Property Descriptions

Setter

set_collapsed(value)

Getter

is_collapsed()

If true, the TreeItem is collapsed.


  • int custom_minimum_height

Setter

set_custom_minimum_height(value)

Getter

get_custom_minimum_height()

The custom minimum height.


  • bool disable_folding

Setter

set_disable_folding(value)

Method Descriptions

Adds a button with Texture2D button at column column. The button_idx index is used to identify the button when calling other methods. If not specified, the next available index is used, which may be retrieved by calling get_button_count immediately after this method. Optionally, the button can be disabled and have a tooltip.


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.


  • void clear_opentype_features ( int column )

Removes all OpenType features.


Creates an item and adds it as a child.

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


  • void deselect ( int column )

Deselects the given column.


  • void erase_button ( int column, int button_idx )

Removes the button at index button_idx in column column.


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


  • int get_button_count ( int column ) const

Returns the number of buttons in column column. May be used to get the most recently added button's index, if no index was specified.


  • String get_button_tooltip ( int column, int button_idx ) const

Returns the tooltip string for the button at index button_idx in column column.


Returns the column's cell mode.


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.


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.


Returns the TreeItem's first child.


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.


Returns item's text language code.


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


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


Returns the next visible 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.


Returns OpenType feature tag of the item's text.


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


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


Returns the previous visible 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.


Returns the value of a CELL_MODE_RANGE column.


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



  • Array get_structured_text_bidi_override_options ( int column ) const


Gets the suffix string shown after the column value.


Returns the given column's text.


Returns the given column's text alignment.


Returns item's text base writing direction.


Returns the given column's tooltip.


  • Tree get_tree ( ) const

Returns the Tree that owns this TreeItem.


  • bool is_button_disabled ( int column, int button_idx ) const

Returns true if the button at index button_idx for the given column is disabled.

Note: You can't move to the root or move the root.


  • void remove_child ( Object child )
