Change widget parent or duplicate widget. Is is possible? [message #94151]

Hi all!

I am using a modified version of the h5_browser and the widget creation is way too long....
This is why I was thinking in duplicating the widget tree that contains the information of the HDF5 file. It takes a lot of time to create this widget and if it could be duplicated, it would save a lot of time in future calls to the program.
Another option would be to change the widget id of the parent and destroy the entire window keeping apart the widget_tree...

Is this possible? If so, I didn't find a way to do it...
Thanks in advance for your answers, suggestions or comments!

While i don't know the answer to your question, i can imagine that using
the SetData Method might be used as a workaround so you don't have to
recreate the widget more than once.

I hope this helps, Markus

We are talking about widgets and they must be destroyed after the user completes the action. It is like a dilog_pickfile().
The use of the method setdata does not make sense in this case.

The H5_LIST or H5_PARSE functions give you the way to (re)create the H5_browser widget content.

I know and I already store this information to speed up things... The command that takes time and I cannot replace is:
wtree = cw_treestructure(wcol1, value=stree)

This is the command that creates the widget_tree from the HDF5 file info. That is why I need to duplicate this widget or do something similar
Thanks!
