multiple interacting windows

[tca-adam]

Are there any good examples of this people have seen?

I am still a little confused about the best way to handle events (such as boolean states) in the sub VI and passing this data back to the main VI.

I would like to leave the subVI open as a floating window while my main program keeps grabbing data.

If you post your code, we can help you out.

Here is a quick example of what I am trying to do.........  V8.5

or do I have the whole concept wrong here?

any help would be much appreciated.... I have spent days trying to get this to work!

thanks

I meant to point out I would like to be able my control MAIN VI operation by buttons on the secondary window (event driven).

That last message should have read:

I meant to point out that I would like to be able to control my MAIN VI operation by the buttons on the secondary window VI (both VIs are event driven).

eg from the secondary window, turn on fast data scanning which changes the data sample rate in the main VI.

Hello,

the most important thing if you want to manage multiple windows system, is to define what a window is... and what it needs to exist...

It needs :
    - a context : a main program (main vi) that manage system events and dispatch, with one sub panel,
    - a window owner : graphical environement (a class of display manager associated to a diagram empty VI with many subpanels on front),
    - a graphical owner : sub panel (if you want to hide the the window or move it in the main panel)
    - a window : dynamique vi (reentrant to keep a model, if you have one),
    - a way to communicate : message box (and message box listener),
    - an event loop : to handle what is happenning on its front panel,

then you have a complete multiple windows system.

I can manage 64 windows that way... I can't create subpanels during execution time...

If you combine it with dqObjetcs for data transmitions, it can be very powerfull.

Hope it helps you...

Bye
