GridView is a user-defined view structured as a grid of equal-sized
cells. Abstract methods are provided for drawing the contents of a cell
and detecting mouse clicks in a cell based on their row and column
Note: Don't confuse this with the Grid class, which is a container for laying out other components in a grid.
The extent of a GridView is managed through the num_rows, num_columns and cell_size properties. The extent property inherited from ScrollableView should not be changed directly.
- GridView(num_rows, num_columns, cell_size)
- Creates a grid view whose extent initially covers the specified number of rows and columns.
- Number of rows in the view's extent.
- Number of columns in the view's extent.
- The size of each cell. A tuple (width, height).
- Color with which to fill the background of a cell before calling draw_cell(), or None for no automatic background fill.
- draw_cell(canvas, row_number, column_number, cell_rect)
- Should draw the specified cell inside the given rectangle.
- click_cell(row_number, column_number, event)
- Called when a mouse_down event occurs in a cell.
- cell_rect(row_number, column_number)
- Returns the rectangle corresponding to the cell at the given row and column numbers.
- Returns a tuple (row_number, column_number) indicating the cell in which the given point lies.
