DelayButton reset after activation

Mark81

I want to use a DelayButton to avoid accidental clicks, but I'm not interested in the checkable feature. Hence, once activated I want to un-check it to be ready to a new press.

I tried to do this, but it does't work:

DelayButton {
    text: "RESET"                
    onActivated: { 
        // do something
        checked = false 
    }
}

also set the checkable property to false in the definition doesn't work. What is the right way to do this?

Hi @Mark81
I tried on Windows 10 (x64) and Qt versions 5.10.0, 5.10.1 and 5.11.0 and setting checked = false works?

After activation and releasing the button, the state is reset and I can press it again until it triggers.

import QtQuick 2.10
import QtQuick.Window 2.3
import QtQuick.Extras 1.4

//ApplicationWindow {
Window {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")

    DelayButton {
        delay: 1000
        text: "RESET"

        onActivated: {
            console.debug("Activated!")
            checked = false
        }
    }
}

Found the problem. I'm using the DelayButton from QtQuick.Controls instead of the one in QtQuick.Extras because I like the rectangular shape rather than the circular one and I'm using other object from Controls. But the behavior is different, though.

I find confusing to have the same object in two different imports... I don't know if I can live with the "extras" one. Please, would you try the very same code with:

import QtQuick.Controls 2.2

to try if it doesn't work as expected now?

I didn't see your message because you did not directly reply to mine (or I did not get the notification), hence the delay.
This delay did hence not come from the button^^.

I tried with import QtQuick.Controls 2.2 and then indeed I get the same behavior as you are experiencing.

However, I achieved the reset by simply using:

        onActivated: {
            console.debug("Activated!")
            progress = 0.0
        }

Although the online Qt doc says that the progress property is read-only, it is not!
http://doc.qt.io/qt-5/qml-qtquick-controls2-delaybutton.html

I found a hint for this by looking at the source code:
https://code.woboq.org/qt5/qtquickcontrols2/src/quicktemplates2/qquickdelaybutton.cpp.html#_ZN17QQuickDelayButton11setProgressEd

Since it has a setProgress method I reckoned that it also must be exposed to QML which it apparently is. I did not look at the header file for closure about this, but since it works...
