There are models for -the actual table contents and for the table headers; they are the -actual repository of information. - -The objects are rendered by various view objects. In the current code -base, we use we use GnomeCanvasItems to do the rendering. One for -each table and one for the headers. - -* The main widget - -e-table.c, e-table.h: - - Implements a full widget. Uses various components described - below. Handles column display as well as grouping/nesting - -* The Models - -All of them are GtkObjects. - -e-table-model.h, e-table-model.c: - - These implement the abstract E-Table-Model class. You - can derive this object to create your own data repository. - - These emits signals to notify the views about selection, and - changes in the model. - -e-table-simple.h, e-table-simple.c: - - A simple implementation of e-table-model that uses callback - routines (you provide the callbacks). For lazy people, like - me. - -e-cell.c, e-cell.h: - - These are actually mis-named. Objects of type e-cell know - about rendering a single cell, and these are attached to the - e-table-cols (described next). - - The user provides the various rendering modes as e-cells (they - are actually column-rendering repositories). - - This is just an abstract class. I will provide various - e-cells: a text cell, a checkbox cell, an image cell, and - perhaps an n-state image cell (one that switches the image when - the cell is clicked). - -e-table-col.h, e-table-col.c: - - Describes a single column (the size, the string displayed, the - rendering function for each row and comparison function for - this field). - - -* The Views - -e-table-header.h, e-table-header.c: - - These implement the ETableHeaderItem canvas item. This item is - used both to control the columns displayed as well as displaying them. - - They describe what columns are shown in the screen and in - which order. - - These emit signals: column-size-changed and structure-changed - (if a column is added/removed) - -e-table-item.c, e-table-item.h - - This is a canvas item that renders the contents of a - ETableModel into the screen. - -e-table-header-item.c, e-table-header-item.h - - This canvas item renders the ETableHeader headings. - -e-cell-text.c, e-cell-text.h - - Not really a view, but actually a derivative of e-cell that - implements text display: supports justification and font - setting. Will add color in the future most likely - -e-cell-toggle.c, e-cell-toggle.h - - A derivative of e-cell as well that support N-toggle values - using images. - -e-cell-check.c, e-cell-check.h - - An e-cell-toggle with two states only (for checkboxes). - -* The Filters - -e-table-sorted.c, e-table-sorted.h - - This is an ETableModel that can sort an existing ETableModel. - -e-table-subset.c, e-table-subset.h - - Not finished, but it is just an ETableModel that happens to be - a subset of another ETableModel. - -* Everything - -e-table.c, e-table.h - - In the future these guys will implement the whole widget for - doing table editing. Nothing done about these yet. |
