4.4 The “Place” Geometry Manager 41 / 75
Method Effect
grid(option=value,. . . ),
Places the widget in a grid, using the
grid configure(option=value,. . . ) specified options.
grid forget(), grid remove() The widget is no longer managed
by the Grid manager, but is not destroyed.
grid info() Returns a dictionary containing the
current options.
grid slaves() Returns a list of widget IDs which
are slaves of the master widget.
grid location(x,y) Returns a (column, row) tuple which
represents the cell in the grid that is
closest to the point (x, y).
grid size() Returns the size of the grid, in the
form of a (column, row) tuple, in
which column is the index of the
first empty column and row the index
of the first empty row.
It is important to note that empty rows and columns are not displayed by the grid
geometry manager, even if a minimum size is specified. Note: The grid manager cannot
be used in combination with the pack manager, as this results in an infinite negociation
loop.
4.4 The “Place” Geometry Manager
The place geometry manager is the most powerful manager of all since it allows exact
placement of the widgets inside a master widget (container). However, it is more
difficult to use and usually represents a great amount of overhead that is rarely needed.
The Place geometry manager allows placement of widgets using either exact coordinates
(with the x and y options), or as a percentage relative to the size of the master
window (expressed as a float in the range [0.0, 1.0]) with the relx and rely options.
The same principle holds for the widget size (using width / height and/or relwidth /
relheight). The options that can be used in the place() method are:
