class EV_GRID General cluster: interface description: "Widget which is a combination of an EV_TREE and an EV_MULTI_COLUMN_LIST. Item Insertion: The grid is an item holder for objects of type EV_GRID_ITEM and its descendents. Each grid item may be inserted in to the grid at a specific column and row. An item itself may be added to the grid via set_item, which takes a column and row index. Items be also added via the set_item routine of the row (EV_GRID_ROW) and column (EV_GRID_COLUMN) objects contained within Current. Items inserted may be Void if necessary, this may be useful to blank out any existing items set. If a grid contains no items and therefore has no rows or columns, inserting an item will dynamically resize and automatically create the columns and rows so that it can contain and display the newly inserted item. New columns and rows may also be added to the grid via insert_new_column and insert_new_row respectively. -------------------------------------------------------------------------------- Dynamic Mode: There may be times where you have very large numbers of items you wish to display into the grid. Unfortunately, the overhead of building thousands and thousands of grid items and inserting them can take a considerable amount of which shows up as a delay to users of the system. To prevent this, the grid supports the use of a dynamic mode which permit you to specify how many items are contained and then as and when the grid requires access to one of these items for display purposes, an event is triggered requesting the item to be displayed. dynamic content is enabled via enable_partial_dynamic_content. In this mode whenever the grid attempts to draw an item that is Void, it queries you for the item and then inserts it into the grid. The grid requests an item in the dynamic mode through the calling of the dynamic_content_function which may be set via a call to set_dynamic_content_function. This function has two integer arguments corresponding to the column and row index of the desired item and a return type of EV_GRID_ITEM. -------------------------------------------------------------------------------- Size and Position: The grid is comprised of the following graphical elements: 1. A header displayed at the top of Current which may be hidden/shown via show_header and hide_header'. 2. A viewable area in which the contents of Current are displayed, displayed immediately below the header. The size of this area is given by viewable_width and viewable_height with its position relative to the top left corner of Current given by viewable_x_offset, viewable_y_offset. Note that viewable_y_offset changes based on the visible state of the header. 3. A horizontal scroll bar displayed below the viewable area, only shown if the virtual width of Current is greater than viewable_width. 4. A vertical scroll bar displayed to the right of viewable area and header, only shown if the virtual height of Current is greater than viewable_height. You may supress the displaying of the scroll bars if required via calls to hide_vertical_scroll_bar and hide_horizontal_scroll_bar which ensure that the scroll bars are never displayed. This is useful for situations where you wish to control the virtual position of the grid via your own custom interface. The virtual size of the grid represents the complete screen area in pixels required to display the contents of Current and may be queried via virtual_width and virtual_height. If the contents of the grid are smaller than the viewable area, then the virtual size is equal to the viewable area, otherwise an area of the virtual size is displayed within viewable area, with the coordinates of this area (relative to the top left corner) within the virtual size given by virtual_x and virtual_y. As the scroll bars are moved, virtual_x and virtual_y are directly manipulated, although you may set the virtual position explicitly via calls to set_virtual_x and set_virtual_y. The maximum permitted virtual position of the grid is given by maximum_virtual_x_position, maximum_virtual_y_position which is dependent on the following factors: The viewable area of the grid. The virtual_width and virtual_height. The is_*_scrolling_per_item properties. The is_*_overscroll_enabled properties. Changing one or more of these properties may immediately change the virtual width, height or maximum virtual positions, and possibly scroll the grid to ensure that the current virtual position is within the new bounds. The properties is_vertical_overscroll_enabled and is_horizontal_overscroll_enabled permit you to ensure the grid permits scrolling past the final item, ensuring that there is trailing space matching the viewable dimension of the grid less the dimension of the final item. You may query the virtual position of an item within the virtual area of Current via virtual_x_position and virtual_y_position directly on the item. You may also query the dimensions of an item via width and height. It is important to note that for an item that is part of a tree structure, the width may not be equal to column.width and the virtual_x_position may not be equal to column.virtual_x_position. This is because items in tree structures are indented to provide space for the expand/collapse icons as necessary. The number of pixels that the item is indented for this purpose may be queried directly from the item via a call to horizontal_indent. You may query the virtual y position of a row within Current via virtual_y_position directly on the row. You may query the virtual x position of a column within Current via virtual_x_position directly on the column. As items, columns or rows are added and removed from Current, the virtual size may change. The virtual position may only change if in this situation, you are removing rows or columns that cause the virtual size to reduce and the virtual position is no longer valid. The grid will automatically adjust the virtua position so that the contents of the viewable area are completely contained within the new virtual position. The height of the rows displayed in Current is dependent on is_row_height_fixed. If True, then all rows are displayed at the same height, goverened by row_height. If False, then the height of the row is goverened by its height property which may differ on an individual row basis. The width of columns is always unique and based on their width property. To determine if a particular item is located at a virtual position, use item_at_virtual_position. You