Xfce Digest, Vol 191, Issue 7

Tue Oct 22 13:45:12 CEST 2019

I guess it's also critically important to make this distinction. We are going for scenario #2.
Scenario 2: Full CSD, not full HeaderBar (selected for 4.16)

This means

 * replacing XfceTitledDialog with a HeaderBar containing “[icon] [title|subtitle] [window controls]”
 * re-designing those apps that seem like low-hanging fruit (Taskmanager?)
 * using CSD only as simple window decorations for applications
 * this ensures we can gradually make changes and get feedback along the way

This means that for nearly all Xfce components (save for those with the XfceTitledDialog (settings manager)) and the low-hanging fruit, we will be simply using the CSD titlebars. You can get a glimpse of this immediately by running any application with GTK_CSD=1.

Here's Mousepad with the CSD window decorations. (GTK_CSD=1 mousepad)
