TabContainer
Inherits Container
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.
Properties
bool all_tabs_in_front = false
bool all_tabs_in_front = falseIf true, all tabs are drawn in front of the panel. If false, inactive tabs are drawn behind the panel.
bool clip_tabs = true
bool clip_tabs = trueIf 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.
int current_tab = -1
int current_tab = -1The 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
bool deselect_enabled = falseIf 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
bool drag_to_rearrange_enabled = falseIf true, tabs can be rearranged with mouse drag.
int tab_alignment = 0
int tab_alignment = 0The position at which tabs will be placed.
int tab_focus_mode = 2
int tab_focus_mode = 2The focus access mode for the internal TabBar node.
int tabs_position = 0
int tabs_position = 0The position of the tab bar.
int tabs_rearrange_group = -1
int tabs_rearrange_group = -1TabContainers 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.
bool tabs_visible = true
bool tabs_visible = trueIf true, tabs are visible. If false, tabs' content and titles are hidden.
bool use_hidden_tabs_for_min_size = false
bool use_hidden_tabs_for_min_size = falseIf true, child Control nodes that are hidden have their minimum size take into account in the total, instead of only the currently visible one.
Methods
Control get_current_tab_control() const
Control get_current_tab_control() constReturns the child Control node located at the active tab index.
Popup get_popup() const
Popup get_popup() constReturns the Popup node instance if one has been set already with set_popup(). Warning: This is a required internal node, removing and freeing it may cause a crash. If you wish to hide it or any of its children, use their Window.visible property.

int icon_max_width = 0The maximum allowed width of the tab's icon. This limit is applied on top of the default size of the icon, but before the value set with TabBar.set_tab_icon_max_width(). The height is adjusted according to the icon's ratio.
int icon_separation = 4
int icon_separation = 4Space between tab's name and its icon.
int outline_size = 0
int outline_size = 0The 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
int side_margin = 8The 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.
int tab_separation = 0
int tab_separation = 0The space between tabs in the tab bar.
Font font
Font fontThe font used to draw tab names.
int font_size
int font_sizeFont size of the tab names.
Texture2D decrement
Texture2D decrementIcon 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
Texture2D decrement_highlightIcon 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
Texture2D drop_markIcon shown to indicate where a dragged tab is gonna be dropped (see drag_to_rearrange_enabled).
Texture2D increment
Texture2D incrementIcon 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
Texture2D increment_highlightIcon 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
Texture2D menuThe icon for the menu button (see set_popup()).
Texture2D menu_highlight

StyleBox panel
StyleBox panelThe style for the background fill.
StyleBox tab_disabled
StyleBox tab_disabledThe style of disabled tabs.
StyleBox tab_focus
StyleBox tab_focusStyleBox 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
StyleBox tab_hoveredThe style of the currently hovered tab. Note: This style will be drawn with the same width as tab_unselected at minimum.
StyleBox tab_selected
StyleBox tab_selectedThe style of the currently selected tab.
StyleBox tab_unselected
StyleBox tab_unselectedThe style of the other, unselected tabs.
StyleBox tabbar_background
StyleBox tabbar_backgroundThe style for the background fill of the TabBar area.
