TabContainer

Inherits: Container < Control < CanvasItem < Node < Object

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

描述

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.

信号

active_tab_rearranged ( int idx_to )

Emitted when the active tab is rearranged via mouse drag. See drag_to_rearrange_enabled.

pre_popup_pressed ( )

tab_button_pressed ( int tab )

Emitted when the user clicks on the button icon on this tab.

tab_changed ( int tab )

Emitted when switching to another tab.

tab_clicked ( int tab )

Emitted when a tab is clicked, even if it is the current tab.

Property Descriptions

bool all_tabs_in_front = false

  • void set_all_tabs_in_front ( bool value )

  • bool is_all_tabs_in_front ( )

If true, all tabs are drawn in front of the panel. If false, inactive tabs are drawn behind the panel.

bool clip_tabs = true

  • void set_clip_tabs ( bool value )

  • bool get_clip_tabs ( )

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.

int current_tab = 0

  • void set_current_tab ( int value )

  • 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.

bool drag_to_rearrange_enabled = false

  • void set_drag_to_rearrange_enabled ( bool value )

  • bool get_drag_to_rearrange_enabled ( )

If true, tabs can be rearranged with mouse drag.

AlignmentMode tab_alignment = 0

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

int tabs_rearrange_group = -1

  • void set_tabs_rearrange_group ( int value )

  • int get_tabs_rearrange_group ( )

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.

bool tabs_visible = true

  • void set_tabs_visible ( bool value )

  • bool are_tabs_visible ( )

If true, tabs are visible. If false, tabs' content and titles are hidden.

bool use_hidden_tabs_for_min_size = false

  • void set_use_hidden_tabs_for_min_size ( bool value )

  • bool get_use_hidden_tabs_for_min_size ( )

If true, children 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.

Popup get_popup ( ) const

Returns 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 get_previous_tab ( ) const

Returns the previously active tab index.

Texture2D get_tab_button_icon ( int tab_idx ) const

Returns the button icon from the tab at index tab_idx.

Control get_tab_control ( int tab_idx ) const

Returns the Control node from the tab at index tab_idx.

int get_tab_count ( ) const

Returns the number of tabs.

Texture2D get_tab_icon ( int tab_idx ) const

Returns the Texture2D for the tab at index tab_idx or null if the tab has no Texture2D.

int get_tab_idx_at_point ( Vector2 point ) const

Returns the index of the tab at local coordinates point. Returns -1 if the point is outside the control boundaries or if there's no tab at the queried position.

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 ( int tab_idx ) 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 ( int tab_idx ) 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.

bool is_tab_disabled ( int tab_idx ) const

Returns true if the tab at index tab_idx is disabled.

bool is_tab_hidden ( int tab_idx ) const

Returns true if the tab at index tab_idx is hidden.

void set_popup ( Node popup )

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.

void set_tab_button_icon ( int tab_idx, Texture2D icon )

Sets the button icon from the tab at index tab_idx.

void set_tab_disabled ( int tab_idx, bool disabled )

If disabled is true, disables the tab at index tab_idx, making it non-interactable.

void set_tab_hidden ( int tab_idx, bool hidden )

If hidden is true, hides the tab at index tab_idx, making it disappear from the tab area.

void set_tab_icon ( int tab_idx, Texture2D icon )

Sets an icon for the tab at index tab_idx.

void set_tab_metadata ( int tab_idx, Variant metadata )

Sets the metadata value for the tab at index tab_idx, which can be retrieved later using get_tab_metadata.

void set_tab_title ( int tab_idx, String title )

Sets a custom title for the tab at index tab_idx (tab titles default to the name of the indexed child node). Set it back to the child's name to make the tab default to it again.

Theme Property Descriptions

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

Modulation color for the drop_mark icon.

Color font_disabled_color = Color(0.875, 0.875, 0.875, 0.5)

Font color of disabled tabs.

Color font_hovered_color = Color(0.95, 0.95, 0.95, 1)

Font color of the currently hovered tab.

Color font_outline_color = Color(1, 1, 1, 1)

The tint of text outline of the tab name.

Color font_selected_color = Color(0.95, 0.95, 0.95, 1)

Font color of the currently selected tab.

Color font_unselected_color = Color(0.7, 0.7, 0.7, 1)

Font color of the other, unselected tabs.

int icon_max_width = 0

The 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

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.

Texture2D drop_mark
