Specifies the desired long dimension of the ProgressBar in screen
units (i.e. any of the forms acceptable to Tk_GetPixels). For vertical
ProgressBars this is the ProgressBars height; for horizontal scales it
is the ProgressBars width. The default length is calculated from the
values of -padx, -borderwidth, -highlightthickness and the
difference between -from and -to.
A real value specifying the resolution for the scale. If this value is greater
than zero then the scale's value will always be rounded to an even multiple of
this value, as will tick marks and the endpoints of the scale. If the value is
less than zero then no rounding occurs. Defaults to 1 (i.e., the value will be
Specifies the reference to a scalar variable to link to the ProgressBar.
Whenever the value of the variable changes, the ProgressBar will upate
to reflect this value. (See also the value method below.)
Specifies the desired narrow dimension of the ProgressBar in screen
units (i.e. any of the forms acceptable to Tk_GetPixels). For
vertical ProgressBars this is the ProgressBars width; for horizontal
bars this is the ProgressBars height. The default width is derived
from the values of -borderwidth and -pady and -highlightthickness.
