Subject: [PATCH] shell/app: Handle workspace from startup notifications
|
|
|
9b660f |
|
|
|
9b660f |
Launching applications on a particular workspace works through
|
|
|
9b660f |
launch contexts and startup notifications. While this is no
|
|
|
9b660f |
longer required by a launcher/WM split, in theory this allows
|
|
|
9b660f |
us to reliably identify the correct window to apply startup
|
|
|
9b660f |
properties to.
|
|
|
9b660f |
|
|
|
9b660f |
However in practice we fail more often than not: Missing support in
|
|
|
9b660f |
toolkits, differences between display protocols, D-Bus activation
|
|
|
9b660f |
and single-instance applications all provide their own pitfalls.
|
|
|
9b660f |
|
|
|
9b660f |
So instead, take advantage of the fact that launcher and WM live in
|
|
|
9b660f |
the same process, and go with the unsophisticated approach: Just
|
|
|
9b660f |
remember the last workspace that was requested when launching an
|
|
|
9b660f |
app, then move the next window that is associated with the app to
|
|
|
9b660f |
that workspace.
|
|
|
9b660f |
|
|
|
9b660f |
This will break X11 applications that set an initial workspace, but
|
|
|
9b660f |
that's legacy functionality anyway (given that there's no wayland
|
|
|
9b660f |
protocol for that functionality), and seems a price worth paying
|
|
|
9b660f |
for making launching apps on workspaces more reliable.
