Code: Select all

    var document = this.getDocument();           // Reference to current document
    var ids = document.querySelectedEntities();  // Qset with selected id's
    var entity;                                  // Entity in process (EntityPointer)
    
     Skip on no Selection:
    if (ids.length == 0) {
        //
        // .....
        //
        return;
    }

    // Find Type: Text Entity
    for (i=0; i<ids.length; i++) {    // Cycle through selection
        // Get entity from document by id:
        entity = document.queryEntity(ids[i]);
        
        // Skip when no Entity:
        if (isNull(entity)) {
            continue;
        }
        
        // Filter on Text:
        if (isTextEntity(entity)) {
            //
            // .....
            //
        } // End isText 
    } // Loop selection

    //
    // isTextEntity() among others in library.js
    //
    // There is also: doc.queryAllEntities(undone = false, allBlocks = false, RS.EntityText);
    // What returns an id list of all Text entities.

thanks for answer but

Code: Select all

ecma> a = doc.queryEntity(9145)
RTextEntityPointer(0x92d54e30)
ecma>isTextEntity(9145)
false

9145 is "Text" in attribute editor

a.getData() is RTextData and then i can read values from text.

[CVH]

Code: Select all

var a = doc.queryEntity(9145);

Loads variable 'a' with an REntityPointer to the entity in the document by current id = 9145.

Then one check if variable 'a' is a text entity:

Code: Select all

isTextEntity(a);

Hello,
I have some time again, so I'm writing the script.
Of course, I also look at the manuals, I can't change the searched text or highlight it on the drawing.
Is there a special function that restores the drawing?
Thanks.

Code: Select all

var doc = this.getDocument();
var idx = doc.queryAllEntities();
var entity;
var text;

for(var i=0; i<idx.length; i++)
  {
    entity = doc.queryEntity(idx[i]);
    if(isTextEntity(entity))
      {
        text = entity.getData().getText();
        if(text.contains("GA"))
          {
          EAction.handleUserWarning("found " + text);
          entity.getData().setText("only test");
          }
      }
  }

Hi, that is more than one question.

RTextEntity has also the getPlainText() method.
Common is var ids from 'ID selected' or 'more ID's' but it is at your preference.

RTextEntity is a pointer to a clone of the actual entity.
https://qcad.org/doc/qcad/3.0/developer ... 79a957c678

var text is an RTextData.
(I prefer to name that var textData vs 'text' for a string)

You changed whole the RTextData.text to a newer value.

One needs to create a new RTextEntity from this.

Code: Select all

var newTextEntity = new RTextEntity(doc, text);    // With text is an RTextData

And cast it back to the document overwriting the existent entity.

Code: Select all

var di = this.getDocumentInterface();
var op = new RModifyObjectsOperation();
op.addObject(newTextEntity, false, true);    // NOTuseCurrentAttributes, DOforceNew
di.applyOperation(op);

Processed entities are all in selection.
Remember changed text entities in an array with push ...
At the end of your code deselect all and select those listed in the array.

Code: Select all

var alteredList = [];
....
.... // your code
alteredList.push(idx[i]);
....
....
di.deselectAll();
di.deselectEntities(alteredList);

Thanks,
Now i know little more
a small plus to my zero knowledge of JS.

Text was modified but overlaped old text. so i add delete operation on old TextData and
now seems to work. Dirty solution i know but works

if I complete this script, my work will be reduced to a few minutes instead days.
thanks again for the explanation.

Code: Select all

var doc = this.getDocument();
var di = this.getDocumentInterface();
var idx = doc.queryAllEntities();
var entity;
var text;

for(var i=0; i<idx.length; i++)
  {
    entity = doc.queryEntity(idx[i]);
    if(isTextEntity(entity))
      {
        text = entity.getData().getPlainText();
        if(text.contains("GA"))
          {
          entity.setText("Pokus");
          EAction.handleUserWarning("found " + text);
          var newEntity = new RTextEntity(doc, entity.getData());
          var op = new RModifyObjectsOperation();
          op.addObject(newEntity, false, true);
          di.applyOperation(op);
          var de = new RDeleteObjectsOperation();
          de.deleteObject(entity);
          di.applyOperation(de);
          }
      }
  }

Then NOT force new:

Code: Select all

op.addObject(newTextEntity, false, false);    // NOTuseCurrentAttributes, NOTforceNew

My bad (copy-paste issue)

Now you alter the text directly in the RTextEntity.
No need for the getData or to create a new RTextEntity.
That is, if this is all you need to do ...

RModifyObjectsOperation is plural.
One can set this once outside the loop together with di.applyOperation.
This groups operations, is faster and can be undone in one go.

Code: Select all

var doc = this.getDocument();
var di = this.getDocumentInterface();
var idx = doc.queryAllEntities();
var entity;
var text;
var op = new RModifyObjectsOperation();

for(var i=0; i<idx.length; i++) {
    entity = doc.queryEntity(idx[i]);
    if(isTextEntity(entity)) {
        text = entity.getPlainText();
        if(text.contains("GA")) {
            entity.setText("Pokus");
            EAction.handleUserWarning("found " + text);
            op.addObject(entity, false, false);
        }
    }
}
di.applyOperation(op);
