Delete widget after Wt::WScrollArea::takeWidget()

Added by dima s about 13 years ago

Hi,

I need to do some processing prior deletion of widget taken from WScrollArea so I use takeWidget method of WScrollArea. How can I then delete this taken widget to free memory? If I simply use delete statement to free it I get access violation exception.

Regards,

dima

That should work. Maybe take a look at the stack trace when it crashes or try valgrind?

I was deleting it from another thread. I had to obtain UpdateLock to delete it.

True - any time you touch a widget tree from a thread, whether it's to read or write or delete or whatever, you must hold the update lock...
