|
|
/// Similar to Fl_Browser, Fl_Tree is a browser of Fl_Tree_Item's arranged
|
|
/// in a parented hierarchy, or 'tree'. Subtrees can be expanded or closed.
|
|
/// Items can be added, deleted, inserted, sorted and re-ordered.
|
|
///
|
|
/// The tree items may also contain other FLTK widgets, like buttons, input fields,
|
|
/// or even "custom" widgets.
|
|
///
|
|
/// The callback() is invoked depending on the value of when():
|
|
///
|
|
/// - FL_WHEN_RELEASE -- callback invoked when left mouse button is released on an item
|
|
/// - FL_WHEN_CHANGED -- callback invoked when left mouse changes selection state
|
|
///
|
|
/// The simple way to define a tree:
|
|
/// \code
|
|
/// #include <FL/Fl_Tree.H>
|
|
/// [..]
|
|
/// Fl_Tree tree(X,Y,W,H);
|
|
/// tree.begin();
|
|
/// tree.add("Flintstones/Fred");
|
|
/// tree.add("Flintstones/Wilma");
|
|
/// tree.add("Flintstones/Pebbles");
|
|
/// tree.add("Simpsons/Homer");
|
|
/// tree.add("Simpsons/Marge");
|
|
/// tree.add("Simpsons/Bart");
|
|
/// tree.add("Simpsons/Lisa");
|
|
/// tree.end();
|
|
/// \endcode
|
|
///
|
|
/// \b FEATURES
|
|
///
|
|
/// Items can be added with add(),
|
|
/// removed with remove(),
|
|
/// completely cleared with clear(),
|
|
/// inserted with insert() and insert_above(),
|
|
/// selected/deselected with select() and deselect(),
|
|
/// open/closed with open() and closed().
|
|
/// Children of an item can be swapped around with Fl_Tree_Item::swap_children(),
|
|
/// sorting can be controlled when items are add()ed via sortorder().
|
|
/// You can walk the entire tree with first() and next().
|
|
/// You can walk selected items with first_selected_item() and
|
|
/// next_selected_item().
|
|
/// Items can be found by their pathname using find_item(const char*),
|
|
/// and an item's pathname can be found with item_pathname().
|
|
/// The selected items' colors are controlled by selection_color() (inherited from Fl_Widget).
|
|
///
|
|
/// \b SELECTION OF ITEMS
|
|
///
|
|
/// The tree can have different selection behaviors controlled by selectmode().
|
|
/// The background color used for selected items is the Fl_Tree::selection_color().
|
|
/// The foreground color for selected items is controlled internally with fl_contrast().
|
|
///
|
|
/// \b CHILD WIDGETS
|
|
///
|
|
/// FLTK widgets (including custom widgets) can be assigned to tree items via
|
|
/// Fl_Tree_Item::widget().
|
|
///
|
|
/// When a widget() is defined, the default behavior is for the widget()
|
|
/// to be shown in place of the item's label (if it has one).
|
|
/// Only the widget()'s width will be used; the widget()'s x() and y() position
|
|
/// will be managed by the tree, and the h() will track the item's height.
|
|
/// This default behavior can be altered:
|
|
/// Setting Fl_Tree::item_draw_mode()'s FL_TREE_ITEM_DRAW_LABEL_AND_WIDGET flag
|
|
/// causes the label + widget to be displayed together in that order, and
|
|
/// adding the FL_TREE_ITEM_HEIGHT_FROM_WIDGET flag causes widget's height
|
|
/// to define the widget()'s height.
|
|
///
|
|
/// \b ICONS
|
|
///
|
|
/// The tree's open/close icons can be redefined with
|
|
/// Fl_Tree::openicon(), Fl_Tree::closeicon(). User icons
|
|
/// can either be changed globally with Fl_Tree::usericon(),
|
|
/// or on a per-item basis with Fl_Tree_Item::usericon().
|
|
///
|
|
/// Various default preferences can be globally manipulated via Fl_Tree_Prefs,
|
|
/// including colors, margins, icons, connection lines, etc.
