Update _NET_WM_STATE_HIDDEN so the pager on the panel will know
|
||||
whether to display windows as visible or hidden (#105665)
|
||||
|
||||
* src/screen.c (queue_windows_showing): Revert the
|
||||
queue_windows_showing portion of the patch committed on 2004-10-16
|
||||
for #142198--it was an ill-advised optimization.
|
||||
|
||||
* src/window.c (window_showing_on_its_workspace,
|
||||
window_should_be_showing): split the old window_should_be_showing
|
||||
into these two functions, (set_net_wm_state): hidden state is more
|
||||
complex; use window_showing_on_its_workspace to determine the
|
||||
correct value
