Also allow invoking session restoration logic when apps are manually launched

Authored by ngraham on Fri, Nov 1, 3:28 PM.



Right now session restoration logic only ever gets invoked when apps are started
automatically after rebooting, because of the check for qApp->isSessionRestored().
This limits the feature to only working for that use case, since qApp->isSessionRestored()
is set by Qt and we can't override it in the app itself to signal that we want the session
restoration behavior for other reasons. As a result, we can't use it to implement the
behavior of restoring the condition of app when it's manually launched, which has been
requested for several of our apps.

This patch removes the check for qApp->isSessionRestored(), which opens the door to
implementing the requested features in our apps.

Test Plan

D11382 now works

Normal session restoration behavior after a reboot is unchanged

Apps with session restoration behavior but without a user-facing option to invoke it
don't restore session at inappropriate times.

This method behaves weirdly and not what I expected from reading this code.

If no-one has explicitly called KConfigGui::sessionConfig it creates a new one using qApp->sessionConfig() regardless of whether we're session restored or not. If we're not sessionRestored it'll effectively leak a bogus config with a broken ID name.

I think to accept the patch we would need to also change

kconfiggui.cpp:42 to be

  • if (!hasSessionConfig()) {

+ if (!hasSessionConfig() && qApp->isSessionRestored()) {

Can I get a review on this?

Please make sure you try with a few apps that aren't just dolphin

Yep, there are no changes in behavior or regressions when testing with Okular, Kate, System Settings and Discover.