may determine the first and last visible rows via first_visible_row and last_visible_row, while first_visible_column and last_visible_column give the first and last columns visible in Current. For more precise information regarding exactly which rows and columns are displayed, you may query visible_row_indexes and visible_column_indexes. Note that if a tree is enabled via enable_tree, then the contents of visible_row_indexes and visible_column_indexes may not be contiguous. To optimize performance, Current only performs recomputation of the virtual positions of items as strictly necessary, which is normally once just before a redraw. As you may query virtual position information whenever you wish, Current may be forced to perform its recomputation of virtual positions as a result of your query. Each time that you modify something in the grid that may affect a virtual position of an item, the grid must recompute the virtual positions again as required. Therefore, for your code to be optimal, it may be necessary to take this into account. The worst possible case scenario is if you are to iterate from the start of the grid to the end of the grid and modify the state of each item or row during the iteration before querying a virtual position of an object in the grid past the current iteration position. In this situation, it is recommended that you perform a two-pass operation. First perform all of the modifications to the items and then perform all of the queries to virtual positions. The grid is optimized for additions in order so if you are repeatedly adding items and querying their virtual positions, then the performance is far better than if you are continuously inserting items at the start of the grid and querying their virtual positions. Although it is important to be aware of this behavior, you will find that in almost all cases, you have do perform no special optimizations to get good performance within Current. This also aplies to removal of rows. If you have many rows to remove, start with the final rows and iterate towards the first for increased performance. The re-drawing of Current is performed on idle, so if you are performing heavy computation and the grid is not updating, call process_events from EV_APPLICATION in order to force a re-draw. -------------------------------------------------------------------------------- Appearance: Each of the items contained within the grid are sized based on the column and row that they occupy. If is_row_height_fixed is True then the height of the rows is dependent on row_height of Current, otherwise it is dependent on height of the row and each row may occupy a different height. For the first non-Void item of each row, the position of the item is item.horizontal_indent pixels greater than the column in which it is contained. The appearance of each item is dependent on the actual type of the item, but there are a number of ways in which you may modify this at the grid level. post_draw_overlay_function is available, which permits you to draw directly on top of items immediately after they are dwan by the implementation. This is useful for adding custom borders to your items. pre_draw_overlay_function is available, which permits you to draw on top of the background of items, but before any features of that item have been drawn. For example, for grid label items, the background is cleared, then the function is called and then the text and pixmap are drawn. Note that for drawable items, which do not re-draw their background automatically, nothing is drawn before the pre_draw_overlay_function is called. When items are selected in a focused grid, they become highlighted in focused_selection_color and if the grid does not have the focus, non_focused_selection_color is used instead. It is recommended that you use these colors for your own drawable items to maintain consistency within the grid. The selection colors may be modified via set_focused_selection_color and set_non_focused_selection_color. Separators between items may be enabled on the grid via enable_column_separators and enable_row_separators which ensure a single line is drawn between each row and column in separator_color. Use set_separator_color to modify this color. The tree structure of Current is drawn using expand_node_pixmap and collapse_node_pixmap to illustrate the expanded state of rows with subrows. You may use your own pixmaps by calling set_expand_node_pixmap and set_collapse_node_pixmap. The indent applied to each subrow is based on the current width of the node pixmaps + subrow_indent. You may increase this indent by calling set_subrow_indent. The nodes in the tree are connected via lines drawn in the color tree_node_connector_color which may be modified via set_tree_node_connector_color. These connecting lines may also be hidden via a call to hide_tree_node_connectors. During a column resize in Current, the contents of the grid are immediately refreshed. This behavior may be disabled via a call to disable_column_resize_immedite and may be necessary if running the grid on older systems as it is less processor intensive. When not is_column_resize_immediate, the column resizing is only performed when the user completes the resize, but a divider may be shown in Current which indicates its new width during the resizing, by calling enable_resizing_divider. This divider may be solid or dashed, based on the state of is_resizing_divider_solid, settable via enable_resizing_divider_solid or disable_resizing_divider_solid. If you wish to perform multiple updates to the grid, in most cases the graphical update is buffered until the system becomes idle, thereby reducing flicker. However, in some situations, it is possible that the system may become idle during the updates, which may lead to flicker. In situations such as these, you may use lock_update to prevent graphical updates from occurring in the grid until unlock_update is called. While the grid is_locked, no graphical updates of any form are performed. -------------------------------------------------------------------------------- Selection: The grid allows both single and multiple selection handling on an item or row level. When enable_single_item_selection is called, only an single item may be selected by the user when Current is on-screen. Selection may occur either programmatically via the enable_select routine of either the item/column or row or on-screen via mouse or keyboard. This is accompanied with the query is_selected. When a user