TabPane

TabPane is a QTabWidget subclass with a Chrome-style document-tab appearance. The active tab and its page form one continuous surface with no gap or lower border; outward curved shoulders join both lower tab corners to the page. The page body keeps a semantic border on its sides, bottom, and the two exposed parts of its top edge, while the span directly beneath the active tab remains open so no divider cuts through the connection. The strip outside the tabs is transparent, while the connected page surface is deliberately distinct from the window background. Inactive tabs remain quiet with separators and reuse the complete connected-tab silhouette on hover, including its outward lower shoulders. Focus, close-button, disabled, light, and dark states use the shared semantic tokens. Keyboard focus colors the selected tab's outer Chrome silhouette; it never adds a second rounded rectangle around the title text and icon.

from shadcn_qt import TabPane

tabs = TabPane()
tabs.setMovable(True)
tabs.setTabsClosable(True)
tabs.addTab(account_page, "Account")
tabs.addTab(security_page, "Security")
tabs.tabCloseRequested.connect(tabs.removeTab)

The complete inherited QTabWidget API remains available. Enabling native widget styling gives an ordinary QTabWidget the same appearance without changing its existing tabs, signals, movable setting, or closable setting.
