minimize window

[Toshimi Yamaguchi <toshi2 optimum co jp>]

Hello.

please could someone give advices...
I am developped the program on GNOME.
A program assigns a button to an nornmal window.
I want to assign the same operation as the time of clicking
the minimize button on a window to this button.
The event at the time of clicking a minimize button is
investigated, and although he plans to make it reappear,
it does not work.

If a minimize button (is it the thing as which this name is
sufficient?) is clicked, it remains in the panel.
It will be re-displayed if the button on a panel is clicked.
I want to do this.

Although the tried event is hide/unmap/unrealize,
it will all disappear from a panel.
Therefore, it cannot re-display.

Aren't there any good methods?

Thanks,
Toshimi Yamaguchi
