How do i set default prefix for an element I create?

I think prefix should be set directly in the elment xml - at least for custom elements.
Optimally it should be possible to define different prefixes for different standards and a simple numeric setting in filo preferences select what standard to use: i.e
1) normal electric, relay = K
2) normal electronic, relay = RE
3) RDS 81346 - i think a relay there have three letters...
n) etc, freely defineable

Thanks Nuri, Iĺl try later

And thanks for the list.  Tried their free app but it is limited. And my time and money is too limited to get and study their spec.

Yes "I know enough to screw up things"...
In several fields of technology...   Muuuahhahaha

My 2 cts, I remember which code reading only  commonElementsDir no customElementsDir() (user collection)...

Edit :

// Only Electric labels created so far
//if (current_location.fileName() != "10_electric")
QString qet_labels = "10_electric/qet_labels.xml";
QString filepath = QETApp::commonElementsDir().append(qet_labels);

it only read qet_labels.xml file on common element collection in folder 10_electric/ for the moment !
Need little work for adding this for customElementsDir

Possible patch (not time for) :

// Only Electric labels created so far
//if (current_location.fileName() != "10_electric")
QString qet_labels = "10_electric/qet_labels.xml";
QString filepath = QETApp::commonElementsDir().append(qet_labels);

// For custom collection
#if defined(Q_OS_WIN32)

QString custom_labels = (QDir::homePath() + "/Application Data/qet/elements/custom_labels.xml");
#else
QString custom_labels = (QDir::homePath() + "/.qet/elements/custom_labels.xml");
#endif
QString filepath = QETApp::customElementsDir().append(custom_labels);

Bug 114 fixed.

Greetings.
I would like to know what has been done in this direction? Now I'm doing a great project, and it's very inconvenient to go through the entire library, to put at least a relay winding. It's easier to copy from the previous page, but then auto-numbering does not work. And of course it would be desirable that each element be tagged as it is set in IEC81346-1_Letters

Rename your file to qet_labels.xml and see this litle example.

Hello,

put qet_labels.xml in the root of your elements folder.

Interesting, thanks for your feedback.

Hi there,
I am new to QET, and really liking it in comparison to other electrical drawing packages. However I am struggling a bit with the auto-numbering, and it took me a bit before I realised that it seems that the categories with prefixes have to be sub-categories. Ie you don't seem to be able to assign prefixes to top-level categories / folders. This seems strange, but easy enough to work around.

My example that didn't work (where "circuit_breakers" and "fuses" are folders at root level of elements folder):

<labels>
  <category name="circuit_breakers">
    <prefix>Q</prefix>
  </category>
  <category name="fuses">
    <prefix>F</prefix>
  </category>
  <category name="miscellaneous"></category>
</labels>

and my example that did work (where "circuit_breakers" and "fuses" are sub-folders in a folder "circuit_protection"):

<labels>
  <category name="circuit_protection">
      <category name="circuit_breakers">
        <prefix>Q</prefix>
      </category>
      <category name="fuses">
        <prefix>F</prefix>
      </category>
  </category>
</labels>

What I am now struggling to understand is whether there is a way to keep the sequential numbering for different circuit element types separate (e.g. all fuses as F1, F2, F3, all breakers as Q1, Q2, Q3, rather than ending up with F1, Q2, F3, Q4 etc.). I realise you can create different numbering schemes for each type of circuit element, but this requires you to remember to change the numbering scheme each time you add an element to the folio - which I'm not very good at!

Thanks for any suggestions.

Thanks for quick reply! However I think I'm missing something, as I'd found that file before, but this doesn't seem to keep track of different sequence numbers for different element types. Should it?

Just to make sure I'm being clear, I was hoping to achieve the following:

• Place 1st fuse - label F1

• Place 2nd fuse - label F2

• Place 1st breaker - label Q1

• place 3rd fuse - label F3

• place 2nd breaker - label Q2
  etc.

What actually happens is:

• Place 1st fuse - label F1

• Place 2nd fuse - label F2

• Place 1st breaker - label Q3

• place 3rd fuse - label F4

• place 2nd breaker - label Q5
  etc.
