virtual bool irr::gui::IGUITreeView::getImageLeftOfIcon | ( |  | ) | const`[pure virtual]`

Returns if the Image is left of the icon. Default is true.

virtual IGUIImageList* irr::gui::IGUITreeView::getImageList | ( |  | ) | const`[pure virtual]`

Returns the image list which is used for the nodes.

virtual IGUITreeViewNode* irr::gui::IGUITreeView::getLastEventNode | ( |  | ) | const`[pure virtual]`

Returns the node which is associated to the last event.

This pointer is only valid inside the OnEvent call!

virtual bool irr::gui::IGUITreeView::getLinesVisible | ( |  | ) | const`[pure virtual]`

returns true if the tree lines are visible

virtual IGUITreeViewNode* irr::gui::IGUITreeView::getRoot | ( |  | ) | const`[pure virtual]`

returns the root node (not visible) from the tree.

virtual IGUITreeViewNode* irr::gui::IGUITreeView::getSelected | ( |  | ) | const`[pure virtual]`

returns the selected node of the tree or 0 if none is selected

virtual void irr::gui::IGUITreeView::setIconFont | ( | IGUIFont * | font | ) | `[pure virtual]`

Sets the font which should be used as icon font.

This font is set to the Irrlicht engine built-in-font by default. Icons can be displayed in front of every list item. An icon is a string, displayed with the icon font. When using the build-in-font of the Irrlicht engine as icon font, the icon strings defined in GUIIcons.h can be used.

virtual void irr::gui::IGUITreeView::setImageLeftOfIcon | ( | bool | bLeftOf | ) | `[pure virtual]`

Sets if the image is left of the icon. Default is true.

virtual void irr::gui::IGUITreeView::setImageList | ( | IGUIImageList * | imageList | ) | `[pure virtual]`

Sets the image list which should be used for the image and selected image of every node.

The default is 0 (no images).
