Context - Ubuntu 18.04.2 LTS Gnome-Shell 3.28.3 Perl 5.26.1 Tk 804.034
Challenge - identifying what event/s is/are issued when a Tk TopLevel window in state 'iconic' is changed to state 'normal'. I have tried binding to Map,Unmap,Configure,Visibility,Expose,ButtonRelease-1 events and while I get the expected events from 'normal' to 'iconic' I do not get any that I can identify in the reverse direction i.e. when I left mouse click on the window's icon(I assigned via $mw->iconphoto(...)) under the Ubuntu Activities bar the window appears but so far I have not found which event/s accompanies said - I'm currently guessing none as the related action is not under Tk orchestration albeit Tk should know such an action occurred and could generate at least a 'Visibility' event.

The problem I am trying to address is a means to re-display a withdrawn 'undecorated' (overrideredirect(1)) window as such windows do not appear to allow being 'iconic' so I have a simple decorated window (initially withdrawn then iconized when 'undecorated' withdrawn) to hold the icon I want which when pressed will in essence raise the 'undecorated' one and quickly withdraw itself - hence the need to bind to whatever event will tell me its now visible!


Any help in direction greatly appreciated!
