TabContainer

Inherits: Container < Control < CanvasItem < Node < Object

A container that creates a tab for each child control, displaying only the active tab’s control.

Description

Arranges child controls into a tabbed view, creating a tab for each one. The active tab’s corresponding control is made visible, while all other child controls are hidden. Ignores non-control children.

Note: The drawing of the clickable tabs is handled by this node; TabBar is not needed.

Property Descriptions

bool all_tabs_in_front = false 🔗

• void set_all_tabs_in_front(value: bool)

int current_tab = -1 🔗

• void set_current_tab(value: int)

• int get_current_tab()

The current tab index. When set, this index’s Control node’s visible property is set to true and all others are set to false.

A value of -1 means that no tab is selected.

bool deselect_enabled = false 🔗

• void set_deselect_enabled(value: bool)

• bool get_deselect_enabled()

If true, all tabs can be deselected so that no tab is selected. Click on the current_tab to deselect it.

• bool get_drag_to_rearrange_enabled()

If true, tabs can be rearranged with mouse drag.

AlignmentMode tab_alignment = 0 🔗

• void set_tab_alignment(value: AlignmentMode)

• AlignmentMode get_tab_alignment()

Sets the position at which tabs will be placed. See AlignmentMode for details.

The focus access mode for the internal TabBar node.

TabPosition tabs_position = 0 🔗

• void set_tabs_position(value: TabPosition)

Theme Property Descriptions

Color drop_mark_color = Color(1, 1, 1, 1) 🔗

int icon_separation = 4 🔗

Space between tab’s name and its icon.

int outline_size = 0 🔗

The size of the tab text outline.

Note: If using a font with FontFile.multichannel_signed_distance_field enabled, its FontFile.msdf_pixel_range must be set to at least twice the value of outline_size for outline rendering to look correct. Otherwise, the outline may appear to be cut off earlier than intended.

int side_margin = 8 🔗

The space at the left or right edges of the tab bar, accordingly with the current tab_alignment.

The margin is ignored with TabBar.ALIGNMENT_RIGHT if the tabs are clipped (see clip_tabs) or a popup has been set (see set_popup). The margin is always ignored with TabBar.ALIGNMENT_CENTER.

Font font 🔗

The font used to draw tab names.

int font_size 🔗

Font size of the tab names.

Texture2D decrement 🔗

Icon for the left arrow button that appears when there are too many tabs to fit in the container width. When the button is disabled (i.e. the first tab is visible), it appears semi-transparent.

Texture2D decrement_highlight 🔗

Icon for the left arrow button that appears when there are too many tabs to fit in the container width. Used when the button is being hovered with the cursor.

Texture2D drop_mark 🔗

Icon shown to indicate where a dragged tab is gonna be dropped (see drag_to_rearrange_enabled).

Texture2D increment 🔗

Icon for the right arrow button that appears when there are too many tabs to fit in the container width. When the button is disabled (i.e. the last tab is visible) it appears semi-transparent.

Texture2D increment_highlight 🔗

Icon for the right arrow button that appears when there are too many tabs to fit in the container width. Used when the button is being hovered with the cursor.

Texture2D menu 🔗

The icon for the menu button (see set_popup).

StyleBox panel 🔗

The style for the background fill.

StyleBox tab_disabled 🔗

The style of disabled tabs.

StyleBox tab_focus 🔗

StyleBox used when the TabBar is focused. The tab_focus StyleBox is displayed over the base StyleBox of the selected tab, so a partially transparent StyleBox should be used to ensure the base StyleBox remains visible. A StyleBox that represents an outline or an underline works well for this purpose. To disable the focus visual effect, assign a StyleBoxEmpty resource. Note that disabling the focus visual effect will harm keyboard/controller navigation usability, so this is not recommended for accessibility reasons.

StyleBox tab_hovered 🔗

The style of the currently hovered tab.

Note: This style will be drawn with the same width as tab_unselected at minimum.

StyleBox tab_selected 🔗

The style of the currently selected tab.

StyleBox tab_unselected 🔗

StyleBox tabbar_background 🔗

The style for the background fill of the TabBar area.
