/**
|
|
* Adapter class in the component selector Model-View-Adapter (mediated MVC)
|
|
* architecture. The other pieces are in:
|
|
*
|
|
* - Model: CMP_TREE_NODE and descendants in eeschema/cmp_tree_model.h
|
|
* - View:
|
|
* - DIALOG_CHOOSE_COMPONENT in eeschema/dialogs/dialog_choose_component.h
|
|
* - wxDataViewCtrl
|
|
*
|
|
* This adapter presents the interface specified by wxDataViewModel to the
|
|
* wxDataViewCtrl:
|
|
*
|
|
* +---+ +------------------+
|
|
* +---+ Generates | A | | VIEW |
|
|
* | M | from libs | D | wxDataViewModel |------------------|
|
|
* | O | <---------- | A | <------------------> | wxDataViewCtrl |
|
|
* | D | | P | |------------------|
|
|
* | E | <---------> | T | <------------------- | wxTextCtrl |
|
|
* | L | UpdateScore | E | UpdateSearchString() |------------------|
|
|
* +---+ | R | | |
|
|
* +---+ +------------------+
|
|
*
|
|
* Because this adapter is a wxDataViewModel, it is reference-counted by
|
|
* wxObject. To ensure this interface is used correctly, the constructor
|
|
* is private; LIB_TREE_MODEL_ADAPTER should be created by the static
|
|
* factory method LIB_TREE_MODEL_ADAPTER::Create().
|
|
*
|
|
* Quick summary of methods used to drive this class:
|
|
*
|
|
* - `SetFilter()` - set whether the view is restricted to power parts
|
|
* - `ShowUnits()` - set whether units are displayed
|
|
* - `SetPreselectNode()` - set a node to highlight when not searching
|
|
* - `AddLibrary()` - populate the model with all aliases in a library
|
|
* - `AddAliasList()` - populate the model with a specific list of aliases
|
|
*
|
|
* Quick summary of methods used by the View:
|
|
*
|
|
* - `UpdateSearchString()` - pass in the user's search text
|
|
* - `AttachTo()` - pass in the wxDataViewCtrl
|
|
* - `GetAliasFor()` - get the LIB_ALIAS* for a selected item
|
|
* - `GetUnitFor()` - get the unit for a selected item
|
|
* - `GetComponentsCount()` - count the aliases loaded
|
|
*
|
|
* Methods implemented as part of wxDataViewModel:
|
|
*
|
|
* - `HasContainerColumns()` - whether a parent item has more than one column
|
|
* - `IsContainer()` - whether an item is a parent
|
|
* - `GetParent()` - return the parent of an item, or invalid if root
|
|
* - `GetChildren()` - get the children of an item
|
|
* - `GetColumnCount()` - get the number of columns in the view
|
|
* - `GetColumnType()` - get the data type shown in each column
|
|
* - `GetValue()` - get the data shown in a cell
|
|
* - `SetValue()` - edit the data in a cell (does nothing)
|
|
* - `GetAttr()` - get any per-item formatting
|
|
* - `Compare()` - compare two rows, for sorting
|
|
* - `HasDefaultCompare()` - whether sorted by default
|
