||

|
||
|
|
|
||
|
|
cursor (str, optional):
|
||
|
|
The cursor that will appear when the mouse is over the
|
||
|
|
progress bar. Defaults to None.
|
||
|
|
|
||
|
|
font (Union[Font, str], optional):
|
||
|
|
The font to use for the progress bar label.
|
||
|
|
|
||
|
|
length (int, optional):
|
||
|
|
Specifies the length of the long axis of the progress bar
|
||
|
|
(width if orient = horizontal, height if if vertical);
|
||
|
|
|
||
|
|
maximum (float, optional):
|
||
|
|
A floating point number specifying the maximum `value`.
|
||
|
|
Defaults to 100.
|
||
|
|
|
||
|
|
mode ('determinate', 'indeterminate'):
|
||
|
|
Use `indeterminate` if you cannot accurately measure the
|
||
|
|
relative progress of the underlying process. In this mode,
|
||
|
|
a rectangle bounces back and forth between the ends of the
|
||
|
|
widget once you use the `Floodgauge.start()` method.
|
||
|
|
Otherwise, use `determinate` if the relative progress can be
|
||
|
|
calculated in advance.
|
||
|
|
|
||
|
|
orient ('horizontal', 'vertical'):
|
||
|
|
Specifies the orientation of the widget.
|
||
|
|
|
||
|
|
bootstyle (str, optional):
|
||
|
|
The style used to render the widget. Options include
|
||
|
|
primary, secondary, success, info, warning, danger, light,
|
||
|
|
dark.
|
||
|
|
|
||
|
|
takefocus (bool, optional):
|
||
|
|
This widget is not included in focus traversal by default.
|
||
|
|
To add the widget to focus traversal, use
|
||
|
|
`takefocus=True`.
|
||
|
|
|
||
|
|
text (str, optional):
|
||
|
|
A string of text to be displayed in the Floodgauge label.
|
||
|
|
This is assigned to the attribute `Floodgauge.textvariable`
|
||
|
|
|
||
|
|
value (float, optional):
|
||
|
|
The current value of the progressbar. In `determinate`
|
||
|
|
mode, this represents the amount of work completed. In
|
||
|
|
`indeterminate` mode, it is interpreted modulo `maximum`;
|
||
|
|
that is, the progress bar completes one "cycle" when the
|
||
|
|
`value` increases by `maximum`.
|
||
|
|
|
||
|
|
mask (str, optional):
|
||
|
|
A string format that can be used to update the Floodgauge
|
||
|
|
label every time the value is updated. For example, the
|
||
|
|
string "{}% Storage Used" with a widget value of 45 would
|
||
|
|
show "45% Storage Used" on the Floodgauge label. If a
|
||
|
|
mask is set, then the `text` option is ignored.

"""A radial meter that can be used to show progress of long
|
||
|
|
running operations or the amount of work completed; can also be
|
||
|
|
used as a dial when set to `interactive=True`.
|
||
|
|
|
||
|
|
This widget is very flexible. There are two primary meter types
|
||
|
|
which can be set with the `metertype` parameter: 'full' and
|
||
|
|
'semi', which shows the arc of the meter in a full or
|
||
|
|
semi-circle. You can also customize the arc of the circle with
|
||
|
|
the `arcrange` and `arcoffset` parameters.
|
||
|
|
|
||
|
|
The meter indicator can be displayed as a solid color or with
|
||
|
|
stripes using the `stripethickness` parameter. By default, the
|
||
|
|
`stripethickness` is 0, which results in a solid meter
|
||
|
|
indicator. A higher `stripethickness` results in larger wedges
|
||
|
|
around the arc of the meter.
|
||
|
|
|
||
|
|
Various text and label options exist. The center text and
|
||
|
|
meter indicator is formatted with the `meterstyle` parameter.
|
||
|
|
You can set text on the left and right of this center label
|
||
|
|
using the `textleft` and `textright` parameters. This is most
|
||
|
|
commonly used for '$', '%', or other such symbols.
|
||
|
|
|
||
|
|
If you need access to the variables that update the meter, you
|
||
|
|
you can access these via the `amountusedvar`, `amounttotalvar`,
|
||
|
|
and the `labelvar`. The value of these properties can also be
|
||
|
|
retrieved via the `configure` method.
