I am trying to do the folowing:

I open one window (%ww) for data input and output including some button controls.

Depending on the user's actions a second window (%ww) opens next to the first one to provide additional means for data input and evaluation.

Now when window #2 is open, the controls of window #1 cannot be operated. That means, the buttons show the depressed status all right when activated by my mouse, but the callback function is not called.

None of the windows use &lw becasue I do not want the prog to carry on while the two windows are open.

I am using clearwin+

Any ideas would be welcome.

If you want the first window to remain active when the second window is open then you must make the second window "modeless" by using %lw in the winio@ declaration of the second window.

See "Closing a window" in the FTN95 help file.

Thanks Paul, did not know that and surely give it a try.

Paul,

sorry for bothering you further but just one more question:

How do I make the second window to wait for input after I used %lw? My prog carries on in processing data that are not available, sleep@ stops the prog completely, not accepting any input. But the prog should wait until input from either window #1 or #2 is available.

That possible ?

Thanks in advance.

If you want to be able to access the first window without closing the second then the main idea is that you do not wait for the data.

1) Use COMMON blocks (say) to hold the common data.
2) Use callback functions on the controls to detect changes in the data.
3) When a change is detected that requires an update, process the data in a callback and (if necessary) use window_update@ to update values that are displayed one of the windows.
