@red.green said in How to assign property values temporarily without breaking existing binding in qml?: How do I make sure that the previous binding is kept intact? Assigning a value breaks the binding - if it was not this way QML would be horribly broken ;-) There are a few ways around it, though. First, most obvious one - set the new value on the binding source. So if you have: Text { text: someProperty } Assign your temporary value to someProperty. You can add some code that will manage it's temporary nature there (onPropertyChanged or better in some object that holds the value of that property). Another way is to set up the binding using Binding element, disable it when Cancel is pressed, then enable it again once your temporary situation changes.

@Eeli-K sorry I have read your comment incorrectly :p

Hi, You need to send property like this: var loadwin = component.createObject(root, {someParameter: "Hello!"}) If you want to send property at any time (not only when your object will create) you need use alias property: property alias someParameter: textElement.text Text { id: textElement anchors.centerIn: parent text: "defaultParameter" } or signals. But I think alias property will be best way in your case. Hope this helps!

I solved that just removing the validators, but I don't know why it worked without the validator. Code below: TextField { id: numeroTelefoneTextField anchors.verticalCenter: parent.verticalCenter anchors.right: parent.right width: parent.width * 0.70 height: parent.height * 0.6 placeholderText: qsTr("Seu número") font.bold: true inputMethodHints: Qt.ImhDigitsOnly }

This has been fixed for Qt-5.6.1: https://codereview.qt-project.org/#/c/160147/

@CharlieG AFAIK inputMethodHints is related to the virtual keyboard. Depending upon the flags the correspoding keyboard will be invoked(like for eg. numerical keypad only or the both). Use validator instead. In your case for eg: TextField { validator: RegExpValidator { regExp: /[a-z]+/ //allow only lowercase alphabets } }
