Hello,
I'm trying to replace my application's own sidebar implementation (based
on GtkListBox/GtkStack) with GtkSidebar, to take advantage of the
standard CSS theme[1]. Currently I have a small obstacle to this
migration.
To reduce the startup time, the application delays populating a page
widget in GtkStack until the first time it is displayed, and it
sometimes takes time. So, until the page widget becomes ready, the
application shows a placeholder page with a spinner.
The actual interaction is:
1. a user clicks "Punctuation" tab for the first time
2. the application starts loading Unicode punctuation characters in
a background thread; if it takes long, a placeholder page is shown
3. the "Punctuation" page is shown
So, my question is, is there any easy way to inject the phase 2 into the
page transition of GtkSidebar?
Thanks,
