The sidebar

The Sidebar (ui/sidebar.py) is the vertical column on the left, EXPANDED_W (256 px) wide. From top to bottom:

SidebarHeader     logo (opens Settings) · clock · hide button
FavouritesGrid    up to 16 favourites, 4 per row
SpaceSection      one SpaceRow per space, then "New space"
TabListView       the active space's cards, pinned first, then "New card"
tools row         downloads, history, bookmarks, passwords · the Archive

The header#

LogoButton draws the JBrowser mark and opens Settings. ClockLabel is a 12-hour clock that re-aligns itself to every minute boundary, so it never lags. Changed in 1.5.0 SidebarHeader.resizeEvent() places the clock by hand at the exact centre of the header (between equal 44 px side areas), so it stays centred whatever the widths of the logo and the hide button.

Favourites#

FavouritesGrid shows the sites in FavouritesService (services/favourites.py) as icon tiles. A favourite works in every space: clicking it focuses the card that was opened from it in the current space (tab.favourite_id), or opens a new one. Tiles can be dragged to reorder.

Spaces#

Each SpaceRow shows the space's icon, colour, name and card count. Click switches space; double-click edits it; right-click opens the space menu. The SpaceSection container is focusable: ↑ / ↓ switch spaces (Ctrl+Shift+E focuses it). While a card is dragged over a row, the row is highlighted as a drop target (an accent outline), set through Sidebar.drop_target_at(global_pos, exclude), which the canvas, the card list and the Gallery all use.

The card list#

TabListView is a QListView over TabListModel, painted by TabDelegate: favicon, title, sleeping and audio state, a close button on hover. Pinned cards come first. The last row is New card, which opens the Lazy Toolbar.

New in 1.5.0 sidebar.new_card_always (on by default) keeps the New card row even in a space with no cards; turned off, an empty space shows no rows. The list rebuilds when the setting changes.

New in 1.5.0 Cards in the list can be dragged. After the pointer moves DRAG_START (6 px):

  • inside the list, a line shows where the card will be inserted (_drop_row), and releasing calls BrowserState.move_tab();
  • over a space row, that space is highlighted and releasing moves the card there.

Ctrl+Click and Shift+Click select several cards, as on the canvas.

Hiding and peeking#

set_collapsed(True) (Ctrl+B, the hide button, or Hide sidebar in its menu) animates the sidebar's width to 0 and stores appearance.sidebar_collapsed. While hidden, MainWindow watches the pointer: resting within PEEK_EDGE (10 px) of the window's left edge for 140 ms calls peek(), which floats the sidebar over the canvas; it tucks itself away when the pointer leaves. The hide button in a peeking sidebar pins it open again.