attempts to select an item or row on-screen the grid attempts to make that item or row more visible to the user so that the text of the item may be read, this will not occur however if the item is currently activated. There are two main selection modes, item selection and row selection. In item selection, single or multiple items may be selected depending on the current selection mode. This can be set with enable_single_item_selection and enable_multiple_item_selection respectively. For each type of selection there are events. Examples of such events are item_select_actions, row_select_actions and column_select_actions, these are fired in Current, with the appropriate object being passed to the action sequence that is selected. item_select_actions will only get executed whilst in either single or multiple item selection mode. For handling selection events during single or multiple row selection modes, row_select_actions should be used. To keep track of deselected items, rows or columns, there is item_deselect_actions, row_deselect_actions and column_deselect_actions respectively. Along with selecting items, they may also be deselected. This can be done programatically via the disable_select routine of either the item/column or row. To query what objects are selected, the following queries are available in Current, selected_items, selected_rows and selected_columns. To turn off any default behavior the following queries are available, disable_selection_key_handling and disable_selection_click_handling, this turns off the ability for the user of the grid to select items via the keyboard or mouse. The routine enable_always_selected makes sure that at least one item or row is selected depending on the mode after the initial selection. This can be handy for implementing widgets that require an item be selected at all times. The selection of the grid may be removed with remove_selection. -------------------------------------------------------------------------------- Item Activation: Activation allows for interactive editing of the contents of an item. By calling activate on an activatable item in response to a user event such as double clicking, the item allows for in-place user editing, for changing things such as text. After changing the item, the user may complete the activation by pressing Enter on the keyboard or by causing the item itself to loose focus. To programmatically cancel any activation, each grid item has a deactivate routine that may be called during the activation. If an activation occurs during a user selection then the grid itself will not attempt to reposition the item so that it is more visible. When an item is activated, the item_activate_actions are fired, this can be used to customize the activation process of a certain item, item_deactivate_actions are fired when the item is deactivated. When an item is deactivated, if the user hasn't cancelled the deactivation then the item's contents are updated. See EV_GRID_EDITABLE_ITEM and EV_GRID_COMBO_ITEM for examples of activatable items that allow for in place editing. -------------------------------------------------------------------------------- Event Handling: The standard set of widget events are inherited from EV_CELL with an additional set of events that are applicable to both Current and the items contained are inherited from EV_GRID_ACTION_SEQUENCES. For example, pointer_button_press_actions is inherited from EV_CELL, while pointer_button_press_item_actions is inherited from EV_GRID_ACTION_SEQUENCES and has an EV_GRID_ITEM as event data specifying the applicable item (if any). The coordinates of the item specific versions use virtual coordinates of Current as their coordinate information, wheras those inherited from EV_CELL use client coordinates as for any other EV_WIDGET. The order of event execution for multiple action sequences that may be triggered by a single event are as follows: 1. The standard inherited widget events are fired. i.e. %"grid.pointer_button_press_actions%" The x and y coordinate event data is relative to the upper left corner of Current. 2. The grid item specific versions of these events are fired. i.e. %"grid.pointer_button_press_item_actions%" The x and y coordinate event data is relative to the upper left corner of the %"item%" area of Current, in virtual grid coordinates. These events are only fired while the mouse pointer is above the %"item%" area (does not include header and scroll bars). 3. The events are fired on the item themselves. i.e. %"item.pointer_button_press_actions%" The x and y coordinate event data is relative to the upper left corner of the item. The grid specific versions of particular events permit you to perform handling for all of your items in a common place and are always fired before the specific item versions. For example, if you connect to both EV_GRID.row_expand_actions and EV_GRID_ROW.expand_actions, the grid version is fired first, immediately by the row version. The action sequences are fired one immediately after the other and both are always fired even if you change states of the target object within the first action sequence. -------------------------------------------------------------------------------- Color Handling: Colors applied to items within Current are determined on a three level basis. The base level is Current whose foreground_color and background_color may never be Void. The second level are the columns and rows of Current whose foreground_color and background_color are Void by default. The final level is comprised of the items of Current themselves whose foreground_color and background_color are Void by default. As Current performs a re-draw of an item %"cell%" contained within, the following rules are applied in order to determine the displayed colors: 1. If there is an item in the %"cell%" which has a non-Void foreground_color or background_color then these colors are applied to the contents of that %"cell%", otherwise, step 2 is applied. 2. If the column or row at that position has non-Void foreground_color or background_color then these colors are applied to the contents of that %"cell%", otherwise step 3 is applied. 3. As the colors of the item, row and column were all Void, the foreground and background_color of Current is applied to the contents of that %"cell%". Note that for areas of an items %"cell%" that are not filled by item item itself, such as the area of a tree structure, step 1 is ignored and the color calculations begin at step 2."
