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.

Enumerations
enum TabPosition: 🔗
TabPosition POSITION_TOP = 0
Places the tab bar at the top.
TabPosition POSITION_BOTTOM = 1
Places the tab bar at the bottom. The tab bar's StyleBox will be flipped vertically.
TabPosition POSITION_MAX = 2
Represents the size of the TabPosition enum.
Property Descriptions
bool all_tabs_in_front = false 🔗
If true, all tabs are drawn in front of the panel. If false, inactive tabs are drawn behind the panel.
If true, tabs overflowing this node's width will be hidden, displaying two navigation buttons instead. Otherwise, this node's minimum size is updated so that all tabs are visible.
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 🔗
If true, all tabs can be deselected so that no tab is selected. Click on the current_tab to deselect it.
Only the tab header will be shown if no tabs are selected.
bool drag_to_rearrange_enabled = false 🔗
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.
FocusMode tab_focus_mode = 2 🔗
The focus access mode for the internal TabBar node.
TabPosition tabs_position = 0 🔗
void set_tabs_position(value: TabPosition)
TabPosition get_tabs_position()
Sets the position of the tab bar. See TabPosition for details.
int tabs_rearrange_group = -1 🔗
TabContainers with the same rearrange group ID will allow dragging the tabs between them. Enable drag with drag_to_rearrange_enabled.
Setting this to -1 will disable rearranging between TabContainers.
If true, tabs are visible. If false, tabs' content and titles are hidden.
If true, child Control nodes that are hidden have their minimum size take into account in the total, instead of only the currently visible one.
Method Descriptions
Control get_current_tab_control() const 🔗
Returns the child Control node located at the active tab index.
Returns the Popup node instance if one has been set already with set_popup.

int get_previous_tab() const 🔗
Returns the previously active tab index.
TabBar get_tab_bar() const 🔗
Returns the TabBar contained in this container.
Warning: This is a required internal node, removing and freeing it or editing its tabs may cause a crash. If you wish to edit the tabs, use the methods provided in TabContainer.

int get_tab_idx_from_control(control: Control) const 🔗
Returns the index of the tab tied to the given control. The control must be a child of the TabContainer.
Variant get_tab_metadata(tab_idx: int) const 🔗
Returns the metadata value set to the tab at index tab_idx using set_tab_metadata. If no metadata was previously set, returns null by default.
String get_tab_title(tab_idx: int) const 🔗
Returns the title of the tab at index tab_idx. Tab titles default to the name of the indexed child node, but this can be overridden with set_tab_title.
String get_tab_tooltip(tab_idx: int) const 🔗
Returns the tooltip text of the tab at index tab_idx.
bool is_tab_disabled(tab_idx: int) const 🔗
Returns true if the tab at index tab_idx is disabled.
Returns true if the tab at index tab_idx is hidden.
bool select_next_available() 🔗
Selects the first available tab with greater index than the currently selected. Returns true if tab selection changed.
bool select_previous_available() 🔗
Selects the first available tab with lower index than the currently selected. Returns true if tab selection changed.
void set_popup(popup: Node) 🔗
If set on a Popup node instance, a popup menu icon appears in the top-right corner of the TabContainer (setting it to null will make it go away). Clicking it will expand the Popup node.
Sets the button icon from the tab at index tab_idx.
void set_tab_disabled(tab_idx: int, disabled: bool) 🔗
If disabled is true, disables the tab at index tab_idx, making it non-interactable.
If hidden is true, hides the tab at index tab_idx, making it disappear from the tab area.
void set_tab_icon(tab_idx: int, icon: Texture2D) 🔗
Sets an icon for the tab at index tab_idx.
void set_tab_icon_max_width(tab_idx: int, width: int) 🔗
Sets the maximum allowed width of the icon for the tab at index tab_idx. This limit is applied on top of the default size of the icon and on top of icon_max_width. The height is adjusted according to the icon's ratio.
void set_tab_metadata(tab_idx: int, metadata: Variant) 🔗

Space between tab's name and its icon.
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.
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.
The font used to draw tab names.
Font size of the tab names.
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.
Icon shown to indicate where a dragged tab is gonna be dropped (see drag_to_rearrange_enabled).
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.

The icon for the menu button (see set_popup) when it's being hovered with the cursor.
The style for the background fill.
The style of disabled tabs.
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.
The style of the currently hovered tab.
Note: This style will be drawn with the same width as tab_unselected at minimum.
The style of the currently selected tab.
The style of the other, unselected tabs.
StyleBox tabbar_background 🔗
The style for the background fill of the TabBar area.
