[SOLVED] How to disable a property:

venkatatrins

Hi I am defining my own Qml Item in one file (Tile.qml) as like below.

Rectangle {
id : tile
width: 100
height: 100
color : "red"
property alias text : txt.text
property alias bgColor : tile.color
property alias fontColor : txt.color
property alias fontSize : txt.font.pixelSize

MouseArea {
    anchors.fill: parent
    onClicked: {
        console.log(txt.text&#41;;
    }
}

Text {
    id : txt
    anchors.centerIn: parent
}

}

and using this user defined item multiple times in another file like this
Column
{
spacing : 5
Row
{
spacing: 5
Tile { id : obj11; text: "obj11"; bgColor : "red"; fontColor : "Yellow"}
Tile { id : obj12; text : "obj12"; bgColor : "red"; fontColor : "Black"}
Tile { id : obj13; text : "obj13"; bgColor : "red"; fontColor : "Black"}
}

    Row
    {
        spacing: 5
        Tile { id : obj21; text: "obj21"; bgColor : "red"; fontColor : "Yellow"}
        Tile { id : obj22; text : "obj22"; bgColor : "red"; fontColor : "Black"}
        Tile { id : obj23; text : "obj23"; bgColor : "red"; fontColor : "Black"; width : 200}
    }
}

Here I am actually using the tile item multiple places and able to make changes on any property.
But, I want to restrict the Tile width to 100 and height to 100 all the time. For that I want to disable these two properties so that they would not be accessible from outside. At the same time, I want to give control over all other properties.

If I use nested Rectangle to define tile... in that case I supposed to do property alias for all other properties, that would be a over headache to me.

How can I achieve this, any help is highly appreciable.

Hello, please use code tag is much better to read :) I'm not sure but set properties private is not possible in qml. But you can register the change event on this properties and override the value every time.

Hi,

To add to dasRicardo's answer it is not possible for the built-in properties but for user-defined properties you can try "this":http://qt-project.org/doc/qt-4.8/qml-coding-conventions.html#private-properties way.
