EA_OnPostOpenDiagram not called,when Diagram open

[2ben7]

Hi,

this event works if Diagram is not still open. But how to i recognize a switching between different still opened diagrams ? I can`t find a suitable event.

thx

EA_OnPostOpenDiagram will fire only when the diagram is opened.

If you are looking for an event that fires when switching between diagrams that were previously opened (lik eg clicking tabs) => there isn't one.

But maybe this helps: clicking on a diagram will fire EA_OnContextItemChanged - provided that diagram didn't already have the focus.

that would make it.... difficult.
Not suggest that there is nothing like this existing.

I have another idea: is it at least possible to get an event
of all opened diagrams, so i would iterate through all diagrams, if i
switch through still opened diagrams ?

[Paulus]

OK if your diagram already contains at least one element that has compartments eg a class, document artifact, etc in fact most elements in EA) then you can use EA_QueryAvailableCompartments: this will get fired for each element on your diagram.

But *beware* this event is fired *a lot* especially when you drag eg a dialog across the diagram  (it seems like every WM_PAINT causes it to fire).

So make sure that whatever you do takes as little time as possible  (maybe implement a timer that triggers another event, and is reset on every call to EA_QueryAvailableCompartments)

hope this helps,

regards,

Paulus

i tried the event.
When i start EA 9.3 the event is called only once until the project is loaded.

But if i open several new not opened diagrams -> event not called
if i switch between the opened diagrams -> also not called

[Paulus]

... that's odd: I create 2 new class diagrams and from the toolbar drop a new Class on each diagram.

Just to be sure i close both diagrams and reopen them. If i switch between both diagrams using tabs the event EA_QueryAvailableCompartments fires.

For an example of how EA_QueryAvailableCompartments can be used, see:

Regarding your original question about an event for switching between diagram tabs, there is nothing at this time, but I believe there might be a new broadcast event being added soon in EA 10 that will be of help.  Once EA 10 is out, check the release notes and help documentation for something like "EA_OnTabChanged".  Hopefully should be in there.

No schedule for when EA 10 will be available as yet.

HTH.

yeah, but it was not called on switching.
Her is my usage:

public void EA_QueryAvailableCompartments(Repository repository)
{
      // should be called on still opened (Diagram/Subdiagram) switch      
}

[Paulus]

I notice that you've declared the method as void (ie a Sub) whereas the Sparx help defines it should return a Variant (and the example is returning a String).

If EA is looking for a function EA_QueryAvailableCompartments returning a Variant/String it won't find it so change your code to (i hope i got the syntax right  ):

Code: [Select]

public String EA_QueryAvailableCompartments(Repository repository)
{
     return "";      
}
