For horizontal panels, show tab bar instead of title bar #22050

Looks good! |

Nice!! Something odd going on with the drop shadow when undocked :) Think it's not feathered |

And for some reason, opening the Mixer the 2nd time, crashes the app. No other MS4's were open. Screen.Recording.2024-03-26.at.10.48.21.720.mov |

@jessjwilliamson Drop shadow will be back in #22046! (Was a Qt 6 regression.) I can reproduce a crash sometimes, but not reliably. I'm having difficulties finding out what's causing it. @Eism Could you perhaps take a look? I fixed the navigation order of the panels, and temporarily hid the "Customise Mixer" button until it's fully implemented. |

@cbjeukendrup @jessjwilliamson I fixed the crash, please review |
KDDockWidgets requires using two MouseAreas: one for dragging the title bar (which will drag the whole floating window when it's undocked) and one for dragging individual tabs (this will drag the tabs out of the floating window, which gives a strange effect when there is only one tab in the floating window. The design specifies that we want tabs instead of a title bar for horizontal panels even when there is only one tab. In this case, we need to make the tabs visible, but make their MouseArea disabled, and instead use the title bar MouseArea.
Old situation: you tell the docking system a navigation panel for each dock panel, and the docking system will mess with the order of this panel. Problems: if a dock panel contains multiple navigation panels, you need to chain those other panels to the first one. And if the first panel is not really available, as in the case of the mixer toolbar, you can't tell the docking system about it. New situation: you tell the docking system about the navigation section directly, instead of the navigation panel. The docking system will give you a `contentNavigationPanelOrderStart` property back, which you can use to correctly set the order of all navigation panels in your dock panel.
reset toolbarComponent when destroying panel
Turns out to be necessary after rebase

@Eism The crash fix works indeed, and I rebased! But just now I found another regression: when opening the Mixer while another panel is already open, it does not become the active tab. So I'll need to fix that. Not sure if that will be before 4.4 (probably better to delay this, as it might be a bit too risky at this stage) |
And add a proof-of-concept mixer toolbar button (not functional yet).
Somewhat related to #22016 and #11335
