note description: "[ Cell consisting of a text label with optional pixmap. The rules governing the position of text and pixmap in relation to Current are as follows: Both text and pixmap are always drawn completely within the area goverened by left_border, right_border, top_border and bottom_border, which will be referred to as the redraw_client_area in this description. Note that text may be automatically ellipsized (clipped with three dots) to ensure this. pixmap is always displayed to the very left edge of redraw_client_area and centered vertically. The only method of overriding this behavior is to set a custom layout_procedure. text may be aligned within redraw_client_area via the following features: 'align_text_left', align_text_center, align_text_right, align_text_top, align_text_vertically_center and align_text_bottom. Note that the text alignment has no effect on the position of the pixmap which follows the rules listed above. A layout_procedure may be set which permits you to override the position of text and pixmap by computing the redraw positions manually. The drawing is clipped to redraw_client_area although there is no restriction on the positions that may be set for text and pixmap. ]" legal: "See notice at end of class." status: "See notice at end of class." date: "$Date: 2015-12-17 04:34:17 -0900 (Thu, 17 Dec 2015) $" revision: "$Revision: 98279 $" class interface EV_GRID_LABEL_ITEM create default_create -- Standard creation procedure. -- (from EV_ANY) require -- from ANY True ensure then -- from EV_ANY is_coupled: implementation /= Void is_initialized: is_initialized default_create_called: default_create_called is_in_default_state: is_in_default_state make_with_text (a_text: READABLE_STRING_GENERAL) -- Create Current and assign a_text to text require a_text_not_void: a_text /= Void ensure text_set: text.same_string_general (a_text) feature -- Access attached_parent: EV_GRID -- Attached grid in which Current is contained. -- (from EV_GRID_ITEM) require -- from EV_GRID_ITEM parent /= Void background_color: detachable EV_COLOR -- Color displayed behind foreground features. -- (from EV_GRID_ITEM) require -- from EV_GRID_ITEM not_destroyed: not is_destroyed column: EV_GRID_COLUMN -- Column to which current item belongs. -- (from EV_GRID_ITEM) require -- from EV_GRID_ITEM not_destroyed: not is_destroyed is_parented: is_parented ensure -- from EV_GRID_ITEM column_not_void: Result /= Void data: detachable ANY -- Arbitrary user data may be stored here. -- (from EV_ANY) default_identifier_name: STRING_32 -- Default name if no other name is set. -- (from EV_IDENTIFIABLE) ensure -- from EV_IDENTIFIABLE result_not_void: Result /= Void result_not_empty: not Result.is_empty no_period_in_result: not Result.has ('.'.to_character_32) foreground_color: detachable EV_COLOR -- Color of foreground features like text. -- (from EV_GRID_ITEM) require -- from EV_GRID_ITEM not_destroyed: not is_destroyed full_identifier_path: STRING_32 -- Full name of object by prepending path of parent -- Uses '.' as a separator. -- (from EV_IDENTIFIABLE) ensure -- from EV_IDENTIFIABLE result_not_void: Result /= Void result_correct: parent = Void implies Result.is_equal (identifier_name) result_correct: attached parent as l_parent implies Result.is_equal (l_parent.full_identifier_path + ".".as_string_32 + identifier_name) generating_type: TYPE [detachable EV_GRID_LABEL_ITEM] -- Type of current object -- (type of which it is a direct instance) -- (from ANY) ensure -- from ANY generating_type_not_void: Result /= Void generator: STRING_8 -- Name of current object's generating class -- (base class of the type of which it is a direct instance) -- (from ANY) ensure -- from ANY generator_not_void: Result /= Void generator_not_empty: not Result.is_empty height: INTEGER_32 -- Height of Current in pixels. -- (from EV_GRID_ITEM) require -- from EV_GRID_ITEM not_destroyed: not is_destroyed parented: is_parented ensure -- from EV_GRID_ITEM result_non_negative: Result >= 0 horizontal_indent: INTEGER_32 -- Horizontal distance in pixels from left edge of Current to left edge of column. -- This may not be set, but the value is determined by the current tree structure -- of parent and row. -- (from EV_GRID_ITEM) require -- from EV_GRID_ITEM not_destroyed: not is_destroyed parented: is_parented ensure -- from EV_GRID_ITEM not_parent_tree_enabled_implies_result_zero: attached parent and then ((attached parent as l_parent and then not l_parent.is_tree_enabled) implies Result = 0) parent_tree_enabled_implies_result_greater_or_equal_to_zero: attached parent and then ((attached parent as l_parent and then l_parent.is_tree_enabled) implies Result >= 0) identifier_name: STRING_32 -- Name of object -- If no specific name is set, default_identifier_name is used. -- (from EV_IDENTIFIABLE) ensure -- from EV_IDENTIFIABLE result_not_void: Result /= Void result_not_empty: not Result.is_empty no_period_in_result: not Result.has ('.'.to_character_32) default_name_available: not has_identifier_name_set implies Result.is_equal (default_identifier_name) parent: detachable EV_GRID -- Grid in which Current is contained if any. -- (from EV_GRID_ITEM) require -- from EV_IDENTIFIABLE not_destroyed: not is_destroyed ensure -- from EV_IDENTIFIABLE correct: has_parent implies Result /= Void correct: not has_parent implies Result = Void required_width: INTEGER_32 -- Width in pixels required to fully display contents, based -- on current settings. -- Note that in some descendents such as EV_GRID_DRAWABLE_ITEM, this -- returns 0.
