Add text width from previous text line to text position

[acafilipovic]

Hi,

I don't know how to use value of the text width from previous line and add it to a current text line position.

Function createText() is creating a text and function txtPreWidth() should return the text width from previous line.

When I alert the txtPreWidth(), it's giving me the right value, but when I put it in createText() function I'm getting undefined.

I think it should work like this but it's not.

Maybe I should store the text width in an object and then I don't need to create another function.

This is the script:

 function myScript(thisObj){
     function myScript_buildUI(thisObj){
         var myPanel = (thisObj instanceof Panel) ? thisObj : new Window("palette", undefined, {resizeable:true});
//================================================================================================================
var textBox = myPanel.add("edittext", undefined, "My text goes here!", {multiline:true});  
    textBox.minimumSize = [300,100];
var myButton = myPanel.add("button",undefined,"Create Markers");
myButton.onClick = createMain;
//================================================================================================================
function createMain(){
var textBoxContents = textBox.text;
var lines = textBoxContents.split(/\n|\r/);
createText(lines,0);
}
//==================================================================
function txtPreWidth(line){ // This function should return value of text Width from previous text line.
    for (var i = 0; i < line.length; i++) {
        var textlayer = app.project.activeItem.layers.addText(line);
        var textlayer_TextProp = textlayer.property("ADBE Text Properties").property("ADBE Text Document");
        var textlayer_TextDocument = textlayer_TextProp.value;
            textlayer_TextDocument.fontSize = 100;
            textlayer_TextProp.setValue(textlayer_TextDocument);
  var txtWidth = (textlayer.sourceRectAtTime(0,false).width);
    textlayer.remove()
    return txtWidth;
    }
}
//================================================================
function createText(line, yPos){
 var y = yPos;
    for (var i = 0; i < line.length; i++) {
        var textlayer = app.project.activeItem.layers.addText(line);
        var textlayer_TextProp = textlayer.property("ADBE Text Properties").property("ADBE Text Document");
        var textlayer_TextDocument = textlayer_TextProp.value;
            textlayer_TextDocument.fontSize = 100;
            textlayer_TextProp.setValue(textlayer_TextDocument);
        textlayer.moveToEnd();
  var txtWidth = (textlayer.sourceRectAtTime(0,false).width); // Text width from current line.
  y += 30 + txtWidth; // The script should use the text width from previes line and add it to it. That value is in txtWdith();
        textlayer.property("ADBE Transform Group").property("ADBE Position").setValue([200,y,0]); 
    }
}
//================================================================================================================
        myPanel.layout.layout(true);
        myPanel.minimumSize = myPanel.size;

        myPanel.layout.resize();
        myPanel.onResizing = myPanel.onResize = function(){this.layout.resize()};


         return myPanel;
         }
        var myScriptPal = myScript_buildUI (thisObj);

        if((myScriptPal != null) && (myScriptPal instanceof Window)){
            myScriptPal.center();
            myScriptPal.show();
        }
}
myScript(this);

Hi

        function txtPreWidth(line) { // This function should return value of text Width from previous text line. 
            for (var i = 0; i < line.length; i++) {
                var textlayer = app.project.activeItem.layers.addText(line);
                var textlayer_TextProp = textlayer.property("ADBE Text Properties").property("ADBE Text Document");
                var textlayer_TextDocument = textlayer_TextProp.value;
                textlayer_TextDocument.fontSize = 100;
                textlayer_TextProp.setValue(textlayer_TextDocument);
                var txtWidth = (textlayer.sourceRectAtTime(0, false).width);
                textlayer.remove()
                return txtWidth;
            }
        }

this code return txtWidth when i=0 only

if you want to return about all lines,

        function txtPreWidth(line) { // This function should return value of text Width from previous text line.  
            var txtWidths = [];
            for (var i = 0; i < line.length; i++) {
                var textlayer = app.project.activeItem.layers.addText(line);
                var textlayer_TextProp = textlayer.property("ADBE Text Properties").property("ADBE Text Document");
                var textlayer_TextDocument = textlayer_TextProp.value;
                textlayer_TextDocument.fontSize = 100;
                textlayer_TextProp.setValue(textlayer_TextDocument);
                var txtWidth = (textlayer.sourceRectAtTime(0, false).width);
                textlayer.remove()
                txtWidths.push(txtWidth);
            }
            return txtWidths;     //Array
        }

or want to return previous line only,

        function txtPreWidth(line) { // This function should return value of text Width from previous text line.  
            for (var i = 0; i < line.length; i++) {
                var textlayer = app.project.activeItem.layers.addText(line);
                var textlayer_TextProp = textlayer.property("ADBE Text Properties").property("ADBE Text Document");
                var textlayer_TextDocument = textlayer_TextProp.value;
                textlayer_TextDocument.fontSize = 100;
                textlayer_TextProp.setValue(textlayer_TextDocument);
                var txtWidth = (textlayer.sourceRectAtTime(0, false).width);
                textlayer.remove()
                if(_______){     //is previous line check
                    return txtWidth;
                }
            }
            return 0;
        }

Sorry my poor English...

Thank you for the fast reply takeyamaatsushi,

I need previous line only, to use it in createText function.

When I put "alert(txtPreWidth(line));" in createText function I don't get any value, it just create an empty text layer.

Is it possible to use if statement in the createText function to get the previous line value, or I have to create seperate function.

I'm totaly confused, I tried your third function but I don't know what tu put in "if(_______){     //is previous line check".

Can you please help me?

Thanks

My bad, I should use line, instead of line, that's why I was getting an empty array.

Thank you takeyamaatsushi.
