widget destroy hangs

[Felix Kater <f kater2 gmx net>]

Hi,

I wrote a tool to edit config files: A widget table with rows of one
label (the variable name) + one entry widget (the value) each.

I've made a load_table() function which destroys and re-loads the widget
table according to the rows of the config file: It does
gtk_widget_destroy() and then ..._pack() the widgets again into the
parent.


load_table() works

a. if it is called from a button's click event

b. if it is called from a thread -- however, only if the table was
never shown before.


I don't understand b. If I once open the top level window with my table
and then let the thread call the same load_table() function it hangs at
gtk_widget_destroy(). Some additional hint: I beleve I took care of
gdk_threads_enter()/leave () everywhere where needed. I use the Tor's
lastest win32 version of gtk and glib.


So, I wonder what's the difference between a widget never shown/once
shown?

What's special about the button click callback?


I'd be glad about any help...
