Description:

The PtGauge superclass provides common resources for gauge-like widgets, which are capable of displaying a range of values.

New resources:

Resource	C type	Pt type	Default
Pt_ARG_GAUGE_FLAGS	`short int`	Flag	0
Pt_ARG_GAUGE_FONT	`char *`	String	`"helv12"`
Pt_ARG_GAUGE_H_ALIGN	`unsigned char`	Scalar	Pt_CENTER
Pt_ARG_GAUGE_MAXIMUM	`long`	Scalar	100
Pt_ARG_GAUGE_MINIMUM	`long`	Scalar	0
Pt_ARG_GAUGE_ORIENTATION	`char`	Scalar	Pt_HORIZONTAL
Pt_ARG_GAUGE_V_ALIGN	`unsigned char`	Scalar	Pt_CENTER
Pt_ARG_GAUGE_VALUE	`long`	Scalar	0
Pt_ARG_GAUGE_VALUE_PREFIX	`char *`	String	NULL
Pt_ARG_GAUGE_VALUE_SUFFIX	`char *`	String	NULL

Pt_ARG_GAUGE_FLAGS

C type	Pt type	Default
`short int`	Flag	0

Possible values:

Pt_SHOW_VALUE: Indicates whether or not the value of the gauge will be displayed.
Pt_VALUE_XOR: XOR the value display with the background (i.e. invert the fill of the type face).
Pt_GAUGE_MAX_ON_TOP Pt_GAUGE_MAX_ON_RIGHT Pt_GAUGE_MAX_ON_LEFT Pt_GAUGE_MAX_ON_BOTTOM: The position of the maximum value.

The default setting for this resource is 0; that is, no flags have been set.

Pt_ARG_GAUGE_FONT

C type	Pt type	Default
`char *`	String	`"helv12"`

The font used for displaying the value, title, and any other text.

Pt_ARG_GAUGE_H_ALIGN

C type	Pt type	Default
`unsigned char`	Scalar	Pt_CENTER

Controls horizontal alignment. Possible values are:

Pt_LEFT: Draw the value aligned to the left edge.
Pt_RIGHT: Draw the value aligned to the right edge.
Pt_CENTER: Draw the value centered.

Pt_ARG_GAUGE_MAXIMUM

C type	Pt type	Default
`long`	Scalar	100

The maximum value of the gauge.

Pt_ARG_GAUGE_MINIMUM

C type	Pt type	Default
`long`	Scalar	0

The minimum value of the gauge.

Pt_ARG_GAUGE_ORIENTATION

C type	Pt type	Default
`char`	Scalar	Pt_HORIZONTAL

Indicates whether the gauge will be drawn vertically or horizontally. Possible values:

Pt_HORIZONTAL
Pt_VERTICAL

Pt_ARG_GAUGE_V_ALIGN

C type	Pt type	Default
`unsigned char`	Scalar	Pt_CENTER

Controls vertical alignment. Possible values are:

Pt_TOP: Draw the value aligned with the top edge.
Pt_BOTTOM: Draw the value aligned with the bottom edge.
Pt_CENTER: Draw the value centered.

Pt_ARG_GAUGE_VALUE

C type	Pt type	Default
`long`	Scalar	0

The gauge's current value.

Pt_ARG_GAUGE_VALUE_PREFIX

C type	Pt type	Default
`char *`	String	NULL

Text prefixed to the value displayed. For example, Red: would result in Red:35.

Pt_ARG_GAUGE_VALUE_SUFFIX

C type	Pt type	Default
`char *`	String	NULL

Text appended to the value displayed. For example, % would result in 35%.

Inherited resources:

If the widget modifies an inherited resource, the "Default override" column indicates the new value. This modification affects any subclasses of the widget.
