggers an event? as normally they only trigger an event after the release of the button. I want it like this so when i press and hold it sends a forward command and when i release it sends a stop command (not the best way as it could possibly run away if connection is lost but it wont be fast).  I did find another post of someone asking the same question for a camera but they where extremely vague on how they did it. This is more just a proof of concept and if i can get it to work reliably i want to bring in a joystick to control the vehicle and use the buttons for other things. Maybe rc tank battles with a buddy 😃 as i will be integrating a FPV camera and reciever into the application if i can get a webcam connection to be reliable as i have had alot of problems in testing the camera.

ShmoeMo,

A quick and dirty way:

#include <GUIConstantsEx.au3>
#include <MsgBoxConstants.au3>

Global $bPressed = False

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

$cLabel = GUICtrlCreateLabel("Not Pressed", 10, 10, 200, 40)
GUICtrlSetFont($cLabel, 24)
GUICtrlSetBkColor($cLabel, 0xCCFFCC)

$cButton = GUICtrlCreateButton("Push!", 10, 100, 100, 30)

GUISetState()

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $GUI_EVENT_PRIMARYDOWN ; Mouse pressed
            $aCInfo = GUIGetCursorInfo()
            If $aCInfo[4] = $cButton Then ; If over button
                If $bPressed = False Then
                    $bPressed = True
                    GUICtrlSetData($cLabel, "PRESSED!!!")
                    GUICtrlSetBkColor($cLabel, 0xFFCCCC)
                EndIf
            EndIf
        Case $GUI_EVENT_PRIMARYUP ; Mouse released
            $bPressed = False
            GUICtrlSetData($cLabel, "Not Pressed")
            GUICtrlSetBkColor($cLabel, 0xCCFFCC)

    EndSwitch

    ; And if the mouse slips off the button
    If $bPressed Then
        $aCInfo = GUIGetCursorInfo()
        If $aCInfo[4] <> $cButton Then
            $bPressed = False
            GUICtrlSetData($cLabel, "Not Pressed")
            GUICtrlSetBkColor($cLabel, 0xCCFFCC)
        EndIf
    EndIf

WEnd

Oooooo thats getting close. Any way i can do it without having to mouse off the button?

Also just found in my testing as i am modifying and old arduino coms app i wrote if i send a string over serial to a device like an arduino or nodemcu that doesnt have its serial port open it will instantly bsod my pc 🤣🤣🤣🤣🤣🤣🤣

ShmoeMo,

When you reply in future, please use the "Reply to this topic" button at the top of the thread or the "Reply to this topic" editor at the bottom rather than the "Quote" button - I know what I wrote and it just pads the thread unnecessarily. Thanks in advance for your cooperation.

Try this:

#include <GUIConstantsEx.au3>
#include <MsgBoxConstants.au3>

Global $bPressed = False

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

$cLabel = GUICtrlCreateLabel("Not Pressed", 10, 10, 200, 40)
GUICtrlSetFont($cLabel, 24)
GUICtrlSetBkColor($cLabel, 0xCCFFCC)

$cButton = GUICtrlCreateButton("Push!", 10, 100, 100, 30)

GUISetState()

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $GUI_EVENT_PRIMARYDOWN
            $aCInfo = GUIGetCursorInfo()
            If $aCInfo[4] = $cButton Then
                If $bPressed = False Then
                    $bPressed = True
                    GUICtrlSetData($cLabel, "PRESSED!!!")
                    GUICtrlSetBkColor($cLabel, 0xFFCCCC)
                EndIf
            EndIf
        Case $GUI_EVENT_PRIMARYUP, $cButton
            $bPressed = False
            GUICtrlSetData($cLabel, "Not Pressed")
            GUICtrlSetBkColor($cLabel, 0xCCFFCC)

    EndSwitch

WEnd

Hmmm, i cant seem to get it to work inside my main function (Arduino_Controller). If i have a while 1 anywhere inside that function it doesn't seem to execute when called from the previous function (the first) and the script just sits inside my system tray paused but no errors are being listed/logged and i cannot unpause it. And if i have the switch section in without a while 1 i can't use the [4] argument? in the "If $aCInfo[4] = $Forward_but Then" section. If i remove [4] my script runs fine but the button press/release is not detected. Sorry if im a spud 🤣 and the fact my script is pretty messy. I need to clean it up and remove some not needed stuff. I pasted my entire script as its not very big.

Try to make a replicable snippet of your script.  We cannot help you much since we cannot run it.  Remove everything that relates to Arduino, see if you observe the same behavior.

ShmoeMo,

You are mixing OnEvent and MessageLoop modes in that script - never a good idea unless there is a very good reason and you know exactly what you are doing.

Here is modified version of your script which does react as you want:

;#include <CommMG.au3>
#include <ButtonConstants.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <ColorConstants.au3>

Global $CMPort = 1
Global $CmBoBaud = 9600
Global $sportSetError = ''
Global $CmboDataBits = 8
Global $CmBoParity = "none"
Global $CmBoStop = 1
Global $setflow = 2

Global $forward_but, $forward_label

$Form1 = GUICreate("", 200, 120)
GUISetOnEvent($GUI_EVENT_CLOSE, "_ExitFunction")
$combo1 = GUICtrlCreateCombo("Select Com Port", 8, 10, 185, 20)
;~List's All available Com Ports
;GUICtrlSetData(-1, _CommListPorts())
$combo2 = GUICtrlCreateCombo("Select Baud Rate", 8, 30, 185, 20)

There are still some weird effects with some of the labels, but you should know what you want to see and can manage to sort that.
