In a Slicer Documentation Wiki I find the term ‘panel chrome’ in relation to re-docking the Welcome window after undocking it, when I am trying to see about expanding the 3D view to fill the screen.
I experimentally clicked the ‘restore’ button in the ‘Welcome To Slicer’ window, and the Welcome window undocks, and “SlicerApp-real” is added to the previously blank title bar of that window, and at that point that window has only a close window ‘X’ control. It surprises me that there isn’t a control present to re-dock the Welcome window. As I google around trying to figure out how to get it re-docked (having only the close window ‘X’ control present), I found at https://www.slicer.org/wiki/Documentation/4.8/SlicerApplication/MainApplicationGUI#Module_Panel the following:
“The panel may be undocked (by left-clicking & dragging the panel chrome or by selecting its undock icon; hidden by selecting the hide (X) icon, or have its display toggled by selecting View->Module Panel. The panel can be re-docked by double-clicking on its chrome.”
What is the ‘panel chrome’?
I’ve never seen that phrase/term before.
I discover that double-clicking on the title bar of the Welcome window will re-dock the window, but why not just retain the ‘restore’ control in the title bar and make it toggle undock/redock?
