/**
|
|
* @defgroup NestedWidgets Hierarchical widgets
|
|
* Hierarchical widgets, also known as nested widgets, are widgets stored in a tree. At the leafs of the tree are (mostly) the 'real' widgets
|
|
* visible to the user. At higher levels, widgets get organized in container widgets, until all widgets of the window are merged.
|
|
*
|
|
* \section nestedwidgetkinds Hierarchical widget kinds
|
|
* A leaf widget is one of
|
|
* <ul>
|
|
* <li> #NWidgetLeaf for widgets visible for the user, or
|
|
* <li> #NWidgetSpacer for creating (flexible) empty space between widgets.
|
|
* </ul>
|
|
* The purpose of a leaf widget is to provide interaction with the user by displaying settings, and/or allowing changing the settings.
|
|
*
|
|
* A container widget is one of
|
|
* <ul>
|
|
* <li> #NWidgetHorizontal for organizing child widgets in a (horizontal) row. The row switches order depending on the language setting (thus supporting
|
|
* right-to-left languages),
|
|
* <li> #NWidgetHorizontalLTR for organizing child widgets in a (horizontal) row, always in the same order. All childs below this container will also
|
|
* never swap order.
|
|
* <li> #NWidgetVertical for organizing child widgets underneath each other.
|
|
* <li> #NWidgetBackground for adding a background behind its child widget.
|
|
* <li> #NWidgetStacked for stacking child widgets on top of each other.
|
|
* </ul>
|
|
* The purpose of a container widget is to structure its leafs and sub-containers to allow proper resizing.
|
|
*
|
|
* \section nestedwidgetscomputations Hierarchical widget computations
|
|
* The first 'computation' is the creation of the nested widgets tree by calling the constructors of the widgets listed above and calling \c Add() for every child,
|
|
* or by means of specifying the tree as a collection of nested widgets parts and instantiating the tree from the array.
|
|
*
|
|
* After the creation step,
|
|
* - The leafs have their own minimal size (\e min_x, \e min_y), filling (\e fill_x, \e fill_y), and resize steps (\e resize_x, \e resize_y).
|
|
* - Containers only know what their children are, \e fill_x, \e fill_y, \e resize_x, and \e resize_y are not initialized.
|
|
*
|
|
* Computations in the nested widgets take place as follows:
|
|
* <ol>
|
|
* <li> A bottom-up sweep by recursively calling NWidgetBase::SetupSmallestSize() to initialize the smallest size (\e smallest_x, \e smallest_y) and
|
|
* to propagate filling and resize steps upwards to the root of the tree.
|
|
* <li> A top-down sweep by recursively calling NWidgetBase::AssignSizePosition() with #ST_SMALLEST to make the smallest sizes consistent over
|
|
* the entire tree, and to assign the top-left (\e pos_x, \e pos_y) position of each widget in the tree. This step uses \e fill_x and \e fill_y at each
|
|
* node in the tree to decide how to fill each widget towards consistent sizes. Also the current size (\e current_x and \e current_y) is set.
|
|
* <li> After initializing the smallest size in the widget tree with #ST_SMALLEST, the tree can be resized (the current size modified) by calling
|
|
* NWidgetBase::AssignSizePosition() at the root with #ST_RESIZE and the new size of the window. For proper functioning, the new size should be the smallest
|
|
* size + a whole number of resize steps in both directions (ie you can only resize in steps of length resize_{x,y} from smallest_{x,y}).
|
|
* </ol>
|
|
* After the second step, the current size of the widgets are set to the smallest size.
|
|
*
|
|
* To resize, perform the last step with the new window size. This can be done as often as desired.
|
|
* When the smallest size of at least one widget changes, the whole procedure has to be redone from the start.
