Property Descriptions¶

bool collapsed

bool is_collapsed ( )

If true, the TreeItem is collapsed.

int custom_minimum_height

Method Descriptions¶

void add_button ( int column, Texture2D button, int id=-1, bool disabled=false, String tooltip_text="" )

Adds a button with Texture2D button at column column. The id is used to identify the button in the according Tree.button_clicked signal and can be different from the buttons index. If not specified, the next available index is used, which may be retrieved by calling get_button_count immediately before this method. Optionally, the button can be disabled and have a tooltip_text.

void call_recursive ( StringName method, ... ) vararg

Calls the method on the actual TreeItem and its children recursively. Pass parameters as a comma separated list.

void clear_custom_bg_color ( int column )

Resets the background color for the given column to default.

void clear_custom_color ( int column )

Resets the color for the given column to default.

TreeItem create_child ( int index=-1 )

Creates an item and adds it as a child.

The new item will be inserted as position index (the default value -1 means the last position), or it will be the last child if index is higher than the child count.

void deselect ( int column )

Deselects the given column.

void erase_button ( int column, int button_index )

Removes the button at index button_index in column column.

Texture2D get_button ( int column, int button_index ) const

Returns the Texture2D of the button at index button_index in column column.

int get_button_by_id ( int column, int id ) const

Returns the button index if there is a button with ID id in column column, otherwise returns -1.

int get_button_count ( int column ) const

Returns the number of buttons in column column.

int get_button_id ( int column, int button_index ) const

Returns the ID for the button at index button_index in column column.

Returns the tooltip text for the button at index button_index in column column.

TreeCellMode get_cell_mode ( int column ) const

Returns the column's cell mode.

TreeItem get_child ( int index )

Returns a child item by its index (see get_child_count). This method is often used for iterating all children of an item.

Negative indices access the children from the last one.

int get_child_count ( )

Returns the number of child items.

TreeItem[] get_children ( )

Returns an array of references to the item's children.

Color get_custom_bg_color ( int column ) const

Returns the custom background color of column column.

Color get_custom_color ( int column ) const

Returns the custom color of column column.

Font get_custom_font ( int column ) const

Returns custom font used to draw text in the column column.

int get_custom_font_size ( int column ) const

Returns custom font size used to draw text in the column column.

bool get_expand_right ( int column ) const

Returns true if expand_right is set.

TreeItem get_first_child ( ) const

Returns the TreeItem's first child.

Texture2D get_icon ( int column ) const

Returns the given column's icon Texture2D. Error if no icon is set.

int get_icon_max_width ( int column ) const

Returns the column's icon's maximum width.

Color get_icon_modulate ( int column ) const

Returns the Color modulating the column's icon.

Rect2 get_icon_region ( int column ) const

Returns the icon Texture2D region as Rect2.

int get_index ( )

Returns the node's order in the tree. For example, if called on the first child item the position is 0.

String get_language ( int column ) const

Returns item's text language code.

Variant get_metadata ( int column ) const

Returns the metadata value that was set for the given column using set_metadata.

TreeItem get_next ( ) const

Returns the next sibling TreeItem in the tree or a null object if there is none.

TreeItem get_next_visible ( bool wrap=false )

Returns the next visible sibling TreeItem in the tree or a null object if there is none.

If wrap is enabled, the method will wrap around to the first visible element in the tree when called on the last visible element, otherwise it returns null.

TreeItem get_parent ( ) const

Returns the parent TreeItem or a null object if there is none.

TreeItem get_prev ( )

Returns the previous sibling TreeItem in the tree or a null object if there is none.

TreeItem get_prev_visible ( bool wrap=false )

Returns the previous visible sibling TreeItem in the tree or a null object if there is none.

If wrap is enabled, the method will wrap around to the last visible element in the tree when called on the first visible element, otherwise it returns null.

float get_range ( int column ) const

Returns the value of a CELL_MODE_RANGE column.

Dictionary get_range_config ( int column )

Returns a dictionary containing the range parameters for a given column. The keys are "min", "max", "step", and "expr".

It is possible to process the items affected by this method call by connecting to Tree.check_propagated_to_item. The order that the items affected will be processed is as follows: the item invoking this method, children of that item, and finally parents of that item.
