Table (lv_table)

Overview

Tables, as usual, are built from rows, columns, and cells containing texts.

The Table object is very lightweight because only the texts are stored. No real objects are created for cells but they are just drawn on the fly.

The Table is added to the default group (if it is set). Besides the Table is an editable object to allow selecting a cell with encoder navigation too.

Parts and Styles

LV_PART_MAIN The background of the table uses all the typical background style properties.
LV_PART_ITEMS The cells of the table also use all the typical background style properties and the text properties.

Usage

Set cell value

The cells can store only text so numbers need to be converted to text before displaying them in a table.

lv_table_set_cell_value(table, row, col, "Content"). The text is saved by the table so it can be even a local variable.

Line breaks can be used in the text like "Value\n60.3".

New rows and columns are automatically added is required

Rows and Columns

To explicitly set number of rows and columns use lv_table_set_row_cnt(table, row_cnt) and lv_table_set_col_cnt(table, col_cnt)

Width and Height

The width of the columns can be set with lv_table_set_col_width(table, col_id, width). The overall width of the Table object will be set to the sum of columns widths.

The height is calculated automatically from the cell styles (font, padding etc) and the number of rows.

Merge cells

Cells can be merged horizontally with lv_table_add_cell_ctrl(table, row, col, LV_TABLE_CELL_CTRL_MERGE_RIGHT). To merge more adjacent cells call this function for each cell.

Scroll

If the label's width or height is set to LV_SIZE_CONTENT that size will be used to show the whole table in the respective direction. E.g. lv_obj_set_size(table, LV_SIZE_CONTENT, LV_SIZE_CONTENT) automatically sets the table size to show all the columns and rows.

If the width or height is set to a smaller number than the "intrinsic" size then the table becomes scrollable.

Events

LV_EVENT_VALUE_CHANGED Sent when a new cell is selected with keys.
LV_EVENT_DRAW_PART_BEGIN and LV_EVENT_DRAW_PART_END are sent for the following types:
- LV_TABLE_DRAW_PART_CELL The individual cells of the table
  - part: LV_PART_ITEMS
  - draw_area: area of the indicator
  - rect_dsc
  - label_dsc
  - id: current row × col count + current column

See the events of the Base object too.

Learn more about Events.

Keys

The following Keys are processed by the Tables:

LV_KEY_RIGHT/LEFT/UP/DOWN/ Select a cell.

Note that, as usual, the state of LV_KEY_ENTER is translated to LV_EVENT_PRESSED/PRESSING/RELEASED etc.

lv_table_get_selected_cell(table, &row, &col) can be used to get the currently selected cell. Row and column will be set to LV_TABLE_CELL_NONE no cell is selected.
