Hello guys!
First of all, XTab is a very useful and well-designed tool; a definitive must-have! I'm working on a project on which XTab will surely improve a lot the user experience. Even more: its concept is certainly PERFECT to work with the Actor Framework.
I am, however, experiencing some issues when trying to make them both work together. I created some simple example projects to isolate and illustrate the problems. They are basically the same, but the "Close Tab UE" version uses a stopping scheme very similar to the Picture Viewer provided example. The "Stop Msg" version uses the Actor Framework's messaging structure to send "Normal Stops" from caller to callee when a tab is closed, which I consider much more ellegant once the exchange of messages is made easier by the framework.
A basic explanation of the code is:
- A Top Level VI launches Actor 01, which contains the XTab XControl.
- An Add button on Actor 01 triggers the launching of one or more instances of Actor 02.
- When Actor 02 is fully launched (that is, when its Actor Core VI is running), we are able to get the VI's reference in order to embed it on the XTab.
- Actor 02's Actor Core sends a "Create Tab" message ("embed me!") to Actor 01.
- Actor 01 embeds Actor 02 on the XTab.
- User closes a tab; then, Actor 01 gets, with the VI ref returned when a tab is closed, Actor 02's Close Tab User Event ref or Actor 02's Enqueuer ref, previously written on the front panel, so we're able to stop an Actor using it's Actor Core VI ref.
- Actor 01 generates user event or sends Normal Stop msg.
This would be a very flexible and simple way to do it! But it works only ONCE; on the second attempt, it crashes LabVIEW and bugs the project. If the Top Level VI is executed from outside a LabVIEW project, however, it works nice.
Mass Compiling isn't successful - or am I doing it wrong? (log attached)
I appreciate any suggestions, ideas or solutions for helping me to do this.
Thanks in advance!
Rudison.
