[Gambas-user] Fw: Shell with wait does not wait till work complettion

[sundar j]

TextLabel.Text = "Copy in progress"

Shell "cp -r <src> <dst>" Wait
TextLabel.Text = "Completed."

I used above code in my application. Shell indicated that all files are being copied one-by-one. But TextLable did not display Copy in progress. I did lot of experiment with the above code. Finaly i got it working by adding time delay just before shell command. Now my code looks like this :-

TextLabel.Text = "Copy in progress"
wait 0.1

Shell "cp -r <src> <dst>" Wait

TextLabel.Text = "Completed."

I really have no clue  why code worked after inserting time delay.

When copying is in progress TextLabel will indicate "Copy in Progress" .&nbsp; Once copying is complete then TextLable will indicate something else. For some reason wait option in shell command does nothing and I am not able to set the text&nbsp; "Copy in Progress" in TextLabel properly. Is it bug or am I missing some code?

What do you mean by "wait option [...] does nothing"? Does the shell give an error?

I assume that you have something like:



TextLabel.Text = "Copy in progress"

Shell "cp -r <src> <dst>" Wait



If I remember correctly, using this construct prevents the GUI from refreshing itself, so you won't

see anything until the command completes and a new event loop is entered?



I think one could help better with more information.
