I'm wondering if there is any way to temporarily cancel the listener. There are occasions where the app itself has to make changes to the entities and in such occasions it may not make sense to track these changes. I reckon its this: removeTransactionListener() So, I suppose I suppose I will have to...

Your recomendation has been taken to heart, and the necessary adaptations have been done so my app doesn't implode when Qcad receives an update. Anyone who looks at my code now will probably be induced in error and think I actually know what I'm doing!

Thank you, andrew.

getAffectedObjects() provides a list of entities that have been changed. getPropertyChanges(vl_objIds ) provides a list of changes on that particular entity, the Id of THE CHANGE is provided by: test3 = vl_change_list .getPropertyTypeId(); test4 = test3.getId(); Each type of change has an ID associa...

Is there any list of the modification Id's that we can peruse?
It's kind of annoying to use the debugger to individually test for them =P

Thank you.

Just to hammer it down for those who are searching for a code example: // create a new transaction listener: AutoRefresh = new RTransactionListenerAdapter(); //Considers every alteration appWin.addTransactionListener(AutoRefresh); //Will be called whenever there is a change in objects AutoRefresh.tr...

I'm stumped... so I made 3 tests that went to hell, but i required components of two of them to make it happen!

That's awesome.

Well, now I got it running. Thank you, andrew.

Parsing strings to fetch information is certainly not the recommended way to retrieve any information from entities, document, transactions, etc. These output strings you are using are meant for debugging only and can change significantly in any future update which means your code will break. Thank...

On the same line of thought. I noticed that the getPropertyChanged that I used on the example on my last post did not seem to tell me which color it was changed to, and changed from. Is there any way to receive that information through this process we were discussing? Or does this method do that alr...

So let's see. As a simple test I did: AutoRefresh.transactionUpdated.connect(function(document, vl_changes) { if (isNull(document) || isNull(vl_changes)) { return; } vl_objIds = vl_changes.getAffectedObjects(); //Since vl_objIds gets me the id of the changed entity anyway I use it to get the specifi...

Just wondering if there is any manner of flag in this process that is activated according to the type of change that is made on an entity. For example, RTransactionListenerAdapter indicates that a change occured, and some other listener additionally informs that the change was in the color of the en...

RTransaction::getAffectedObjects returns a list of object IDs as integers ( RObject::Id ) not strings.] Correct once again, andrew. I failed to see the "vl_change_list= vl_objIds.toString();" on my own code. Gonna do some testing, but I suppose this is all I'll need for now. Thank you so very much,...

Thank you, andrew. Btw, I believe it's also relevant to mention that the listener is changed when an entity is added, deleted AND when the points are changed. Example: Existing line from 0:0 to 0;10. Same entity is changed to 10;0 to 0;10. Listener activated. Just is case anybody was wondering. Than...

Entity_to_text(entity); simply takes the Id of the entity and returns it as a string. Since I'll have to compare it with other sources that mostly work as strings. function Entity_to_text(entity){ var Entity_ID; Entity_ID = entity.getId(); Entity_ID = Entity_ID.toString(); return Entity_ID; } vl_obj...

I will continue using transaction then. Thank you. Regarding the second question. Example: entityIds = doc.queryAllVisibleEntities(); for (i = 0; i < entityIds.length; i++) { entity = doc.queryEntity(entityIds[i]); Entity_ID = Entity_to_text(entity); if (Entity_ID == custom_ID){ //Does stuff break; ...

Apologies, you are absolutely correct. And yes, my example with the transaction method works perfectly. I just wanted to limit it only to changes in entities. The example is the same, but with; AutoRefresh = new REntityExportListenerAdapter(); //Considera alterações às entidades appWin.addEntityExpo...
