'''wm geometry''' ''window ?newGeometry?''

If ''newGeometry'' is specified, then the geometry of ''window'' is changed and an empty string is returned.
Otherwise the current geometry for ''window'' is returned (this is the most recent geometry specified either by manual resizing or in a '''wm geometry''' command).
''NewGeometry'' has the form ''=width'''''x'''''height'''''+'''''x'''''+'''''y'', where any of ''='', ''width'''''x'''''height'', or '''''+'''''x'''''+'''''y'' may be omitted.
''Width'' and ''height'' are positive integers specifying the desired dimensions of ''window''.
If ''window'' is gridded (see GRIDDED GEOMETRY MANAGEMENT below) then the dimensions are specified in grid units; otherwise they are specified in pixel units.
The ''x'' and ''y'' values specify the desired location of ''window'' on the screen, in pixels.
If ''x'' is preceded by ''+'', it specifies the number of pixels between the left edge of the screen and the left edge of ''window'' 's border; if preceded by ''-'' then ''x'' specifies the number of pixels between the right edge of the screen and the right edge of ''window'' 's border.
If ''y'' is preceded by ''+'' then it specifies the number of pixels between the top of the screen and the top of ''window'' 's border; if ''y'' is preceded by ''-'' then it specifies the number of pixels between the bottom of ''window'' 's border and the bottom of the screen.
If ''newGeometry'' is specified as an empty string, then any existing user-specified geometry for ''window'' is cancelled, and the window will revert to the size requested internally by its widgets.
