Detailed Description

A gauge is a horizontal or vertical bar which shows a quantity (often time).

wxGauge supports two working modes: determinate and indeterminate progress.

The first is the usual working mode (see SetValue() and SetRange()) while the second can be used when the program is doing some processing but you don't know how much progress is being done. In this case, you can periodically call the Pulse() function to make the progress bar switch to indeterminate mode (graphically it's usually a set of blocks which move or bounce in the bar control).

wxGauge supports dynamic switch between these two work modes.

There are no user commands for the gauge.

Styles

This class supports the following styles:

• wxGA_HORIZONTAL:
  Creates a horizontal gauge.
• wxGA_VERTICAL:
  Creates a vertical gauge.
• wxGA_SMOOTH:
  Creates smooth progress bar with one pixel wide update step (not supported by all platforms).

Constructor & Destructor Documentation

wxGauge::wxGauge

(

)

Default constructor.

wxGauge::wxGauge	(	wxWindow *	parent,
		wxWindowID	id,
		int	range,
		const wxPoint &	pos = wxDefaultPosition,
		const wxSize &	size = wxDefaultSize,
		long	style = wxGA_HORIZONTAL,
		const wxValidator &	validator = wxDefaultValidator,
		const wxString &	name = wxGaugeNameStr
	)

Constructor, creating and showing a gauge.

Parameters:

parent	Window parent.
id	Window identifier.
range	Integer range (maximum value) of the gauge. See SetRange() for more details about the meaning of this value when using the gauge in indeterminate mode.
pos	Window position.
size	Window size.
style	Gauge style.
validator	Window validator.
name	Window name.

		const wxSize &	size = wxDefaultSize,
		long	style = wxGA_HORIZONTAL,

Creates the gauge for two-step construction.

See wxGauge() for further details.

int wxGauge::GetBezelFace

(

)

const

Returns the width of the 3D bezel face.

注意:

This method is not implemented (returns 0) for most platforms.

int wxGauge::GetRange

(

)

const

Returns the maximum position of the gauge.

int wxGauge::GetShadowWidth

(

)

const

Returns the 3D shadow margin width.

注意:

This method is not implemented (returns 0) for most platforms.

int wxGauge::GetValue

(

)

const

Returns the current position of the gauge.

bool wxGauge::IsVertical

(

)

const

Returns true if the gauge is vertical (has wxGA_VERTICAL style) and false otherwise.

virtual void wxGauge::Pulse

(

)

[virtual]

Switch the gauge to indeterminate mode (if required) and makes the gauge move a bit to indicate the user that some progress has been made.

注:

After calling this function the value returned by GetValue() is undefined and thus you need to explicitly call SetValue() if you want to restore the determinate mode.

void wxGauge::SetBezelFace

(

int

width

)

Sets the 3D bezel face width.

注意:

This method is not implemented (doesn't do anything) for most platforms.

参照:

GetBezelFace()

void wxGauge::SetRange

(

int

range

)

Sets the range (maximum value) of the gauge.

This function makes the gauge switch to determinate mode, if it's not already.

When the gauge is in indeterminate mode, under wxMSW the gauge repeatedly goes from zero to range and back; under other ports when in indeterminate mode, the range setting is ignored.

GetRange()

void wxGauge::SetShadowWidth

(

int

width

)

Sets the 3D shadow width.

注意:

This method is not implemented (doesn't do anything) for most platforms.

void wxGauge::SetValue

(

int

pos

)

Sets the position of the gauge.

The pos must be between 0 and the gauge range as returned by GetRange(), inclusive.

This function makes the gauge switch to determinate mode, if it was in indeterminate mode before.

Parameters:

pos	Position for the gauge level.
