AdwTabOverview is a widget that can display tabs from an AdwTabView in a grid.

AdwTabOverview shows a thumbnail for each tab. By default thumbnails are static for all pages except the selected one. They can be made always live by setting [propertytabPage:live-thumbnail] to TRUE, or refreshed with [methodtabPage.invalidate_thumbnail] or [methodtabView.invalidate_thumbnails] otherwise.

If the pages are too tall or too wide, the thumbnails will be cropped; use [propertytabPage:thumbnail-xalign] and [propertytabPage:thumbnail-yalign] to control which part of the page should be visible in this case.

Pinned tabs are shown as smaller cards without thumbnails above the other tabs. Unlike in [classtabBar], they still have titles, as well as an unpin button.

AdwTabOverview provides search in open tabs. It searches in tab titles and tooltips, as well as [propertytabPage:keyword].

If [propertytabOverview:enable-new-tab] is set to TRUE, a new tab button will be shown. Connect to the signaltabOverview[createTab] signal to use it.

propertytabOverview:secondary-menu

can be used to provide a secondary menu for the overview. Use it to add extra actions, e.g. to open a new window or undo closed tab.

AdwTabOverview is intended to be used as the direct child of the window, with the rest of the window contents set as the [propertytabOverview:child]. The child is expected to contain an [classtabView].

AdwTabOverview shows window buttons by default. They can be disabled by setting [propertytabOverview:show-start-title-buttons] and/or [propertytabOverview:show-start-title-buttons] and/or [propertytabOverview:show-end-title-buttons] to FALSE.

If search and window buttons are disabled, and secondary menu is not set, the header bar will be hidden.

Actions

AdwTabOverview defines the overview.open and overview.close actions for opening and closing itself. They can be convenient when used together with [classtabButton].

CSS nodes

AdwTabOverview has a single CSS node with name taboverview.

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onTabOverviewExtraDragDrop :: (IsTabOverview a, MonadIO m) => a -> ((?self :: a) => TabOverviewExtraDragDropCallback) -> m SignalHandlerId

page: the page matching the tab the content was dropped onto

-> GValue

value: the GValue being dropped

-> IO [DragAction]

Returns: the preferred action for the drop on page

This signal is emitted when the dropped content is preloaded.

In order for data to be preloaded, [propertytabOverview:extra-drag-preload] must be set to TRUE.
