[SOLVED]text output

lexan

hi everyone. I'm planning to display a question on my image that would come from a script or code...

for example

@var answer;
var question;
switch(operation)
{
case 0:
answer= firstVar + secondVar;
question=firstVar +"+"+ secondVar;
break;@

I need to display the question thingy on the falling objects I'm doing

how would i do that? :D
thanks for the response in advance :D

Chuck Gao

I'm sorry, but you want to use QML ? What's your falling object ?

lexan

yeah im using QML right now.. falling object.. a custom image of a meteor

Chuck Gao

I think that's should not be a problem. Do i understand it right ?
@
....

property string questionText : ""

function xxx() {
var answer;
switch(operation)
{
case 0:
answer = firstVar + secondVar;
questionText = firstVar + "+" + secondVar;
break;
}
}

Image {
.....

Text {
anchors.centerIn: parent // Something like this
text: questionText // So the questionText should be a property
}
}

....
@

lexan

wait Im gonna try that :D

lexan

your code seems helpful but now the image doesn't appear

this is my complete code

@import QtQuick 1.0
import "Logic.js" as Logic

Rectangle{
property string questionText:""

function questions(r){
    var first = Math.floor(Math.random()*11);
    var second = Math.floor(Math.random()*11);
    var operation = Math.floor(Math.random()*4);

    var answer;
    var question;
    switch(operation)
    {
    case 0:
        answer=first+second;
        question=first+"+"+second;
        break;
    case 1:
        answer=first-second;
        question = first + "-" + second;
        break;
    case 2:
        answer=first*second;
        question=first+"*"+second;
        break;
    case 3:
        answer=first/second;
        question=first+"/"+second;
        break;
    }
}

Image{
id:fire
width:90;height:90
smooth: false
visible: false
source: "../../../../../Users/MAJA/Desktop/lahat na/Untitled-1.png"
fillMode: Image.PreserveAspectCrop
Text {
anchors.centerIn: parent
text: questionText
}

ParallelAnimation{
    running: visible

    NumberAnimation{target: fire;property: "width";to:150;duration:1500}
    NumberAnimation{target: fire;property: "height";to:150;duration: 1500}
    NumberAnimation {target:fire;property:"y";from:0 ;to:550;duration:4500}
    NumberAnimation{target: fire;property: "x";from: fire.x* Math.random;duration: 8500}

}

}

}@

so what's the problem here

Chuck Gao

Not trying your code, but something you should make sure:

Your Rectangle width and height and also anchors when necessary

@
Image{
id:fire
width:90;height:90
smooth: false
visible: false // When to set it true
.....

ParallelAnimation{
    running: visible // use fire.visible

....
}

}
@

And a kind advice for you, when you start to write a QML app, have a look at the example and document first :-)

By the way, there are tons of wonderful examples available. Here is a directory for Qt Quick examples:
