Prompting without prompting and direct selection

[StrongBeaver]

Is it possible to check in the background if the user has selected a gradient mesh without prompting the user to select a gradient mesh and only prompt the user to

select a gradient mesh once ? I can't find in the reference guide how to select the direct selection tool ?

var GrdntMesh = mDoc.meshItems.selection = 0;
if (GrdntMesh == 0); {
prompt("Choose a Gradient Mesh Shape");
} else {
};

test 'what is selected'

(function selectionCases() {
  if ( _isTextMode () && _isNoSel () ) {
    alert ( 'mode editing text, nothing is selected' );
  } else if ( _isTextMode () && !_isNoSel () ) {
    alert ( 'mode editing text, something is selected' );
  } else if ( !_isTextMode () && _isNoSel () ) {
    alert ( 'mode editing objects, nothing is selected' );
  } else if ( !_isTextMode () && !_isNoSel () ) {
    alert ( 'mode editing objects, something selected' );
    alert (selection[0]);
  }  
  function _isTextMode () { // mode editing text
    return typeof selection.contents == 'string';
  }  
  function _isNoSel () { // nothing is selected
    return selection.length === 0;
  }
}) ();

What is _isTextMode ?

[o-marat]

when

selection.typename == 'TextRange'; // true

[o-marat]

StrongBeaver , you want to catch the event, at the time when the user has selected something by a Selection Tool?

^New

Or run a script that checks which object is selected at the time of launch?

Using Illustrator ExtendScript perhaps only the second variant.

[StrongBeaver]

o-marat, Are isTextMode & _isNoSel variables ?

[o-marat]

In JavaScript 'function is a value'.

This functions return values of type Boolean (all function that name begins to 'is' must returns boolean value);

Function is not a variable, it's a Object of class Function, but when function completed it becomes the returned value. In this case boolean true or false.

Like that...

[StrongBeaver]

Ah you're calling the functions isTextMode function within the selectionCases function

[StrongBeaver]

How can you verify if a meshItem is selected since it doesn't have a property or method ?

[o-marat]

Maybe I misunderstood something...

for example:

if (selection[0].typename == 'MeshItem') // true or false

Is not that what you want?

[o-marat]

If rewrite the function in your first post:

try {
  duplicateAndMoveMesh(selection[0]);
} catch (e) {
  alert(e); // something errors case
}
function duplicateAndMoveMesh(sel) {
  var msg = 'Select Gradient Mesh object and run script again';
  if (!_isTextMode() && !_isNoSel()) {
    if (sel.typename == 'MeshItem') { // mode editing objects, something selected
      // do something with mesh
      var dpl = sel.duplicate();
      dpl.translate(sel.width + 10, 0, true, true, true, true);
    }
  } else if (_isTextMode() && !_isNoSel()) { // mode editing text, something is selected
    alert(msg);
  } else if (!_isTextMode() && _isNoSel()) { // mode editing objects, nothing is selected
    alert(msg);
  } else if (_isTextMode() && _isNoSel()) { // mode editing text, nothing is selected
    alert(msg);
  }
  function _isTextMode() { // mode editing text
    return typeof selection.contents == 'string';
  }
  function _isNoSel() { // nothing is selected
    return selection.length === 0;
  }
}

Gradient Mesh has a method for selected but can you not assign a Boolean and leave it empty and let a condition or try clause let that be the decision maker whether it's true or false ?

[o-marat]

I think now I'm not understand what is needed and what targets... %\

Perhaps will answer the one who understood.

I need more detailed and simple description of your workflow.

[StrongBeaver]

I can't use the following code;

var GrdntMesh = mDoc.meshItems.selected;

because the method selected requires a Boolean property.  I was wondering if I could leave the above line but let the Boolean property of selected be decided based on a condition / try clause ? If I'm approaching this wrong, sorry

[Silly-V]

it's this?

var GrdntMesh = mDoc.meshItems[0];

GrdntMesh.selected = true; 

[StrongBeaver]

Hrm, Sill that may have worked, and I say may as I don't know whether I can nest a condition into a try clause, I keep getting an error ?

var GrdntMesh = mDoc.meshItems[0];
try {
if (GrdntMesh.selected = 1) {
alert("Gradient Mesh is selected");
} else {
catch{
(GrdntMesh.selected = 0); {
alert("Please Select a Gradient Mesh");
}
  }
};

Wrong syntax

var GrdntMesh = app.activeDocument.meshItems[0];  
//try {  
if (GrdntMesh.selected == true) {  
alert("Gradient Mesh is selected");  
} else {  
//catch{  
if (GrdntMesh.selected == false); {  
alert("Please Select a Gradient Mesh");  
}  
//  }  
};