|
|
///
|
|
/// \b FONTS AND COLORS
|
|
///
|
|
/// When adding new items to the tree, the new items get the
|
|
/// defaults for fonts and colors from:
|
|
///
|
|
/// - Fl_Tree::item_labelfont() -- The default item label font (default: FL_HELVETICA)
|
|
/// - Fl_Tree::item_labelsize() -- The default item label size (default: FL_NORMAL_SIZE)
|
|
/// - Fl_Tree::item_labelfgcolor() -- The default item label foreground color (default: FL_FOREGROUND_COLOR)
|
|
/// - Fl_Tree::item_labelbgcolor() -- The default item label background color (default: 0xffffffff, which tree uses as 'transparent')
|
|
///
|
|
/// Each item (Fl_Tree_Item) inherits a copy of these font/color attributes when created,
|
|
/// and each item has its own methods to let the app change these values on a per-item basis
|
|
/// using methods of the same name:
|
|
///
|
|
/// - Fl_Tree_Item::item_labelfont() -- The item's label font (default: FL_HELVETICA)
|
|
/// - Fl_Tree_Item::item_labelsize() -- The item's label size (default: FL_NORMAL_SIZE)
|
|
/// - Fl_Tree_Item::item_labelfgcolor() -- The item's label foreground color (default: FL_FOREGROUND_COLOR)
|
|
/// - Fl_Tree_Item::item_labelbgcolor() -- The item's label background color (default: 0xffffffff, which tree uses as 'transparent')
|
|
///
|
|
/// \b CALLBACKS
|
|
///
|
|
/// The tree's callback() will be invoked when items change state or are open/closed.
|
|
/// when() controls when mouse/keyboard events invoke the callback.
|
|
/// callback_item() and callback_reason() can be used to determine the cause of the callback. eg:
|
|
///
|
|
/// \code
|
|
/// void MyTreeCallback(Fl_Widget *w, void *data) {
|
|
/// Fl_Tree *tree = (Fl_Tree*)w;
|
|
/// Fl_Tree_Item *item = (Fl_Tree_Item*)tree->callback_item(); // get selected item
|
|
/// switch ( tree->callback_reason() ) {
|
|
/// case FL_TREE_REASON_SELECTED: [..]
|
|
/// case FL_TREE_REASON_DESELECTED: [..]
|
|
/// case FL_TREE_REASON_RESELECTED: [..]
|
|
/// case FL_TREE_REASON_OPENED: [..]
|
|
/// case FL_TREE_REASON_CLOSED: [..]
|
|
/// }
|
|
/// \endcode
|
|
///
|
|
/// To get the item's full menu pathname, you can use Fl_Tree::item_pathname(), eg:
|
|
///
|
|
/// \code
|
|
/// char pathname[256] = "???";
|
|
/// tree->item_pathname(pathname, sizeof(pathname), item); // eg. "Parent/Child/Item"
|
|
/// \endcode
|
|
///
|
|
/// To walk all the items of the tree from top to bottom:
|
|
/// \code
|
|
/// // Walk all the items in the tree, and print their labels
|
|
/// for ( Fl_Tree_Item *item = tree->first(); item; item = tree->next(item) ) {
|
|
/// printf("Item: %s\n", item->label());
|
|
/// }
|
|
/// \endcode
|
|
///
|
|
/// To recursively walk all the children of a particular item,
|
|
/// define a function that uses recursion:
|
|
/// \code
|
|
/// // Find all of the item's children and print an indented report of their labels
|
|
/// void my_print_all_children(Fl_Tree_Item *item, int indent=0) {
|
|
/// for ( int t=0; t<item->children(); t++ ) {
|
|
/// printf("%*s Item: %s\n", indent, "", item->child(t)->label());
|
|
/// my_print_all_children(item->child(t), indent+4); // recurse
|
|
/// }
|
|
/// }
|
|
/// \endcode
|
|
///
|
|
/// To change the default label font and color for creating new items:
|
|
/// \code
|
|
/// tree = new Fl_Tree(..);
|
|
/// tree->item_labelfont(FL_COURIER); // Use Courier font for all new items
|
|
/// tree->item_labelfgcolor(FL_RED); // Use red color for labels of all new items
|
|
/// [..]
|
|
/// // Now create the items in the tree using the above defaults.
|
|
/// tree->add("Aaa");
|
|
/// tree->add("Bbb");
|
|
/// [..]
|
|
/// \endcode
|
|
///
|
|
/// To change the font and color of all items in the tree:
|
|
/// \code
|
|
/// // Change the font and color of all items currently in the tree
|
|
/// for ( Fl_Tree_Item *item = tree->first(); item; item = tree->next(item) ) {
