@URL=EFS parameters

[balligil]

hi all,

is it possible to use arguments/parameters when calling a function from drawtextrelative? I have tried
drawTextPixel(5,20, showtxt+"@URL=EFS:showhide(a,b)",...)

but it did not work.

Thanks in advance

The solution is to use global variables in your code... For example..

Let's say you wanted to have your BUTTON pass variables "A" and "B". If these variables could be updated is Global Variables. then you would simply have your button code pass to a second function the variables necessary to complete the request..

var A = 0;
var B = 0;

function main() {

     drawTextRelative(0, low(0), " Button " + "@URL=EFS:ButtonClick", Color.black, Color.RGB(0xE0, 0xFF, 0xE0), Text.FRAME | Text.ONTOP | Text.CENTER, "Arial", 8, "ButtonONOFF");

}

function ButtonClick(nButtonPressed) {
  DoSomething(A,B);
}

function DoSomething( Input1, Input2) {
  ...
} 

This way, you can control A and B within your code and then pass these values whenever the specific button is clicked.

You can try this efs, I wrote it to demonstrate the left click, left double click and right button clicks. All it does is call different functions which change variables which are used as titles and position of the buttons. You may have to hide the snapshot window (right click it) to see the first button when you run the efs.

var flg = Text.RELATIVETOLEFT|Text.RELATIVETOTOP| Text.FRAME | Text.ONTOP;
var xx = 480;
var yy = 0;
var nButtonTitle = "Click me!!";
var backcolor = Color.red;
var forcolor = Color.white

function preMain(){
    setPriceStudy(true); 
  setStudyTitle("Button Test"); 
}// end preMain
function main() {
  var BarState = getBarState();
  var nIndex = getCurrentBarIndex();    //debugPrintln("nIndex = " +nIndex); 

    //----------------------------------------------------------------------------------------     
    if (nIndex < -60){return;} // minimizes load time
    if (BarState == BARSTATE_NEWBAR) {     
        barcount +=1;//debugPrintln("barcount = " +barcount);
        getButtons(); 
    }
    return;
}

function getButtons(){
    drawTextPixel( xx, yy, nButtonTitle +" @URL=EFS:catchme", forcolor, backcolor, flg,"Comic Sans MS", 20, -5);
}

function catchme( nButtonPressed ){//should force to manual also
    if ( getButtonPressed( nButtonPressed ) == 1 ) {
        debugPrintln("BUTTON_LEFT            - Left Button Clicked");
        xx = 480;
        yy = 40;
        nButtonTitle = "Click me with the right button!!";
        backcolor = Color.red;
        forcolor = Color.white;
    }
    if ( getButtonPressed( nButtonPressed ) == 2 ) {
        debugPrintln("BUTTON_RIGHT        - Right Button Clicked");
        xx = 600;
        yy = 100;
        nButtonTitle = "Left Double-Click me!!";
        backcolor = Color.white;
        forcolor = Color.black;
    }
    if ( getButtonPressed( nButtonPressed ) == 3 ) {
        debugPrintln("BUTTON_LEFTDBLCLK        - Left Button Double-Clicked");
        xx = 170;
        yy = 50;
        nButtonTitle = "Click me with the left button!!";
        backcolor = Color.yellow;
        forcolor = Color.blue;
    }
    if ( getButtonPressed( nButtonPressed ) == 0 ) {
        debugPrintln("BUTTON_UNKNOWN            - Some Other Button Click");
        xx = 200;
        yy = 50;
        nButtonTitle = "Click me with the right button!!";
        backcolor = Color.yellow;
        forcolor = Color.blue;
    }
    getButtons(); 
    return;
}

//BUTTON_RIGHT        - Right Button Clicked
//BUTTON_LEFT            - Left Button Clicked
//BUTTON_LEFTDBLCLK        - Left Button Double-Clicked
//== function determines if a button was pressed and which on was pressed

function getButtonPressed(nButtonPressed) {
  if(nButtonPressed == BUTTON_LEFT) {return(1);}
  if(nButtonPressed == BUTTON_RIGHT) {return(2);}
  if(nButtonPressed == BUTTON_LEFTDBLCLK) {return(3);}
    else {return(0);}
} 

I hope this helps
